London. 1945. The capital is shrouded in the darkness of the blackout, and mystery abounds in the parks after dusk. During a stroll through Regent's Park, Bruce Mallaig witnesses two men acting suspiciously around a footbridge. In a matter of moments, one of them has been murdered; Mallaig's view of the assailant but a brief glimpse of a ghastly face in the glow of a struck match. The murderer's noiseless approach and escape seems to defy all logic, and even the victim's identity is quickly thrown into uncertainty. Lorac's shrewd yet personable C.I.D. man MacDonald must set to work once again...

When Dr Raymond Ferens moves to a practice at Milham in the Moor in North Devon, he and his wife are enchanted with the beautiful hilltop village lying so close to moor and sky. At first they see only its charm, but soon they begin to uncover its secrets - envy, hatred and malice. Everyone says that Sister Monica, warden of a children's home, is a saint - but is she? A few months after the Ferens' arrival her body is found drowned in the mill race. Chief Inspector Macdonald faces one of his most difficult cases in a village determined not to betray its dark secrets to a stranger.
