This is a gripping, rollercoaster of a thriller. It kept me hooked from beginning to end. It‘s fast paced, the action never letting up, with plenty of twists and turns and the odd red herring. The murders are quite gruesome so not it‘s for the faint hearted. I really enjoyed it, especially as the hero of the hour is a Boxer dog called Harvey! I‘ve already downloaded book two in the series. Highly recommended. #Pigeonhole
