"Okay we are on the way." Sherlock said over his phone and he hangs up. "Wait, where are you going?" You asked him, as you feed Victor his bottle. "Molly has completed her analysis of the kidnapper's memory card." He replied. You smile and said. "Really? That's great!"

"This shouldn't take too long, hopefully, so we can take Victor with us." Sherlock said. You nod and head up stairs and got a body baby carrier, kinda like the one John's got. You put it on and place Victor inside of it and head downstairs and the two of you head over to Bart's.

"I've taken a look at this card. There are traces inside the case of two chemicals--a marine diesel additive and a rust treatment used in ships. And apple juice, but that might have been from my lunch. So it looks like your kidnapper could be on a boat or in a dockyard." Molly explained after you, carrying Victor, and Sherlock show up at Bart's.

"Well, that's some help." Sherlock remarked. "Thank you so much, Molly." You said with a smile. "My pleasure." She said as she hands the card back to you two. You and Sherlock walk outside as Sherlock says. "We know the kidnapper is in London--close enough to leave bottles of poison around town."  

"But that still leaves hundreds of possible dock yards and boats." You said as the two of you walk down the street. "Hmmm....we should listen to that voice message again. Perhaps there's something in it to help us narrow down his location." He said.

You nod and pull out your phone and placed the card in it and pulled up the audio message. You hold up your phone to both yours and Sherlock's ear as you listen to the message.

"Wait, right there! There's something in the background. Do you think you can filter it?" Sherlock asked you. "No problem." You said and you filter out the kidnapper's voice and you hear two rings of a church bell.

"The sound of church bells. Ah, a campanological clue." Sherlock replied and pulls out his phone, looking up information. "I've looked for dock yards that are close enough to church's and there are three possible locations." He said. "Okay, good. So where do we go first?" You asked him.

"Our first stop is in Chelsea: Battersea Bridge." He replied as he flags down a cab and you climb in.

You make it over to Battersea Bridge and listen to the bells over there. And to be honest, the bells sounded very similar to the bells you heard in the audio. "That sounds like a match to me." You said. "I agree but there might be other church bells out there that sound the same. Let's go to Vauxhall, near Nine Elms Lane." Sherlock said and you two head out again to Vauxhall.

Once you arrive you there you listen to the bells but they sounded nothing like the one in the recording, there were three rings and it sounded deeper than the one in the audio. "This isn't the church we're looking for." You said as you wave your right hand around.

Sherlock shakes his head and said. "Battersea Bridge location still looks the favorite--but let's check the docks by East Smithfield."  

"Okay where is that?" You asked him, as you stroke Victor's hair. "All the way east, just north of the river." He replied and the two of you head out. You arrive at East Smithfield and found that the bells there sounded similar to the ones in the audio as well.

"So we have two potential locations...." Sherlock said then he pulls out his phone.

"What are you doing?" You asked him. "Calling John. I'll have him keep an eye on Battersea Bridge." He replied and John answers. He agrees to go once he finds someone to watch Rosie.

"Right, now, we have two areas to investigate without tipping off the kidnapper." Sherlock said as he pulls out his mobile and starts to tap away.  

"The police have helicopters with infrared cameras that can be useful for this kind of thing." You said as you look up at him and place your arms around Victor. "But they can be noisy and, as luck would have it, Mycroft runs a surveillance satellite that can do the job silently for us." He replied. "Of course he does." You muttered.

"He doesn't like the British people to know about it so he won't kick up a fuss if we hijack it for a few minutes." He continued as he continues to type on his phone. "Is that what your doing? Hijacking one of your brother's special toys?" You asked, teasingly. He smirks at you as he continues to type.

"Ah-ha! I'm in! Now I just take a thermal image of both Battersea Bridge and here and I should be able to figure out where the kidnapper is." Sherlock said as he works on his phone some more.

"Hmm this image shows three lonely people sitting on their own in three dockyard units. I'd suggest they're either sitting at a desk or tied to a chair. I've looked up the tenants of each unit and it's been very enlightening." He said, with a smile. "Yes that's all good and all but where is the kidnapper?"  

"Orchard Fruits LTD. It's the only place to likely have apple juice but then again that could have come from Molly's lunch but she's Taryn a source of cross-contamination. I'll text John, since he's nearby, and give him the news. Afterwhile Sherlock's phone goes off and he sees he has a video call from John.

He answers and on his screen you see John's face. "You were right. This is where they are." He said. "Good." Sherlock said. "The police are here now, and we're just...." John started to say but then you hear gunshots in the background.

John looks behind him and he starts to take off. "John! John, what happened?" You asked as all you could see was John's running feet.

"Let me through! I'm a doctor!" John shouts and you see him place the phone down as you and Sherlock watch John giving CPR to someone but it seems to have failed as you see him stop then he looks over at someone off screen and shakes his head.

"No, no good." He said and the call ends, abruptly. 

You place your hand over your mouth as you look over at Sherlock. "Please tell me that wasn't my aunt that got shot, Sherlock." You said, tearfully. "I don't know, love. Let's head over there and see what we can find." He said and the two of you head off.
