"Rely on Psmith" is a novel full of playful humor about the adventures of a high-society loafer who periodically tries to do something useful for society. This time, Psmith takes on a role completely unexpected—even for himself: he becomes a private detective and investigates an astonishingly ridiculous case of a theft of the priceless necklace of Lady Constance Cibble.
Everyone is a suspect—even… Psmith himself!
