In the sticky summer of 1943, a secluded cottage in the Berkshires sounds just the ticket to the newly married Clara Gamadge. The resident ghost, a slender woman in a sunbonnet who died just one year ago in the cottage Clara is now renting, merely adds to the local color. It's all nothing more than a spooky game, until the woman's sister is strangled while Clara dozes in a chair by her bed. The only clue: Clara's panicked memory of a woman in a sunbonnet standing at the door. Happily, Henry Gamadge arrives in time to calm his wife and solve the mystery (though not without some stellar help from Clara!).
