You double checked the contents of your pack. The Enterprise was orbiting a leisure class planet and everyone was getting a rotation of shore leave. You were in A group and it was almost time to beam down to the planet. 

Unlike most of your co-workers, your time on the planet wasn't entirely your own. You had a mission to complete. While you were technically a part of the security team, you actually worked directly for Star Fleet. Your specialty was assassinations though you'd done everything from organizing coups to stealing priceless artifacts. 

Reassured that you had everything you needed for this assignment, you grabbed your bag and headed for the transporter room. You stepped up on the platform as you waited for others in your group to arrive. You stood straighter as several of the bridge crew walked into the room, including Spock and Kirk.

Jim ran his eyes over you as he saw you. You resisted the urge to roll your eyes. Due to the nature of your assignment, you were wearing tight black leather pants and a black top with cutouts that hung lopsided on your shoulders. Rhinestones enhanced the design on it. You'd also put up your hair and done your makeup, neither of which you usually bothered with. 

"Well, hello y/n," Kirk said with a smirk. "You look...different."

You arch a brow at the back of his head as he takes the spot in front of you. "Captain, Commander," you said by way of greeting the two men. 

Spock nodded his head once in acknowledgement. "Lieutenant Y/L/N."

Once you were on the surface, Kirk had tried to get you to accompany them to wherever they were heading, but you expertly extricated yourself. Your target was too important. Genis Hardover was a serial killer. As he hopped from planet to planet, he was near impossible to track and find. Intel put him on this leisure planet. He had been tried for several of the murders in his absence and you were to carry out the sentence. 

Nightclubs were Hardover's preferred hunting grounds and you had narrowed the options down to two. You headed to the most likely of the choices and settled yourself at a seat at the bar. The mirror reflected most of the club behind you so you could observe without appearing to do so. 

You'd been at the club for hours and had nearly given up when you saw him. Your target just walked into the bar accompanied by none other than Kirk and Spock. Fantastic. You clenched your teeth and the muscle in your jaw twitched. He'd picked at least one of your crew mates as his next target. 

You kept your gaze locked on him in the mirror as you debated what to do. Luck was with you as he approached the bar and happened to stand right beside you. You listened as he ordered drinks for the table. "That's a lot of drinks for one man," you said. You smiled and gazed at him through your eyelashes. 

He leaned on the bar and flashed you smile. "Here with some friends. Where are your friends, pretty lady?"

You shrug. "I was supposed to meet them but I think I may have gotten the wrong place."

His eyes ran over you from head to toe as the bartender returned with his drinks. "Well, why don't you join us?"

"That would be grand." You smiled and jumped up from your seat. "Let me get another drink."

You ordered a drink and turned toward the door as if watching for your friends. You kept an eye on your target in the mirror and grimaced when you saw him discretely drop something into the glasses. You turned when the bartender brought your drink back and grinned at him. "Let's go."

As you approached the table, Kirk was the first to see you. He frowned and glanced between you and Hardover. "My friends!" you exclaimed. You glanced at the killer beside you. "You found my friends. How did you do that?" 

He merely gave you a tight smile. You had to walk a tight line here. Hardover was smart. You didn't want him getting away because he was too suspicious. "I'll grab you a chair," he said. 

"Not necessary," Kirk said as he grasped your wrist and pulled you down onto his lap. He ran one hand through your hair and laid his mouth against your ear, making it look like he was kissing you. "What's going on, y/l/n?"

You turned your head against his. "Just go with it."

"I wouldn't have taken you for having a boyfriend the way you were acting at the bar," Hardover said, a bite in his tone as he handed out drinks. 

You forced a laugh. "Jim's just a bit a fun. He's allergic to relationships."

Kirk pinched your side hard and you grunted. You reached for your drink and pushed it over so it would appear you'd spilled it on accident. Jumping off of Kirk's lap, you scrambled for your drink managing to knock everyone else's over in the process. Your crewmates were staring at you with wide eyes. They knew there wasn't a clutzy bone in your body. Hardover was fuming. 

He grasped your wrist and pulled you toward him, ignoring Kirk's protests. "What are you playing at, little girl?"

You ran your free hand along your waist then grasped the wrist of the hand that was holding you. "Genis Hardover, an interplanetary tribunal has found you guilty in the deaths of seven men and women."

He laughed. "You're a bounty hunter? A little thing like you? Good luck with that, sweetheart."

"I'm the executioner."

His eyes went wide as he realized he couldn't breathe. You untangled yourself from his hold and glanced at the others. "Get out of here. Now."

Kirk looked like he wanted to protest. 

