ks bad, sir. One
might be an accident; two might possibly be a coincidence...." His voice
died away. What might that coincidence mean?

"But at three it would get to be a habit," the captain finished the
thought. "And whatever happened, happened quick. Neither of them had
time to say a word--their location recorders simply went dead. But of
course they didn't have our detector screens nor our armament. According
to the observatories we're in clear ether, but I wouldn't trust them
from Tellus to Luna. You have given the new orders, of course?"

"Yes, sir. Detectors full out, all three courses of defensive screen on
the trips, projectors manned, suits on the hooks. Every object detected
in the outer space to be investigated immediately--if vessels, they are
to be warned to stay beyond extreme range. Anything entering the fourth
zone is to be rayed."

"Right--we are going through!"

"But no known type of vessel could have made away with them without
detection," the second officer argued. "I wonder if there isn't
something in those wild rumors we've been hearing lately?"

Battle was coming into being; a formation developed during
the Jovian Wars while the forces of the Three Planets were
fighting in space.]

"Bah! Of course not!" snorted the captain. "Pirates in ships faster than
light--fifth order rays--nullification of gravity--mass without
inertia--ridiculous! Proved impossible, over and over again. No, sir, if
pirates are operating in space--and it looks very much like it--they
won't get far against a good big battery full of kilowatt-hours behind
three courses of heavy screen, and a good solid set of multiplex rays.
Properly used, they're good enough for anybody. Pirates, Neptunians,
angels, or devils--in ships or on sunbeams--if they tackle the
_Hyperion_ we'll burn them out of the ether!"

Leaving the captain's desk, the watch officer resumed his tour of duty.
The six great lookout plates into which the alert observers peered were
blank, their far-flung ultra-sensitive detector screens encountering no
obstacle--the ether was empty for thousands upon thousands of
kilometers. The signal lamps upon the pilot's panel were dark, its
warning bells were silent. A brilliant point of white in the center of
the pilot's closely ruled micrometer grating, exactly upon the
cross-hairs of his directors, showed that the immense vessel wa
