British author Booth's fifth crime novel (after Blind to the Bones
) is as dark and winding as the labyrinth of caves below its Derbyshire setting. In 1990, Det. Constable Ben Cooper's father arrests Mansell Quinn for the brutal murder of his lover. Thirteen years later, Quinn disappears upon his release from prison, his ex-wife is immediately slain, and another murder soon follows. Convinced they're facing a revenge spree, the police mount a manhunt, probing physical clues and the messy web of relationships that Quinn has not quite left behind. The deeper Cooper and his colleagues probe, the more convinced Cooper becomes that Quinn was innocent of the original crime, a belief that deepens his sense that as the son of the arresting officer, he's personally at risk. Though the pace and focus falter slightly toward the end, this is intelligent, suspenseful reading that should continue to build Booth's U.S. audience. A master of psychological suspense, Booth hauntingly evokes the ambiguities of place and the enduring complexity of human relationships. (Aug.)
