_The Coming of Ku Sui_
Straight through the vast cold reaches that stretched between one mighty
planet and another the _Scorpion_ arrowed, Carse and Friday standing
watch and watch, Sako always on duty with the latter. Behind, Saturn's
rings melted smaller, and ahead a dusky speck grew against the vault of
space until the red belts and one great seething crimson spot that
marked it as Jupiter stood out plainly. By degrees, then, the ship's
course was altered as Carse checked his calculations and made minor
corrections in speed and direction. So they neared the rendezvous. And a
puzzled furrow grew on Friday's brow.
What was bothering his master? Instead of becoming more impassive and
coldly emotionless as the distance shortened, he showed distinct signs
of worry. This might be natural in most men, but it was unusual in the
Hawk. Often the negro found him abstractedly smoothing his bangs of
hair, pacing the length of the control cabin, glancing, plainly worried,
at the visi-screen. What special thing was wrong? Friday wondered again
and again--and then, in a flash, he knew.
"Why--how we goin' to _see_ Dr. Ku?" he burst out. "Didn't that Judd say
somethin'----"
The Hawk nodded. "That's just the problem, Eclipse. For you'll remember
Judd said that Ku Sui 'comes out of darkness, out of empty space.' That
might mean invisibility or the Fourth Dimension--and God help us if he's
solved the problem of dimensional traveling. I don't know--but it's
something I can't well prepare against." He fell to musing again,
utterly lost in thought.
* * * * *
A day and a half later found Friday genuinely worried--an unusual state
for the always cheerful black. The laugh wrinkles of his face were
re-twisted into lines of anxiety which gave his face a most solemn and
lugubrious expression. From time to time he grasped the butt of his
ray-gun with a grip that would have pulped an orange; occasionally his
rolling brown eyes sought the gray ones of the Hawk, only to return as
by a magnet to the visi-screen, whose five adjoining squares mirrored
the whole sweep of space around them.
Jupiter now filled one side of the forward observation window. It was a
vast, red-belted disk, an eye-thrilling spectacle at their distance,
roughly a million miles. Against it were poised two small pale globes,
the larger of which was Satellite III. Several hours before, when they
had been closer to the satellite, Carse had scrutinized it through the
electelscope and made out above its surface a silver dot which was a
space-ship. It was bound inward toward Port o' Porno, and might well
have been one of Ku Sui's. But the _Scorpion_, slowing down for her
rendezvous, had attracted no attention and had passed undisturbed.
Now she hung motionless--that is, motionless with respect to the sun.
Only the whisper of the air-renewing machinery disturbed the tension in
her control cabin where the three men stood waiting, glancing back and
forth from the visi-screen to the Earth clock and its calendar
attachment. The date the clock showed was 24 January, the time, 10:21 P.
M. Dr. Ku Sui was one minute late.
Sako, the captive, was sullen and restless, and made furtive glances at
the Hawk, who stood detached, arms hanging carelessly at his sides, gray
eyes half closed, giving in his attitude no hint of the strain the
others were feeling. But his attitude of being relaxed and off his guard
was deceptive--as Sako found out. Suddenly his left hand seemed to
disappear; there was a hiss, an arrowing streak of spitting orange
light; and Sako was gaping foolishly at the arm he had stealthily raised
to one of the radio switches. A smoking sear had appeared as if by magic
across it.
Hawk Carse sheathed his gun. "I would advise you to try no more obvious
tricks," he said coldly. "Cutting in our microphone is too simple a way
to give warning to Dr. Ku Sui. Move away from there. And don't forget
your lines when Dr. Ku calls. You will never act a part before a more
critical and deadly audience."
Sako mumbled something and rubbed his arm. A pitying smile came to
Friday's face as he comprehended what had happened. "You damned fool!"
he said.
* * * * *
It was 10:22 P.M. Still, in the visi-screen, no other ship. Nothing but
the giant planet, the smaller satellites poised against it, and the deep
star-spangled curtain of black space all around.
They had carefully followed the instructions in the log. They were at
the exact place noted there: checked and double-checked. The radio
receiver was tuned to the wave-length given in the log. But of Ku Sui,
nothing.
And yet, in a way, he was with them. His enigmatic personality, his
seldom-seen figure was very present in their minds, and with it were
overtones of all the diabolic cunning and suave ironic cruelty that men
always associated with him. "He comes out of darkness, out of empty
space...." Friday licked his lips. He was not built for mental strain:
his lips kept drying and his tongue was as leather.
A little sputtering sound tingled the nerves of the three waiting men,
and as one their eyes went to the radio loudspeaker. A contact question
was being asked in the usual way:
"Are you there, Judd? Are you there, Judd? Are you there, Judd?"
The voice was not that of Ku Sui. It was a dead voice, toneless,
emotionless, mechanical.
"Are you there, Judd?" it went on, over and over.
"The mike switch, Friday," the Hawk said, and then was at Sako's side,
his ray-gun transfixing the man with its threatening angle. "Play your
part well," was the whisper from his lips.
The switch went over with a click. Trembling, Sako faced the microphone.
"This is Sako," he said.
"Sako?" the dead voice asked. "I want Judd. Where is Judd?"
"Judd is dead. The trap failed, and there was a fight on Iapetus. Judd
was killed by Carse, and most of the others. Only two of us are left,
but we have Carse and the negro, prisoners, alive. What are your
instructions?"
A half minute went by, and the three men hardly breathed.
"How do we know you are Sako?" said the voice at last. "Give the
recognition."
"The insignia of Dr. Ku Sui?"
"Yes. It is----"
Carse's ray-gun prodded the stomach of the sweating Sako.
"An asteroid," he said hastily, "in the center of a circle of the ten
planets."
The unseen speaker was quiet. Evidently he was conferring with someone
else, probably Ku Sui.
"All right," his toneless voice came back at last. "You will remain
motionless in your present position, keeping your radio receiver open
for further instructions. We are approaching and will be with you in
thirty minutes."
Carse motioned to Friday to switch off the mike. Sako sank limply into a
chair, soaked with perspiration.
"Now we must wait again," the Hawk murmured, crossing his arms and
scanning the visi-screen.
* * * * *
They had heard from Ku Sui, but that had not answered the old tormenting
question of how he would come. It was more puzzling than ever. The
visi-screen showed nothing, and it should have shown the Eurasian's
decelerating ship even at twice thirty minutes' time away. They looked
upon the same vista of Jupiter and his satellites, framed in eternal
blackness; there was no characteristic steely dot of an approaching ship
to give Carse the enemy's position and enable him to shape his plan of
reception definitely.
Twenty minutes went by. The strain the Hawk was under showed only in his
pulling at the bangs of flaxen hair that covered his forehead as far as
the eyebrows. He had, from Judd's words, expected a mystery in Ku Sui's
approach. There was nothing to do but wait; he had made what few plans
and preparations he could in advance.
Friday broke the tense silence in the control cabin. "He's _got_ to be
_somewhere_!" he exploded. "It isn't natural for the screen not to show
nothin'! Isn't there somethin' we can do?"
The Hawk was surprisingly patient. "I'm afraid not," he said. "It's
invisibility he's using, or else the fourth dimension, as Judd said. But
we've got one good chance. He'll send more instructions by radio, and
surely, after that, his ship will appear----"
A new voice, bland and unctuous, spoke in the control cabin from behind
the three men.
"_Not necessarily, my honored friend Carse_," it said. "_You will
observe there is no need for a ship to appear._"
Ku Sui had come.
