She said, “You’re sure, too, right? This will work. It’s not going to go all wrong. You’re sure.”

“It isn’t perfect. Some people, possibly including the prosecutor, are going to think that you knew all along and deliberately held back. And some people are going to wonder if the whole thing is just a little too convenient to be true—department politics; you don’t need to know the details. I can make sure you don’t get into any actual trouble—you won’t be arrested for concealing evidence or obstruction of justice, nothing like that—but I can’t make sure you won’t get a tough time from the prosecutor, or the defender if it gets that far. They may even try to imply that you should be a suspect, given that you’d have been the beneficiary if Jenny had died.”

Fiona’s eyes snapped wide. “Don’t worry,” I said. “I promise, there’s no way that could go anywhere. You’re not going to get in trouble. I’m just telling you in advance: this isn’t perfect. But it’s the best I can do.”

“OK,” Fiona said, on a deep breath. She pulled herself upright in the chair and pushed hair off her face with both hands, ready for action. “What comes now?”

“We need to do it, conversations and all. If we go through every step, then you’ll remember the details when you give your statement, or when you’re cross-examined. You’ll sound truthful, because you’ll be telling the truth.”

She nodded. “So,” I said. “Where are you off to, Ms. Rafferty?”

“If Jenny’s asleep, I should drive down to Brianstown. She needs some things from the house.”

Her voice was wooden and empty, nothing left in it but a sediment of sadness. I said, “I’m afraid you can’t go into the house. It’s still a crime scene. If it would help, I can take you down there and get out whatever you need.”

“That’d be good. Thanks.”

I said, “Let’s go.”

I stood up, bracing myself against the wall like an old man. Fiona buttoned her coat, wrapped the scarf around her neck and tugged it tight. The child had stopped crying. We stood there in the corridor for a moment, listening by Jenny’s door for a call, a movement, anything that would keep us there, but nothing came.

For the rest of my life I will remember that journey. It was the last moment when I could have turned back: picked up Jenny’s bits and pieces, told Fiona I had spotted a flaw in my grand plan, dropped her back at the hospital and said good-bye. On the way to Broken Harbor that day, I was what I had given all my adult life to becoming: a murder detective, the finest on the squad, the one who got the solves and got them on the straight and narrow. By the time I left, I was something else.

Fiona huddled against the passenger door, staring out the window. When we got onto the motorway I took one hand off the wheel, found my notebook and pen and passed them to her. She balanced the notebook on her knee and I kept my speed steady while she wrote. When she was done she passed them back to me. I took a quick glance at the page: her handwriting was clear and rounded, with fast little flourishes on the tails. Moisturizer (whatever’s on bedside table or in bathroom). Jeans. Top. Jumper. Bra. Socks. Shoes (runners). Coat. Scarf.
