(Back in the office. Interrogations are underway. Lee is giving Anthony a break and sits with Rachel watching the split screen recordings. Rachel receives a text from Gill that reads: "Dinner at mine tonight to celebrate Sammy's arrest." Rachel begins typing a response about not being sure when she'll get off and having to get Charlotte. Before she hits send she receives another text from Gill reading "Bring Charlotte." Rachel erases most of what she typed when she receives another text. "8PM the latest. With the case closed you can leave early." Rachel looks to Lee and shakes her head. Gill knew her job better than anyone and although she's been retired for years she was still calling Rachel's shots. Rachel pushes a few strands of her dark hair back behind her ears before finally responding, "I'll see what I can do." If she was honest, something about this whole case made her want to be alone. Sammy walks into the room and presents both of his senior officers with their respective mugs. He's not getting paid for his time but he was too stubborn to go home.)

Lee: Look at that boss. He's done it without scolding his face off.

Rachel: Well done. (Smirks and sips her tea.)

Sammy: (to Lee) I could still scold yours.

Rachel: (points) Sit down before I have to scold you. (Sips tea) Again. (Sammy obediently sits. Points to screen and looks to Lee) Did I not say it was the Grandad? Day one. I said it, didn't I?

Lee: You did Sherlock.

Sammy: I still think I should be able to-

Rachel: Sammy, we are not going through this again. Keep schtum.

(Interrogation. Anna sits beside Arianna, the youngest sister who seems nervous being separated from the protective touch of her eldest sister. Denise sits beside Lexi, the oldest who sips a tea. Both girls are obviously sad but so far silent.)

Anna: (to Arianna) I know you're scared but I promise you, you won't get in any trouble for telling me the truth.

Lexi: We told you everything we know miss.

Anna: You told me everything you were told to say, Lexi. (Lexi shifts uncomfortably and sips her tea. She gives her little nervous sister a warning glare.) Trust me, it's ok to tell us the truth now. You won't be in any trouble. I know you want to do the right thing. You want to help your sister Zoe, don't you?

Lexi: We can't help her. She's gone.

Anna: But you can help her, by telling me what really happened. We can lock up whoever is responsible. You can help yourselves too. You won't be in any danger, if we're able to lock up whoever hurt Zoe. If you tell me the truth I can make sure you won't go home to a place that's unsafe. (Arianna starts crying. Denise hands her a box of tissue.) Have I said something to upset you Arianna?

Arianna: I wanted us all to be safe! Me, Zoe and Lexi. All of us!

Anna: I know. I'm sorry. The Browns were meant to keep you safe.

Arianna: But they didn't! They hurt us! They hurt all of us. Grandaddy Tim, he beat Zoe. He hided her everyday.

Lexi: Ari, stop. (Arianna stops and gives way to sobs. To Anna) How can you be sure our next family will be safe?

Anna: I'll personally make sure of it.

(In the viewing room.)

Rachel: Careful making promises.

(Interrogation.)

Lexi: Everything was fine with the Browns. Mummy Judy was actually really kind to us and Anthony, he was like our big brother, always looking out for us. But, one day, we came home from school and Mummy Judy, she looked like she'd been crying and her face it were all red and Grandad Tim were there. We never met him before that, but she said he were going to stay with us now. He hits her. He hit her and Anthony. He didn't touch us, none of us, not for awhile. But one day he sort of, he singled Zoe out. He hided her.

Anna: He hit her?

Lexi: Yes.

Arianna: Everyday!

Anna: Did he use his hands?

Lexi: His hands. His belt. His cane. Anything he could get his hands on.

Anna: And he hit her everyday?

Lexi: Yeah. Anthony always stood up for her, if he was home and then Grandad Tim chucked him out. Said it was because of the weed but it wasn't really that.

Anna: Why didn't you tell anyone? Your case worker? Or a teacher?

Lexi: Because we were scared. There's not a lot of families that will take three siblings all together. If we got taken away, we'd get split up, and if we got split up and something like this were happening to one of us, they'd be all alone. And then, what if we told, and they said we were liars? Then what? It'd only be worse at home wouldn't it? And Mummy Judy, she talked to Zoe, and Zoe was, she was the strong one. Mummy Judy told Zoe, how she saved her, how because of her, Grandad Tim started leaving her alone and then she could be a better Mum to us.

(Viewing room.)

Sammy: So, she was a sacrifice? They just let her get battered day in and day out so they could have a good life.

Rachel: You can't blame the kids Sammy. They're just trying to survive.

