'I'm going to tell you about the worst thing that ever happened to me.'

Will's a nice guy. So when he takes a shortcut to the tube station after a few beers with his mates from work, he steps out of the way of the fellow who's staggering towards him. But he - deliberately - moves back into his path.

They knock each other as they pass. Moments later one man is dead and another's life is changed forever. Or is it? There are no CCTV cameras.

There was no one else in the out-of-the-way alley. Maybe the world doesn't have to end for Will after all. But there's always someone watching...and Will's life is about to implode.

'An exciting, fast paced and tense thriller that will have you gripped as you shout at the pages' Nadine Matheson, author of The Jigsaw Man
