Annie insisted that she felt well enough to make the call. She was damned, she told Banks, if she was going to be excluded after all the footwork she’d done just because some over-testosteroned lout had punched her in the mouth. It was her pride that hurt more than anything. After she’d cleaned up the wound, it didn’t look too bad anyway. Some women, she went on to say, paid a fortune for collagen shots to make themselves look like she did. Banks decided he would make the call with her before setting off for Peterborough. He phoned and arranged to meet Michelle in a city center pub at nine o’clock, just to be on the safe side.

Martin Armitage was cooling off in the custody suite and Norman Wells was in Eastvale General Infirmary. No doubt there would be recriminations from Armitage’s pal the chief constable, but for the moment he could stay where he was. They could also charge him with assaulting a police officer. After they had visited the mystery girl.

Within twenty minutes of getting the address, Banks and Annie climbed the lino-covered stairs and knocked on the door. The building seemed so silent that Banks couldn’t imagine anyone being at home, but only seconds later a young woman opened the door. The young woman.

“DCI Banks and DI Cabbot,” Banks said, flashing his card. “We’d like a word.”

“You’d better come in then.” She stood aside.

One reason why it had taken so long to locate her was obvious to Banks: she didn’t look anywhere near as weird as the description Josie Batty had drawn of her, which was hardly surprising when you imagined that most young people probably looked weird to Josie Batty.

The pixyish facial features were right enough, the heart-shaped face, large eyes and small mouth, but that was about all. She was far prettier than Josie Batty had indicated to the police artist, and she had a pale, flawless complexion. She also had the sort of breasts adolescent boys, and many grown men, dream about, and her smooth cleavage was shown to advantage by the laced-up leather waistcoat she wore. The small tattoo on her upper arm was a simple double helix, and there was no sign of body-piercing anywhere except the silver spiderweb earrings dangling from her ears. Her short black hair was dyed and gelled, but there was nothing weird about that.

The flat was clean and tidy, not a filthy crack house full of sprawled drug-addled kids. It was an old room with a fireplace complete with poker and tongs, which must only have been for show, as a gas fire filled the hearth. Sunlight shone through the half-open window and the sounds and smells of South Market Street drifted up: car exhaust and horns, warm tar, fresh-baked bread, take-away curry and pigeons on the rooftops. Banks and Annie walked around the small room, checking it out, while the girl arranged beanbag cushions for them.

“Elizabeth, is it?” asked Banks.
