“No, no. Forget that crap. He wanted to put Richard Nixon in office. And he was willing to do whatever was required to accomplish that. Hoover and Nixon went way back, to the 1960 election when Nixon lost to JFK. Bobby Kennedy, on the other hand, had treated Hoover like shit when he was attorney general. So, in May 1968 Nixon is making sober speeches about law and order to middle America, while Bobby Kennedy runs from ghetto to college campus preaching about racial equality, poverty in Mississippi, the evils of the Vietnam War, and reaching out to the Soviet Union.”

“I still don’t see the relevance to Del Payton.”

Stone looks exasperated by my slowness. “The relevance is to Leo Marston. And more important, to his father. Leo’s father was a major Mississippi power broker, a former state attorney general, just like Leo turned out to be. He was close friends with Big Jim Eastland, a well-known segregationist, head of the Senate Judiciary Committee, and J. Edgar Hoover’s number one cheerleader on Capitol Hill.”

At last the picture is coming clear.

“The sixty-eight presidential election was the second closest in history, Cage, after Nixon and JFK in 1960. In sixty-eight Nixon won by less than one percent of the vote. That’s how close it was in November. Back in May, when Del Payton was murdered, anything was possible. Mississippi was a Democratic state, but it voted strangely in presidential elections. In 1960 her electors didn’t vote for JFK or Nixon, but some guy named Byrd. In sixty-four they voted for Goldwater. In 1968 they were leaning toward—”

“Wallace,” I finish. “George Wallace.”

Stone nods. “The racist firecracker from Alabama. Wallace was running as an Independent. Leo and his father were Democrats, but they thought Bobby Kennedy was a communist. Wallace was too racist for them, and more important, they didn’t think he could win. So, they cast their lot with Nixon. Old man Marston was doing all he could to sway the movers and shakers in Mississippi to forget Wallace and vote Republican.”

“Jesus.”

“You see it now? Into this mess rides Special Agent Dwight Stone, telling J. Edgar Hoover that the son of one of Nixon’s biggest supporters is responsible for a race murder in Mississippi. Did that make the director happy? No, sir. Do you think Hoover wanted to tell his buddy Senator Eastland that the son of an old crony was going to jail for killing a nigger who got out of line? No, sir. And the thought of what Bobby Kennedy would do with that information was enough to give Hoover a heart attack. So . . . what do you think Hoover said to Leo at that meeting in Jackson?”

“I have no idea.”
