Dan Starkey is a young journalist in Belfast, who shares with his wife, Patricia, a prodigious appetite for drinking and dancing. Then Dan meets Margaret, a beautiful and apparently impoverished student, and things begin to get out of hand. And then, terrifyingly, Margaret is murdered. Is it because of her liaison with Dan? Is it because she was not exactly who she claimed to be? Is it the IRA? A Protestant extremist group? A jealous lover? Before long, Dan is a target himself, running as fast as he can in a race against time to crack the mystery and save his marriage.