Lee: She was a little martyr.

Rachel: Yeah.

(Interrogation.)

Lexi: He was hiding Zoe because 10 p went missing from his jeans pocket. I reckon he spent it at the pub and just forgot because he was so pissed.

Anna: Did he normally tie her up?

Lexi: No. She ran out the house, to the back garden. But he caught her. He brought her back in the house and had Mummy Judy tie her hands and feet.

Anna: What was she tied with?

Arianna: Hair scarves.

Lexi: All she had to do was admit that she stole it. But she wouldn't. She kept saying "No." That she didn't do it and then she said what I said, that he probably drank it. And that's when Grandad Tim went mental. He got his cane and said he'd stop when she admitted she was a liar. Mummy Judy made us go in the room, keep out of his way, and we tried to distract ourselves. We played computer games and sang songs. After awhile, we had dinner. Zoe was still tied up on the floor, but we couldn't say anything. So we just ate dinner. (Lexi begins crying.) All she had to do was say she did it! That's it! (Lexi covers her face.)

Anna: Then what happened after dinner?

Lexi: Mummy Judy went out to her mates house, she was sick of it, hearing it, over and over. And so she went to go drink wine. Grandad Tim only stopped because it was bedtime and he brought Zoe into the room. He carried her in. We pretended we were sleeping. Didn't we Ari?

Arianna: I wet the bed. Just because I was frightened, not because I'm a baby.

Lexi: And then he left, he went to the pub. And it were just us and Zoe, and she was breathing. Just barely. But I couldn't get her to open her eyes or say anything. So I called Anthony. Because I didn't know what else to do.

(Viewing room.)

Rachel: As soon as we get forensics from the cane and hair scarves, I want them all charged.

Sammy: The kids?

Rachel: No Sammy. Don't be ridiculous. Timothy, Judy and Anthony.

Sammy: Anthony?

Rachel: If she was still breathing, if he had phoned 999?

Sammy: He said she wasn't breathing by the time he got there.

Rachel: Who knows.

Sammy: And the girls?

Rachel: Well, social services will find them a new home. Hopefully a good one this time.

Sammy: That's all we can do?

Rachel: It's a flawed system Sammy. We did what we can do. In a few hours, we'll be locking up a child beating murderer. And hopefully, these little girls won't be going to bed frightened tonight. So, let's consider that a win.

(A few hours later, Rachel heads down the hallway to watch Timothy get booked. She didn't need to be there when they read him his charges and brought him to be officially locked up but she wanted to see him. She wanted to see his face. Rachel remembers her father's funeral back in 2001. She didn't go because Allison relentlessly nagged her. She went to say a final "Fuck you." To the man that tormented her for years. The open casket was the first time in nearly a year that Rachel had seen him. Since she moved out she stayed as far away as possible, even avoiding a few of her niece's birthdays because she knew he'd be there. Rachel remembers, at the funeral, how her body stiffened as she received a hug from a teary woman who smelled of fags. The woman cried and gripped Rachel tightly probably expecting the hug to be returned but giving up after a few moments.)

Woman: (wipes tears) I'm so sorry for your loss. Your Dad, he was a breath of fresh air. Whenever he walked into my pub, he was all smiles and charm. Always had a joke handy. (Rachel studies this strange woman's face. Was she the bartender that filled his cup? Took his smiles and sent him home boozed up and angry?) I can't imagine your grief. I can't even bring myself to close his tab because I can't bear the thought of him never coming back.

Rachel: The world's a better place now, as far as I'm concerned. (The woman scoffs and grips her chest appalled.)

Allison: Let's not do this here, eh? (Rachel took the cue from her sister and stiffened her stance again. Now Rachel stands beside Timothy, he's angry and quiet, irritated, and sober for probably the most consecutive hours that he had been in ages.)

Lee: - that you did murder Zoe Slater contrary to common law.

Timothy: No great loss. That thieving ungrateful bitch was lucky to have the life she did.

Rachel: Let the big boys in there for life, hear you say that. And see who's a bitch then. (For the first time Timothy makes direct eye contact with her. He glares and she raises an eyebrow, not intimidated by him.)

Desk Sergeant: You heard what the officer said, is there anything you'd like to say? (Timothy shakes his head 'no' and signs the paper. He is brought to his holding cell and when the door opens and he sees the small barren space and metal toilet, for the first time the reality of his situation hits him. Rachel smugly waves goodbye as the prison guard shoves him out of sight. She and Lee begin their walk back to the office.)

