Was there an assassin on Grant's train?

[Pamela]

I'm reading Decapitating the Union now and it is a great read. John does a great job of putting forth all of the versions of various incidents that are part of the assassination story, even minor details, like the way the Lincolns and Clara Harris and her fiancé travelled to the theater. He analyzes which version is likely correct in light of all known information and details that are available to historians. It's good to bring clarity to a story that often gets pretty muddy with many slightly or greatly different versions. And I like that he described John Surratt as a "vile man"! No sugar coating of the characters.
