They used the opulent staff room on the main floor; with Beckett choosing the end of the table farthest away from the door - they'd chosen it to give them a little privacy in case someone was walking past and their ears got a little too big.

'Anna is in for a rough time with this,' he said to Beckett.

'Yeah, it's going to damage her rep as an administrator one hundred percent.'

'You think so?'

Beckett looked away from the window, where she'd been watching the traffic come and go, saw teachers coming in by the south end of the building. How many of them were about to have their world shattered because of the screw-up of someone they thought was a trusted colleague. It reminded her of the Raglan case, revisiting the ghosts of her own past and discovering with no little devastation that the man they'd been gunning for the entire time was the same man they thought had their backs to protect them against the other dirty cops they'd uncovered.

She shook her head. Therapy, lots of both the clinical and chocolate kind, had helped her find closure with that moment and she knew she'd be able to tell the others with absolute certainty talking about it would help.

Beckett steeled her senses when the door opened and Carolina Witt came in with Anna Leung. For a moment, Beckett was struck by how much she resembled Evil Meredith - both had the classic oval face with green eyes and dark red hair, and perhaps fittingly enough they were both users looking for means to their own ends. She wasn't surprised when she saw the light of righteous indignation in the woman's eyes - she'd seen the same look on Evil Meredith's face when Alexis had thrown her out of her wedding rehearsal dinner.

What would the woman's face look like in several minutes time when Beckett and Adam dropped the bombshell? More importantly, what would Anna's look like?

'Miss Witt, thank you for meeting with us,' Beckett told her with all professional politeness. 'Please, have a seat.'

'I'm not sure exactly why I'm here, I thought you were going to be addressing the faculty entirely at our staff meeting,' Carolina replied smoothly, sitting down as she pressed her fingertips lightly to her lips.

'Are you not feeling well?' Adam asked, complete innocence.

'Morning sickness. I just found out I'm pregnant.'

'Congratulations.'

'Well, it was just a home test, took it before my husband got in from work last night. We're going to see the doctor later today.'

'I hope the stress of this situation isn't going to be too much for you.'

'Death is always stressful,' Carolina sighed dramatically. 'I'm just worried about my students.'

Not her daughter, Beckett noted; Carolina was very careful to make that distinction. She pulled out the file with Micah and Shane's early morning discoveries. 'Miss Witt, before we go any further, I need to inform you of your rights for your own protection. It's a standard formality.'

'Okay.'

Beckett recited the Miranda warning, then tapped her finger on the file folder. 'Miss Witt, our evidence teams have come across some very important information from a highly credible source close to you that bears investigating. I need to ask you for your whereabouts yesterday morning from seven forty-five until nine-forty-five.'

'I- my home-room is my prep period, I was in the gymnasium getting equipment ready for my third period class. My third period class is second-year health. We've just started a unit on contraception and its different cultural and social implications from around the world.'

Oh, Rick, you'd love that one, Beckett thought with a little irony. 'Did you see anyone?'

'I...I can't remember. I haven't slept well this past week.'

'I'm sure you haven't.' Now Beckett dropped the nicey-nice pretense and leaned forward. 'Telling your husband you're having another man's child isn't something that would be easy for a lot of women.'

'What?' Anna actually laughed. 'That's absurd.'

'No it's not.' Beckett shoved over the file folder with the evidence in it. 'What's even more devastating is that our ME was able to work his magic in the lab and tell us that not only is Carolina pregnant, but the timing means that her baby daddy was a student and a minor at the time of the conception.'

Adam knew if real-life had comedic interstitial animations, they would currently have one of Carolina's head blowing to smithereens, just like in Scanners. Her face went even paler than normal, and her hands trembled as she took the files from Beckett to examine them.

'This is crazy, how dare you accuse me of something so gross and wrong!'

'But if you have a look there, you'll see our source brought us your pregnancy test-stick and the box it came in, Carolina. We ran multiple tests and have conclusive evidence to support our investigative theory.'

'That's preposterous,' she spluttered. 'How could you possibly know I took a pregnancy test, I was at home yesterday afternoon and the only other person there was...Ashley. That lying little bitch, oh I'll kill her for this!'

'Easy, Miss Witt. You know what stress does to a baby,' Adam cautioned her dryly.

'How could she do this to me?'

'You did this to yourself, Carolina,' Beckett replied calmly, noting that Anna had yet to say anything. She picked up the file, opened it to the comprehensive test results from the morgue and its labs. 'This tells us that you had an affair with your student and you are now pregnant by him, and that you're-'

'Who is it?'

'Excuse me?'

Carolina's lips curved; she straightened in her chair as her brainstorm gave her new energy. 'You don't have anything, otherwise you'd tell me a name.'

'Oh, sorry about that. It's Farley McBride.'

'No.' It was a single, disbelieving protest from Anna, watching as Carolina slumped back in her chair. 'No, this...this can't be.'

'There's no way you can prove it,' Carolina sneered.

'Oh but there is. We have some cool toys on our side, and they can do things like track serial numbers of products, not to mention the awesome old-school trick of pulling fignerprints. After we discounted the employees there is also your fingerprints and Farley's as well.'

'On the box, sure. I bumped into Farley at the drug-store last evening and he handed me the box. Anything else is hearsay.'

'But we also found them on the stick itself. The part you have to open up the box to get at, Carolina. Why would his prints be on that part of the pregnancy test?' When Carolina said nothing, Beckett folded her hands on the desk. 'There is also the matter of how far along you are. Our lab techs were able to determine the hormone levels of your DNA sample and they put the time of conception between June nineteenth and June twenty-sixth. Any specials events going on that you were chaperoning Carolina?'

'The senior prom,' Anna jumped in, her expression frozen. 'The senior prom was June twenty-second. It was hosted at the Tesla Concorde and a group of the seniors had rented out a floor for an after party. Carolina, you volunteered to keep an eye on them and make sure they didn't get too rowdy, you...you said you'd be fine with it, that you'd love your students to see more of you outside the class.'

Anna's voice broke, and she rose, excusing herself to the end of the room where she retrieved tissues. In her absence, Adam leaned forward as well. 'Carolina, do you understand this makes you our number one suspect?'

'That was for murder, not sex.'

'Oh, but see, here's the thing. Our techs ran even more tests and they know you banged Professor Hill within ninety minutes of his time of death. You had a hell of a motive for wanting him dead, and you could use your baby daddy's baby bro to do it, too.'

'What is my motive?'

'Desperation to conceal a crime. You knew that Farley was seventeen when you two hooked up. I'm guessing you've been showing signs of pregnancy before today since you're probably ten weeks in or so, and Hill figured it out. He knew you weren't doing your mister anymore and he'd have been able to deduce the rest. So when he told you about it, you poisoned him.'

'No, I didn't, and I'd like to exercise my right to counsel now.'

'Call them up, they can meet us at the precinct.'
