On the spur of the moment, Livingston decided he had to kill Leebove, now. He went through the Doherty Hotel lobby and up to his room. He took a gun from a trunk. It had five bullets in it. He put the gun in his coat pocket and went back downstairs, reentering the lounge unnoticed by Leebove, who had his back to the entrance from the lobby. Livingston sat another three or four minutes, thinking over what he was going to do. Then he got to his feet. Delusional from drink and stress, his eyes darted about the room. He thought that he saw Leebove glancing up at him. To Livingston, it looked like Leebove was trying to get the jump on him. Nervously jerking his hand in and out of his coat, he took a few short steps to the booth where Leebove sat. He halted directly in line with Leebove, who was turned slightly as he talked with a friend. Blinded by rage, fear, and resolve, Livingstone saw only Leebove as he pulled the .38 revolver from his coat pocket and took aim at the man who had once been his close friend... Mystery Man is the story of Isaiah Leebove, Jack Livingston, and a cast of innocents and not-so-innocents. Oil barons from Oklahoma like Nathan Livingston and Henry Sinclair, New York gangsters like Arnold Rothstein and "Legs" Diamond, Detroit's Purple Gang, even Charles Lindbergh's baby all figure in the unfolding drama that ultimately played out in Clare in the days of Michigan's oil boom. A personal grudge led to Leebove's murder—or was it the perfect gangland slaying?
