Everyone knows the story of Abraham Lincoln's assassination in 1865, but there was also a plot to kill him four years earlier, while he was on his way to his first inauguration. Here the authors who chronicled a threat to George Washington's life in The First Conspiracy tell the riveting story of the white supremacist secret society who intended to ambush the President-elect in Baltimore. The heroes in this real-life political thriller include famed detective Allan Pinkerton, who infiltrated the group with undercover agents, and Kate Warne, one of the first female private detectives in America.
