Enid Jennings, a retired headmistress and an embittered war widow, has a talent for causing conflict and distress wherever she goes. When Enid's daughter sees her vanish into thin air, she is widely assumed to have been mistaken or to have lost her mind – or worse, to have committed an act of foul play. Enter Father Gabriel. Working on the principle that some stories are too strange to have been made up, the priest sets out to discover the whereabouts of the missing woman. With help from the town's physician, and hostility from the irascible Inspector Applegate, Father Gabriel delves into Enid Jennings' past, and he digs up the recent past of the whole village during the days of the Phony War, when invaders lay in wait across the Channel and crimes were just a little easier to hide.
