A quick tidy-up and hasty smoothing of the bedclothes, then she dressed hurriedly and switched off the electric fire which made strange clanking and clicking noises in its death-throes. A final look round the room. No visible signs of guilt, but the acrid smell of male sweat lingered accusingly. She opened the window and the warm room choked down gulps of cold, black December air. The house across the road had a Christmas tree on display in its upstairs window, a tall fir decorated with glass globes and flaming jewels of colored lights. She would have to see about a tree for Tracey.

A full-throated treble roar echoed from the end of the street. The Sunday school had released its prisoners. The children were coming out. She craned her neck and strained her eyes into the darkness. She should see Tracey soon.

The first wave of children washed past. Tracey wasn't among them, but she always did drag behind.

A pause before the next burst, the children chattering excitedly, "oohing" and "aahing" as they spotted the lights of the Christmas tree.

Then the stragglers. That one at the end must be Tracey. But no

… much older. Then the street was empty. No more children. Silence.

She suddenly realized she was shivering. She closed the window and rubbed the raised goose-pimples on her bare arms. But it was not just the cold that was making her body shake and her teeth chatter. There was also the soft, sibilant, wet-lipped voice of fear whispering in her ear. Telling her that Tracey wasn't going to come. Not tonight. Or ever.

SUNDAY-2

Sunday at Denton Police Station was the same as any other day.
