Later that day, Clara re-joined Sherlock and Tyler back in the living room where they were still sorting through the books, even some of the books they had already been through. "A book that everybody would own," Sherlock was muttering to himself, running his hands through his hair as he stared at his own collection of books.

"How about a Dictionary?" Clara suggested, taking a seat at the desk, feeling and looking less tired then she had, "Maybe a Bible?"

Sherlock clicked his fingers, grabbing his own Oxford Dictionary, a copy of the Bible, and a third book, carrying them over to one of the crates and opening the Dictionary, opening it to the correct page, "Fifteen," he muttered as the girls watched him, waiting to see if this one would work, "Entry one".

Frowning, Sherlock continued going through the three books before slamming the last book, the Bible, shut in frustration, making Tyler sighed as she realized that none of the three books had helped, just as John walked into the flat. "I need some air," Sherlock said, running a hand through his hair, looking at the girls and John, "We're going out tonight."

"Actually," John hesitated, smiling, "I've, uh, got a date."

"Well done, Dr Watson," Tyler laughed, making John grin.

"A what?" Clara echoed, her eyebrows furrowed.

"What?" Sherlock frowned, staring at him as if he had never heard the word before.

John gave him a look, "It's when two people who like each other go out and have fun," he told him, making Tyler hide her smile.

"That's what I was suggesting," Sherlock replied, looking confused.

"Not quite," Tyler shook her head, looking amused.

"No, it wasn't," John nodded, giving Sherlock a strange look, "At least I hope not..."

Clara broke into the conversation with a curious look, "Where are you taking her?"

"Er, cinema."

"Oh, dull, boring, predictable," Sherlock said, reaching inside his pocket and took a piece of paper out, handing it to John, "Why don't you try this?" Tyler gave him a questioning look as she noticed his smile as he turned away from John, "In London for one night only."

John looked down at the piece of paper and chuckled, "Thanks, but I don't come to you for dating advice," he held out his hand with the paper in it, giving the girls a clear view of it.

"You know, Johnny," Tyler started, smiling slightly, "If I went on a date and he took me to the circus, I would definitely come to the conclusion that he had a good sense of humour. I mean, the movies is alright, good place to sneak a kiss, but then she'll think you're only trying to get off. Take her to the circus, she'll love it."

"You think so?" he asked after a moment, looking unsure as Sherlock pretend not to listen when he was really paying close attention.

"Oh, trust me on this, Johnny," Tyler nodded, "The first date is the most important one, it's the one that's going to live on in her memory for years to come. It's what she's going to judge all her viewpoints of you on, so it has to be special."

"Right," John nodded, looking more sure as he turned to Sherlock, "Can you get me two tickets for tonight?"

"Of course," he said, Clara frowned slightly as she noticed something... off about his voice, as if he had a reason for sending John to the circus. What had Tyler done?

"Thanks," John smiled, looking relived, "Well, I guess I'd better get ready."

He quickly turned and hurried off to his bedroom, leaving Clara to frown at Sherlock and Tyler, "What did you two just do?" She sighed as soon as she was sure John wouldn't hear.

"Nothing." Tyler smiled innocently.

"What did you do?" Clara asked, this time more stern, crossing her arms.

"Simply, made sure he took his date to the right place," Tyler replied simply.

"There was no way he was going to listen to me. But, Tyler's a woman - he assumes that basing date ideas off what you say will be a good idea. Which is exactly what I wanted to happen." Sherlock finished for her.

"Brilliant," she groaned, looking as if she wanted to slap them.

"Please, you want this date to go sideways and you know it." Tyler muttered, looking over at Sherlock who nodded in agreement at her deduction.

"What?" Clara frowned at them and Tyler tossed her a winning smile.

"Nothing."

"Onto the next part in the plan," Sherlock smirked, "How would you two like to go on a date with me tonight?"

"Let me guess," Clara pretended to think about it, "You're taking us to the... circus?"

"The Chinese circus," Sherlock corrected.

