AMY CROSS

Derek Dunne has been a taxi driver in London for longer than he cares to remember. Every night he heads out to help people get home, but every night he's also haunted by the memory of a fare from many years earlier.

As a young man, Derek once picked up a terrified woman and took her to a certain house on a certain street. He knew something was wrong but he didn't dare to intervene, and the woman was later found murdered and horribly mutilated. And while Derek has always tried to convince himself that he couldn't have done anything, that the woman's fate wasn't his fault, a tiny part of him still fills with dread whenever he has to drive down that road.

And then one night he sees her again.
