A 29-year-old man lives alone in his Glasgow flat. The telephone rings; a casual conversation, but behind this a job offer. The clues are there if you know to look for them. He is an expert. A loner. Freelance. Another job is another job, but what if this organisation wants more? A meeting at a club. An offer. A brief. A target: Lewis Winter. It's hard to kill a man well. People who do it well know this. People who do it badly find out the hard way.