"Surprise, surprise," Tyler rolled her eyes. "And while we're on this..." she battered her long eyelashes suggestively, "Oh, so romantic date, we'll also be ruining John's date, and trying to solve the case, yes?"

"You did say that the first date was the most important one," he reminded her, "And that it will be the most memorable, will you ever forget a date such as this?"

"I guess," She narrowed her eyes, assessing him, finally she gave in with a deep sigh. "It's a date."

They both looked back at Clara, she sighed, "Might as well."

"Good," he nodded, "Now go and get changed into something that you would wear on a date."

"I haven't been on a date in almost two years," Tyler let out an incredulous laugh. "I don't think I even own a dress."

Sherlock sighed, giving her a look, "Just wear something."

Tyler looked at him, frowning at his snippy tone, "you definitely won't be getting a second date with an attitude like that." She smirked, playfully. Sherlock gave her a small glare, making her sigh and hold up her hands, "Fine, fine, I'm sorry. I'll get changed."

"Come on," Clara laughed, taking Tyler's hand and tugged her along to head to their own flat.

Sherlock frowned slightly to himself as he watched Tyler leave the room, heading back to her own flat next door. There was that feeling again, the same feeling he had the other day when John had made her laugh, what was it? Why did he keep feeling it? Why was it that he had even asked her on a date in the first place when they simply could have gone along without even needing to specify it.

Whatever was going on, it was definitely proving to be very irritating.

~*~

At six o'clock that night, Sherlock and the girls hailed a cab and arrived at the building that the circus was being held in, quickly finding John already there, standing beside a woman with brown hair at the ticket collecting window.

Tyler definitely didn't own a dress, but she was able to find something suitable. She was dressed in a pair of black skinny jeans, a gold, flowy top that was decorated with gold sequin, a black leather jacket, and a pair of black platform heels that came up over her ankle with two buckles. She had also put her hair half up in a clip, red lipstick, eye shadow that gave her eyes a smokey look, and in her ears, a pair of ruby studs. Sherlock hadn't bothered to change his clothing, but he had given his nod of approval when he saw Tyler's outfit before they left the flat.

Clara was dressed in a pair of light skinny jeans, a purple, flowy top that was decorated with a ruffle down the front, a black cardigan. and a pair of black flats that had a black flower on the strap. She had her hair in loose curls, red wine lipstick, eye shadow that gave her a smokey eye look, eyeliner, and a pair of black feather earrings.

"Shall we," Clara looped one arm through Sherlock's smirking up at his confused face.

"We shall." Tyler was the one to respond, looping her arm through Sherlock's free one and together they led him inside.

"Er, Holmes," John was saying to the ticket holding as he took his wallet out of his jacket pocket.

"Actually, I have five in that name," the ticket holding told him after rummaging around and finding an envelope marked Holmes.

"No, I don't think so," John frowned, looking confused, "We only booked two."

"And then I phoned back and got one for myself and the girls," Sherlock said, walking over to them with both girls on each arm, making John stare at them.

His lips twitched into a half smile as a hand came up to rub at the back of his head, "Clara, you look... great." He finally decided on.

Clara's eyes widened slightly at the compliment, ducking her head to look down at the outfit and hide her smile, "thank you."

Sherlock looked between the two of them with calculating eyes and cleared his throat, before untangling from each girl and offering his hand to the woman, "I'm Sherlock."

The woman stared at him, looking a little confused as she shook his hand, "Uh, hi," she smiled nervously.

"Hello," he greeted, giving her a fake smile before turning and walking away, quickly followed after an annoyed looking John who gave his date a apologetic smile as he passed her.

Clara sighed and turned back to the woman, "I'm sorry about Sherlock," she smiled, "He's a little eccentric, if you catch my meaning?"

"Oh, it's alright," she shook her head, holding out her hand to the brunette, smiling, "I'm Sarah."

