1870’s San Francisco is set to explode in violence! Gunslinger Matthew Slade rescues a little girl from an attempted kidnapping. Now the Chinese tongs that run the city want her back – and Slade dead.

San Francisco’s a boomtown awash in money, with Victorian-style bawdy houses and a loose sense of the law. Enter Matthew Slade. Formerly the Pinkerton Detective Agency’s best investigator, tracker, and gun-hand.

Upon his arrival, Slade rescues Mai Lee, a little Chinese girl, from a pair of thugs intent on kidnapping her. The girl’s wanted by Huang Sun, the leader of the dominant tong – a crime syndicate that runs opium dens, fan-tan parlors, and prostitution in the city.

Slade can’t walk away, even if he wanted to. His first paid job as a free agent is to keep Mai Lee out of Sun’s hands – no matter the cost!

But how can a gunslinger used to the open plains and prairies of the West deal with the criminal underworld of a crowded metropolis? Even with the help of new allies and the backing of a pair of bawdy-house madams, his odds are long at best.
