He crossed to the opposite pavement and made his way along the edge of St. John’s Church, past the parish preschool. Tomorrow afternoon at one o’clock, Liddell would be standing there among the mothers and the nannies to greet Emily as she emerged. By judicial fiat he had been rendered little more than a babysitter. Two hours a day was his allotted time, scarcely enough for more than a spin on the merry-go-round and a bun in the sweets shop. Hester’s revenge.

He turned into Church Lane. It was a narrow alleyway bordered on both sides by high stone walls the color of flint. As usual, the only lamp was out, and the street was black as pitch. Liddell had been meaning to buy a small torch, like the ones his grandparents had carried during the war. He thought he heard footfalls behind him and peered over his shoulder into the gloom. It was nothing, he decided, just his mind playing tricks. Silly you, Christopher, he could hear Hester saying. Silly, silly you.

At the end of the lane was a residential district of terraced cottages and semidetached houses. Henley Close lay at the northern-most edge, overlooking a sporting field. Its four cottages were a bit larger than most in the neighborhood and were fronted by walled gardens. In Hester’s absence, the garden at No. 8 had taken on a melancholy air of neglect that was beginning to earn Liddell nasty looks from the couple next door. He inserted his key and turned the latch. Stepping into the entrance hall, he was greeted by the chirping of the security alarm. He entered the disarm code into the keypad—an eight-digit numeric version of Emily’s birth date—and climbed the stairs to the top floor. The girl waited there, cloaked in darkness. Liddell switched on a lamp.

She was seated in a wooden chair, a wrap of jeweled silk draped over her shoulders. Pearl earrings dangled at the sides of her neck; a gold chain lay against the pale skin of her breasts. Liddell reached out and gently stroked her cheek. The years had lined her face with cracks and creases and yellowed her alabaster skin. It was no matter; Liddell possessed the power to heal her. In a glass beaker, he prepared a colorless potion—two parts acetone, one part methyl proxitol, and ten parts mineral spirits—and moistened the tip of a cotton-wool swab. As he twirled it over the curve of her breast, he looked directly into her eyes. The girl stared back at him, her gaze seductive, her lips set in a playful half smile.
