Pru and her husband, former Detective Chief Inspector Christopher Pearse, are long overdue for a getaway. So when Pru is invited to redesign an Arts and Crafts garden in the picturesque Cotswolds, she and Christopher jump at the chance. Unfortunately, their B&B is more ramshackle than charming, and the once thriving garden, with its lovely Thyme Walk, has fallen into heartbreaking neglect. With the garden's owner and designer, Batsford Bede, under the weather, Pru tackles the renovation alone. But just as she's starting to make headway, she stumbles upon Batsford's body in the garden-dead and pinned beneath one of his limestone statues.

With such a small police force in the area, Christopher is called upon to lead the investigation. Pru can't imagine anyone murdering Batsford Bede, a gentle man who preferred to spend his time in quiet contemplation, surrounded by nature. But as her work on the garden turns up one ominous clue after another, Pru discovers that the scenery is more dangerous than she or Christopher could have anticipated.
