Ellen laughed. “What an awful thing to fall in love with. It’s like having a passion for rats.”

“That’s what most people think,” said Hooper. “But they’re wrong. Sharks have everything a scientist dreams of. They’re beautiful—God, how beautiful they are! They’re like an impossibly perfect piece of machinery. They’re as graceful as any bird. They’re as mysterious as any animal on earth. No one knows for sure how long they live or what impulses—except for hunger—they respond to. There are more than two hundred and fifty species of shark, and every one is different from every other one. Scientists spend their lives trying to find answers about sharks, and as soon as they come up with a nice, pat generalization, something shoots it down. People have been trying to find an effective shark repellent for over two thousand years. They’ve never found one that really works.” He stopped, looked at Ellen, and smiled. “I’m sorry. I don’t mean to lecture. As you can see, I’m an addict.”

“And as you can see,” said Ellen, “I don’t know what I’m talking about. I imagine you went to Yale.”

“Of course. Where else? For four generations, the only male in our family who didn’t go to Yale was an uncle of mine who got thrown out of Andover and ended up at Miami of Ohio. After Yale, I went to graduate school at the University of Florida. And after that, I spent a couple of years chasing sharks around the world.”

“That must have been interesting.”

“For me it was paradise. It was like giving an alcoholic the keys to a distillery. I tagged sharks in the Red Sea and dove with them off Australia. The more I learned about them, the more I knew I didn’t know.”

“You dove with them?”

Hooper nodded. “In a cage mostly, but sometimes not. I know what you must think. A lot of people think I’ve got a death wish—my mother in particular. But if you know what you’re doing, you can reduce the danger to almost nil.”

“You must be the world’s greatest living shark expert.”

“Hardly,” Hooper said with a laugh. “But I’m trying. The one trip I missed out on, the one I would have given anything to go on, was Peter Gimbel’s trip. It was made into a movie. I dream about that trip. They were in the water with two great whites, the same kind of shark that’s here now.”

“I’m just as glad you didn’t go on that trip,” said Ellen. “You probably would have tried to see what the view was like from inside one of the sharks. But tell me about David. How is he?”

“He’s okay, all things considered. He’s a broker in San Francisco.”

“What do you mean, ‘all things considered’?”

“Well, he’s on his second wife. His first wife was—maybe you know this—Patty Fremont.”

“Sure. I used to play tennis with her. She sort of inherited David from me. That’s a nice way of putting it.”