"Nice to meet you," Clara smiled, shaking Sarah's offered hand, "I'm Clara, Clara Hudson. And this is my friend Tyler Jackson." Sarah then turned to shake Tyler's hand as Clara introduced them.

"Hi," Tyler nodded politely.

"So, are you and Sherlock..." Sarah trailed off as they began heading towards the stairs that the boys had vanished up. Clara and Tyler on either side of her, but her eyes were on Tyler.

Tyler's eyes widened in shock, looking deeply embarrassed, "No, not at all," she quickly told her, shaking her head, "Sherlock and I just work together. We're also neighbors, but we're most definitely not dating each other. I don't really do dates anymore, and I'm sure Sherlock does either." She said, remembering the conversation they had in the restaurant their first case together.

"I'm sorry," Sarah said, giving her an apologetic look, "I just assumed that the two of you were here on a date together with how the two of you just... fit."

"What do you mean?" she frowned, pausing as she looked at her.

"Nothing," Sarah waved it off, "I guess I just imagined it. Are you and Sherlock together then?" She turned to Clara, half of her hoping she'd say yes considering the look she noticed John gave the brunette.

"Um, no." Clara laughed at the thought.

Tyler continued to frown before shaking her head and continuing upstairs, finding Sherlock and John standing a couple of steps above them, neither of them seeming not to have noticed them as they appeared to be in the middle of arguing. "What?" Sherlock was asking, looking confused as he frowned at John.

John glared at Sherlock, seeming to have lost his patience, "...while I'm trying to get off with Sarah!" he shouted. Clara cleared her throat loudly, making John jump and look behind him to see them standing there. He flashed Sarah an awkward smile, "Hey! Ready?"

Sherlock rolled his eyes at them and began making his way up the rest of the stairs, Tyler and Clara quickly moved around John and followed him, "Care to explain what you and John were having a lovely little chat about?" Clara asked him.

Sherlock cast her a look, ignoring her question as they reached the top of the stairs and entered into a large, theater like room with a large ring in the middle of the room that had lit candles all around it, along with thirty or more people standing around the side.

A moment later, John and Sarah joined them as Sherlock began looking around the room, "You said circus," John said softly to them so Sarah wouldn't hear him as he spoke over his shoulder, "This is not a circus. Look at the size of this crowd. Guys, this is..." he cast a distasteful look at the room, "Art," he grimaced.

"What's wrong with art?" Tyler asked.

"This is not there day job," Sherlock told him before he could say something to Tyler.

"No, sorry, I forgot," John rolled his eyes at him, "They're not a circus, they're a gang of international smugglers."

"Shh," Clara hushed them, "The shows about to start."

As if on cue, one of the performers began tapping a small drum, signaling the arrival of a Chinese woman dressed from head to foot in an ornate style costume with heavily painted face. As she walked out into the middle of the stage, Tyler quirked an eyebrow and looked over at John in an I told you so manner.

The woman raised her hand and the drum beat died down, only to be replaced by another a moment later with the sound of a larger drum being beaten, this time at a quick beat while the woman walked over to a large object off to the side of the stage, covered by a cloth. She pulled the cloth away to reveal a large, antique-looking crossbow like object, sitting on a stand.

The woman paused, casting her eyes over the audience, Tyler frowned slightly as she almost seemed to stop briefly on her, almost as if she had recognized her, but as quickly as the thought had come, the woman had looked away and picked up a long, wooden stick with white feathers on one end, and a sharp metal point at the other. She lifted it up for them all to see before turning to the crossbow and slotted it into place. Once it was in the correct place, she turned back to the audience and pulled a white feather from her headdress, dropping it into a bowl on the crossbow.

As soon as the feather hit the bowl, the arrow shot out and hit a bored across the stage, hitting it almost dead center. The audience gasped and jumped, including Clara who accidentally jumped right into Sherlock who had been standing behind her while Sarah started laughing from beside John at herself.

"Sorry," Clara softly said to Sherlock, taking a quick step forward to put some distance between them both.

