Poison and Herold

[RJNorton]

Vaughan Shelton, author of Mask For Treason, claimed that David Herold tried to poison John Wilkes Booth. He claimed the field glasses Mary Surratt delivered to John Lloyd contained poison that Herold put into Booth's whiskey. According to Shelton, Booth drank deeply from the bottle of liquor brought to him by Herold at Lloyd's. The slow poisoning of Booth went on for some time.

So did Herold try to poison Lincoln? Booth? Both? IMO, neither story is true, although Herold may have actually delivered a bottle of castor oil to the White House while working at Thompson's drug store.
