Finn is the only son of a successful Irish doctor, Dr Malachi Finn of Killaloe, County Clare, who sends him to London to become a lawyer. He proves to be a lackadaisical student, but being pleasant company and strikingly handsome to boot, he makes many influential friends. One of them, a politician, Barrington Erle, suggests that he stand for Parliament in the coming election. At first, the idea seems absurd. Finn is supported solely by a modest allowance from his father, but a stroke of luck clears his path.
