Chapter 18

_In the Zed-light Glow_

"Try again. By the infernal, Snap Dean, if you do anything to balk us!"

Miko scanned the apparatus with keen eyes. How much technical knowledge of signaling instruments did this brigand leader have? I was tense and cold with apprehension as I sat in a corner of the helio-room, watching Snap. Could Miko be fooled? Snap, I knew, was trying to fool him.

The Moon spread close beneath us. My log-chart, computed up to thirty minutes past, showed us barely some thirty thousand miles over the Moon's surface. The globe lay in quadrature beneath our bow quarter--a huge quadrant spreading across the black starry vault of the lower heavens. A silver quadrant. The sunset caught the Lunar mountains, flung slanting shadows over the empty Lunar plains. All the disc was plainly visible. The mellow Earth-light glowed serene and pale to illumine the Lunar night.

The _Planetara_ was bathed in silver. A brilliant silver glare swept the forward deck, clean white and splashed with black shadows. We had partly circled the Moon, so as now to approach it from the Earthward side. I had worked with extreme concentration through the last few hours, plotting the trajectory of our curving sweep, setting the gravity plates with constantly shifting combinations. And with it a necessity for the steady retarding of our velocity.

* * * * *

Miko for a time was at my elbow in the turret. I had not seen Coniston and Hahn of recent hours. I had slept, awakened refreshed, and had a meal. Coniston and Hahn remained below, one or the other of them always with the crew to execute my sirened orders. Then Coniston came to take my place in the turret, and I went with Miko to the helio-room.

"You are skilful, Haljan." A measure of grim approval was in Miko's voice. "You evidently have no wish to try and fool me in this navigation."

I had not, indeed. It is delicate work at best, coping with the intricacies of celestial mechanics upon a semicircular trajectory with retarding velocity, and with a make-shift crew we could easily have come upon real difficulty.

We hung at last, hull-down, facing the Earthward hemisphere of the Lunar disc. The giant ball of the Earth lay behind and above us--the Sun over our stern quarter. With forward velocity almost checked, we poised, and Snap began his signals to the unsuspecting Grantline.

My work momentarily was over. I sat watching the helio-room. Moa was here, close beside me; I felt always her watchful gaze, so that even the play of my expression needed reining.

Miko worked with Snap. Anita too was here. To Miko and Moa it was the somber, taciturn George Prince, shrouded always in his black mourning cloak, disinclined to talk; sitting alone, brooding and cowardly sullen.

Miko repeated, "By the infernal, if you try to fool me, Snap Dean!"

The small metal room, with its grid floor and low-arched ceiling, glared with moonlight through its windows. The moving figures of Snap and Miko were aped by the grotesque, misshapen shadows of them on the walls. Miko gigantic--a great, menacing ogre. Snap small and alert--a trim, pale figure in his tight-fitting white trousers, broad-flowing belt, and white shirt open at the throat. His face was pale and drawn from lack of sleep and the torture to which Miko had subjected him. But he grinned at the brigand's words, and pushed his straggling hair closer under the red eyeshade.

"I'm doing my best, Miko--you can believe it."

* * * * *

The room over long periods was deadly silent, with Miko and Snap bending watchfully at the crowded banks of instruments. A silence in which my own pounding heart seemed to echo. I did not dare look at Anita, nor she at me. Snap was trying to signal Earth, not the Moon! His main helios were set in the reverse. The infra-red waves, flung from the bow window, were of a frequency which Snap and I believed that Grantline could not pick up. And over against the wall, close beside me and seemingly ignored by Snap, there was a tiny ultra-violet sender. Its faint hum and the quivering of its mirrors had so far passed unnoticed.

Would some Earth-station pick it up? I prayed so. There was a thumb nail mirror here which could bring an answer. I prayed that it might swing.

Would some Earth telescope be able to see us? I doubted it. The pinpoint of the _Planetara's_ infinitesimal bulk would be beyond them.

