Was there an assassin on Grant's train?

[RJNorton]

Pam, I can add Mike Kauffman's opinion on the Father Menu letter. I had written Mike about this back in 2006, and Mike replied:

"If Father Menu wrote to Weichmann just after the so-called kidnap attempt, his letter would have arrived about March 20 or 21. John Surratt was out of town at the time, so that means it was most likely Mary Surratt who intercepted the letter and turned it over to Booth (perhaps indirectly through John, later in the week.) In her defense, it could be said that her motive was to warn her son that he ought not to trust his old friend. Either way, it was not just Weichmann who betrayed Mrs. Surratt; that was a two-way street."
