at she had gone into action, she lay
revealed in the middle of the first zone--at point-blank range.

Instantly the powerful weapons of the _Hyperion_ were brought to bear,
and in the blast of full-driven beams the stranger's screens flamed
incandescent. Heavy guns, under the recoil of whose fierce salvos, the
frame of the giant globe trembled and shuddered, shot out their tons of
high-explosive shell. But the pirate commander had known accurately the
strength of the liner, and knew that her armament was impotent against
the forces at his command. His screens were invulnerable, the giant
shells were exploded harmlessly in mid-space, miles from their
objective. And suddenly a frightened pencil of flame stabbed brilliantly
from the black hulk of the enemy. Through the empty ether it tore,
through the mighty defensive screens, through the tough metal of the
outer and inner walls. Every ether-defence of the _Hyperion_ vanished,
and her acceleration dropped to a quarter of its normal value.

"Right through the battery room!" Bradley groaned. "We're on the
emergency drive now. Our rays are done for, and we can't seem to put a
shell anywhere near her with our guns!"

But ineffective as the guns were, they were silenced forever as a
frightful beam of destruction stabbed relentlessly through the control
room, whiffing out of existence the pilot, gunnery, and lookout panels
and the men before them. The air rushed into space, and the suits of the
three survivors bulged out into drumhead tightness as the pressure in
the room decreased.

Costigan pushed the captain lightly toward a wall, then seized the girl
and leaped in the same direction.

"Let's get out of here, quick!" he cried, the miniature radio
instruments of the helmets automatically taking up the duty of
transmitting speech as the sound disks refused to function. "They can't
see us--our ether wall is still up and their spy-sprays can't get
through it from the outside, you know. They're working from blue-prints,
and they'll probably take your desk next," and even as they bounded
toward the door, now become the outer seal of an airlock, the
annihilating ray tore through the space which they had just quitted in
their flight.

Through the airlock, down through several levels of passengers' quarters
they hurried, and into a lifeboat, whose one doorway commanded the full
length of the third lounge--an ideal spot, either for defense or for
escape outward by means of the m
