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