Long silences, broken only by the faint hiss and murmur of Snap's instruments.

"Shall I try the 'graphs, Miko?"

"Yes."

I helped him with the spectroheliograph. At every level the plates showed us nothing save the scarred and pitted Moon-surface. We worked for an hour. There was nothing. Bleak cold night on the Moon here beneath us. A touch of fading sunlight upon the Apennines. Up near the South Pole, Tycho with its radiating open rills stood like a grim dark maw.

Miko bent over a plate. "Something here? Is there?"

An abnormality upon the frowning ragged cliffs of Tycho? We thought so. But then it seemed not.

* * * * *

Another hour. No signal came from Earth. If Snap's calls were getting through we had no evidence of it. Abruptly Miko strode at me from across the room. I went cold and tense; Moa shifted, alert to my every movement. But Miko was not interested in me. A sweep of his clenched fist knocked the ultra-violet sender and its coils and mirrors in a tinkling crash to the grid at my feet.

"We don't need that, whatever it is!"

He rubbed his knuckles where the violet waves had tinged them, and turned grimly back to Snap.

"Where are your Gamma ray mirrors? If the treasure is exposed--"

This Martian's knowledge was far greater than we believed. He grinned sardonically at Anita. "If our treasure is on this hemisphere, Prince, we should pick up Gamma rays? Don't you think so? Or is Grantline so cautious it will all be protected?"

Anita spoke in a careful, throaty drawl. "The Gamma rays came plain enough when we passed here on the way out."

"You should know," grinned Miko. "An expert eavesdropper, Prince--I will say that for you. Come Dean, try something else. By God, if Grantline does not signal us, I will be likely to blame you--my patience is shortening. Shall we go closer, Haljan?"

"I don't think it would help," I said.

He nodded. "Perhaps not. Are we checked?"

"Yes." We were poised, very nearly motionless. "If you wish an advance, I can ring it. But we need a surface destination now."

"True, Haljan." He stood thinking. "Would a zed-ray penetrate those crater-cliffs? Tycho, for instance, at this angle?"[B]

"It might," Snap agreed. "You think he may be on the Northern inner side of Tycho?"

"He may be anywhere," said Miko shortly.

"If you think that," Snap persisted, "suppose we swing the _Planetara_ over the South Pole. Tycho, viewed from there--"

"And take another quarter-day of time?" Miko sneered. "Flash on your zed-ray; help him hook it up, Haljan."

[B] An allusion to the use of the zed-ray light for making spectro-photographs of what might be behind obscuring rock masses, similar to the old-style X-ray.

* * * * *

I moved to the lens-box of the spectroheliograph. It seemed that Snap was very strangely reluctant: Was it because he knew that the Grantline camp lay concealed on the north inner wall of Tycho's giant ring? I thought so. But Snap flashed a queer look at Anita. She did not see it, but I did. And I could not understand it.

My accursed, witless incapacity! If only I had taken warning!

"Here," commanded Miko. "A score of 'graphs with the zed-ray. I tell you I will comb this surface if we have to stay here until our ship comes from Ferrok-Shahn to join us!"

The Martian brigands were coming. Miko's signals had been answered. In ten days the other brigand ship, adequately manned and armed, would be here.

Snap helped me connect the zed-ray. He did not dare even to whisper to me, with Moa hovering always so close. And for all Miko's sardonic smiling, we knew that he would tolerate nothing from us now. He was fully armed, and so was Moa.

I recall that Snap several times tried to touch me significantly. Oh, if only I had taken warning!

We finished our connecting. The dull gray point of zed-ray gleamed through the prisms, to mingle with the moonlight entering the main lens. I stood with the shutter trip.

"The same interval, Snap?"

"Yes."

Beside me, I was aware of a faint reflection of the zed-light--a gray Cathedral shaft crossing the helio-room and falling upon the opposite wall. An unreality there, as the zed-light faintly strove to penetrate the metal room-side.

