I banged the door upon him. The lacework of metal bridges and ladders seemed empty. I gazed up to the dome, and forward and aft. Twenty feet beneath me was the metal roof of the cabin superstructure. Below it, both sides of the deck showed. All patched with moonlight.
No one visible down there. I descended a ladder. The deck was empty. But in the silence something was moving! Footsteps moving away from me down the deck! I followed; and suddenly I was running. Chasing something I could hear, but could not see. It turned into the smoking room.
I burst in. And a real sound smothered the phantom. Johnson the purser was sitting here alone in the dimness. He was smoking. I noticed that his cigar held a long, frail ash. It could not have been him I was chasing. He was sitting there quite calmly. A thick-necked, heavy fellow, easily out of breath. But he was breathing calmly now.
He sat up with amazement at my wild-eyed appearance, and the ash jarred from his cigar.
“Gregg! What in the devil–”
I tried to grin. “I’m on my way to bed–worked all night helping Snap with those damn Earth messages.”
I went past him, out the door into the main interior corridor. It was the only way the invisible prowler could have gone. But I was too late now–I could hear nothing. I dashed forward into the main lounge. It was empty, dim and silent, a silence broken presently by a faint click–a stateroom door hastily closing. I swung and found myself in a tiny transverse passage. The twin doors of A 22 and A 20 were before me.
The invisible eavesdropper had gone into one of these rooms! I listened at each of the panels, but there was only silence within.
The interior of the ship was suddenly singing with the steward’s siren–the call to awaken the passengers. It startled me. I moved swiftly away. But as the siren shut off, in the silence I heard a soft, musical voice:
“Wake up, Anita–I think that’s the breakfast call.”
And her answer: “All right, George. I hear it.”
CHAPTER IV
I did not appear at that morning meal. I was exhausted and drugged with lack of sleep. I had a moment with Snap, to tell him what had occurred. Then I sought out Carter. He had his little chart-room insulated. And we were cautious. I told him what Snap and I had learned: the Gamma rays from the moon, proving that Grantline had concentrated a considerable ore-body. I also told him the message from Grantline.
“We’ll stop on the way back, as he directs, Gregg.” He bent closer to me. “At Ferrok-Shahn I’m going to bring back a cordon of Interplanetary Police. The secret will be out, of course, when once we stop at the moon. We have no right, even now, to be flying this vessel as unguarded as it is.”
He was very solemn. And he was grim when I told him of the invisible eavesdropper.
“You think he overheard Grantline’s message?”
“I don’t know,” I said.
“Who was it? You seem to feel it was George Prince?”
“Yes.”
I was convinced that the prowler had gone into A 20. When I mentioned the purser, who seemed to have been watching me earlier in the night, and again was sitting in the smoking room when the eavesdropper fled past, Carter looked startled.
“Johnson is all right, Gregg.”
“Is he? Does he know anything about this Grantline affair?”
“No–no,” said the captain hastily. “You haven’t mentioned it, have you?”
“Of course I haven’t. I’ve been wondering why Johnson didn’t hear that eavesdropper. I could hear him when I was chasing him. But Johnson sat perfectly unmoved and let him go by. What was he sitting there for, anyway, at that hour of the morning?”
“You’re too suspicious, Gregg. Overwrought. But you’re right–we can’t be too careful. I’m going to have that Prince suite searched when I catch it unoccupied. Passengers don’t ordinarily travel with invisible cloaks. Go to bed, Gregg–you need a rest.”
I went to my cabin. It was located aft, on the stern deck-space, near the stern watch-tower. A small metal room, with a desk, a chair and bunk. I made sure no one was in it. I sealed the lattice grill and the door, set the alarm trigger against any opening of them, and went to bed.
The siren for the mid-day meal awakened me. I had slept heavily. I felt refreshed. And hungry.
I found the passengers already assembled at my table when I arrived in the dining salon. It was a low-vaulted metal room of blue and yellow tube-lights. At the sides its oval windows showed the deck, with its ports of the dome-side, through which a vista of the starry firmament was visible. We were well on our course to Mars. The moon had dwindled to a pin-point of light beside the crescent earth. And behind them our sun blazed, visually the largest orb in the heavens. It was some sixty-eight million miles from the earth to Mars, this voyage. A flight, under ordinary circumstances, of some ten days.
There were five tables in the dining salon, each with eight seats. Snap and I had one of the tables. We sat at the ends, with three passengers on each of the sides.
Snap was in his seat when I arrived. He eyed me down the length of the table.
“Good morning, Gregg. We missed you at breakfast. Not pressure-sick, I hope?”
There were three passengers already seated at our table–all men. Snap, in a gay mood, introduced me.
“This is our third officer, Gregg Haljan. Big, handsome fellow, isn’t he? And as pleasant as he is good-looking. Gregg, this is Sero Ob Hahn.”
I met the keen, dark-eyed somber gaze of a Venus man of middle age. A small, slim, graceful man, with sleek black hair. His pointed face, accentuated by the pointed beard, was pallid. He wore a white and purple robe; upon his breast was a huge platinum ornament, a device like a star and cross entwined.
“I am happy to meet you, sir.” His voice was soft and sleek.
“Ob Hahn,” I repeated. “I should have heard of you, no doubt. But–”
A smile plucked at his thin, gray lips. “That is the error of mine, not yours. My mission is that all the universe shall hear of me.”
“He’s preaching the religion of the Venus Mystics,” Snap explained.
“And this enlightened gentleman,” said Ob Hahn ironically, “has just termed it fetishism. The ignorance–”
“Oh, I say!” protested the man at Ob Hahn’s side. “I mean, you seem to think I intended something opprobrious. As a matter of fact–”
“We’ve an argument, Gregg,” laughed Snap. “This is Sir Arthur Coniston, an English gentleman, lecturer and sky-trotter–that is, he will be a sky-trotter; he tells us he plans a number of voyages.”
The tall Englishman in his white linen suit bowed acknowledgment. “My compliments, Mr. Haljan. I hope you have no strong religious convictions, else we will make your table here very miserable!”
The third passenger had evidently kept out of the argument. Snap introduced him as Rance Rankin. An American–a quiet, blond fellow of thirty-five or forty.
I ordered my breakfast and let the argument go on.
“Won’t make me miserable,” said Snap. “I love an argument. You said, Sir Arthur?..
“I mean to say, I think I said too much. Mr. Rankin, you are more diplomatic.”
Rankin laughed. “I am a magician,” he said to me. “A theatrical entertainer. I deal in tricks–how to fool an audience–” His keen, amused gaze was on Ob Hahn. “This gentleman from Venus and I have too much in common to argue.”
“A nasty one!” the Englishman exclaimed. “By Jove! Really, Mr. Rankin, you’re a bit too cruel!”
I could see we were doomed