"I'll be out in a moment. Go." They followed your orders this time. You watched until they were clear. "Someone help. He's not breathing," you yelled in your best panicky voice. "Help please."

You lowered Hardover to the ground, knowing he was already dead. As a crowd gathered around him you moved backward until you were lost in the group, then you made for the exit. 

Kirk and Spock each grabbed an arm as you stepped outside. "Hello Captain, Commander."

"What the hell is going on, y/n?" Kirk snapped.

"If you would allow me, Captain," Spock interjected. "I believe that Lieutenant y/l/n may have other duties to Star Fleet besides being a security officer on the Enterprise."

"Figured that out all on your own, did you Spock?" Kirk said. 

You shrugged out of the men's grips while they were busy frowning at each other. "Could we move this conversation a little further away?" you asked. They nodded and followed you through the dark streets. 

Kirk pulled you to a stop as you came to clearing. He called the Enterprise. "Three to beam up," he said and soon you were all back on the ship. 

"Come along." You lead the men to the observation deck, sighing in relief when you found it empty. Once they were all in the room, you turned to the security panel. Punching in several commands, the observation deck locked down. No one was getting in or out without your permission. 

Along one wall was a large black cabinet. You made your way to it and began going through the many layers of security. "Wait a minute. That's yours?" Kirk said and you glanced over your shoulder to see him frowning at you.

"Yes," you answered and shot a glance at Spock.

"The Captain has attempted to open this cabinet on multiple occasions," the first officer explained. 

"Well, here you go," you said as you got through the last lock and swung the cabinet open. You dropped your bag inside and grabbed a bottle of whiskey from the bottom shelf. Kirk stepped up to examine the contents of your cabinet. Nothing inside looked overtly dangerous. You handed the bottle to Kirk and took off your belt and hung it up, leaving the thin needles concealed inside.

"Why so much security for this junk?" Kirk asked.

"It is not junk, Captain," Spock said. "A cursory observation of the contents has shown at least 37 ways to kill someone without being detected. As I am not trained in such things, I am sure I am underestimating."

You were impressed with the Vulcan's knowledge. "Very good, Commander though you are correct that you are underestimating."

Kirk dug up glasses from somewhere and poured a bit for each of you. They sat on a nearby couch and you paced the floor in front of them. Realizing what you were doing, you stopped. "Sorry. My adrenaline is up from the job. I normally workout after."

"What exactly happened tonight?" Kirk asked.

"I work for Star Fleet directly. I was assigned to the Enterprise as it was a convenient way to get around without rousing suspicion. I can't tell you everything I do, but tonight was a good example." You took a sip of your drink. "Genis Hardover was an interplanetary serial killer. His kills are estimated to be around the 70-80 mark but that's a guess. It could be more. He was sentenced to death for 7 of the murders. I was sent to execute him."

Spock frowned. "The gentleman in question did not appear to be anything but congenial."

"That's what he does. He befriends one or more victims at high tourist destinations, by the end of the evening they're...dead." Your hesitation was due to your reluctance at sharing just how Hardover killed his victims.

"Might I ask why you spilled our drinks?" Spock asked.

"He put something in them at the bar," you explained. 

"How did you kill him? I didn't see you do anything but grab his wrist," Kirk asked.

"Unless I am mistaken, I believe Lieutenant y/l/n used a micro needle to inject some sort of poison into her target," Spock said.

"Close," you told him and smiled. "Hardover is horribly allergic to shellfish. Anytime I can make it appear natural is preferable."

You glanced at Kirk who had suddenly gone quiet. His eyes were wide and it was evident his mind was elsewhere. 

"Captain?" you asked.

His gaze locked on yours. "Have you done this every time we were on shore leave?" 

Your lips twitched. "Shore leave, diplomatic missions, deliveries. Didn't you wonder about the randomness of some of your assignments?"

"Damn it," he said and smacked the seat of the couch next to him. "I won't have your actions endangering the rest of my crew," he said.

You shrug. "I won't take assignments that endanger others. I made that clear from the beginning."

Kirk sighed and he rubbed his forehead. 

"Something you should consider, Captain, is that my skills are now at your disposal as well." There were many times you could have helped with one of Kirk's schemes but you had to remain quiet to avoid exposing yourself.

He brightened at that. "Very well, y/n. And we will offer you what aid we can."

You glanced to Spock. "In that case...Commander, I was hoping you could demonstrate the Vulcan nerve pinch for me. I believe it would prove useful."

"I am not sure it is logical to show you more ways to injure someone," Spock said with an arch of his brow.

"I am certain that I know enough, you showing me one more won't matter much," you retorted. 

"Point taken, Lieutenant," Spock said, a small smile flashing briefly on his lips. "When shall we begin?"