Back on the stage, a man stepped out into the middle of the stage, dressed all in armor, and wearing a Chinese mask that covered his face from view. Two other men stepped out and began chaining him to the bored that they had used as a target before.

"Classis Chinese escapology act," Sherlock leaned forward and whispered in Tyler's ear, making her jump, as she felt his breath on her neck, "The crossbow's on a delicate string. The warrior has to escape his bonds before it fires."

They watched as the woman up on stage placed another arrow into the crossbow, some members of the audience gasped again as the chained man started trying to shout out, struggling against the chains. Sarah jumped and grabbed hold of John's arm as a cymbal was smashed together.

"Oh, God!" she gasped, laughing at herself, "I'm sorry!" John chuckled at her, smiling down at his arm as he noticed her still holding onto him as the Chinese woman picked up a small knife and showed it to the audience.

"She splits the sandbag, the sand pours out," Sherlock whispered to Tyler again, "Gradually, the weight lowers into the bowl," as he spoke, the woman on the stage did everything he said as the chained man began shouting again.

"Show off," Tyler whispered to Sherlock, giving him a small smile over her shoulder, "You just can't help yourself, can you?"

Sherlock didn't answer as he smirked and grabbed her hand, "Come on," he turned and began pulling her away, leading her toward the back of the stage while everyone else in the audience was focused on what was going on, on the stage.

"You should know Sherly," Tyler remarked softly, her tone of voice making it clear to Sherlock she was going to make a smart ass comment. "I don't put out on the first date, especially in the middle of it." Sherlock simply tossed her a look as he bent down, making her sigh and hold up her hands.

They continued their search of the backstage when Sherlock suddenly grabbed Tyler's arm, making her stop and look over to him to see him staring at something that looked like a person dressed in their costume, but as they looked down, they noticed that it was just a stand with a costume on it. They both exchanged relieved looks as they heard the sound of the Chinese woman say something from the other side of the curtain.

"...the deadly Chinese bird-spider," she announced as the audience clapped.

Sherlock and Tyler quickly dashed over to the side of the curtain, carefully making sure that no one could see them as they peeked around to see a man with a long, red band of fabric tied around his waist fell from the ceiling, rolling through the air. The audience applauded as he stopped a few feet from hitting the floor.

"Well, well," Sherlock muttered, watching as the man began flying around the ring with the aid of fabric, leaving the audience to watch, opened mouthed.

Suddenly, the sound of a door opening sounded, and Sherlock quickly grabbed Tyler before she could react and pulled her with him behind a clothing rack, quickly kneeling down as they used the clothing to hide them from view as someone entered the room. Once they were sure they wouldn't be seen, they peeked over the top of the clothing rake to see the Chinese woman checking her phone, but as Tyler shifted to get a better look, she accidentally knocked one of the clothes hangers loose, and sending it to the floor.

The woman's head snapped toward them just as Sherlock and Tyler ducked back down, holding their breath as they waited to be caught, but after a tense few seconds, they heard the woman's footsteps heading away from them and the sound of the door closing behind her.

"That was close," Tyler breathed, feeling her heat racing madly, "Very close. Sherlock..." she frowned as she looked beside her to see Sherlock rummaging around in a bag by his feet with half a dozen cans of spray paint inside. He picked one of the cans up, turning it over to see the label read 'Michigan' with a yellow band around the bottom.

"Found you," Sherlock said softly in a sing-song voice, making Tyler give him a slightly odd look. He quickly stood and pushed the clothes out of his way as he stepped through the rack, shaking the can in his hand as he walked over to one of the dressing table mirrors and sprayed a line of yellow paint across it.

"Masterpiece, Sherlock," Tyler remarked, following after him as she stood back and eyed the mirror, "People everywhere will be..." but she suddenly trailed off as her eyes widened, catching sight of warrior costume that they had thought was a person behind them move.

Sherlock frowned, noticing her face as he turned around just as the person now wearing the costume leaped at him and began slashing his sword through the air, forcing Sherlock to jump backwards, managing to shove Tyler out of the way before she could be slashed in two.

