When it comes to crime novels designed to chill the blood in their unblinking treatment of the darkest recesses of human behaviour, Mo Hayder is unquestionably in the forefront of British practitioners in the field. What is even more striking is the fact that more than any other female writer, she is moving comfortably in the bloody territory that has long been the traditional prerogative of male writers, and never for a second allows her writing to be any less disturbing than that of her male confrères.

Ritual is par for a course where this writer is concerned: a tough, scarifying novel, delivered with maximum narrative rigour. A police diver discovers a severed human hand in Bristol's floating harbour. Shortly afterwards, another hand -- from the same victim -- is found buried underneath a restaurant. The severed hands are those of a young heroin addict who has recently gone missing from the Bristol drugs scene. A police diver, Flea Marley, finds herself joining forces with DI Jack Caffrey, recently seconded to the Major Crime Investigation unit. Jack is attempting to come to terms with the murder of his brother, but finds himself more than occupied with the details of the death of Mossy, the young heroin addict. It appears that the latter has become embroiled in a sinister black market trade stemming from Africa, where the value of human life is held at less than nothing. Jack and Flea form an uneasy alliance, tackling together a world steeped in the most appalling torture and abuse of human life. Those who have read the powerful predecessors to this novel (such as Birdman and The Treatment) will know what to expect. Mo Hayder is always reliable in delivering riveting (if deeply uncomfortable) reads. --Barry Forshaw

I normally love Mo Hayder books and I was looking forward to her latest but I was left feeling very disappointed after reading this one. The main character Jack Cafferty seems like a completely different man and the other leading character (Flea) is just weird. I found that I didn't really understand how all the characters fitted together. The `Walking Man' seemed not to be important but clearly he will be involved in the future books. I did find the topic of African Rituals very interesting and I was gripped by the scenes with Mossy in his lair. The story was easy to follow even though the timeline jumped around although I found it predictable and was not surprised by the ending. It's just frustrating because we know that Mo Hayder can do better.
