Fido, you got it. Way to go! Somewhere in my closet I have a photo of David Herold's "splendid pointer dog." That will be your prize if I can find the darn thing.
The witness was Benjamin W. Vanderpoel, a lieutenant of the 59th NY Volunteers who was an acquaintance of Booth and claimed to have seen Booth and Company at a meeting at the Canterbury Music Hall, where a woman was dancing around and "flashing her legs" on the stage - this was testimony given at the 1867 John Surratt Trial and I'll be darned if I can remember the Defense!
"The Past is a foreign country...they do things differently there" - L. P. Hartley
"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."
Hint #1: About this man William Hanchett wrote, "So far as I could tell, he never went to bed, preferring to use a cot in the room with his desk and some of his files."
