Unknown Pleasures by Jason Cowley
Joshua Winter returns to England from Canada, where he has been living since his father disappeared twelve years earlier. He is in London ostensibly to take up a job, but really he is eager to discover the truth about his father. Soon he is drifting as his search carries him deeper into a twilight world of lurid motivation and degraded aspiration. It unwittingly carries him, too, straight into a trap. So begins a trail of murder and deception.
