The year is 1880, the place San Francisco. Intelligent, outspoken Sarah Woolson is a young woman with a goal and the fortitude to achieve it. She has always dreamed of becoming a lawyer. The trouble is, everyone believes women belong in the home---that it is not only unnatural, but against God's will for them to seek a career.

When Sarah finagles an interview with one of the city's most prestigious law firms, no one thinks she has a prayer of being hired. Except Sarah. Using her brains and a little subterfuge, she not only manages to become the firm's newest (and only female) associate attorney, she also acquires her first client---a lovely young society matron suspected of brutally stabbing to death her wealthy but abusive husband. Sarah is sure of her client's innocence, but the revelation of the woman's secret lover may make that innocence impossible to prove.

When four more victims fall prey to the killer's knife, Sarah fears she has bitten off more than she can chew. Bucking her boorish employer and the judicial system, Sarah finds herself embroiled in shady legal maneuvers, a daring Chinatown raid, and a secret and very scandalous sex club in this irresistible blend of history, romance, and murder.
