Richie said, “Let’s talk to the uniform now. Before the ma wakes up.”

In the heavy gray light he looked terrible, eyes bloodshot, face flat and haggard; if it hadn’t been for the half-decent clothes, Security would have taken him for a junkie. The kid was exhausted. It was heading for three o’clock. Our night shift started in five hours.

“Go ahead,” I said. “Give him a bell.” Richie’s face told me I looked as bad as he did. Every breath I took was still clotted with disinfectant and blood, like the hospital air had closed around me and soaked into my pores. I almost wished I smoked. “And then we can get away from this place. Time to go home.”

I dropped Richie outside his place, a beige terraced house in Crumlin—the tattered paintwork said it was rented, the bikes chained to the railings said he was sharing with a couple of mates. “Get some sleep,” I said. “And remember what I said: no booze. We need to be on the ball for tonight. I’ll see you outside HQ at a quarter to seven.” As he put his key in the door, I saw his head drop forward like he had nothing left to hold it up.

Dina hadn’t rung me. I had been trying to take that as a sign that she was peacefully reading or watching telly, or maybe still asleep, but I knew she wouldn’t ring even if she was bouncing off the walls. When Dina’s doing well, she’ll answer texts and the occasional call; when she’s not, she doesn’t trust her mobile enough to touch it. The closer I got to home, the more that silence seemed to turn dense and volatile, an acrid fog I had to fight through to reach my door.

Dina was sitting cross-legged on my living-room floor, with my books strewn around her like a hurricane had flung them off the shelves, ripping a page out of Moby Dick. She stared me in the eye, tossed the page on a pile in front of her, threw the Melville against the opposite wall with a bang, and reached for another book.

“What the fuck—” I dropped my briefcase and grabbed the book out of her hand; she kicked out at my shin, but I leapt back. “What the hell, Dina?”

“You, you fuckety bastarding prick, you locked me, what was I supposed going to do, sit here good girl like your dog? You don’t own you can’t make me!”

She made a dive for another book; I dropped on my knees and caught her wrists. “Dina. Listen to me. Listen. I couldn’t leave you the keys. I don’t have a spare set.”

Dina laughed, a high yelp that bared her teeth. “Yeah yeah yeah right, you don’t, Mr. Anal with your books are alphabetized but no spare keys? You know what I was going to? Put this on fire.” She jerked her chin fiercely at the heap of torn pages in front of her. “Then let’s see if someone doesn’t let me out, smoke alarm going good and loud, all your snobby yuppie neighbors wouldn’t be happy then, would they, ooh darlings the noise, in a residential area—”
