An incisive voice from the doorway way interrupted, "Never mind what he
thinks, Carson. I'll do the thinking from now on."

At one man they turned to face the speaker. It was the guard, Antazzo,
and he was clothed from neck to ankles in a garment of bright metallic
stuff that shimmered with shifting colors like those of a soap bubble.
A mask of similar stuff covered his face, and in each hand there was a
weapon resembling a ray pistol but of strangely unfamiliar design.

Mahoney shot from the hip and his stabbing ray splashed full on the
hunchback's chest--but harmlessly. That lustrous garment was an
insulating armor; the traitorous guard should have been shriveled to a
cinder at the contact. Antazzo laughed evilly as his own weapons loosed
strange and terrible energies.

Tom Farley ducked, and Blaine watched in horrified amazement as the
crackling streamers of blue radiance from the dwarf's pistols found
their marks. Mahoney and Kelly, standing there, bathed for a brief
instant in horrid blue fire: tottering, swaying, their mouths opened
wide in a last agonized effort, to cry out. Tiny pinpoints of brilliant
pyrotechnics flashing and exploding within the columns of blue fire.
Then, nothing! Where the two husky guards had stood there was utter
emptiness; not even a shred of clothing remained. The air in the
control room became heavy and acrid.

"Antazzo!" White-faced and shaking, Blaine cried out in futile protest,
"My God, man, what have you done? What does this mean?"

And then, in a blaze of rage, he was on his feet. Murder was in his
heart as he set himself for a crashing charge that would sweep the
beast from his feet. His own flame-pistol was missing; it was a case of
killing this monster with his bare hands. Tom was circling, over there,
cursing horribly. One of them would get him. Strangely, Antazzo had
lowered the muzzles of his pistols.

A terrific punch, started from the floor, never reached its mark.
Blaine saw a tiny puff of pinkish vapor that spurted from the bosom of
that metallic garment. He was coughing and gasping; helpless. Muscles
refused to do his bidding. With a moan he dropped into the pilot's
seat, knowing that Antazzo's will compelled him. That gas had hypnotic
powers. Mechanically, his fingers strayed to the controls.

And Tom--good old Tommy--he was under the influence of th
