Pinkerton Agent John Yancey is hired by Noah Harper to find his half-sister, Cecelia Powell, who he claims stole part of his inheritance.

An agent who always gets his man, or woman, Yancey tracks Cecelia to San Francisco, but as he gets to know her, he starts to wonder if his client has been completely forthcoming with him.

But he's contracted to do a job, so he reports to Harper where she is.

Soon Harper arrives in San Francisco from Boston, and Yancey learns who the real villain is.

At the same time, he finds himself developing strong feelings for Cecilia.

"Written in the traditional style of the western with the taciturn, honor-bound hero who protects the weak and punishes evil-doers, this book will delight fans of the western genre."
