Under the Net by Iris Murdoch

Iris Murdoch's first novel is set in a part of London where struggling writers rub shoulders with successful bookles, and film stariets with frantic philosophers. Its hero, Jake Donaghue, is a drifting, clever, likeable young man, who makes a living out of translation work and sponging off his friends. However, a meeting with Anna, an old flame, leads him into a series of fantastic adventures.
