My introduction: My name, Gregg Haljan. My age, twenty-five years. I was, at the time my narrative begins, Third Officer on the Space-Ship Planetara. Our line was newly established; in 2070, to be exact, following the modern improvements of the Martel Magnetic Levitation.[1 - As early as 1910 it was discovered that an object magnetized under certain conditions was subject to a loss of weight, its gravity partially nullified. The Martel discovery undoubtedly followed that method.]
Our ship, whose home port was Great-New York, carried mail and passenger traffic to and from both Venus and Mars. Of astronomical necessity, our flights were irregular. This spring, with the two other planets both close to the earth, we were making two complete round trips. We had just arrived in Great-New York, this May evening, from Grebhar, Venus Free State. With only five hours in port here, we were departing the same night at the zero hour for Ferrok-Shahn, capital of the Martian Union.
We were no sooner at the landing stage than I found a code-flash summoning Dan Dean and me to Divisional Detective Headquarters. Dan “Snap” Dean was one of my closest friends. He was radio-helio operator of the Planetara. A small, wiry, red-headed chap, with a quick, ready laugh and a wit that made everyone like him.
The summons to Detective-Colonel Halsey’s office surprised us. Snap eyed me.
“You haven’t been opening any treasury vaults, have you, Gregg?”
“He wants you, also,” I retorted.
He laughed. “Well, he can roar at me like a traffic switchman and my private life will remain my own.”
We could not think why we should be wanted. It was the darkness of mid-evening when we left the Planetara for Halsey’s office. It was not a long trip. We went direct in the upper monorail, descending into the subterranean city at Park-Circle 30.
We had never been to Halsey’s office before. We found it to be a gloomy, vaultlike place in one of the deepest corridors. The door lifted.
“Gregg Haljan and Daniel Dean.”
The guard stood aside. “Come in.”
I own that my heart was unduly thumping as we entered. The door dropped behind us. It was a small blue-lit apartment–a steel-lined room like a vault.
Colonel Halsey sat at his desk. And the big, heavy-set, florid Captain Carter–our commander of the Planetara–was here. That surprised us: we had not seen him leave the ship.
Halsey smiled at us gravely. Captain Carter said, “Sit down, lads.”
We took the seats. There was an alarming solemnity about this. If I had been guilty of anything that I could think of, it would have been frightening. But Halsey’s first words reassured me.
“It’s about the Grantline Moon Expedition. In spite of our secrecy, the news has gotten out. We want to know how. Can you tell us?”
Captain Carter’s huge bulk–he was about as tall as I am–towered over us as we sat before Halsey’s desk. “If you lads have told anyone–said anything–let slip the slightest hint about it–”
Snap smiled with relief; but he turned solemn at once. “I haven’t. Not a word!”
“Nor have I,” I declared.
The Grantline Moon Expedition! We had not thought of that as a reason for this summons. Johnny Grantline was a close friend to us both. He had organized an exploring expedition to the Moon. Uninhabited, with its bleak, forbidding, airless, waterless surface, the Moon–even though so close to the Earth–was seldom visited. No regular ship ever stopped there. A few exploring parties of recent years had come to grief.
But there was a persistent rumor that upon the Moon, mineral riches of fabulous wealth were awaiting discovery. The thing had already caused some interplanetary complications. The aggressive Martians would be only too glad to explore the Moon. But the U.S.W.[2 - “United States of the World,” which came into being in 2057 upon the centenary of the Yellow War.] definitely warned them away. The Moon was World Territory, we announced, and we would protect it as such.
The threatened conflict between the Earth and Mars had come to nothing. There was, this year of 2079, a thorough amity between all three of the inhabited planets. It still holds, and I pray that it may always hold.
There was, nevertheless, a realization by our government, that whatever riches might be upon the Moon should be seized at once and held by some reputable Earth Company. And when Johnny Grantline applied, with his father’s wealth and his own scientific record of attainment, the government was only too glad to grant him its writ.
The Grantline Expedition had started six months ago. The Martian government had acquiesced in our ultimatum, yet brigands have been known to be financed under cover of a governmental disavowal. And so the expedition was kept secret.
My words need give no offense to any Martian who comes upon them. I refer to the history of our earth only. The Grantline Expedition was on the Moon now. No word had come from it. One could not flash helios even in code without letting all the universe know that explorers were on the Moon. And why they were there, anyone could easily guess.
And now Colonel Halsey was telling us that the news was abroad! Captain Carter eyed us closely; his flashing eyes under the white bushy brows would pry a secret from anyone.
“You’re sure? A girl of Venus, perhaps, with her cursed, seductive lure! A chance word, with you lads befuddled by alcolite?”
We assured him we had been careful. By the heavens, I know that I had been. Not a whisper, even to Snap, of the name Grantline in six months or more.
Captain Carter added abruptly, “We’re insulated here, Halsey?”
“Yes, talk as freely as you like. An eavesdropping ray will never get into these walls.”
They questioned us. They were satisfied at last that, though the secret had escaped, we had not done it. Hearing it discussed, it occurred to me to wonder why Carter was concerned. I was not aware that he knew of Grantline’s venture. I learned now the reason why the Planetara, upon each of her voyages, had managed to pass fairly close to the Moon. It had been arranged with Grantline that if he wanted help or had any important message, he was to flash it locally to our passing ship. And this Snap knew, and had never mentioned it, even to me.
Halsey was saying, “Well, we can’t blame you, but the secret is out.”
Snap and I regarded each other. What could anyone do? What would anyone dare do?
Captain Carter said abruptly, “Look here, lads, this is my chance now to talk plainly to you. Outside, anywhere outside these walls, an eavesdropping ray may be upon us. You know that? One may never even dare whisper since that accursed ray was developed.”
Snap opened his mouth to speak but decided against it. My heart was pounding.
Captain Carter went on, “I know I can trust you two more than anyone else under me on the Planetara–”
“What do you mean by that?” I demanded. “What–”
He interrupted me. “Nothing at all but what I say.”
Halsey smiled grimly. “What he means, Haljan, is that things are not always what they seem these days. One cannot always tell a friend from an enemy. The Planetara is a public vessel. You have–how many is it, Carter?–thirty or forty passengers this trip to-night?”
“Thirty-eight,” said Carter.
“There are thirty-eight people listed for the flight to Ferrok-Shahn to-night,” Halsey said slowly. “And some may not be what they seem.” He raised his thin dark hand. “We have information–” He paused. “I confess, we know almost nothing–hardly more than enough to alarm us.”
Captain Carter interjected, “I want you and Dean to be on your guard. Once on the Planetara it is difficult for us to talk openly, but be watchful. I will arrange for us to be doubly armed.”
Vague, perturbing words! Halsey said, “They tell me George Prince is listed for the voyage. I am suggesting, Haljan, that you keep your eye especially upon him. Your duties on the Planetara leave you comparatively free, don’t they?”
“Yes,” I agreed. With the first and second officers on duty, and the captain aboard, my routine was more or less that of an understudy.
I said, “George Prince! Who is he?”
“A mechanical engineer,” said Halsey. “An under-official of the Earth Federated Radium Corporation. But he associates with bad companions–particularly Martians.”
I had never heard of this George Prince, though I was familiar with the Federated Radium Corporation, of course. A semi-government trust, which controlled virtually the entire Earth supply of radium.
“He was in the Automotive Department,” Carter put in. “You’ve heard of the Federated Radium Motor?”
We had, of course. A recent Earth invention which promised to revolutionize the automotive industry. An engine of a new type, using radium as its fuel.
Snap demanded, “What in the stars has this got to do with Johnny Grantline?”
