For nearly 150 years, one question remains unanswered in the events surrounding the assassination of Abraham Lincoln: Was Samuel A. Mudd, the physician who set the broken leg of John Wilkes Booth, guilty or innocent of participating in the conspiracy to murder the president?Featuring a new introduction and epilogue, this well-researched and unbiased account of Mudd's testimony, trial, and imprisonment remains the gold standard on the topic more than forty years after it was first published.So, did Dr. Mudd merely answer the call of duty when an injured man appeared on his doorstep, or was he a wily co-conspirator who avoided the death penalty? Hal Higdon takes an objective stance and allows the reader to decide.
