If, like us, you can’t quite get enough of James L. Swanson’s MANHUNT: THE 12-DAY CHASE FOR LINCOLN’S KILLER, head to the author’s website.

There, Swanson offers a few bits of supplemental material not in his acclaimed book, including a timeline of “the chase” for Lincoln assassin John Wilkes Booth and a nearly eight-minute video of Swanson showing off pieces of his extensive collection of Lincoln memorabilia. Plus, you get to hear Swanson talk about Booth’s killer having performed a castration on himself. Ahhh, history.
