Finding Lincon's Killer

What I am reading is "Finding Lincon's Killer".It's about how this guy is named booth and how he wants to assasinate the president.So he was about to go to Washington but then somebody tells him that the president lincon is coming to town.He also said that he was coming for a show at the theater.Later he makes a plan on how he is going to assasinate him but he has to do it fast.It is so intresting that you won't think it's history or even real.That is the book I am reading.
