Author's Note: Stacy suggested Gwen helping Arthur get into a nightclub to do an investigation, and larasmith mentioned Gwen being an informer.

One of the Guys

Arthur and Merlin stood inside the taped off alleyway studying the body as the forensic photographer took pictures. The call came in early in the morning from a baker who was greeted by the unsavory sight.

The flash lit up the exposed skull and brain from the fatal blow and Merlin turned away. Arthur snickered. "Seriously? You've seen worse than this."

Merlin tried to look again and grimaced. "There's just something about brain matter…"

Arthur rolled his eyes. "Stand on the other side then."

As Merlin rounded the body, he spotted something on the stiff's hand. He crouched down to get a better look. "What's that?"

"What's what?" Arthur and Gilli, the photographer, leaned in to look. Merlin took out his pen and used it as a pointer. He traced the outline of faded ink on the pale hand.

Gilli took a close-up shot. "That looks like a stamp from the Crystal Club." Arthur and Merlin gave him a blank look. "It's the most popular club in London."

"And you know that how?"

"I do have a life!"

They didn't quite believe Gilli and studied him with furrow brows until Merlin's phone rang. "Emrys," he answered. "Another one?" Merlin glanced at the body. "There wouldn't happen to be a club stamp on one of his hands, would there?" There was a moment of silence, and Arthur gave him an expectant look. Merlin gave a thumbs up. "Great! I mean not great as in great, I mean…you know what I mean. Thanks Leon." He hung up.

"Where was the body found?" Arthur asked.

"A few block from here."

"Okay," Arthur said waving in the coroner. "Let's get him bagged. Gilli, tell us everything you know about this club."

Gilli had actually only been to the club once for his college roommate's cousin's bachelor party. He described it as one of those really expensive clubs you see in movies. It was a converted warehouse glammed up to the nines. The drinks cost more than your hourly pay, every chair you sit on cost more than your rent, and the girls dancing in cages and swinging on aerial silk swings are dressed in those really expensive, blinged-out Victoria's Secret bras. "How do you know its Victoria's Secret?" "What? I'm a warm blooded male. I've seen the shows on the telly." Gilli's point, the moment you step in, you feel like you're sinning.

Doing more research on the club they discovered the owner served a bit of time himself, but they still didn't have enough evidence to move forward. The bodies were identified as repeat offenders. They just had to find evidence of a link between the two.

This led to a good old fashioned stakeout. The problem with tailing club owners is that they don't get out of work until early morning. The sun was rising and the light hit Arthur right in the eye. He flipped down the visor in annoyance and rubbed his eye.

"Isn't it romantic?" Merlin said, sipping his coffee.

"Shut up, Merlin."

"Speaking of romance," Merlin continued anyways, "I was talking to your sister the other day and—"

"Why would you subject yourself to mindless chatter with Morgana?" If they were going to talk about his sister, Arthur was definitely going to develop a migraine.

"As I was saying, I was having a lovely chat with her, and she said that you and Mithian were on again. When did this happen?"

Mithian, his on and off girlfriend, had called him a few days ago. They had a friendly dinner and decided to give it another go. "Stop gossiping with my sister. What would Freya think?"

"Hey, at least I know where I stand with my girlfriend."

Almost an hour later, there was movement. Alvarr, the owner, and some others exited the club. Arthur snapped photos of their every move until they got into their cars and drove away. At the station, they set up a board with all the pictures pinned to it. All the men in the photos were identified; their mug shots circled around Alvarr's and the two bodies with red strings linking them all together. But they still couldn't pin the murderer or even find a motive.

They needed a new plan.

The force stood around the phone listening to Gwaine as he made his report. "There's no way I can get in."

Arthur stared at the phone in disbelief. "Are you kidding me? You can't get into a club? You're… you!"

"Their security is tight and not easily persuaded," Gwaine's normally charismatic voice sounded defeated through the speaker. "I tried everything. Wait, no. I should've flirted."

Gaius crossed his arms and looked around. "Any ideas?"

"Maybe Gwaine should try again, this time in a dress," Percival said.

"A little black dress," Leon added.

"Aw man," Gwaine said. "I didn't shave my legs."

"You could wear tights," Merlin suggested.

Arthur shook his head and turned back to the board. Alvarr had dealings in drugs, and his club was undoubtedly run on drug money. If the murders were drug related and with the amount of security Alvarr had set up, he wasn't the one to get his hands dirty. So who did it? Arthur followed the red string to another mug shot. Between the two was one of the photos he snapped of Alvarr interacting with another man. Cenred Essetir, Arthur read. "Cenred, Cenred…Why does that name sound familiar?"

