Roald Dahl's first-ever novel presents the scurrilous memoirs of that delightful old reprobate from "Switch Bitch", Oswald Hendryks Cornelius - connoisseur, bon vivant, collector of spiders, scorpions, odd walking sticks, lover of opera, expert on Chinese porcelain, and without doubt the greatest fornicator of all time. In this delightful picaresque story, it is revealed how Uncle Oswald first achieved great wealth - all thanks to the Sundance blister beetle, which when ground to powder has the most electrifying aphrodisiac qualities. It is 1919 - armed with the powder and aided by the beautiful amoral Yasmin how comely, Oswald begins an audacious commercial enterprise which involves seducing the most famous men in Europe - from crowded heads to Bernard Shaw and Marcel Proust.
The nameless narrator has revealed snippets of the lovable, lascivious Uncle Oswald's life in other collections, but this is the only novel--brief though it is--dedicated solely to the diaries of "the greatest fornicator of all time." Inspired by stories of the aphrodisiac powers of the Sudanese blister beetle, the palpable seductiveness of the lovely Yasmin Howcomely, and the scientific know-how of Professor A. R. Woresley, Uncle Oswald anticipates the concept of the Nobel sperm bank by some 40 years, flimflamming crowned heads, great artists, and eccentric geniuses into making "donations." The life of a commercial sperm broker has a few surprises even for a sophisticated bon vivant, and Dahl manages his signature sting-in-the-tail ending even in one of his lightest comic works.
