I may be a little bit biased, for example this
is my favorite t-shirt, but I loved this book. From start to finish, it's a riveting, narrative historical account of the assassination and its aftermath. Even John Wilkes Booth becomes a sympathetic human being in Swanson's care. These aren't just dry, historical figures anymore. By putting them in the context of a story -- even fictionalizing/speculating a little bit -- he makes them real people.
