IN 1861, AMERICA’S GREATEST DETECTIVE SAVED THE LIFE OF ABRAHAM LINCOLN. THIS IS HER STORY. America is at a crossroads. Secession is spreading. And the nation’s newly elected president is the target of a conspiracy to assassinate him and trigger a Civil War. The safety of Lincoln and his family—and the future of the American experiment—hinges on the success of a new kind of lawman, known by a word still novel in the culture of the time: detective. But there was only one who would prove to be up to the task—an individual whose extraordinary cleverness and resourcefulness would alter the course of history from deep within the shadows of domestic spycraft. Her name was Kate Warne. This is the story of America’s first female detective, a trailblazing working woman trying to make a living and do some good in a tumultuous, sexist age, and whose mysterious life and tall tale exploits are truly the stuff of legend. Eisner and Emmy Award–winning writer Jeff Jensen (Green River Killer: A True Detective Story, HBO’s Watchmen) and acclaimed artist George Schall (Made in Korea) present the stunning tale of a real-life hero who shaped the course of American history.