I said, "Shall I make the exposure?"

* * * * *

Snap nodded. But that 'graph was never made. An exclamation from Moa made us all turn. The Gamma mirrors were quivering! Grantline had picked our signals! With what undoubtedly was an intensified receiving equipment which Snap had not thought Grantline able to use, he had caught our faint zed-rays, which Snap was sending only to deceive Miko. And Grantline had recognized the _Planetara_, and had released his occulting screens surrounding the radium ore. The Gamma rays were here, unmistakable!

And upon their heels came Grantline's message. Not in the secret system he had arranged with Snap, but unsuspectingly in open code. I could read the swinging mirror, and so could Miko.

And Miko decoded it triumphantly aloud:

"_Surprised but pleased your return. Approach Mid-Northern hemisphere, region of Archimedes, forty thousand toises[C] off nearest Apennine range._"

The message broke off. But even its importance was overshadowed. Miko stood in the center of the helio-room, triumphantly reading the light-indicator. Its beam swung on the scale, which chanced to be almost directly over Anita's head. I saw Miko's expression change. A look of surprise, amazement came to him.

"Why--"

He gasped. He stood staring. Almost stupidly staring for an instant. And as I regarded him with fascinated horror, there came upon his heavy gray face a look of dawning comprehension. And I heard Snap's startled intake of breath. He moved to the spectroheliograph, where the zed-ray connections were still humming.

But with a leap Miko flung him away. "Off with you! Moa, watch him! Haljan, don't move!"

[C] About fifty miles.

* * * * *

Again Miko stood staring. Oh dear God, I saw now that he was staring at Anita!

"Why George Prince! How strange you look!"

Anita did not move. She was stricken with horror: she shrank back against the wall, huddled in her cloak. Miko's sardonic voice came again:

"How strange you look. Prince!" He took a step forward. He was grim and calm. Horribly calm. Deliberate. Gloating--like a great gray monster in human form toying with a fascinated, imprisoned bird.

"Move just a little Prince. Let the zed-ray light fall more fully."

Anita's head was bare. That pale, Hamletlike face. Dear God, the zed-light reflection lay gray and penetrating upon it!

Miko took another step. Peering. Grinning. "How amazing, George Prince! Why, I can hardly believe it!"

Moa was armed with an electronic cylinder. For all her amazement--what turgid emotions sweeping her I can only guess--she never took her eyes from Snap and me.

"Back! Don't move, either of you!" She hissed it at us.

Then Miko leaped at Anita like giant gray leopard pouncing.

"Away with that cloak, Prince!"

* * * * *

I stood cold and numbed. And realization came at last. The faint zed-light glow had fallen by chance upon Anita's face. Penetrated the flesh; exposed, faintly glowing, the bone-line of her jaw. Unmasked the waxen art of Glutz.

And Miko had seen it.

"Why George, how surprising! Away with that cloak!"

He seized her wrist, drew her forward, beyond the shaft of zed-light, into the brilliant light of the Moon. And ripped her cloak from her. The gentle curves of her woman's figure were so unmistakable!

And as Miko gazed at them, all his calm triumph swept away.

"Why, Anita!"

I heard Moa mutter: "So that is it?" A venomous flashing look--a shaft from me to Anita and back again. "So that is it?"

"Why, _Anita_!"

Miko's great arms gathered her up as though she were a child. "So I have you back; from the dead delivered back to me!"

"Gregg!" Snap's warning, and his grip over my shoulders brought me a measure of sanity. I had tensed to spring. I stood quivering, and Moa thrust her weapon against my face. The helio mirrors were swaying again with another message from Grantline. But it came ignored by us all.

In the glare of moonlight by the forward window, Miko held Anita, his great hands pawing her with triumphant possessive caresses.

"So, little Anita, you are given back to me."

Against her futile struggles he held her.

Dear God, if only I had had the wit to have prevented this!
