Set in the Northwest territories of Canada, the latest from Kathy Reichs finds Tempe Brennan investigating a triple-infanticide and multiple murders in the cut-throat diamond mining business. Tempe is called in to evaluate the corpses of three murdered babies in Montreal, and her long-time flame Detective Ryan is charged with pursuing the likeliest suspect, their mother, a prostitute in the past, and possibly still. But when the suspect flees to Edmonton, the investigation is jarred by a sergeant in the Royal Canadian Mounted Police with whom Tempe had an ill-advised fling at Quantico over a decade earlier. Sexual tension and violence run high in this stellar new book by Reichs.
