Love the character - story & plot are fill of twists and turns- the narrator is perfect for the book All together couldn't listen to this book enough - brilliant Already have the next one ready to go!

Great characters who i now feel i know well after 3 books. Narrated brilliantly! Plot twists a plenty I did not see the final twist until the very end. Lots of historical references to Londons underground tunnels. Loved every twist and turn! Downloaded the next book already!!

Fabulous, loved it. Thank you.

A superb read which kept me interested from beginning to end. The authors attention to detail over technical issues was staggering, which just in grossed me even more in the overall story. Gritty, exciting and just waiting for the movie!!

I enjoy this author. His stories are interesting and his characters are believable. I would recommend this story to anyone who enjoys listening to crime fiction. Also, the narrator did a great job with the various accents and tones.
