The assassination of Abraham Lincoln set off a hysterical burst of international conspiracy theories, with all eyes turning first to Canada--once a hotbed of Confederate plots--and then, as evidence mounted, to the Catholic Church and Rome. Now from bestselling author, Max Byrd, comes a long forgotten true story: a confidential mission to track down and capture any Europeans (and fugitive Confederates) who may have aided John Wilkes Booth. Drawn from State Department archives and personal letters and diaries, The Sixth Conspirator recounts the dramatic journey of George H. Sharpe, General Ulysses S. Grant's real-life spymaster, to three European capitals. Three people travel with him--calculating banker Daniel Keach, Sharpe's Civil War protege Quintus Oakes, and former Pinkerton agent Maggie Lawton. One step ahead of them is a mysterious Confederate courier, Sarah Slater, known during the war as "the Veiled Lady," who may or may not have been Booth's lover. Behind Sharpe's team, breathing grimly over their shoulders, are Secretary of State William Seward, brutally mutilated by the knife of one of Booth's henchmen, and the perversely vengeful, guilt-ridden Secretary of War Edwin Stanton.
