A classic mystery novel featuring Hanshews best-known creation, the consulting detective Hamilton Cleek, known as the man of the forty faces for his incredible skill at disguise.

Cleek is the central figure in dozens of short stories that began to appear in 1910 and were subsequently collected in a series of books.

Collection of several short mysteries, starring consulting detective Hamilton Cleek and his incredible skills at disguise with the assistance of his cockney assistant Dollops. Cleek is poacher-turned-gamekeeper, a master criminal who decides to turn straight and work for Scotland Yard after being stricken by the sight of a lovely, innocent young woman whose jewels he was about to pinch. Told as a fairly continuous narrative, held together by the underlying thread of Cleeks efforts to redeem himself and thus gain the affection of the woman with whom he has fallen in love. There is also another underlying thread concerning Cleeks erstwhile accomplice, Margot, and her present accomplice, Merode, as Cleek occasionally finds himself foiling their plans. Each one of these stories is a romp, some more successful than others.

Noah, inżynier geolog pochodzący z wioski przy fiordach, gdzie miał miejsce wypadek, powraca w rodzinne strony z misją.
