'Quite simply one of the best cop thrillers you'll read this year. Or any year. It's an achievement that parks Ellory's wagon on the driveway of Michael Connelly, the finest American exponent of the genre, and no higher praise can I give.' EVENING TELEGRAPH 'The prose is daring and he is head and shoulders above his contemporaries.' CATHOLIC HERALD 'This thriller was so gripping it had me holding my breath as I turned the pages' ESSENTIALS 'a serial killer story unlike any other...it grips like a claw' EVENING TELEGRAPH 'This is one of those police-procedural gems that come along once in a blue moon.' -- Elliott Swanson BOOKLIST 'This man [Ellory] is incapable of writing a mediocre book. All are, without doubt, first class.' LOVEREADING.CO.UK 'This is one of Ellory's fastest reads, a real page-turner, gruesome, at times chilling, building to an edge-of-the-seat climax. Awesome.' LOVEREADING.CO.UK 'Ellory's gripping thriller should appeal to lovers of procedurals and may also draw readers of true crime, as it deals with many actual serial killings.' LIBRARY JOURNAL (USA)
