"Jean will be ducking inside for this demonstration," I said. "You wouldn't want to be outside unprotected when the lure goes off."

"What's in it?" somebody called out.

"Triceratops blood. We're hoping to call in a predator -- maybe even the king of predators, Tyrannosaurus rex himself." There was an appreciative murmur from the diners. Everybody here had heard of T. rex. He had real star power. I switched easily into lecture mode. "If you dissect a tyrannosaur, you'll see that it has an extremely large olfactory lobe -- larger in proportion to the rest of its brain than that of any other animal except the turkey vulture. Rex can sniff his prey" -- carrion, usually, but I didn't say that -- "from miles away. Watch."

The lure went off with a pop and a puff of pink mist.

I glanced over at the de Cherville table, and saw Melusine slip one foot out of her pump and run it up Hawkins' trouser leg. He colored.

Her father didn't notice. Her mother -- her stepmother, more likely -- did, but didn't care. To her, this was simply what women did. I couldn't help notice what good legs Melusine had.

"This will take a few minutes. While we're waiting, I direct your attention to Chef Rupert's excellent pastries."

I faded back to polite applause, and began the round of table hopping. A joke here, a word of praise there. It's banana oil makes the world go round.

When I got to the de Chervilles, Hawkins' face was white.

"Sir!" He shot to his feet. "A word with you."

He almost dragged me away from the table.

When we were in private, he was so upset he was stuttering. "Th-that young woman, w-wants me t-to ..."

"I know what she wants," I said coolly. "She's of legal age -- make your own decision."

"You don't understand! I can't possibly go back to that table." Hawkins was genuinely anguished. I thought at first that he'd been hearing rumors, dark hints about his future career. Somehow, though, that didn't smell right. There was something else going on here.

"All right," I said. "Slip out now. But I don't like secrets. Record a full explanation and leave it in my office. No evasions, understand?"

"Yes, sir." A look of relief spread itself across his handsome young face. "Thank you, sir."

He started to leave.

"Oh, and one more thing," I said casually, hating myself. "Don't go anywhere near your tent until the fund-raiser's broken up."

The de Chervilles weren't exactly thrilled when I told them that Hawkins had fallen ill, and I'd be taking his place. But then I took a tyrannosaur tooth from my pocket and gave it to Philippe. It was just a shed -- rexes drop a lot of teeth -- but no need to mention that.

"It looks sharp," Mrs. de Cherville said, with a touch of alarm.

"Serrated, too. You might want to ask your mother if you can use it for a knife, next time you have steak," I suggested.

Which won him over completely. Kids are fickle. Philippe immediately forgot all about Hawkins.

Melusine, however, did not. Eyes flashing with anger, she stood, throwing her napkin to the floor. "I want to know," she began, "just what you think you're -- "

Fortunately, that was when Satan arrived.

The tyrannosaur came running up the hillside at a speed you'd have to be an experienced paleontologist to know was less than optimal. Even a dying T. rex moves fast.

People gasped.

I took the microphone out of my pocket, and moved quickly to the front of the room. "Folks, we just got lucky. I'd like to inform those of you with tables by the window that the glass is rated at twenty tons per square inch. You're in no danger whatsoever. But you are in for quite a show. Those who are in the rear might want to get a little closer."

Young Philippe was off like a shot.

The creature was almost to us. "A tyrannosaur has a hyperacute sense of smell," I reminded them. "When it scents blood, its brain is overwhelmed. It goes into a feeding frenzy."

A few droplets of blood had spattered the window. Seeing us through the glass, Satan leaped and tried to smash through it.

Whoomp! The glass boomed and shivered with the impact. There were shrieks and screams from the diners, and several people started to their feet.

At my signal, the string quartet took up their instruments again, and began to play while Satan leaped and tore and snarled, a perfect avatar of rage and fury. They chose the scherzo from Shostokovich's piano quintet.

Scherzos are supposed to be funny, but most have a whirlwind, uninhibited quality that makes them particularly appropriate to nightmares and the madness of predatory dinosaurs.

Whoomp! That mighty head struck the window again and again and again. For a long time, Satan kept on frenziedly slashing at the window with his jaws, leaving long scratches in the glass.

Philippe pressed his body against the window with all his strength, trying to minimize the distance between himself and savage dino death. Shrieking with joyous laughter when that killer mouth tried to snatch him up. I felt for the kid, wanting to get as close to the action as he could. I could identify.

I was just like that myself when I was his age.

When Satan finally wore himself out and went bad-humoredly away, I returned to the de Chervilles. Philippe had restored himself to the company of his family. The kid looked pale and happy.

So did his sister. I noticed that she was breathing shallowly. Satan does that to young women.

"You dropped your napkin." I handed it to Melusine. Inside was a postcard-sized promotional map, showing Hilltop Station and behind it Tent City, where the researchers lived. One of the tents was circled. Under it was written, While the others are dancing.

I had signed it Don.

"When I grow up I'm going to be a paleontologist," the kid said fervently. "A behavioral paleontologist, not an anatomist or a wrangler." Somebody had come to take him home. His folks were staying to dance. And Melusine was long gone, off to Hawkins' tent.

"Good for you," I said. I laid a hand on his shoulder. "Come see me when you've got the education. I'll be happy to show you the ropes."

The kid left.

He'd had a conversion experience. I knew exactly how it felt. I'd had mine standing in front of the Zallinger "Age of Reptiles" mural in the Peabody Museum in New Haven. That was before time travel, when paintings of dinosaurs were about as real as you could get. Nowadays I could point out a hundred inaccuracies in how the dinosaurs were depicted. But on that distant sun-dusty morning in the Atlantis of my youth, I just stood staring at those magnificent brutes, head filled with wonder, until my mother dragged me away.

It really was a pity. Philippe was so full of curiosity and enthusiasm. He'd make a great paleontologist. I could see that. He wasn't going to get to realize his dreams, though. His folks had too much money to allow that.

I knew because I'd glanced through the personnel records for the next hundred years and his name wasn't there anywhere.

It was possibly the least of the thousands of secrets I held within me, never to be shared. Still, it made me sad. For an instant I felt the weight of all my years, every petty accommodation, every unworthy expedience. Then I went up the funnel and back down again to an hour previous.

Unseen, I slipped out and went to wait for Melusine.

Maintaining the funnel is expensive. During normal operations -- when we're not holding fund-raisers -- we spend months at a time in the field. Hence the compound, with its army surplus platform tents and electrified perimeter to keep the monsters out.