"Use the can, Sherlock!" she shouted as she regained her balance, looking over to see Sherlock duck, just missing being hit. Following her advice, he quickly brought the can of spray paint up with him as he rose, using it to block the sword before ducking once more and managing to land a punch, but he left himself open and the man kicked him hard in the stomach.

Sherlock cried out in pain, doubling over slightly as Tyler could only stand back and wait for a chance to distract the man, but it was still too dangerous for Sherlock while the man still had his sword for her to really do anything to help. The last thing she wanted to do was end up accidentally knocking the man into Sherlock and giving him a better chance of killing him.

As luck would have it, the man dropped the sword as he lunged for Sherlock's throat, giving Tyler the chance to leap of the man's back while Sherlock tried to pull the man's hands away from his throat. The man gave a sharp turn, sending Tyler who had been struggling to get a grip around his neck, flying off him and through the stage curtain, and off the stage into the ring, to be joined a moment later by Sherlock.

Both Tyler and Sherlock blinked, looking slightly dazed, but Sherlock didn't have time to recover from his sudden fall off the stage as the man who was still attacking him flipped off the stage and ran at Sherlock, preparing to stab him with his recovered sword when John suddenly came running into the action, pushing the man back into the edge of the stage.

The man lashed out at John and kicked him in the stomach, sending him stumbling away, clutching his stomach. Tyler scrambled to her feet and tried to trip the man up, but seeing what she was trying to do, he hit her with a blow to her stomach, surprising her enough to trip her up, and almost cajsing her to face plant the floor. The man quickly ran back over to Sherlock, raising his sword again when Clara ran up to him and smacked him with the end of a broom over the back of his head.

The man cried out in pain, but before he could react, she hit him again in his ribs, and then a second blow in his ribs, sending him crashing to the floor, groaning in pain, half unconscious.

Sherlock slowly pulled himself upright from the floor, still looking half dazed as he grabbed the man's foot and pulled his shoe off to reveal the Tong's tattoo. He quickly scrambled to his feet, hurrying over to Tyler who was clutching her stomach as she struggled to regain her breath after being winded, and helped her to stand while Clara helped John.

John nodded at her and then went over to where Sarah was watching with wide eyes, "Come on," John gasped, bent over as he and Sarah started for the exited. He looked back at Clara, and she cast a look back at the other two. Seeing that Sherlock had Tyler, she hurried after John and Sarah.

Tyler grasped hold of Sherlock's arm as she used it to pull herself up and allowed him to help her hurry after John, Clara, and Sarah. "Come on!" Sherlock called, taking the lead, "Let's go!"

"I sent a couple of cars," Dimmock informed the boys, Tyler, Clara, and a still very shocked Sarah as he stormed through Scotland Yard toward his desk, "The old hall is totally deserted."

"Look, I saw the mark at the circus," Sherlock told him, trying to get it into Dimmock's head that what they were trying to tell him was serious, "Tyler saw it..."

"It's true, Inspector," Tyler nodded, having caught sight of the tattoo while she had been trying to get her breath back after being hit in the stomach. Her stomach was still aching, and she had a feeling that she would be given a nasty bruise by the morning, but John had checked her over and assured her that she hadn't broken anything.

"That tattoo that we saw on the two bodies," Sherlock continued, "The mark of the Tong'."

"Lukis and Van Coon were part of a smuggling operation," John explained to Dimmock as Sarah looked in-between them, still looking quite shaken as she held on tightly to John's arm, "Now; one of them stole something when they were in China, something valuable."

"And for obvious reasons, they want it back," Tyler added, nodding along with John, "The circus performers are a gang who's members were sent here to get this valuable item back, and by any means possible."

Dimmock raised his eyebrows at them, frowning slightly, "Get what back?" he asked.

Sherlock didn't answer as he bit his lip and looked away, angrily as John hesitated, sharing a wary look with Tyler and Clara, "We don't know," Clara replied after a moment.

