Book excerpt: On November 22, 1963, a murder was committed in Dallas, Texas. Nearly 80 percent of the American people don't believe the victim was killed by a lone gunman. The House Assassinations Committee determined it was the work of "a conspiracy," yet no conspirators were ever identified or brought to justice. For more than forty years the case has remained unsolved—until now. Mark Fuhrman has cracked some of the best-known, most puzzling crimes in American history. In A Simple Act of Murder, he investigates the tragedy that rocked a nation: the assassination of President John F. Kennedy. Cutting through the myths and misinformation, Fuhrman focuses on the hard evidence, unveiling a major clue that was ignored for more than four decades—a breakthrough that will change the ongoing debate forever. Once you read this book, you'll know definitively who killed JFK.
