One gunshot. One assassin hell-bent on killing ‘a tyrant’, as he called the 16th president of the United States. And, in one moment, history was forever changed. It was the event that shocked America: on the evening of April 14, 1865, just days after the fall of the Confederate capital of Richmond, Virginia, Southern sympathiser John Wilkes Booth assassinated President Abraham Lincoln – the first killing of a US president. Killing Lincoln is the dramatic story behind the assassination, a true historical thriller that unfolds from the conspiracy to the assassination, and concludes with perhaps the greatest manhunt in US history.
