The Goldsboro bomb that almost detonated was known as Weapon No. 1. As the plane was spinning and breaking apart, the centrifugal forces pulled a lanyard in the cockpit–and that lanyard was what a crew member would manually pull during wartime to release the bomb. This hydrogen bomb was a machine, a dumb object. It had no idea whether the lanyard was being pulled by a person or by a centrifugal force. Once the lanyard was pulled, the weapon just behaved like it was designed to.

The bomb went through all of its arming steps except for one, and a single switch prevented a full-scale nuclear detonation. That type of switch was later found to be defective. It had failed in dozens of other cases, allowing weapons to be inadvertently armed. And that safety switch could have very easily been circumvented by stray electricity in the B-52 as it was breaking apart. As Secretary of Defense McNamara said, “By the slightest margin of chance, literally the failure of two wires to cross, a nuclear explosion was averted.” That’s literally correct, a short circuit could’ve fully armed the bomb.

Q: Do you think much about what your legacy will be?

King: No, not very much. For one, it’s out of my control. Only two things happen to writers when they die: Either their work survives, or it becomes forgotten. Someone will turn up an old box and say, “Who’s this guy Irving Wallace?” There’s no rhyme or reason to it. Ask kids in high school, “Who is Somerset Maugham?” They’re not going to know. He wrote books that were bestsellers in their time. But he’s well-forgotten now, whereas Agatha Christie has never been more popular. She just goes from one generation to another. She’s not as good a writer as Maugham, and she certainly didn’t try to do anything other than entertain people. So I don’t know what will happen.

I can’t pin down exactly what she did with what ingredients. I can’t even be sure that she really did the things I think she did. All I have, really, are pieces of circumstantial evidence and hunches that have coalesced over the years. In my narrative of suspicions, she preferred to use vitamin A (which can cause sleepiness, blurred vision, and nausea, among other things), then she used laxatives, and then, as she got older and lazier, she moved on to prescription drugs.

Grandma never cooked the same thing twice, and her creations were greasy beyond belief and usually really weird. For example: chicken baked with apricots and canned tomatoes, or mixed-up ground meats with prunes, or pickled things. She was infamous at the local grocery store. They saved the shark livers for her.
