The protagonist of the new book is a young and very fit London cycle courier Astrid Bell, who suddenly seems to be bad news for those around her. When her neighbour Peggy Farrell inadvertently knocks Astrid from her bike, Peggy is subsequently found in an alley, savagely beaten to death. Astrid is assigned to collect a package from a well-heeled women by the name of Ingrid de Soto -- but when she arrives, Astrid discovers her in the hallway of her home, also murdered. Needless to say, the police -- not great believers in coincidence -- begin to take a very close interest in Astrid, and soon life for her and her housemates begins to turn very unpleasant, with internecine squabbling (and a burgeoning apprehension about who is to die next) poisoning once friendly relationships.

The slow and inexorable breakdown in the natural order of things is meat and drink to Nicci French, and the lengthening list of strongly written crime novels has acquired another winner with Until It’s Over. It's particularly commendable that French resolutely avoids the temptation to write about a series detective. Powerful stand-alone narratives with ordinary people at the centre are the hallmarks of a Nicci French novel -- long may they remain so. --Barry Forshaw
