When an old school chum of Watson (Nigel Bruce) is slain─seemingly over his possession of one of three innocuous, cheaply-made music boxes─Holmes (Basil Rathbone) goes on a peril-filled pursuit of the remaining knickknacks, and strives to crack their lethal secret. The last of the fourteen Rathbone-Bruce Holmes entries also stars Patricia Morison, Edmund Breon, Frederick Worlock. 72 min. Standard; Soundtrack: English.
