When a body is found in the woods, Detective Thomas Lang assumes it's a tragic one-off. At least until he reads the letter found with the victim. Then another body appears. And another. Each one is missing a shoe, and each one is found with a letter from the killer.
As the investigation continues, Lang's partner starts to unravel, hiding secrets he refuses to share, ones that could break the case wide open. But when the trail points to a mystery from a decade ago, the truth begins to close in.
By then, the bodies are piling up, and it may be too late. The killer's motive is vengeance, and their last target is closer than Lang could ever imagine.
