What an idiot I had been! We denizens of Earth have a common vice: we take what we're offered, whether we need it or not.

You can get into a lot of trouble that way.

But the derg was gone and the worst of my troubles were over. I'd sit tight for a while, give things a chance to work themselves out. In a few weeks, perhaps, I'd….

There seemed to be a humming in the air.

I sat upright on the bed. One corner of the room was curiously dark and I could feel a cold breeze on my face. The hum grew louder — not really a hum, but laughter, low and monotonous.

At that point, no one had to draw me a diagram.

"Derg!" I screamed. "Get me out of this!"

He was there. "Mistletoe! Just wave it at the gamper."

"Where in blazes would I get mistletoe?"

"Iron and copper then!"

I leaped to my desk, grabbed a copper paperweight and looked wildly for some iron to bond it to. The paperweight was pulled out of my hand. I caught it before it fell. Then I saw my fountain pen and brought the point against the paperweight.

The darkness vanished. The cold disappeared.

I guess I passed out.

The derg said triumphantly, an hour later, "You see? You need my protection."

"I suppose I do," I answered dully.

"You will need some things," the derg said. "Wolfsbane, amarinth, garlic, graveyard mold —"

"But the gamper is gone."

"Yes. However, the grailers remain. And you need safeguards against the leeps, the feegs, and the melgerizer."

So I wrote down his list of herbs, essences, and specifics. I didn't bother asking him about this link between supernatural and supernormal. My comprehension was now full and complete.

Ghosts and spirits? Or extraterrestrials? All the same, he said, and I saw what he meant. They leave us alone, for the most part. We are on different levels of perception, of existence, even. Until a human is foolish enough to attract attention to himself.

Now I was in their game. Some wanted to kill me, some to protect me, but none care for me, not even the derg. They were interested solely in my value to the game, if that's what it was.

And the situation was my own fault. At the beginning, I had had the accumulated wisdom of the human race at my disposal, that tremendous racial hatred of witches and ghosts, the irrational fear of alien life. For my adventure has been played out a thousand times and the story is told again and again — how a man dabbles in strange arts and calls to himself a spirit. By so doing, he attracts attention to himself — the worst thing of all.

So I was welded inseparably to the derg and the derg to me. Until yesterday, that is. Now I am on my own again.

Things had been quiet for a few weeks. I had held off the feegs by the simple expedient of keeping my closet doors closed. The leeps were more menacing, but the eye of a toad seemed to stop them. And the melgerizer was dangerous only in the full of the Moon.

"You are in danger," the derg said yesterday.

"Again?" I asked, yawning.

"It is the thrang who pursues us."

"Us?"

"Yes, myself as well as you, for even a derg must run risk and danger."

"Is this thrang particularly dangerous?"

"Very."

"Well, what do I do? Snakeskin over the door? A pentagon?"

"None of those," the derg said. "The thrang must be dealt with negatively, by the avoidance of certain actions."

By now, there were so many restrictions on me, I didn't think another would matter. "What shouldn't I do?"

"You must not lesnerize," the derg said.

"Lesnerize?" I frowned. "What's that?"

"Surely you know. It is a simple, everyday human action."

"I probably know it under a different name. Explain."

"Very well. To lesnerize is to —" He stopped abruptly.

"What?"

"It is here! The thrang!"

I backed up against a wall. I thought I could detect a faint stirring of dust, but that might have been no more than overwrought nerves.

"Derg!" I shouted. "Where are you? What should I do?"

I heard a shriek and the unmistakable sound of jaws snapping.

The derg cried, "It has me!"

"What should I do?" I cried again.

There was a horrible noise of teeth grinding. Very faintly, I heard the derg say, "Don't lesnerize!"

And then there was silence.

So I'm sitting tight now. There'll be an airplane crash in Burma next week, but it shouldn't affect me here in New York. And the feegs certainly can't harm me. Not with all my closet doors closed.

No, the problem is lesnerizing. I must not lesnerize. Absolutely not. If I can keep from lesnerizing, everything will pass and the chase will move elsewhere. It must! All I have to do is wait them out.

The trouble is, I don't have any idea what lesnerizing might be. A common human action, the derg had said. Well, for the time, I'm avoiding as many actions as possible.

I've caught up on some back sleep and nothing happened, so that's not lesnerizing. I went out and bought food, paid for it, cooked it, ate it. That wasn't lesnerizing. I wrote this report. That wasn't lesnerizing.

I'll come out of this yet.

I'm going to catch a nap. I think I have a cold coming on. Now I have to sneez
