Bruce Attleton dazzled London’s literary scene with his first two novels, but his early promise did not bear fruit. His wife, Sybilla, is a glittering actress, unforgiving of Bruce’s failure, and the couple lead separate lives in their house at Regent’s Park. When Bruce is called away on a sudden trip to Paris, he vanishes completely until his suitcase and passport are found in a sinister artist’s studio, the Belfry, in a crumbling house in Notting Hill, and Inspector Macdonald must uncover Bruce’s secrets. This intricate mystery from a classic writer is set in a superbly evoked London of the 1930s.

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 to unravel this near-impossible mystery.
