Jerry, Mr. James O. Hall wrote, "No record has been found to show that Booth was considering this scheme prior to the time he registered at the Parker House on July 26, 1864. Yet the evidence is persuasive that he left the hotel four days later for Baltimore to enlist the first two recruits into the evolving conspiracy that would ultimately take the life of Abraham Lincoln."

On July 24, 1864, Booth wrote to Isabel Sumner, "I will come at once to Boston."

So did he go to meet with Confederate agents or to see Isabel Sumner?

Good question. Do you know anymore about the note to Isabel?
My notes say that Godfrey Hyams, Jacob Thompson's courier and Luke Blackburn's plague distributor, was also registered at the Parker House when Booth was there.
