I thought about it. "I suppose it did. What are the Hexers? What—for the sake of argument—have they got against me?"

"The Hexers aren't human. I suppose they are extraterrestrials. No one ever told me. Maybe they are a kind of human strain that went different. I don't really know. They want different things than we do, but they can buy some of them with money, so they can be hired. People in the future hire them to hex people in the past."

"Why would anybody up ahead there with Buck Rogers want to cause me trouble? I'm dead then, aren't I?"

"Yes, you must be. It's a long time into the future. But, you see, some of my relatives there want to punish you for—it must be for killing Father. They lost out on a chain of inheritance because he died when he did. They have money now, but they are bitter because they had to make it themselves. They can afford every luxury—even the luxury of revenge."

I suppose when you keep seeing monsters and hearing yourself say things you didn't say, you can believe unusual things easier. I believed Miss Tompkins.

"It was not murder," I said. "I killed him by accident."

"No matter. They would hex you if you had hit him with a car in a fog or given him the flu by sneezing in his face. I understand people are hexed all the time for things they never even knew they did. People up there have a lot of leisure, a lot of time to indulge their every irritation or hate. I think it must be decadent, the way Rome was."

"What do you—and the machine—have to do with my hex?" I asked.

"This is the Primary Focus area, I told you. It's how the Hexers get into this time hypothesis. They can't get back into this Primary itself, but they can come and go through the outer boundary. It's hard to set up a Primary Focus—takes a tremendous drain of power. They broke through into the basement of the old house before I was born and Daddy was the first custodian of the machine. He never knew that he was helping avenge his own death. They let that slip later, after—it happened."

"Why did they come to you? Why did you help them?"
