“Stan’s gotten far too much credit,” says veteran comics writer Gerry Conway, who’s known Lee since 1970. “People have said Stan was out for No. 1, and to a very large degree, that’s true. He’s a good guy. He’s just not a great guy.”

“Unfortunately, from day one, Jack was doing part of Stan’s job, and Stan was not doing part of Jack’s job,” says comics historian Mark Evanier, who worked as Kirby’s assistant and has worked on and off with Lee since the 1970s. “When you talk to Stan Lee, when he turns the Stan Lee act off, he’s a very decent human being who is chronically obsessed with himself. He’s very insecure. Those of us who have trouble being angry for some of the things that happened, it’s because we saw the real human being there at times.”

“It’s one of those things where you sit down and you say, ‘You gotta be forgiving of your parents,’” says artist Colleen Doran, who drew Lee’s new memoir. “I don’t know of anyone who knows Stan and doesn’t love him, even if they hate things he’s done.”

The couple admitted manslaughter, but not double murder. They said 63-year-old Patricia had shot William, 85, during a late-night row. In their version of events, Patricia had then turned on Susan, saying she was having an affair with Christopher, taunting and provoking her into turning the gun on her mother. Susan told the police she’d been sexually abused by her father until she was 11, and that her mother had been complicit. The couple said it was a crime of passion and claimed that Susan had acted alone. She told Christopher only a week after the shooting, they said, when they returned to Mansfield from their home in Dagenham, ate fish and chips, watched the Eurovision song contest, and got up at 2am to bury the decomposing bodies.

“They’d had 15 years to prepare a story that would bring them the least amount of time in prison,” DCI Rob Griffin, who led the case against the couple, tells me. It was his job to prove this was a calculated double murder, motivated by greed and deserving a long stretch in jail. But proving anything in a case this historic is a challenge: there were no phone records, no CCTV, no emails for him to trawl through (“The footprints people tend to leave behind nowadays weren’t there for us”). So Griffin turned to what he calls “old-fashioned detective work”: tracing relatives and neighbours from 1998 to try to piece together what had happened.

The team found what they were looking for during one of the Predator’s very first split operations missions in early September 2000. Swanson was circling over Tarnak Farms, a walled compound near the Kandahar airport where bin Laden-or UBL as the team called him, referring to the alternative spelling, Usama-was thought to be living. Jeff Guay, an Air Force master sergeant on the team, was controlling the drone’s camera. Sure enough, a man in white, surrounded by an entourage, soon emerged on their screens.

“When UBL walked out of that one building,” Swanson says, “the way he appeared much taller than everybody, the people were deferential around him, the way he was dressed, Jeff and I just looked at each other and it’s like, ‘Yeah, that’s got to be him.’” Swanson assumed a cruise missile would be dispatched in the direction of bin Laden while the Predator loitered overhead to make sure he stayed put. The team had been instructed to continue circling for as long as necessary, even if that meant running out of fuel and crashing.

But for reasons obscure to the team, no strike was ordered. With Swanson gripping his joystick, unable to do anything but stare, America’s final chance to kill Bin Laden before September 11 slipped away.
