Dame Beatrice receives a letter from her grandnephew, Denis Bradley, and relates its contents thusly to Laura over breakfast: "Denis has joined a friend named Tom Richardson for a fortnight's holiday. He was late getting to the hotel and the friend slept in a small tent until Denis arrived. A dead man was found in the tent one night. Richardson recognised him, but did not tell the police so. However, by the time the police arrived at the tent, the body had been exchanged for another which Richardson did not recognise. Now he and Denis have discovered the first body. They want us to go along and look into the matter." Look into the matter they do, and it's soon discovered that Tom Richardson, a track runner, not only knew one of the dead men but had quarreled with him on one blackmail-tinged occasion. How and why the rival athlete's body had gotten into Tom's tent, and why it was then exchanged for a second dead man, are indeed mysteries best left to the elderly sleuth. What she discovers involves an improbable mix of athletics clubs, absentee landowners, New Forest ponies, and some vague form of national/international intrigue, the undertaking of which perhaps only Dame Beatrice truly understands.
