"Ready to get your hands dirty?" Murphy comes over to me later that next day.

I eye him standing up from my desk. I felt good when my lieutenant took my idea of him going under cover in the cell the get more or of flash, so of course I was eager to see what today held. "What do you have in mind?"

"Undercover. You''ll be my wife, Mrs. Jeffries."

"Let's do it." I say the same words he said the night before "what are we going after?" I ask.

He and Olivia explain to the rest of us how we are going to go undercover to go after a man who claims his viscous awful writings of murdering a child are just fantasy. The man has an art gallery tonight in Manhattan, we need to move fast to make sure we get him before another boy is hurt. I get dolled up in a white dress and put my hair into a slick ponytail. We get wired and head off into the gallery. We walk the pictures, all black and white, all of little children. We see the women close near us so we begin to play our parts further "Oh, honey, I love this one. This is my favorite in the whole show." I ooze to him, like I've never seen anything so gorgeous before.

"It is striking." A women comes over to us.

"Is this your gallery?" My fake husband asks her.

"No, the photographer's my husband." She smiles back.

He puts on a shocked face, "you're married to Simon Wilkes? Is he here? I'd love to meet him."

"Oh, that's great. He's right over there." She points to her husband, about ready to move over towards him to introduce us.

Declan gives me a little squeeze so I ask the wife "you know what, do you have a catalog I can look at?" I ask her, wanting to let them be left alone.

I raise my eyebrows with a big smile towards my fake husband and he tells me "whatever you want, baby, just get a price."

"This way." His wife takes me to the side and Declan moves towards Simon, I spend the rest of the evening talking with his wife about photography that is over rated and over priced.

The next day Declan plays the recording he got of him and Simon in the bar talking about a plan to the ADA Barba "that's it?" He asks once it's over "sounds to me like you're flirting with entrapment." Barba turns his attention to Murphy "you brought up procuring a boy."

"He didn't shy away." Murphy reminds him. "He was the one that brought up using boys for more than just sex." Murphy turns to me "did you get anywhere with the wife?"

I shake my head "big blind spot, she adores him."

"She's a sicko too." Finns chimes in.

"Tell me that at least Wilkes has a record?" Barba asks.

"He stays under the radar." Olivia tells him.

"Except when he chats about boys in the school yard he wants to torture." Amaro adds on.

"We do not indict people for just imagining things." Barba reminds everyone in front of him. " Show me a substantial step, we'll have a different conversation." He goes to walk away but stops before he turns fully "Nice to meet you Ms. Grey, I've met your father, brilliant man." He gives me a firm head nod then leaves the room.

"Lawyers think too much." Murphy says once he's gone. "This Wilkes is bad news. Go back to Gordon. Get us something more."

Later that night I get a text with an address from Benson. I take a taxi over there and am met with multiple cop cars lit up and officers and detective moving in and out of the building. I flash my badge to the man at the door and quickly meet everyone inside. "What the hell is this place?" I ask once through a regular looking room and then in a makeshift torture chamber like one.

"Pull up the floors. Knock out the walls." Murphy directs the men and women collecting evidence.

"This place is pristine." I say followed by a whistle.

Amanda asks "He brought boys here?"

Murphy explains "so he scrubbed it clean. He's careful."

Amanda asks, leaning down resting on her knee's over a drain "so what does he do with the bodies?"

"Open up the drains and test for chemicals." Murphy makes another demand. "I want a drop of blood, a shard of bone, something, anything."

"Lieutenant, counselor, detectives" Finn calls out to all of us "CSU found these hiding behind a fake wall."

Armaro mumbles under his breathe "sick son of a bitch."

Murphy "Benson, Rollins, get back to the station and interview Simon! I want him sweating!" He tells them and Rollins quickly exits the room behind Benson to get moving on the interrogation. "Finn and Grey, stay here and wait for CSU to finish, then follow them to the lab and wait for the results. I want to be called the instant they are in."

"Got it." I say back, putting gloves on my hand to help look around for evidence.

It takes hours for the different teams to collect everything they needed. Finn and I try to stay out of the way and talk through different scenarios of way he could have gotten away with it for so long or how many possible victims there could have been. "Finn, we're done here. We'll be heading back to the lab now." A women in a big navy jacket tells him and Nick nods to her, turning back to me "let's go." He says and I follow him into the street. The sky is still dark, filled with clouds and I get into the passenger side of the black car as he drives behind the van to the lab.

