Black Peter was too addled to be able to make something of his tiny chances with the girl.
She always seemed so alone. She held her head like a bossy dinosaur but in the quiver of her mouth lay so much uncertainty. She was lovely and vulnerable and hard to resist. She had no fear of strangers for she had become disconnected from her own body and any pleasure or harm that befell it.
She wasn't too bothered about what happened behind the building, just so long as she found the place in the end.
