Booth's visit to the Surratt Boarding House after the assassination

[RJNorton]

Kate Larson asked a question that I don't think anyone answered. She said, "However, that doesn't preclude Booth coming - could the pistols have been stashed outside?"

If the answer is "yes," then this would explain Weichmann not being aware of a possible 10:30 stop by Booth. Could Mary have hidden Booth's stuff under the stairway after the 9:00 visit? Was it dark under there? Was there a dark alley in back of the boardinghouse?
