The Assassins Accomplice

Set against the backdrop of the Civil War, the book examines Mary Surratt's deep involvement in John Wilkes Booth's conspiracy, initially to kidnap and later to kill President Lincoln.

Larson draws on extensive evidence to argue Surratt's guilt, detailing her recruitment of accomplices, ferrying of weapons, hosting of plotters, and lies to investigators.

It covers her life, trial by military tribunal, and execution as the first woman hanged by the federal government, challenging prior views of her innocence.
