Booth in Boston April 1865

[Gene C]

Why? I think the hotel register, dated April 5 with Booth's signature, is fairly strong evidence, especially when combined with the letter.

What I don't think is supported by any contemporary evidence is the identity of Lucy as the "lady" with whom Booth checked in.

That seems like a foolish thing to do for someone involved with a senators daughter. Why go to such a public place for a rendezvous?
If he really was in Newport it seems that during these final few week Booth seems to frequently let his passion rule his thoughts.
