Jess Mayor has never been afraid of the dark. Until now.

When a night out ends in tragedy and a body pulled from the canal, everyone apart the victim's family moves on. It was just an accident, wasn't it?

But as Jess puts herself in danger in search of the truth, it will mean facing up to who really lurks in the shadows. And some things are better off left in the dark...
