A brilliant book with a well written and carefully crafted story line. I love dark, complex thrillers and this didn't disappoint at all. I'd not read any of Knox's books before but i'm going to go back and read the first two. It was amazing.

Wow where to start with this review. I haven’t read the first two books in the series but this was a thrilling gritty novel with Detective Aiden Waits who seems to have lots going on in his life. He has been relegated to night shifts barely hanging on to his job by a thread guarding a dying serial killer Martin Wicks. Wick’s asks to speak to Wait’s partner Detective Inspector Peter ‘Sully’ Sutcliffe they are hoping Wicks will reveal where his last victim is. But as Sully enters the room where Wick’s is being kept the police officer guarding Him is murdered and a firebomb is thrown into the room where Wicks and Sully are. Waits chases the person he believes to be the one who threw the firebomb into the room down the stairs and out of the hospital. From there it’s very fast paced not knowing who to trust and who not to trust. Aiden is given a new partner Detective Constable Naomi Black whilst Sully lies in an induced coma. But why is Black investigating Waits looking into his background?

This is a very dark gritty detective novel. Aidan is struggling with every aspect of his life. He gets a call from a social worker asking him about his mother who he hasn’t seen since he was 8. The social worker tells him they need to section her as she is a danger to herself. But Aiden is past caring. Martin Wicks claimed he didn’t commit the crimes he is in jail for could he be telling the truth!

Aiden is a recovering drug addict he was caught stealing drugs from police evidence. He relies on drink to keep him going and to stop the panic attacks. Was he the one who was supposed to have died with the serial killer. Another detective is blackmailing him and she could easily bring him down if he brings her down. This book has you gripped from the start it may have been better if I had read the first two novels first as there does seem to be some back story leading to where this book starts. But it was a good standalone read as well. I can’t wait to see which way Aiden turns next as it doesn’t see, like he has a lot of options left but we may be surprised yet.!

The Sleepwalker is a good thriller that has interesting characters. The storyline is great and the book is well written.

I enjoyed reading this book. It had a good story to it. It was a well written book. I liked the variety of characters in it. It is my first book read by this author. I hope to read more books by this author.
