He was red all over his freckles, but he held his ground. “No. I’m trying to do the right thing.”

Sweet Jesus, he was young. “If you don’t know this by now, mate, you’d better write it down and learn it by heart: the right thing is not always the same as what’s in your pretty little rule book. To all intents and purposes, this right here is an undercover assignment that I’m offering you. A bit of moral ambiguity comes with the job. If you can’t cope with it, now would be just a perfect time to figure that out.”

“This is different. It’s undercover against our own.”

“Sunshine, you would be amazed at how often that happens. Amazed. Like I said, if you can’t handle it, not only do you need to know that, but so do I. Both of us might have to do some rethinking about your career goals.”

The corners of Stephen’s mouth tightened. “If I don’t do this,” he said, “I can forget about a place in Undercover.”

“Not out of spite, kid. Don’t fool yourself. A guy could bang both my sisters at once, stick the video on YouTube, and I’d happily work with him, as long as I thought he’d get the job done. But if you make it clear to me that you’re fundamentally unsuited to undercover work, then no, I’m not going to recommend you. Call me crazy.”

“Can I have a few hours to think about it?”

“Nope,” I said, flicking my cigarette away. “If you can’t make this call fast, I don’t need you to make it at all. I’ve got places to go and people to see, and I’m sure you have too. Here’s what it comes down to, Stephen. For the next few weeks, you can be Scorcher Kennedy’s typist, or you can be my detective. Which one of those sounds more like what you signed up for?”

Stephen bit his lip and wrapped the end of his scarf around his hand. “If we did this,” he said. “If. What kind of thing would you be wanting to know? Just for example.”

“Just for example, when the fingerprint results come back, I’d be fascinated to hear whose prints, if any, were on that suitcase, on the contents of that suitcase, on the two halves of that note, and on the window Kevin went out of. I’d also be interested in a full description of his injuries, preferably with the diagrams and the post-mortem report. That might well be enough info to keep me going for a while; who knows, it might even turn out to be all I ever need. And that should be back within the next couple of days, no?”