Lee: I don't think I've ever seen you hate a suspect more than you hate that guy.

Rachel: Don't be stupid.

Lee: I sat beside you in the court the day the Taking out the Trash killer got his sentence. He got you alone, chased you, tried to kill you and your unborn. You were calm and content the entire time.

Rachel: Because we got him. We got justice.

Lee: This was different. It's like instead of justice you wanted vengeance.

Rachel: Ha, who are you? My therapist?

Lee: No. I've worked for and with you for nearly eight years. There's a lot you learn about a person in that time. I could tell from the start, this was different. (They're alone in the lift and something about the closed space and Lee's calm voice made Rachel feel safe. She presses the button to their floor and leans against the elevator wall.)

Rachel: He, uh, reminded me of me dad. Er, My Dad he was, he was like that. (She peeks to Lee's reaction. Lee nods matter-of-factly but his eyes are sympathetic. She feels a moment of panic. She's never said this out loud to anyone before.) But I don't, please don't make it office gossip.

Lee: No. I won't say a word. (shrugs) We've all got our demons.

Rachel: I was just luckier than Zoe. I survived it.

Lee: Is he why you became a cop?

Rachel: Partly. I knew a lot of bad men. I saw a lot of things children shouldn't and I just remember, being outside in the back garden, tiny and looking at my mum and the other women there, and thinking, I will never be a woman that just let's this happen. I'll lock them up.

Lee: (smiles and the door opens to their floor.) Well, you've done it.

Rachel: (nods and smiles) Yeah.

(The office is closing and Anna has offered to stay a little later to do some filing. Rachel has head out but stopped on her way down the stairs on the landing that she knows led to the Sex Crimes office. It's been nearly impossible to wipe the smile from her face today. Even now as her nerves creep up her smile only momentarily fades. She finally makes the decision to text instead of enter. She turns the corner and takes two steps down, before pulling out her mobile and texting. It's barely 2 minutes that she waits and hears the door to the landing open. Robin stands in the stairwell, baffled by it's emptiness.)

Rachel: Hiya. (She says as she takes a step up. Robin follows her voice and turns the corner smiling down at the sight of her. She wore belted blue trousers, perfectly creased in the leg and a loose fitted white blouse that she tucked in. A few of the buttons were undone and he could see her slender neck and collarbone. He follows her bandaged hand as she pushes some of her dark strands away from her face and settles on her smile.) I just, I know you're still busy, but I just wanted to tell you, well you asked me. You said to tell ya when we caught the monster that battered the little girl.

Robin: You've done it? (His smile is almost as wide as hers now.)

Rachel: Yeah. Locked him up. It was the Grandad, over a missing 10 p if you can believe it.

Robin: What a sick demented fuck.

Rachel: (lightly laughs, almost giddy with the victory and seeing Robin. She could smell his cologne and again she pictures herself on top of him. Imagining him with this same dumb grin he's wearing now.) Anyway, that's all I wanted to tell you.

Robin: Maybe I can take you for a drink, to celebrate?

Rachel: (blushes. He couldn't help but find her cute, and sort of bashful like a schoolgirl.) I've actually got...well, I've got to pick up my kid and then I've got a sort of-

Robin: A sort of 'No'.

Rachel: It's a…(She squints struggling with the word as if it tastes funny.) It's a family dinner.

Robin: Oh, well that's nice.

Rachel: Yeah. I just wanted to, to tell you the good news.

Robin: Thanks for telling me. And thanks for locking up a guy like that. (He pretends to tip a hat to her.) Statistics aside, this is a win for all the little girls who've been victims of bastards like that. Maybe we didn't get your bad guy in particular but we got this piece of shit and he's gonna pay for it all!

Rachel: My bad guy? (Her eyes search his. What could he know?)

Robin: I meant you, not you. Not like you, but like a general sort of you. A hypothetical you. A-

Rachel: Got it. (She smiles and nods.) Right well, I'd better get going.

Robin: Ok. Goodnight. Be safe.

Rachel: Goodnight. (He turns and takes a few steps in the direction of the door. She quickly steps up the final stair tripping a little but catching her balance. He turns around.) Maybe um, tomorrow? (She breathes in and holds her breath. He smiles.)

Robin: Tomorrow, what?

Rachel: Uh, for the drink. (shrugs) If you still want to. Or if-

Robin: Yeah, I'll look forward to it.

Rachel: Okay. (She breathes out.) Okay. Me too. Bye then. (She bites her lip fighting a smile and this time hurries down the stairs away from him.)
