Commander Dalgliesh is recuperating from a life-threatening illness when he receives a call for advice from an elderly friend who works as a chaplain in a home for the disabled on the Dorset coast. Dalgliesh arrives to discover that Father Baddeley has recently and mysteriously died, as has one of the patients at Toynton Grange. Evidently the home is not quite the caring community it purports to be.
