Glasgow in the 1950s private investigator Lennox is keeping a low profile, enjoying a 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 at the time. 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 out there, an elusive villain who makes the Three Kings look like minnows. Lennox is going to get his fingers burnt, badly.
