When forensics specialist Liam is called out to a crime scene he discovers the victim is his ex-lover. Unfortunately, he has no memory of where he was at the time of her brutal murder. Liam's brother, Sean, is a homicide detective and tries to help but all evidence points to Liam. As Liam digs deeper for the truth he starts to suspect that it might actually be Sean. Will they get to the truth and will it tear the family apart?

I really enjoyed this book, it's well written and has a good pace to it which really builds towards the end. It kept me hooked and I was desperate to get to the truth. I did guess who had done it and was suspicious of another character but this didn’t detract from the tension at all and I was hooked until the end.

We occasionally get to go back to the boys past which adds the question of whether you can inherit a gene to make you do bad things. It also explains why the boys are so close and added to the story without over complicating it.

I will definitely be keeping an eye out for more of Matthew Farrell's work.

Thanks to NetGalley & the publisher for a copy of the book
