November, 1932. Still reeling from the recent murder at Mullings, country estate of the wealthy Stodmarsh family, the peaceful little village of Dovecote Hatch is about to be rocked by news of another violent death. When mild-mannered Kenneth Tenneson is found dead from a fall down the stairs at his home, the coroner’s inquest announces a verdict of accidental death. Florence Norris, however – the quietly observant housekeeper at Mullings – suspects there may be more to it than that.

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?