"Gonna take a few days to get the evidence back." Finn calls Murphy to tell him what the women from the lab said once we are inside. "Yea, sure. You got it." He says to the other side and hangs up.

"He always so chatty?" I ask, clearly understanding how frustrated Declan must be about this situation.

"He's a tough guy, catches a lot of bad dudes. This guy is sick, it's tough seeing these people get away with it." He tells me.

We get into the car and as he pulls off towards the station I ask him "does it happen a lot, people getting away with this stuff?" He eyes me as if I that's a weird a question to ask. I shrug and explain to him "my dad's in the FBI. There's only been a few cases he's been on that they've haven't been able to catch and put away."

"There's a few here and there. Some worse then others." He explains with few words. We don't say anything more as we drive to the station. When we get there we are informed that Simon had retained a lawyer and we can no longer talk to him without her there. The next day goes by an arraignment hearing is set up for the next morning. He is charged with attempting kidnapping and attempted sexual abuse of a child. "As soon as I know, you'll know." Murphy hangs up the phone "That was Barba. Good news, Wilkes has been remanded and slated for a psych eval. Bad News: it's a tough to try a case with no victims." He says to all of us. "Where are we?"

"I got more bad news." Finn speaks up. "Just got off the phone with taru, Wilkes was telling the truth about those torture pictures. Photoshopped."

"I might have something." Nick comes over to us. " There was a nine-year-old from P.S. 27 who went missing last year."

"That's the special needs boy." Olivia adds on.

Nick nods "he turned up six days later, couldn't tell the police where he'd been."

Murphy directs us "show the family Wilkes' photo. Go back to the school. See if anyone has seen Wilkes with kids, and while you're at it, check out any open molestation cases."

We all move, and Amanda and I take to the school the boy used to attend to. We show the photo of Simon to teachers, students and parents but no one recognizes him. "It's like he's a friggen ghost." I say as we question another parent about him.

"Men like this blend in, they don't stay out in any particular way." She explain as she holds the photo up to another women with a child. "Do you recognize this man?" She asks.

The women barely looks at it and says no before shuffling away from us. "People always this scared?" I ask her.

She shrugs "they don't really want to know who this person is. They just want to keep going on with their lives." Another women picks up her child from school and Amanda asks her if she knows him.

The women shakes her head and almost moves away but stops, lowering her daughter from her hip and holding her by the hand "wait, yes. I've seen him." She says.

"Where?" I ask, hoping for some kind of information we can use to lock him up.

"He takes pictures sometimes of the kids at pick-up. I asked a friend of mine if she knew him but she didn't either. She had her husband ask him the next day who he was but he pulled out a card for his business and said he was working on a new project." She explains to us. "Is there a problem?" She asks.

"No, no problem. Thank you for your help." I say, not wanting to startle her or her daughter. She nods and walks away from us. The school day ends and we head back to the station.

Amanda and I are the last ones back and Murphy says out loud "I find myself in the terrible position of hoping we found a victim."

"That was the boy who went couldn't I.D. Wilkes." Nick explains.

"A few kids and moms at the school recognized him. He takes pictures, but he hasn't bothered anyone." I say next informing them what Amanda and I have come up with.

"What about the molestation cases?" He asks.

Olivia answers "five lineups, five strikeouts. We've checked every single file on Wilkes' computer. We've checked every single photo on his cloud account. Nothing." She stands, moving her hands across one another like we striked out.

"Go further." Murphy directs " Look into, uh, former addresses close to school yards. What do we know about his history?"

"Well, he has an ex-wife and a son living in Toronto." Olivia says to him knowing that past "They're ducking our calls.

"Hey, that was CS." Amanda comes over, just off the phone "they found body fluids, hair fibers, fingerprints all over the dungeon. They're even on the boy's clothing in the hamper."

"Good, and they're running DNA?" Murphy asks.

"Yeah, they already did that." She says back "only one hit: Wilkes."

"No trace of anyone else?" I ask.

"He must have cleaned the place up." Murphy says.

"The place isn't clean." Amanda reminds him, reminds us all "there's no sign of bleach there, and he can't just wipe up everybody else's DNA and leave his own."

"But he told us what he'd done to kids in there. I mean, why in God's name would anyone make that up?" Nick asks. We all sit there silently at his words, wondering where we go next.
