The two detectives rolled into the morgue and weren't sure what to find more disturbing - the half-opened body on Shane's table or the fact he was actually humming to himself while he pulled out the man's stomach for further examination.

'Morning sex,' Adam muttered, a little jealous since he'd pussed out on Lindsay and fallen asleep before they coudl do anything worthwhile in bed the night before.

'That's my little girl you're inadvertantly talking about,' Beckett teased him back; she was really relishing being Mumum to him on this particular case. Probably because he was so damn nervous and excited for the wedding. 'But right now I'd have to agree.'

'Morning sex yes,' Shane told them as they stepped closer, 'but not for me. Alexis was sleeping like an angel when I rolled in here an hour ago.'

The doctor removed his hands from the chest cavity and as he tugged down his scrubs mask, Beckett could see he had a mile-wide grin on his face. 'Shane, you and Alexis have news or something?'

'No, no,' he replied, 'I just have a very bad case of the mother-damns right now. Kommen sie hier, bitte.'

'Wow, must be big if a Jew is bustin' out his German,' Adam teased him as they followed Shane to his work bench; he disposed of his gloves before picking up a file and handing it to them. 'Where do you wanna start the mother-damn, or the two syllable day-um?'

'Whatever is the most jaw dropping save it for last.' As Beckett could sense Shane had put someting into his presentation of this information, she gave him a little latitude.

He held up the report first. 'Your vic definitely had sex with your female teacher with the easily-dropped panties. The female contribution to the genital area belonged to Carolina Beverly Witt, currently employed by Calliope Thrace.'

'Why is Carolina's DNA on file?'

'It's standard for teachers, so they can cross-reference it against the National Database of Registered Sex Offenders to make sure there's no threat to the minors they work with. They wanna make sure that if you fucked with the wrong rhino in Kentucky, you didn't come to New York to escape it.'

There's all kinds of predators, Beckett thought, but Shane was already barreling on.

'The evidence suggests they had sex within the hour, ninety minutes tops of his death.'

'But that means...' Adam did the calculation. 'Oh, mother damn! That's just nasty! They did it at the school?'

'Guess that gives hot for teacher a new meaning,' Beckett said dryly.

'And that the least icky of our pirate ships today,' Shane continued. He reached over on the paper outbox of his bench and reached for the pregnancy test box in the plastic evidence bag. 'Ran the prints and the DNA from said prints on the box. Two pops in the system. Carolina Witt and another male contribution from one Farley McBride.'

'McBride, why does that name sound familiar?'

'We talked to his younger brother Dexter,' Adam replied, recalling the information on the boy. 'He was one of the kids rejected from Hill's AP junior class.'

'Right, right.' Beckett looked at Shane. 'He's got a record?'

'Part of the Lost and Found initiative, where children would register their DNA with the cops so that in the event they were abducted their prints and blood would be on file.'

'Okay. So how does he fit?'

'Micah being the intrigued and thorough sort ran the McBride name and the serial number of the preggo-test, and guess what? No-one by the name of Farley McBride works at the store where this test was bought.'

'Which means that he was with Carolina when she bought it, or when she took the test, or both.'

'But wait, there's more, and this is where you will really plotz.' Shane pulled out another sheet. 'We're being used as guinea pigs by Rockefeller for this awesome software they want to use in hospital, where we can test a mother-to-be's blood, run the hormone patterns and get basic match comparisons if the male contributor is also on file as well.'

'You can do that? Seriously?' Adam goggled.

'Welcome to the twenty-first century of medical innovations. You might not be able to use it in court, but if you can use it now to investigate you'll be able to build from that. Plus you've got the prints.'

'I'm not seeing the Robin-Sparkles levels of epic I was promised, Scheine,' Beckett told him, using his actual name.

'Let me get there, Detective.' Shane wasn't about to let his mother-in-law's surliness get him down because he knew he had the upper-hand. 'The preggo stick had a little bit of blood on it, about half-a-dime size which is more than enough for a hematologist like Micah to work with. He ran it through the software and got the pattern, ran it through the police database and wouldn't you know?'

He tapped his finger against Farley McBride's name. 'Your boy's a baby-daddy for his teacher.'

'Well fuck me.'

'Five bucks says that's what Carolina said to Farley,' Adam muttered quietly enough to earn nothing more than a reproachful look from his senior detective.

'Oh, but it gets better still.' Shane was practically glowing with schadenfreude now, and he flipped another page for them. 'One of the other little perks of this software is we're also able to date the age of the pregnancy with in a week. She got pregnant the week of June nineteenth to the twenty-sixth. Have a look at Farley's info there.'

'Farley Merrick McBride born July twenty-fourth, two-thousand...' Beckett trailed off as she did the calculations and felt her jaw drop. 'Oh...oh fuck me senseless on a Sunday.'

'He was a minor,' Adam breathed. 'He was a minor when they had sex and he was still in school.'

'This is beyond Robin Sparkles epic, this is like Disneyland on Prozac for our investigation. We now have motive of a very tangible sort.'

Beckett snapped the folder closed and grinned toothily at Shane. 'If it weren't the height of weirdness, I'd actually kiss you right now.'

'Save it for my father-in-law, Kate,' he teased her, 'and I'll take it home to Alexis later.'

'Come on, Adam,' Beckett said, the light of deliciously anticipated battle in her eyes. 'We've got a private school faculty meeting to blow up.'

'Why are you so happy?'

'What's that?'

Beckett parked the car outside Calliope Thrace, looked over at Adam who looked sincerely pained. 'We've got a viable lead, a woman who approaches rapper's delight levels of sluttiness and you are confused why I'm happy?'

'No, but I've worked with you a while and...okay, I gotta ask it, Beckett, are you this happy because you have a chance to prove me wrong?'

'No, Adam.' Now Beckett's tone was serious. 'I'm this joyful because we have hard evidence to put a predator behind bars. How would you feel if you had someone you trusted, someone in an authority position like a teacher is abusing the trust of the young andvulnerable and has no respect for professional boundaries?'

'Okay, but you get me, right? I never like Nicky Tomasi from the start and if I hadn't had such strong feelings about him, would you be this gleeful?'

'Yes, I would. Like I said, people in positions of authority, especially to children, deserve to be tarred and feathered in my book but the New York Police Department frowns on feathers because it clogs up the air shafts for the subway.'

It made Adam laugh and he was glad for the levity as they climbed the steps, headed for the main office. They found Anna Leung by a photocopier looking just as white and numb as she had the day before.

'Professor Leung?' Beckett had learned this was her title outside of the office and addressed her with the same respect she expected back.

'Oh, Detectives,' she said on a little sigh. 'I wasn't expecting you so early. I take it you must have news?'

'Yes. We need to speak to Carolina Witt and we need you as well.'

'I take it she's in trouble, she was involved in Wayne's death? She told me yesterday afternoon, confessed about their...involvement, and I was absolutely blown away. No-one here had, or has, any clue about it.'

Beckett swallowed tightly. 'Then I'll also suggest you ask your teacher's union rep to be present as well.'
