Hollis is a retired soap manufacturer, richer than Croesus and some say mad. Obsessed with amassing precious stones and bullion, Hollis chooses a strong room to deposit his dazzling hoard. But when he discovers that he’s the victim of an elaborate and enigmatic robbery, even though the room was never broken into, Dr Thorndyke is summoned to bring his unrivalled knowledge to bear on a remarkable mystery.
