inescapable heritage of his strange
childhood.
Orphaned almost at birth he had grown
to manhood on the lonely Moon, knowing
no living creature but the three unhuman
Futuremen. They had been his playmates,
his teachers, his inseparable companions.
Inevitably by that upbringing he was
forever set apart from his own kind.
Few people had ever penetrated that
barrier of reserve. Philip Carlin had been
one of them. And now Carlin was gone
into mystery.
“If I had been here,” Newton brooded,
“I'd never have let him go.”
A BRILLIANT scientist Carlin had set
out to study the mysteries of that strange
world inside Vulcan which the Futuremen
had discovered. He had hired a work-ship
with heavy anti-heat equipment to take him
to Vulcan, arranging for it to come back
there for him in six months.
But when the ship returned it had found
no trace of Carlin in the ruined city that
had been his base of operations. It had,
after a futile search, come back with the
news of his disappearance.
All this had happened before the return
of the Futuremen from their epoch-making
voyage to Andromeda. And now Curt
Newton was driving sunward, toward
Vulcan, to solve the mystery of Carlin's
fate.
Abruptly, from beyond the bulkhead
door of the bridge-room, two voices, one
deep and booming, the other lighter and
touched with an odd sibilance, were raised
in an outburst of argument.
Newton turned sharply. “Stop that
wrangling ! You'd better get those anti-
heaters going or we'll all fry.”
The door slid open and the remaining
members of the unique quartet came in.
One of them, at first glance, appeared
wholly human—with a lithe lean figure
and finely-cut features. And yet in his
pointed white face and bright ironic eyes
there lurked a disturbing strangeness.
A man but no kin to the sons of Adam.
An android, the perfect creation of
scientific craft and wisdom—humanity
carried to its highest power, and yet not
human. He carried his difference with an
air but Curt Newton was aware that Otho
was burdened with a loneliness far more
keen than any he could know himself.
The android said quietly, “Take it easy,
Curt. The unit’s already functioning.”
He glanced through the window at the
glaring vista of space and shivered. “I get
edgy myself, playing around the Sun this
close.”
Newton nodded. Otho was right. It was
one thing to come and go between the
planets, even between the stars. It was a
wholly different thing to dare approach the
Sun.
The orbit of Mercury was a boundary, a
limit. Any ship that went inside it was
challenging the awful power of the great
solar orb. Only ships equipped with the
anti-heat apparatus dared enter that zone of
terrible force—and then only at great peril.
Only the fourth of the Futuremen
seemed unworried. He crossed to the
window, his towering metal bulk looming
over them all. The same scientific genius
that had created the android had shaped
also this manlike metal giant, endowing
him with intelligence equal to the human
and with a strength far beyond anything
human.
Grag’s photoelectric eyes gazed steadily
from his strange metal face, into the wild
shaking glare. “I don't know what you’re
jumpy about,” he said. “The Sun doesn’t
bother me a bit.” He flexed his great
gleaming arms. “It feels good.”
“Stop showing off,” said Otho sourly.
“You'll burn out your circuits and we've
better things to do than trying to cram your
carcass out through the disposal lock.”
The android turned to Captain Future.
“You haven't raised Vulcan yet ?”
Newton shook his head. “Not yet.”
Presently a faint aura of hazy force
surrounded the little ship as it sped on—the
anti-heater unit building up full power.
