The dragon switched its tail, which was long and sinuous, and out on the floor Oop tumbled down ungracefully to duck the sweep of it.
Sylvester squawled in anger and crept forward a foot or so.
"Cut it out, Sylvester," Maxwell said sharply to the cat.
Oop scrambled forward hastily on his hands and knees and grabbed Sylvester by one of his hind legs.
"Talk to him," Maxwell said to Carol. "If that fool cat tackles him, there'll be the devil to pay."
"Oop, you mean. He wouldn't tackle Oop."
"Not Oop," said Maxwell. "The dragon. If he takes off on the dragon-"
A bellow of rage came thundering out of the darkness, and the thump of running feet.
"What is going on in here?" howled the watchman, charging from the shadows.
The dragon spun upon the pedestal and came swiftly off it, switching around to face the running watchman.
"Look out," Oop yelled, still with a tight grip upon Sylvester's leg.
The dragon moved forward carefully, almost mincingly, its head canted at a questioning angle. It flourished its tail and the tail swept across the top of a display table, brushing off a half dozen bowls and jugs. The pottery thudded and gleaming shards went skating across the floor.
"Hey, you cut that out!" the watchman yelped and then, apparently for the first time, saw the dragon. The yelp turned into a howl of fear. The watchman turned and fled. The dragon trotted after him, not in any hurry, but very interested. His progress was marked by a series of thudding and splintering crashes.
"If we don't get him out of here," said Maxwell, "there'll be nothing left. At the rate he's going, there won't be a thing intact in less than fifteen minutes. He'll have the place wiped out. And, Oop, for the love of God, hang onto that cat. We don't want a full-fledged brawl breaking out in here."
Maxwell got to his feet, grabbed the interpreter off his head and stuffed it in his pocket.
"I could open the doors," Carol offered, "and we could shoo him out of here. The big doors, I mean. I think that I know how."
"How are you, Oop," Maxwell asked, "at dragon-herding?"
The dragon had blundered to the rear of the building and now had turned around and was coming back.
"Oop," said Carol, "help me with these doors. I need a man with muscle."
"What about this cat?"
"Leave him to me," said Maxwell. "He may behave himself. Maybe he'll mind me."
A long chain of crashes marked the progress of the dragon. Listening to them, Maxwell moaned. Sharp would have his scalp for this. Friend or not, he would be plenty sore. The whole museum wrecked and the Artifact transformed into rampaging tons of flesh.
He took a few tentative steps across the floor toward the crashing sounds. Sylvester slunk close against his heels. In the dimness, Maxwell could make out the dim outlines of the floundering dragon.
"Nice dragon," Maxwell said. "Take it easy, fellow."
It sounded rather silly and somehow inadequate. How in the world, he wondered, should one talk to a dragon?
Sylvester let out a hacking growl.
"You stay out of it," said Maxwell sharply. "Things are bad enough without you messing in."
He wondered what had happened to the watchman.
More than likely phoning the police and building up a storm.
Behind him he heard the creaking of the doors as they came open. If the dragon would only wait until those doors were open, then he could be shagged outdoors. And once the dragon had been gotten out, what would happen then? Maxwell shuddered, thinking of it-of the great beast blundering down the streets and across the malls. Maybe it would be better, after all, to keep him penned in here.
He stood indecisively for a moment, weighing the disadvantages of a dragon caged with a dragon on the loose. The museum was more or less wrecked now and perhaps the complete wrecking of it would be preferable to turning this creature loose upon the campus.
The doors still were creaking, slowly opening. The dragon had been ambling along, but now he burst into a gallop, heading for the opening portal.
Maxwell spun around. "Close those doors!" he shouted then ducked quickly to one side as the galloping dragon came charging down upon him.
The doors were partly open and they stayed partly open. Oop and Carol were racing off in different directions, intent on leaving plenty of room for the lumbering tons of flesh that were heading for the open.
Sylvester's thunderous roars boomed and echoed in the museum as he took off in pursuit of the running creature.
Off to one side, Carol was shrieking at him. "Cut it out, Sylvester! No, Sylvester, no!"
The dragon's sinuous tail flicked nervously from side to side as it ran. Cabinets and tables crashed, statues were sent spinning-a path of destruction marked the dragon's flight for freedom.
Groaning, Maxwell ran, following Sylvester and the dragon, although, for the life of him, he didn't know exactly why he should be running. He didn't, he was certain, want to catch the dragon.
The dragon reached the opening and went through it in a single leap, high into the air, and as it leaped, the wings unfolded and swept downward in a thrumming beat.
At the doorway Maxwell skidded to a stop. On the steps below the entrance, Sylvester also had spun to a sliding halt and now was straining upward, raging loudly at the flying dragon.
It was a sight to make one catch his breath. Moonlight on the beating wings, reflecting off the burnished scales of red and gold and blue, made a flashing rainbow that quivered in the sky.
Oop and Carol burst out of the door and stopped to stare into the sky.
"Beautiful!" said Carol.
"Yes, isn't it," said Maxwell.
And now, for the first time, he realized in full exactly what had happened here. There was no longer any Artifact and the Wheeler deal was dead. And, likewise, any deal that he could make in behalf of the crystal planet. The chain of events that had been started with the copying of his wave pattern when he had been launched for Coonskin had been canceled out. Now, except for that flashing rainbow in the sky, it was as if nothing at all had happened.
The dragon was higher now, wheeling in the sky, no longer anything more than the flashing of the rainbow colors.
"This tears it," Oop declared. "What do we do now?"
"It was my fault," said Carol.
"It was no one's fault," said Oop. "It's just the way things happen."
"Well, anyhow," said Maxwell, "we loused up Harlow deal."
"I'll say you did," a voice said behind them. "Will someone please tell me what is going on?"
They turned around.
Harlow Sharp stood in the doorway. Someone had turned on all the museum lights and he stood out sharply against the lighted oblong of the doors.
"The museum is wrecked," he said, "and the Artifact gone and here are the two of you and I might have known Miss Hampton, I'm astonished. I thought you had better sense than to become entangled in such low company, though that crazy cat of yours-"
"You leave Sylvester out of this," she said. "He never had a thing to do with it."
"Well, Pete?" asked Sharp.
Maxwell shook his head. "I find it a bit hard to explain."
"I would think so," said Sharp. "Did you have all this in mind when you talked with me this evening?"
"No," said Maxwell. "It was a sort of accident."
"An expensive accident," said Sharp. "It might interest you to know that you've set Time's work back a century or more. Unless, of course, you somehow moved the Artifact and have it hidden out somewhere. In which case, my friend, I give you a fiat five seconds to hand it back to me."