Merlin, too, looked at the picture. "Cenred Essetir, let's see." Merlin pulled out the file. "Here we are. Cenred Essetir: drugs, fraud trafficking, thef—"

"Trafficking?" Arthur interrupted.

"Yeah."

A light bulb went off in his head. The list Gwen gave him what seemed like ages ago. "We might have a way in," he said grabbing his own phone.

Over the other, Gwaine's voice came through again. "What? What's happening?"

Gwen and Tiny were on the couch watching Antiques Roadshow. Well, it was more of Gwen watching and Tiny resting with his head on her lap. She was playing along, and right when the price was about to be revealed her phone rang. She reached over for it, and Tiny made a little disgruntled noise but didn't make an effort to move. She didn't have a chance to say hello when Arthur started speaking.

"Do you know an Alvarr Neahtid?" Arthur asked with haste.

"Hello to you, too, detective."

"Alvarr Neahtid. Do you know him?" he asked again tightly.

"I do…" she said.

"Do you know of his club? Can you get me into it?"

Gwen shifted uncomfortably and Tiny moved away with a concerned look. "Yes and yes," she said. "What is this about?"

"Good. I'll pick you up in a half hour."

"Are you saying what I think you're saying? Because if it is, I'm going to need more than a half hour."

"Half hour." Arthur hung up.

Gwen sighed and looked down at Tiny. "Not even a please."

Arthur probably didn't need to bang on the door as hard as he did, but he was getting anxious. He heard Tiny's muffled bark from inside. The door swung open, and Gwen was already coming out with one shoe on and the other in her hand.

She closed the door behind her and supported herself on Arthur's shoulder to put on the other shoe. "Do you know how hard it is to get ready for a place like the Crystal Club in half an hour," she said practically out of breath. After she balanced herself, she got to walking down to the car. Arthur got a good look at her. She finally looked like the femme fatale he often envisioned her as in her little black dress. She stopped and turned to face him. He noticed a bit too slow. "Were you checking me out?" She did a little twirl. "You can't see my gun, can you?"

"W-what?" Arthur choked out.

"Just kidding. My weapon of choice is a fireplace poker." She noted his confused look. "It's a long story."

A block away from the club, they pulled up behind a van. The back opened to reveal two technicians and an interior full of gadgets. "George, Elena, this is Guinevere. Get her wired." Arthur helped Gwen into the van, and once she was in Elena pushed George out.

"For propriety," she said, and closed the van door.

A few minutes later, Arthur jumped when he heard Gwen's voice in his ear. "This is exciting!" Arthur huffed. "Don't get too comfortable," he muttered back.

The door opened and Gwen stepped effortlessly down from the van, like a gazelle in heels, and straightened her skirt. No trace of a wire could be seen under her tight dress.

"I'm patching you guys through to everyone," Elena said. "Good luck."

Arthur and Gwen hopped back in the car and drove up to the front of the club. "So I'm the best you got?" Gwen poked her fingers back and forth at him. "Does this make me part of the team, just like one of the guys?"

Gwaine laughed in their ears. "I'm not complaining."

"Don't encourage her," Arthur said to Gwaine.

They got out of the car and Arthur handed his keys to the valet. Gwen looped her arm in his and they went straight to the front door, cutting the queue and sparking vocal protest.

The bouncer looked at them smugly, prepared to reject them. "Mayard," Gwen said.

"'scuse me?" the bouncer scoffed.

"Oh," Gwen tilted her head. "You must be new."

"Back of the line lady, and take your boytoy with you."

"Look at your list, you idiot," Arthur snapped.

"You won't have to look too hard. I promise it's at the top," Gwen said more politely.

The bouncer looked down. Indeed Mayard was at the top. He let them through.

They were greeted with thumping music and flashing lights. It was everything Gilli described and more. Elaborate crystal chandeliers hung from the ceiling. Lights refracted off crystal accents all around the room making it glitter. "Dance with me, detective," Gwen said dragging him to the dance floor. She pulled him close, forcing him to move with her to the music. "Alvarr's going to be told that we're here. The bouncer's new so he won't know that you're not Helios. Alvarr's always at the VIP section, I'll distract him there and you do whatever it is you need to do."

They got a clear view of the VIP section, and Alvarr sitting in the middle of a gaggle of women. "Are you ready?" Gwen asked Arthur.

"I should be asking you that," he replied.

