Stark Contrasts (An Adam Stark novel Book 1)

DI Adam Stark is a cop from a small, Scottish town working in the biggest of all English cities – London. He’s been seconded to a specialist murder squad, but he’s not convinced the rat-race suits him.
Meanwhile, a concerned citizen has also had enough of the inconsiderate people around them and decided it’s time to teach them some lessons … forcefully.
As punishments escalate in severity, and the press make a champion of this anti-hero, Stark is trying to make sense of what’s going on. Random, unconnected victims, excessive retribution, red herrings, kidnap, mutilation, mistaken identity, gangsters, revenge and murder: things are getting totally out of hand.
Stark needs to stop this sociopath with a social conscience, but the case is so bizarre, it might just be running away from him.
