I said blandly, “Either one.”

“She was going out with Pat! Like seriously going out, not just kid stuff. They were in love. And Jenny’s not some kind of two-timing— That’s my sister you’re talking about.”

I raised my hands. “I’m not doubting for a second that they were in love. But a teenage girl, just starting to realize that she’s going to spend the rest of her life with the same man: she could panic, feel like she needed one little moment with another guy before she settled down. That wouldn’t make her a slut.”

Fiona was shaking her head, hair flying. “You don’t get it. Jenny— When she does something, she does it properly. Even if she hadn’t been crazy about Pat—and she was—she’d never cheat on anyone. Not even a kiss.”

She was telling the truth, but that didn’t mean she was right. Once Conor’s mind started breaking loose from its moorings, one old kiss could have grown into a million sweet possibilities, swaying just out of reach. “Fair enough,” I said. “What about confronting Conor? Would she have done that?”

“I don’t think so. I mean, what for? What good would it have done? It would’ve just embarrassed everyone, and maybe messed up Pat and Conor. Jenny wouldn’t have wanted that. She’s not some drama queen.”

Richie poured boiling water. “I’d have said Pat and Conor were already well messed up, no? I mean, even if Pat didn’t give Conor a few slaps that day, he wasn’t a holy martyr. He couldn’t exactly keep on being mates like nothing had happened.”

“Why not? It’s not like Conor had done anything. They were best friends; they weren’t going to let something like that wreck everything. Is any of this … ? Why … ? I mean, it was like eleven years ago.”

Fiona was starting to look wary. Richie shrugged, dumping a tea bag in the bin. “I’m only saying: they must’ve been pretty close, if they got past something like that. I’ve had good mates in my time, but I’ve got to say, any of that carry-on and they’d’ve been on their bikes.”

“They were. Close. We all were, but Pat and Conor, they were different. I think …” Richie handed her a fresh mug of tea; she swirled the spoon in it absently. She was concentrating, feeling for the words. “I always thought it was because of their dads. Conor’s dad, like I told you, he wasn’t around, and Pat’s dad died when he was like eight … That makes a difference. To guys, especially. There’s something about guys who had to be the man of the family when they were just kids. Guys who had to be too responsible, too early. It shows.”

Fiona glanced up; our eyes met, and for some reason hers skipped away, too quickly. “Anyway,” she said. “They had that in common. I guess it was a big deal to them both, having someone around who understood. Sometimes they used to go for walks, just the two of them—like down the beach, or wherever. I used to watch them. Sometimes they wouldn’t even talk; just walk, like close together, so their shoulders were practically touching. In step. They’d get back looking calmer; smoothed out. They were good for each other. When you’ve got a friend like that, you’d do a lot to hang on to him.”
