When a teenage boy shoots a young woman dead in the middle of a busy Glasgow street and then commits suicide, Detective Harry McCoy is sure of one thing. It wasn't a random act of violence. With his new partner in tow, McCoy uses his underworld network to lead the investigation but soon runs up against a secret society led by Glasgow's wealthiest family, the Dunlops. McCoy's boss doesn't want him to investigate. The Dunlops seem untouchable. But McCoy has other ideas . . . In a helter-skelter tale winding from moneyed elite to hipster music groupies to the brutal gangs of the urban wasteland Bloody January brings to life the dark underbelly of 1970s Glasgow and introduces a dark and electrifying new voice in Scottish noir.
