From Devon With Death

When Juno Browne finds a life-sized effigy floating in the River Ashburn, a note attached claims it as the work of Cutty Dyer, Ashburton's mythical blood-drinking demon. But despite Juno's instinct that this is a sign of trouble ahead, the police dismiss her find as a practical joke. Then the body of a woman is discovered by the river and it becomes clear that a killer has taken on Cutty's identity.
