Yes—critics praise it as a "first-rate nonfiction thriller" with "shocking conspiracy" details. Brad Meltzer and Josh Mensch transform obscure history into a gripping account of leadership under threat, offering fresh perspectives on Lincoln’s presidency and the fragility of democracy.

Pinkerton, founder of the Pinkerton Detective Agency, led undercover operations to infiltrate the conspirators. He disguised Lincoln, altered his travel route, and deployed Kate Warne—one of America’s first female detectives—to gather intelligence, ensuring Lincoln’s safe passage to Washington.

Like The First Conspiracy (about George Washington), this book exposes little-known historical plots through rigorous research. Meltzer’s signature blend of thriller pacing and nonfiction depth makes it ideal for fans of his political conspiracy works.

The plotters, tied to a white supremacist secret society, feared Lincoln’s antislavery stance would threaten Southern interests. Their goal was to destabilize the Union by preventing his inauguration, potentially altering the Civil War’s trajectory.

Warne, a pioneering female detective, posed as a Confederate sympathizer to gather critical intelligence. Her work exemplifies the often-overlooked role of women in 19th-century law enforcement and intelligence operations.

Lincoln’s death would have delayed or prevented his presidency, potentially allowing Southern states to solidify secession. The Union might have lacked his leadership during the Civil War, altering emancipation and U.S. history.

By detailing polarized politics and violent extremism, the story resonates with contemporary struggles to protect democracy. It underscores the enduring relevance of vigilance against ideological threats.

The authors drew from Pinkerton’s archives, historical newspapers, and government records to reconstruct events. Their reliance on primary sources ensures historical accuracy while maintaining narrative suspense.

Key themes include leadership under pressure, the dangers of political extremism, and the unsung heroes who safeguard democracy. The book also examines how secrecy and misinformation shape history.

The 1861 plot was overshadowed by the Civil War’s outbreak and Lincoln’s eventual assassination. Meltzer and Mensch revive this buried story, highlighting its significance as a precursor to national turmoil.
