Assassination Trivia

[AussieMick]

I dont want to bring up red herrings but this Charles Selby ... I see that he's been mentioned before on this forum . I havent read all the posts but there doesnt seem to be a lot about him.
A google seems to only point to a Charles Selby who wrote (or produced) The Marble Heart, the play where Booth seemed to make nasty faces at Lincoln when he was in the audience.
But that Selby died in 1863 in London.
