Booth's Mental health

[RJNorton]

Just curious - does anyone know for certain where Booth spent the night of the 13th? I had assumed he spent it in his room at the National Hotel, but today I noticed that on p. 67 of A. Lincoln: His Last 24 Hours W. Emerson Reck wrote:

No one seemed to know where Booth spent the night of April 13. When three men (presumably Herold, Paine, and Atzerodt) sought Booth at the National Hotel on the morning of April 14, it was discovered that the bed in his room, No. 228, had not been touched. Somewhere, however, he had written at 2:00 A.M. a short letter to his mother, in which he excused his brevity with "am in haste."

I then checked Art Loux's book, and he has no definitive answer but gives several possibilities. One of the possibilities Art mentioned is that Booth did not sleep at all ("the prospect of the planned murder may have kept him awake") but walked about the city seeing the Grand Illumination and then possibly spending time with Lucy Hall and/or Ella Starr. Art writes that Booth may have then "returned to his hotel room and slept on top of the bed covers."

Does anyone have any thoughts? Thanks!
