Summer 1911. A scorching heatwave engulfs the quiet town of Littleton Cotterell and brings about an unusually early harvest. The villagers are thrilled, but events quickly turn sour when one of them turns up dead in an apple orchard, stabbed through the heart. Amateur sleuth Lady Hardcastle and her trusty lady’s maid, Flo, suddenly have a juicy case on their hands. Might the mysterious stranger they recently met in the village be to blame? When a second cider-related murder takes place, it quickly becomes clear that there’s more to these mysterious deaths than meets the eye. The daring duo uncover whispers of an ancient order and moonlit rituals. And evidence points to a macabre secret in the village stretching back years. A secret someone will do anything–anything at all–to keep hidden. Something is rotten, that’s for sure. With the local constabulary baffled, Lady Hardcastle and Flo must use all their powers of wit and whimsy to get to the bottom of the dastardly deed. But can they catch the killer before any more people drop dead?