"You don't know," Dimmock said in an almost mocking tone as he stared at them, shaking his head as he took a seat behind his desk, "Mr Holmes, I've done everything you asked. Lestrade, he seems to think your advice is worth something," Sherlock lifted his head, a small smile making its way across his face as he listened, "I gave the order for a raid. Please tell me I'll have something to show for it, other than a massive bill for overtime."

Once they had reassured Dimmock that they would find him proof, they returned to Baker Street with Sarah still following, but thankfully she had finally managed to calm down and appeared to be growing more and more interested in the case. "They'll be back in China by tomorrow," John sighed as they entered the flat, Sherlock pulling his scarf and coat off.

"No, they won't leave without what they came for," Sherlock shook his head as he walked over to stare at the wall above the fireplace, looking at all of his notes.

"Sherlock's right," Tyler nodded, moving to stand beside Sherlock so she could get a closer look at the notes and photographs to, "They're not going to just leave London without this item, too much money's involved to do that. No, we need to try and find wherever they're hideout or some rendezvous is."

"Somewhere in this message it must tell us," Sherlock commented, talking more to himself as he leaned closer to one of the photos and ran a hand over it, staring the symbols.

Sarah, having stood back and watched while John, Tyler, Clara, and Sherlock as they focused their attention on the pictures, shifted awkwardly as she realized that perhaps she should just let them get on with it, "Well, I think, maybe, I should leave you to it..." she trailed off as John and Sherlock both started taking at once.

"No, no," John quickly shook his head, "You don't have to go yet..." he looked to Sherlock, "Does she, Sherlock?" and turned back to Sarah, "Stay a bit."

While Sherlock said at exact the same time, "Yes, it would be better to study if you left now," he gave Sarah a pointed look as John threw him an irritated glare.

"That might be a good idea, we're actually quite busy," Tyler agreed with Sherlock, getting a confused look from the other three.

"Don't listen to them," Clara cleared her throat, throwing both boys and Tyler looks before giving the other woman a polite smile, that seemed more like a grimace. "They're just joking. They always do that," she coughed slightly as she noticed Sherlock's eyes narrow at her, quickly going on, "But you're welcome to stay, if you want. I'm sure John would like that," she glanced at him.

"Yes, please stay," John nodded, smiling at Sarah.

Sarah smiled nervously back, glancing at Sherlock, who had already turned his attention back to the photographs, and turned back to John, "Is it just me, or is anyone else starving?" she asked.

"Oh God," Sherlock groaned, closing his eyes, almost looking as if he was in pain.

"Sherlock," Clara frowned at him.

"Ah, I'll go and check the fridge," John said hastily as he quickly retreated into the kitchen, not wanting to get involved in another one of Clara and Sherlock's many arguments when it came to Sherlock's lack of social graces.

Sherlock rolled his eyes and sat down at the table, scattering the photos and notes on the ciphers as he tried searching through them for any more clues, while Tyler took a seat beside him and started trying to help. Clara stayed by the wall, jumping up on the couch to move pictures around as she took each one in.

"So..." Sarah began, looking around the room, "This is what you do," she glanced at Sherlock and the girls, "You three and John. You solve puzzles for a living".

Sherlock paused in his search, "Consulting detective," he corrected, clearly growing more and more irritated.

"Oh," Sarah nodded, not really understanding as she moved to look over Tyler's shoulder to see the photos herself, frowning slightly as she looked at a photo in one of the evidence bags, "What are those squiggles?" she pointed at the markings.

"They're numbers," Tyler explained to her, seeing Sherlock's look that he sent her at preventing him from being able to think properly, "Numbers that are written in an ancient Chines dialect."

"Oh, right," she nodded again with a slightly sarcastic tone in her voice as she shot a look at Sherlock, Clara hid her smile as she noted that the other women appeared to be trying to annoy Sherlock and Tyler as a way of payback for the way they treated her earlier, "Yeah, well, of course I should have known that," she picked up one of the pictures and pulled it out of the bag to look closer at it as Sherlock sent her a murderous glare, looking furious as he tuned his head away at Clara's warning look, "So... these numbers... it's a cipher".

