In page Boris Vian:

"

Frustrated by the commercial failure of his works, Vian vowed he could write a best-seller and wrote the hard-boiled novel I Spit on Your Graves (J'irai cracher sur vos tombes) in only 15 days. The book was ascribed to a fictitious American writer, Vernon Sullivan, with Vian credited as translator. Vian persuaded his publisher friend Jean d'Halluin to publish the novel in 1947. Eventually the hoax became known and the book became one of the best-selling titles of that year. Vian wrote three more Vernon Sullivan novels from 1947 to 1949.
