Dr. David Hunter should be in London with the woman he loves and a past he can’t quite shake off. Instead, as a favor to a beleaguered cop, Hunter travels to a remote island in the Outer Hebrides to inspect a baffling set of remains. A forensic anthropologist, he has seen bodies destroyed by all forms of violence, but even he is surprised at what he finds: human remains burned beyond recognition—all within the confines of an otherwise undamaged, unoccupied cottage. Local police want to rule the death accidental. But Hunter’s examination of the victim’s charred skull tells him that this woman, no doubt a stranger to the close-knit island of Runa, was murdered by someone nearby.
