Boris Vian wrote prose and poetry, worked as a journalist, wrote scripts and acted in films (a dozen and a half films, by the way), sang and composed songs (about four hundred in total). It is a rare case when intellectual prose also turns out to be funny, but this is precisely the main work of Boris Vian, “Foam of Days.” This fascinating, phantasmagorical, enchanting mystery novel is still printed all over the world in millions of copies. It is no coincidence that F. Begbeder put it in the top ten of his world literary hit parade.