"Exactly," Sherlock replied tightly.

"And each pair of numbers is a word," she continued.

Sherlock and Tyler's heads snapped around to look at her, "How did you know?" They asked her.

"Well, two words have already been translated, here," Sarah shrugged, placing the picture in front of them and pointed to where there were words written under the first two numbers, just underneath.

Sherlock grabbed the pictures, staring at it transfixed, "John," he called over his shoulder, not looking away from the photo. "Clara."

"Hmm?" John looked up from where he was standing by the kitchen table, fiddling with something. Clara jumped off the couch and came over to peer over Sherlock's shoulder.

"You're going to want to see this," Tyler told him as they stood from the table, still staring at the picture as John stopped what he was doing and joined them.

"Soo Lin at the museum," Sherlock started explaining as he tore the seal on the evidence bag open and pulled the picture out, "She started to translate the code for us. We didn't see it!" he pointed to were, in fine pen, words were written, "'Nine mill...'" he read out.

John leaned in closer, squinting closer at the picture, "Does that mean 'million?'"

"Yes, but for what?" Clara frowned, looking thoughtful, "Nine million pounds, but what for? It doesn't say."

"We need to know the end of that sentence," Sherlock nodded, standing up and grabbing his coat and scarf, pulling them back on as he headed towards the door, "Come along, Tyler."

"Where are you going?" John asked them, watching them.

"To the museum, to the restoration room," he replied, glancing back at him, "We must have been staring right at it!"

"At what?" John frowned, looking confused as he stared after them.

"It's the book, Johnny," Tyler told him, turning back to look at him from the doorway, "That's what we need, the book. The key to cracking the cipher!" she glanced at Sherlock to see him nodding along with her, "That's what Soo Lin used to crack it back at the museum."

"Whilst we were running round the galleries, she started to translate the code," Sherlock continued, "That book is in her office!" and with that, he and Tyler turned and ran down the stairs and out of 221B and out to the crowed street, "Taxi!" he shouted, trying to hail a cab as he ran passed a couple of tourists, causing them to drop their map.

"Sherlock, wait," She jogged to keep up with his fast strides.

Sherlock didn't bother to reply to that, either that or he simply ignored her, which seemed likely as he rushed back over to the couple as the man started shouting at them angrily in German, "Hey, du!" he continued shouting, waving his hand around at Sherlock, "Siehst du nicht wo du highehst?"

Tyler blinked in surprise as Sherlock quickly picked up the map and passing it back to the couple before saying in fluent German, "Entschuldigen Sie, bitte."

The man snatched the map back, glaring at Sherlock, "Ja, danke!" he turned away and put his arm around the woman beside him, still muttering angrily, "Und dann sagen die, dass die Englander holflich sind!"

"You know how to speak German?" Tyler stared at Sherlock in surprise as he turned back to the curb and attempted to hail down another cab.

"You're surprised," he stated, frowning in frustration as all of the cabs that passed were either full or ignored him.

"Just a little," she nodded slowly, watching him pace a short distance up the street before turning back around, giving him a small frown as she noticed that his eyes focused on something behind her, "Sherlock..." she glanced behind her and her eyes widened as she caught sight of a Japanese couple standing a little way up the street behind her, reading the same map as the German couple, "Oh!" she gasped as it suddenly hit her.

Back at the museum, Soo Lin had the same map sitting on her desk, and there had also been one in both Van Coon's, and Lukis's flat as well when they had gone to investigate them. It was right there the entire time, staring them in the face, and they still hadn't seen it.

"A book that everybody would own," Sherlock and Tyler both said in unison as they looked at each other, both suddenly growing excited with the discovery as they started running down the street after the German couple.

"Please, wait!" He called after them urgently, making them pause and look back at them as if they had gone insane, frowning, "Bitte!"

