"He has a radio?" Arnold asked.
"Of course," Myra said. "He keeps it so he can listen to the absurd voices of mankind, and laugh himself to sleep."
"Oh. Go on."
"Well, when he heard I was going to live on Coelle, he became furious. Said he couldn't stand having a human so close."
"That's ridiculous," Arnold said. "The planets are millions of miles apart."
"I told him that. But he started shouting and screaming at me. He said mankind wouldn't leave him alone. Real-estate brokers were trying to talk him into selling his mineral rights, and a travel agency was going to route its ships within ten thousand miles of the upper atmosphere of his planet. And then, to top it all, I come along and move in practically on his doorstep."
"And then he threatened her," Jameson said.
"I guess it was a threat," Myra said. "He told me to get out of the Gelsors system, or he wouldn't be responsible for what happened."
"Did he say what would happen?" Arnold asked.
"No. He just hinted it would be pretty extreme."
Jameson said, "I think it's apparent that the man's unbalanced.
After the talk, these so-called Skag incidents began. There must be a connection."
"It's possible," Arnold said judiciously.
"I just can't believe it," Myra said, gazing pensively out a port. "His book was so beautiful. And his picture on the book jacket — he looked so soulful."
"Hah!" Jameson said. "Anyone who'd live alone on an empty planet must be off his rocker."
Myra gave him a venomous look. And then the radar alarm went off. They were about to land on Coelle...
The Skag Castle dominated Coelle. Built of an almost indestructible gray stone, the castle sprawled across the curved land like a prehistoric monster crouched over Lilliput. Its towers and battlements soared past the narrow limits of the planet's atmosphere, and the uppermost spires were lost in haze. As they approached, the black slit windows seemed to stare menacingly at them.
"Cozy little place," Gregor commented.
"Isn't it wonderful?" Myra said. "Come on. I'll show you around."
The three men looked at the castle, then at each other.
"Just the ground floor," Arnold begged.
Myra wanted to show them everything. It wasn't every girl who became the owner of an alien birthplace, period house, and haunted castle, all rolled into one. But she settled for a few of the main attractions: the library — containing ten thousand Skag scrolls that no one could read — the Worship Chamber of Ieele, and the Grand Torture Room.
Dinner was prepared by the auto-cook Uncle Jim had thoughtfully installed, and later they had brandy on the terrace, under the stars. Myra gave them all bedrooms on the second floor, to avoid as much climbing as possible. They retired, planning to begin the investigation early in the morning.
The partners shared a bedroom the size of a small soccer field, with bronze death masks of Scarb princes leering from the wall. Arnold kicked off his shoes, flopped into bed, and was asleep immediately.
Gregor paced around for a few minutes, smoked a last cigarette, snapped off the light, and climbed into his bed. He was on the verge of sleep, when suddenly he sat upright. He thought he had heard a dull rumbling noise, like the sound of a giant walking underneath the castle. Nerves, he told himself.
Then the rumbling came again, the floor shook, and the death masks clattered angrily against the wall.
In another moment the noise had subsided.
"Did you hear it?" Gregor whispered.
"Of course I heard it," Arnold said crossly. "It almost shook me out of bed."
"What do you think?"
"It could be a form of poltergeist," Arnold answered, "although I doubt it. We'll explore the cellar tomorrow."
"I don't think this place has any cellar," Gregor said.
"It hasn't? Good! That would clinch it."
"What? What are you talking about?"
"I'll have to accumulate a bit more data before I can make a positive statement," Arnold said smugly.
"Have you any idea what you're talking about? Or are you just making it up as you go along? Because if—"
"Look!"
Gregor turned and saw a gray and purple light in one corner of the room. It pulsed weirdly, throwing fantastic shadows across the bronze death masks. Slowly it approached them. As it drew nearer they could make out the reptilian outlines of a Skag, and through him they could see the walls of the room.
Gregor fumbled under his pillow, found the needler, and fired. The charge went through the Skag, and pocked a neat three-inch groove in the stone wall.
The Skag stood before them, its cloak swirling, an expression of extreme disapproval on its face. And then, without a sound, it was gone.
As soon as he could move, Gregor snapped on the light. Arnold was smiling faintly, staring at the place where the Skag had been.
"Very interesting," Arnold said. "Very interesting indeed." "What is?"
"Do you remember how Myra described the Undead Scarb?"
"Sure. She said it was nine feet tall, had little wings, and — oh, I think I see."
"Precisely," Arnold said. "This Skag or Scarb was no more than four feet in height, without wings."
"I suppose there could be two types," Gregor said dubiously. "But what bearing does this have on the underground noises? The whole thing is getting ridiculously complicated. Surely you must realize that."
"Complication is frequently a key to solution," Arnold said. "Simplicity alone is baffling. Complexity, on the other hand, implies the presence of a self-contradictory logic structure. Once the incomprehensibles are reconciled and the extraneous factors canceled, the murderer stands revealed in the glaring light of rational inevitability."
"What are you talking about?" Gregor shouted. "There wasn't any murder here!"
"I was quoting from Lesson Three in the Hepburn School for Scientific Detection Correspondence Course. And I know there was no murder. I was just speaking in general."
"But what do you think is going on?" Gregor asked.
"Something funny is going on," Arnold said. He smiled knowingly, turned over, and went to sleep.
Gregor snapped out the light. Arnold's course, he remembered, had cost ten dollars plus a coupon from Horror Crime Magazine. His partner had certainly received his money's worth.
There were no further incidents that night.
IV
Bright and early in the morning, the partners were awakened by Myra pounding on their door.
"A spaceship is landing!" she called.
Hurriedly they dressed and came down, meeting Jameson on the stairs. Outside they saw that a small spacer had just put down, and its occupant was climbing out.
"More trouble," Jameson growled.
The new arrival hardly looked like trouble. He was middle- aged, short, and partially bald. He was dressed in a severely conservative business suit, and he carried a briefcase. His features were quiet and reserved.
"Permit me to introduce myself," he said. "I am Frank Olson, a representative of Transstellar Mining. My company is contemplating an expansion into this territory, to take advantage of the new Terra-to-Propexis space lane. I am doing the initial survey. We need planets upon which we can obtain mineral rights."
Myra shook her head. "Not interested. But why don't you try Kerma?" she asked with a sly smile.
"I just came from Kerma," Olson said. "I had what I considered a very attractive proposition for this Edward the Hermit fellow."
"I'll bet he booted you out on your ear," Gregor said.
"No. As a matter of fact, he wasn't there."
"Wasn't there?" Myra gasped. "Are you sure?"
