MacKay's book is about a hired killer, Calum McLean, who's almost autistically meticulous in his methods. The book is also about his target, a small-time drug dealer whose name is given out in the title. He leads a boring life with a younger woman who still wants to party and drink all night. There's lots of intriguing melancholy here.
The first half of the book is quite good. MacKay writes short, somewhat repetitive sentences, and their rhythm grabs you. But then after the target's been hit, the novel bogs down for some reason or another, even though there's a surprise twist and an open ending that comes as a bit of a shock. I can recommend the book, though it wasn't totally satisfactory.