"Was wollt er?" the man frowned in confusion as them, mainly looking at Sherlock as he glanced at his partner, just as the detectives reached them, "Was will er?"

Not pausing to reply back to whatever it was that the man had said, Sherlock snatched the map out of his hands, ignoring his outcry of clear annoyance as he looked down at the book's cover, "Hey, du!" the man shouted, "Was macht du?"

Sherlock, growing frustrated turned back, and snapped, "Minute!" before turning away and flickering through the book as Tyler looked from Sherlock to the German man, slightly concerned that Sherlock was going to end up getting punched from the clearly angry tones in the German man's voice, but she quickly shook her head and focused her attention on looking at what Sherlock was doing.

The man shouted something again in German, but Sherlock ignored him, and a moment later the man and woman walked away while Sherlock flickered through the pages of the book, "Page fifteen," he muttered to himself, finding the right page, "Entry one. Page fifteen, entry one..." he trailed off as he suddenly looked up at Tyler, realization dawning on his face, "Dead man..."

"Dead man?" Tyler repeated slowly before her eyes lit up as she worked it out, "So... they were threatening to kill them? That was what the first cipher said, the one from the bank, that library shelf, and that statue was all about, right?"

"Exactly," Sherlock nodded, reaching inside his pocket and quickly pulling the photograph of the brick wall that Clara had taken early while down at the train tracks, along with a pen, and started deciphering the code, "Thirty seven, nine, thirty seven, nine..." he muttered more to himself then to Tyler while scribbling it down on the photo, "For... nine million... for..." he continued muttering, flicking the pages as he searched, "Jade..." he jotted it down, "Jade..." he flicked the pages again, writing something down before reading everything that he had deciphered out loud to Tyler, "'Nine million for jade pin dragon den black...'" he raised his head to look at the blonde, "'...tramway'".

"That's the meeting place, then," Tyler said as she smiled at him, "Sherlock, you brilliant, brilliant man! You've done it; you've actually managed to crack the code!"

"Of course," he replied, sounding somewhat smug before he shook his head and grabbed her hand, "We need to get back to the flat and tell John and Clara."

They quickly ran back down the street towards the flat and back inside, heading upstairs, "John!" Sherlock shouted urgently, "Clara! I've got it!" They reached the landing and hurried inside the kitchen, only to find it completely empty, John and Clara no were in sight, neither was Sarah. "The cipher! The book! It's the London A to Z that they're using..."

"Clara?" Tyler looked around confused. "Maybe... they've decided to go out," she suggested, even though she didn't quite think so herself as she turned around and she felt her mouth go dry, "Oh, my... Sherlock!"

Sherlock glanced towards her sharply before following her line of sight, his own eyes widening in horror as he caught sight of the front windows in the living room, covered in yellow painted cipher that they both now recognized as translating to: 'Dead man'.

"The tramway!" Sherlock said loudly, snapping out of his trans as he rushed over to the bookcase, grabbing a copy of the A to Z maps book and hurried over to the table, ignoring the piles of stuff stacked all over it as he laid the map on top of it and began searching for the place.

"While you do that, I'll call Dimmock," Tyler told him as she grabbed her phone and quickly started calling him, "Ah, yes, good you answered," she breathed a sigh of relief when he picked up and quickly started to explain to him everything before giving the addresses that Sherlock managed to find, following after him back out of the flat, "...yes, backup would be advisable. Thank you!"

"They won't make it in time," Sherlock commented, running a hand through his hair as he climbed into the back of the cab that they had finally been able to hail down just as Tyler put her phone back inside her coat pocket.

"Yes, but we should," she said, nodding slowly before casting him a curious look over to him from where he was staring outside his window. From the look that she could see from the side of his face, she was surprised she couldn't hear his thoughts racing around inside his head, "And, just to be sure, what exactly do you plan to do once we arrive?"

Sherlock glanced back at her, his icy blue eyes meeting her own bright Hazel ones as he smirked slyly, "Make an entrance."
