Eva is excited for a visit from her sister Alice, who lives in Suffolk with her husband and three children. But when Alice arrives alone, desiring a break from her family, Eva becomes concerned. Her dismay deepens as Alice starts spending time with a former beau, Keenan Ripley, who owns the nearby pear orchard. At the same time, Phoebe's sister Julia, now a widow and pregnant, is in a fretful state, and Phoebe struggles to be helpful to her.

When Keenan's brother Stephen, the new head gardener at the Renshaw estate, Foxwood Hall, is found impaled by a pair of hedge clippers, the police-including Eva's beau, Constable Miles Brannock-suspect his closest kin. Stephen had been eager to sell their orchard to an American developer, but Keenan had fiercely resisted. A table set with two teacups and scones suggests Keenan had company the morning of the murder-and Eva fears her sister was with him.

If Alice were to provide Keenan with an alibi, her reputation and marriage would be ruined. She denies being there but is clearly withholding secrets, much to Eva's consternation. Now, to protect her sister, Eva and Phoebe set off to expose the gardener's real killer, putting their own lives at risk . . .
