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."

Maxwell gulped. "I didn't move it, Harlow. In fact, I barely touched it. I'm not sure what happened. It turned into a dragon."

"It turned into a what?"

"A dragon. I tell you, Harlow "

"I remember now," said Sharp. "You always were blathering around about a dragon. You started out for Coonskin to find yourself a dragon. And now it seems you've found one. I hope that it's a good one."

"It's a pretty one," said Carol. "All gold and shimmery."

"Oh, fine," said Sharp. "Isn't that just bully. We can probably make a fortune, taking it around on exhibition. We can whomp up a circus and give top billing to the dragon. I can see it now in great big letters: THE ONLY DRAGON IN EXISTENCE."

"But it isn't here," said Carol. "It up and flew away."

"Oop," said Sharp, "you haven't said a word. What is going on? You are ordinarily fairly mouthy. What is going on?"

"I'm mortified," said Oop.

Sharp turned away from him and looked at Maxwell.

"Pete," he said, "you probably realize what you have done. The watchman phoned me and wanted to call the police. But I told him to hold up on calling the police and I'd come right down. I had no idea it would turn out as bad as it did turn out to be. The Artifact is gone and I can't deliver it and that means I'll have to hand back all that cash, and a lot of the exhibits have been smashed to smithereens-"

"The dragon did that," Maxwell said, "before we let him out."

"So you let him out? He didn't actually get away. You just let him out."

"Well, he was smashing all that stuff. I guess we weren't thinking."

"Tell me honest, Pete. Was there actually a dragon?"

"Yes, there was one. He was immobilized inside the Artifact. Perhaps he was the Artifact. Don't ask me how he got there. Enchantment, I would guess."

"Enchantment?"

"Enchantment really happens, Harlow. I don't know how. I've spent years trying to find out and I don't know much more about it now than when I started out."

"It seems to me," said Sharp, "that there is someone missing. When all hell breaks loose, there usually is someone else who is tied into it. Can you tell me, Oop, where Ghost, that great, good friend of yours, might be?"

Oop shook his head. "He's a hard one to keep track of. Always slipping off."

"That isn't all of it," said Sharp. "There is still another situation that we should pay some heed to. Shakespeare has come up missing. I wonder if any of you could shed some light on his disappearance."

"He was with us for a while," said Oop. "We were just settling down to eat when he became quite frightened and lit out of there. It happened when Ghost remembered that he was Shakespeare's ghost. He's been wondering all these years, you know, who he is the ghost of."

Slowly, lowering himself one section at a time, Sharp sat down on the top step and looked slowly from one to the other of them.

"Not a thing," he said. "You didn't miss a thing when you started out to ruin Harlow Sharp. You made a job of it."

"We didn't start out to ruin you," said Oop. "We never had a thing against you. It seemed, somehow, that things started going wrong and they never stopped."

"By rights," said Sharp, "I should sue every one of you for every cent you have. I should ask a judgment-and don't fool yourself, I'd get it-that would keep all of you working for Time the rest of your natural lives. But the three of you together couldn't offset by a fraction, during your collective lifetimes, what you cost Time tonight. So there's no sense in doing it. Although I suppose the police will have to get into this ruckus. I don't see how they can be kept out of it. The three of you, I'm afraid, will have to answer a lot of questions."

"If someone would only listen to me," said Maxwell, "I could explain it all. That's what I've been trying to do ever since I got back-to find someone who would listen to me. I tried to talk to you this afternoon..."

"Then," said Sharp, "suppose you start right now by explaining it to me. I'll own to a slight curiosity. Let's go across the street to my office, where we can settle down and have a talk. Or might that inconvenience you? There's probably a thing or two you still have to do to finish up the job of bankrupting Time."
