The author said that Wilkes was the head of the conspiracy, but there was someone they captured who was in on it. He alluded that they had more nefarious plans for President Lincoln, that might have included kidnapping and torture.
Never heard torture! The original plan was to kidnap him and have prisoners exchanged. No plan called for torture. Already, from what people are saying here, I’m having doubts about this book. After Lee surrendered, Booth changed the plan to assassination. There were about 5 or 6 conspirators. They were all caught except that rat John Surratt.
