The only one who didn’t turn into her ma, Imelda’s voice said in the dark beside my ear, rough with a million cigarettes and an infinite amount of sadness. The one that got away. Imelda and I were a pair of liars born and bred, but she hadn’t been lying about loving Rosie, and I hadn’t been lying about her being the one who had come closest. Imelda, God help her, had understood.

The yuppie baby had fallen asleep, in the safe glow of his night-light. His ma stood up, inch by inch, and slipped out of the room. One by one, the lights started to go out in the Place: Sallie Hearne’s Santas, the Dwyers’ telly, the Budweiser sign hanging crooked in the hairy students’ gaff. Number 9 was dark, Mandy and Ger were snuggled up together early; probably he had to be in work at dawn, cooking businessmen their banana fry-ups. My feet started to freeze. The moon hung low over the roofs, blurred and dirty with cloud.

At eleven o’clock on the dot Matt Daly stuck his head into his kitchen, had a good look around, checked that the fridge was closed and switched off the light. A minute later, a lamp went on in a top back room and there was Nora, disentangling her hair elastic with one hand and covering a yawn with the other. She shook her curls free and reached up to draw the curtains.

Before she could start changing into her nightie, which might make her feel vulnerable enough to call Daddy to deal with an intruder, I tossed a piece of gravel at her window. I heard it hit with a sharp little crack, but nothing happened; Nora had put the sound down to birds, wind, the house settling. I threw another, harder.

Her lamp went out. The curtain twitched, just a cautious inch. I flicked on my torch, pointed it straight at my face and waved. When she had had time to recognize me, I put a finger to my lips and then beckoned.

After a moment Nora’s lamp went on again. She pulled back a curtain and flapped a hand at me, but it could have meant anything, Go away or Hang on. I beckoned again, more urgently, grinning reassuringly and hoping the torchlight wouldn’t turn it into a Jack Nicholson leer. She pushed at her hair, getting frustrated; then—resourceful, like her sister—she leaned forward on the windowsill, breathed on the pane and wrote with a finger: WAIT. She even did it backwards, fair play to her, to make it easy for me to read. I gave her the thumbs-up, switched off the torch and waited.
