The author of "Forty Words for Sorrow"-winner of Britain's Silver Dagger Award-returns with a crime thriller challenging our most cherished belief: that, in fiction, there is no such thing as the perfect crime. The small city of Algonquin Bay in northern Ontario: A freak warm front has moved in, making it feel like April and rousing hungry bears from hibernation. So when Ivan Bergeron's dog brings him the chewed-off arm of a white male, it's assumed the victim met a natural if ugly end. Except, as it turns out, the owner of the arm was dead before the bears got to him. A second victim is found: a woman, apparently raped. There has to be a connection-two bodies abandoned in the woods within days of each other can't be a coincidence. Then police records reveal a long-unsolved murder with the same MO: a woman found in the woods, seemingly raped. It isn't long before homicide detectives Delorme and Cardinal are led back thirty years to another unsolved murder, this one linked to Quebec terrorists. Logic suggests the Algonquin Bay murders are connected to this case. Evidence is less convincing. And somewhere, a murderer-smart and powerful-is walking free.
