This last of Tey’s novels features her recurring sleuth, Inspector Alan Grant, but it isn’t much of a detective story. At a structural level, it resembles a mid-20th-century suspense movie, and indeed it may have drawn inspiration from certain classics of that genre. 
The plot unfolds like an amalgam of several Alfred Hitchcock features, including The Man Who Knew Too Much (1934), The Lady Vanishes (1938), and Shadow of a Doubt (1943). First comes the discovery on a train of a dead man by a more or less innocent bystander. Next comes a search for the meaning of some cryptic lines of verse that the victim had penned (“The beasts that talk/The streams that stand/The stones that walk/The singing sand/ . . . /That guards the way/To Paradise”)—a search that leads literally to the Scottish Hebrides and figuratively to the deserts of Arabia. Then, in the finale, comes the exposure of a villain who embodies the awesome evil that pure vanity can engender. The villain’s identity is revealed rather than detected, and in general Tey has crafted a story that appeals more to the thrill of a chase than to the pleasure of rationally dissecting a puzzle.
Yet actual thrills are few and far between. The Singing Sands, even as it follows Grant’s obsessive quest to decipher an evocative dying message, reads mainly like a meditative study of character and incident. If Tey (or a screenwriter charged with adapting her work) were to add a few scenes that involve physical danger, the result might form the basis of an excellent film—a world-weary, postwar update of The 39 Steps (the 1935 Hitchcock version). But as it is, as an achievement of the printed word, the tale offers modest fare for a reader’s imagination.
