Memphis, TN – At the outset of my research, I took very seriously the idea that there might have been a conspiracy. I read all the conspiracy books, examined every angle. The only problem with the conspiracy theories that are out there, I found, is that they invariably fail the most basic test: They raise more questions than they address, they create more problems than they solve. And they're so monumentally complicated: The CIA, the FBI, the Mafia, the Green Berets, President Johnson, the Memphis Police Department, the Memphis Fire Department, the Memphis Mayor's Office, the Boy Scouts of America--everybody killed Martin Luther King! But as I got into it, it became clear that the evidence against James Earl Ray was overwhelming. He bought the rifle, the scope, the ammo, the binoculars. He checked into that rooming house three hours before the murder. He peeled out from the rooming house one minute after the murder, in the same getaway car described by eyewitnesses. He admitted to every one of these things. His only defense was that some other guy--a mysterious man he called Raoul--pulled the trigger. Well, there's not a shred of evidence that Raoul ever existed. So in Hellhound, I take the clear position that Ray did it, but I leave many doors ajar as to the question of whether he had help, whether he was working in the hope of winning bounty money, whether members of his own family abetted him. When in doubt, I generally err on the side of Occam's razor: The simplest explanation is usually the right one.
