Decline and Fall : Evelyn Waugh

"Paul Pennyfeather, innocent victim of a drunken orgy, is expelled from Oxford College, which costs him a career in the church. He turns to teaching, frequently the last resort of failures, and at Llanabba Castle meets a friend, Beste-Chetwynde. But Margot, Beste-Chetwynde's mother, introduces him to the questionable delights of high society. Suddenly, and improbably, he is engaged to marry Margot. Just as they are about to say "I do, " Scotland Yard arrives and arrests Peter for his involvement in Margot's white slave-trading ring."--Amazon.
