Miss Porterfield meets Booth

[LincolnMan]

Article: Lincoln's Jesse W. Weik Part 2 by Glenn Tucker in the Summer 2016 The Lincoln Herald- a good read with many accounts of Lincoln and related stories. Among them is the account of a Miss Porterfield who had witnessed the assassination. According to her, she had met Booth by chance on the street April 13th. There was conversation. He seemed upset. She said she "felt something was wrong with the man" and that she detected "an irrationality."
She recounted that Booth asked her: "Don't you study Latin at school?" She replied that she did. "Then tell me this:is tyrannis spelled with two n's or two r's?"
Interesting question by Booth. Obviously, he had been planning on what he would proclaim to the audience after striking Lincoln?