Gwen gave him a confident smile and pulled away from him. She disappeared into the crowed before reappearing on the steps that led to up to the VIP platform.

The guard let her through, and the plan was in action. Alvarr stood to greet her. Arthur saw their mouths move and heard them loud and clear.

"It's a pleasure to see you again, Alvarr."

"And you, Gwen. Where's Helios?"

"Who said I was here with him?"

"That's not what I mean. Word on the street has it he's pulled a runner."

"Is that the only word?"

"Where is he, Gwen?"

"Gone."

"Where?"

"To Hell, I imagine."

"Now he's left you to clean up his mess, I see."

Gwen's snort was small and only heard by Arthur in his earpiece. While they chatted, he found one of the doors that led to the basement where Gwen said all their dealings occur. The door could only be opened with a keycard. He stayed in the shadows and notified the others. "Looks like you get to knock down another door, Percival."

"Ready when you are, boss," Percival responded.

"You didn't come alone."

Arthur pushed back deeper into the shadows and waited.

"I brought along a friend."

"Why don't you bring her up to join us?"

"I don't think he's your type."

"He? Moved on from Helios that quickly?"

"A girl gets lonely."

"If you need someone to keep you company you can always—AH-OW—Okay I get it."

"The club is still going strong, I see."

"We're literally sitting on gold."

"White powdery gold?"

"Party upstairs, business downstairs."

In his ear, Merlin said, "The alley is clear. We'll come in from the back. Percival and his team will come through the front and go to you."

"Have any trouble lately?"

"A couple amateurs blew a run a while back. Cenred put them down though."

"Down as in…dead?" Gwen whispered.

"Very."

"Well that's quite the lesson. Is Cenred here? I bet he has a few words to say to me."

Alvarr chuckled. "He's downstairs."

"Let's go then."

"It's your funeral."

The curtains covering the back wall of the VIP lounge hid another door to the basement. "Don't get yourself killed, Guinevere." She made a little hmph.

"What is she doing here?!" Arthur winced at Cenred's gravely tone in his ear.

"Hello, Cenred. Where's that wife of yours. I was hoping we could start Real Housewives of the London Underground."

"Where's Helios? Where's my money?"

"You're sitting on a pile of drugs and you're concerned about money?"

"He owes me."

"It's the principal, isn't it?" Gwen laughed. "Well, good luck finding him."

There was a crashing sound, a table being flipped maybe. "Oh, come on Cenred there's no need for that," Alvarr said.

"Tell me where the fuck he is!" There was a shuffling sound, and then Gwen made a choking noise. "Tell me where he is, you bitch, or you'll be in my next shipment!"

"Move in now!" Arthur ordered. He heard the sound of Merlin confirming the command and another door being busted through. Behind him, clubgoers screamed as the reinforcements worked through the crowd. They busted through the door and Arthur led them down the stairs.

Merlin's group got there first, guns trained on the goons. Only Gwen and Alvarr had their hands raised.

"It's over Cenred, Alvarr. You're surrounded," Arthur said. Some of the goons dropped their weapons seeing that the fight wasn't worth it.

"I have no idea what's happening," Alvarr tried to play innocent with his hands up in the air in surrender.

From behind, Percival disarmed Cenred. It distracted the others, and they too were disarmed and cuffed. To keep up appearances, Gwen was cuffed as well by Gwaine. He must've said something cheeky because she was biting back a smirk. The grunts were loaded into vans and Cenred, Alvarr, and Gwen were placed in separate cruisers.

On his way to the front of the club, Arthur went over to Leon doing crowd control. "Everything's fine," Leon said. "It's just everyone trying to get their cars. The valets ran off."

Arthur nodded. "We'll get some more hands to help out. Gotta get my car, too." He then went over to the cruisers that held Cenred and Alvarr and the others. He told them to head down to the station.

Gwaine was standing outside his car waiting for Arthur. "A drug bust and a murder solved in one night. Can we keep her?" Gwaine said opening the door and helping Gwen out.

Gwen rubbed her wrist when he uncuffed her. "So did I do good, or did I do good?"

Arthur frowned. "Did Cenred hurt you?"

Gwen's hand automatically went to her neck. She rubbed the side as if she meant to do it. "Pfft. Cenred couldn't hurt a fly," she brushed it off. "Take me home, detective. My feet are killing me."

A/N: Please don't kill me for giving Arthur a girlfriend! I have my reasons which will be revealed in the next chapter. Or now seeing how I can't keep a secret. Can you say jealous Gwen? Hahaha

Thanks always for reading and reviewing!
