It's November 1932, and the peaceful village of Dovecote Hatch is still reeling from the recent murder at Mullings, country estate of the wealthy Stodmarsh family. Now it's about to be rocked by news of another violent demise. When the body of mild-mannered Kenneth Tenneson is found at the foot of the stairs in his home, the coroner's inquest announces a verdict of accidental death. However, Florence Norris—the quietly observant housekeeper at Mullings—suspects there may be more to the story than a fall. Florence's suspicions of foul play would appear to be confirmed when a second will turns up revealing details of a dark secret in the Tenneson family's past. Determined to find out the truth about Kenneth's death, Florence gradually pieces the clues together—but will she be in time to prevent a catastrophic turn of events?
