Tidwell revisited

[Gene C]

If I recall properly, the book the Lincoln Conspiracy by David Balsiger and Chales Sellier had Herold being miss-identified as Henson.
The book became a not so great movie and is on Internet Archive - https://archive.org/details/the-lincoln-conspiracy-1977

I also recall Ray Neff being involved in the narrative before he wrote his classic book, Dark Union.
He tries to prove it was a Herold look-a-like named Henson who accompanies a Booth look-a-like, Boyd and finally are caught/killed at Garrett's farm.
