Glasgow in the 1950s. Private investigator Lennox is keeping a low profile, enjoying a secret fling with the daughter of shady bookie and greyhound breeder MacFarlane. When MacFarlane is found bludgeoned to death, Lennox is a suspect. Luckily, he has a solid gold alibi: he was in bed with the victim’s daughter.

Lennox is quickly drawn into hunting the killer. It turns out MacFarlane was into some seriously dodgy stuff. One of Glasgow’s notorious Three Kings, crime boss Willie Sneddon, is involved, and he’s not a man Lennox wants to cross. But there’s an even bigger player lurking in the shadows, and it looks like Lennox is going to get his fingers burnt - badly.
