‘Or towards Julia,’ I said. ‘She made sure to tell us Julia was sneaking out right up until the murder, did you notice?’

‘Julia and Finn,’ Conway said. Forehead-smack. ‘I knew there had to be a reason why Finn decided to hotwire the fire door all of a sudden. He wouldn’t say. I should’ve known. Same as everything fucking else today.’

I said, ‘Why was everyone keeping their love lives secret, but? When I was a young fella, if you had a girlfriend, you told the world. Did girls keep this stuff under wraps, when you were that age?’

‘Fuck, no. That was half the point of going out with someone to begin with: show everyone that you had a fella. That meant you were a success, not some pathetic single loser. You’d shout it from the rooftops.’

‘And this generation, they care a lot less about privacy than we did. Everything goes online, unless it’s embarrassing or it’ll get them in trouble.’

A kid came out of the third-year common room and headed towards the jacks, frantically trying to check us out without looking at us. Conway swung back into Joanne and Company’s room, kicked the door shut. ‘Even then. My cousin’s kid had a pregnancy scare; what’s the first thing she did? Put it on Facebook. Then got pissed off with her ma for finding out.’

‘And they weren’t shy about telling us who they’re going out with now,’ I said. ‘Joanne gave us the bit of hassle, but that was just to be a bitch to you, not because she actually wanted to keep it secret. So what was different last year?’

Conway had started pacing circles around the room again. Whatever poor bastard ended up partnered with her, he was going to spend a lot of his time dizzy. ‘That crap Joanne gave us, about her and Chris keeping it to themselves because they were sooo intense or whatever the fuck. You believe that?’

‘Nah. Load of bollix.’ I leaned against the wall, one-shouldered so I could keep an eye on that line of light around the door. ‘I don’t know about Julia and Finn, but the others: Chris was the one that wanted things on the down-low. I’d bet it was so he could keep a few girls on the go at once. Joanne started pressuring him to go public, he dumped her.’

Nod. She nodded sideways, on a twist, street style. ‘Looks like your Holly might’ve been right about Chris. Not the sweetheart everyone said.’

He only cared about what he wanted, Holly had said.
