"Signet historical novel"-- Spine.

"Bounty hunter John Tone is good at his job. Some would say ruthless. If there's killing to be done, he shows no mercy. In another time, far across the ocean, Tone lost the only person he's ever loved--and he's been dead inside ever since. That's the hand fate dealt him, and he'll play it out. But then a powerful criminal from San Francisco's notorious Barbary Coast makes him an offer he can't refuse, and Tone has to draw out six of his client's worst enemies--making himself a target for the men he's been hired to kill. Against those odds, Tone knows he may be loading the six chambers of his Colt for the last time."--p.[4] of cover.
