Flight of a Witch (The Felse Investigations)

When Tom Kenyon’s investigation into the disappearance of a young girl is linked to Detective Inspector Felse’s inquiry into a death, the subsequent search takes the two men along a trail of betrayal, robbery, and murder to a deadly confrontation among the ancient stones of Hallowmount

Annet Beck is hauntingly beautiful, which worries her parents so much that they guard her as closely as a prisoner . . . until the rainy Thursday in October when she disappears. Annet is last seen vanishing over the crest of the eerie Hallowmount, a hill said to be the abode of witches. Five days later, she mysteriously reappears, claiming that she was only gone for two hours.

Enchanted by her beauty, Annet’s parents’ lodger Tom Kenyon is determined to find the explanation for her disappearance: Could it be deceit, amnesia, or witchcraft? Tom’s amateur investigations lead to nowhere until Detective Inspector George Felse finds cause to connect those missing five days with his inquiry into a death.
