I've not read any of Shaun Hutson's books for a long while but this one caught my eye - and I'm glad it did.
It is the story of a bunch of detectives and their search for the maker of what could be snuff movies. It seems someone is having people hunted and killed for 'entertainment' but the officers have nothing to go on - until the DI leading the case becomes the target.
The book reads like something similar to the Saw movies or a pretty gruesome video game. Some of the scenes were slightly disturbing but horror isn't meant to be nice. At times it was slightly predictable but that doesn't stop it being an enjoyable, pedal to the metal read.
Maybe not for the faint hearted but if you've got the stomach for it you're in for a good time
