A former thief turned private detective is drawn into a deadly web of murder, drugs, and gang wars, forcing him to confront his darkest demons to survive.

Having tried his hand at medicine, pickpocketing, and good old-fashioned thuggery, Seamus Caron has finally settled into life as a private detective, hunting down lost money and wandering husbands. It’s not glamorous work, but it pays the bills and provides a steady supply of fistfights for entertainment. The job also keeps him close to his best friend, Sandra Blair, a homicide detective for the Toronto Police. But when she calls in a favor on a murder case, Seamus realizes that the victim is a notorious mob lawyer, putting an end to what little stability and safety he’d managed to scrape together.

Seamus must find the killer before the murder sparks an all-out gang war. Luckily, he’s got help — a confidence man turned barman, the finest cook in Little Chinatown, and Maxwell Moscovitz, his new secretary. She has the mental sharpness and moral flexibility for the job, but she also has a few secrets of her own.

Seamus begins to suspect a connection between the murder and a new drug on the street known as Platinum, which promises obscene profits for its suppliers, euphoria for its users, and a shockingly high death rate. As he investigates suspicious overdoses, Seamus can’t help hearing echoes of his past and the tragedy he’s spent 20 years trying to forget. Caught between the police, the mob, and an anonymous killer, Seamus will need to face his demons, or he just might lose it all.
