He sounded breathless, winded. I didn’t know whether to hold him tight or kick him. “What makes you think this has nothing to do with me?” I demanded. “This girl is my double, Sam. This girl was going around wearing my fucking face. How do you know your guy got the right one? Think about it. A postgrad who spends her time reading Charlotte bloody Brontë, or a detective who’s put dozens of people away: who’s more likely to have someone out to kill her?”
There was a silence. Sam had worked on Operation Vestal, too. Both of us knew at least one person who would happily have had me killed without a second thought, and who was well able to get the job done. I could feel my heart banging, hard and high under my ribs.
Sam said, “Are you thinking-”
“Specific cases aren’t the point,” I said, too curtly. “The point is, for all we know I could be involved up to my tits already. And I don’t want to be looking over my shoulder for the rest of my life. I can’t live with that.”
He flinched. “It wouldn’t be for the rest of your life,” he said, quietly. “I hope I can promise you that much, at least. I do plan to get this fella, you know.”
I leaned back against the counter and took a breath. “I know, Sam,” I said. “I’m sorry. I didn’t mean it that way.”
“If, God forbid, he was after you, then all the more reason to stay out of the way and let me find him.”
The cheerful cooking smell had grown an acrid, dangerous edge: something was starting to burn. I switched off the cooker, shoved the pans to the back-neither of us was going to feel like eating for a while-and sat down cross-legged on the sofa, facing Sam.
“You’re treating me like your girlfriend, Sam,” I said. “I’m not your girlfriend, not when it comes to this kind of thing. I’m just another detective.”
He gave me a sad, sideways little smile. “Could you not be both?”
“I hope so,” I said. I wished I hadn’t finished the wine; this man needed a drink. “I really do. But not like this.”
After a while Sam let out a long breath, let his head fall back against the sofa. “So you want to do it,” he said. “Mackey’s plan.”
“No,” I said. “I just want to know about this girl. That’s why I said I’d go to the meeting. It’s got nothing to do with Frank and his wacko idea. I just want to hear about her.”
“Why?” Sam demanded. He sat up and caught both my hands, making me look at him. There was a ragged edge to his voice, something frustrated and almost pleading. “What’s she got to do with you? She’s no relation to you, no friend of yours, nothing. She’s happenstance, is all, Cassie: some girl who was looking for a new life and ran into the perfect chance.”
“I know,” I said. “I know, Sam. She doesn’t even sound like a particularly nice person; if we’d met, I probably wouldn’t have liked her. That’s the whole point. I don’t want her in my head. I don’t want to be wondering about her. I’m hoping that if I find out enough about her, I can drop the whole thing and forget she ever existed.”
“I’ve a double,” Sam said. “He lives in Wexford, he’s an engineer, and that’s all I know about the man. About once a year, someone comes up to me and tells me I’m the spit of him-half the time they actually call me Brendan. We have a laugh about it, sometimes they take a photo of me on their phones to show him, and that’s the end of that.”
I shook my head. “That’s different.”
“How?”
“For one thing, he hasn’t been murdered.”
“No harm to the man,” Sam said, “but I wouldn’t give a damn if he were. Unless I caught the case, it’d be no problem of mine.”
“This girl’s my problem,” I said. Sam’s hands were big and warm and solid around mine, and his hair was falling across his forehead like it always does when he’s worried. It was a spring Saturday night; we should have been walking on some beach down the country, surrounded by dark and waves and curlews, or making something experimental for dinner and playing music too loud, or settled in a corner of one of those rare out-of-the-way pubs where people still sing ballads when it gets past closing time. “I wish she wasn’t, but she is.”
“There’s something here,” Sam said, “that I’m not getting.” He had let our hands drop onto my knees and was frowning down at them, running his thumb around one of my knuckles in a steady, automatic rhythm. “All I’m seeing is a bog-standard murder case, with a coincidence that could happen to anyone. Sure, I got a shock when I saw her, but that’s only because I thought it was you. Once that was sorted, I figured everything would go back to normal. But you and Mackey, you’re both acting like this girl was something to you; like it’s personal. What am I missing?”
“In a way,” I said, “it is personal, yeah. For Frank, partly it’s exactly what you said-he thinks this would all be a big brilliant adventure. But it’s more than that. Lexie Madison started out as his responsibility, she was his responsibility for eight months while I was under, she’s his responsibility now.”
