Regin Naylo faced his superior with a scowl. "That rips it wide open,"

he said.

Viggon Sarri smiled confidently. He glanced at Linus Brein and asked,

"Just how competent do you think this new thing is?"

Linus shrugged. "We've analyzed the infrawave pattern they've

developed. It is obvious that this is their first prototype of an

infrawave space detector. The pattern is of the primitive absorptive

type, which is both inefficient as a detector and is also inclined to

produce spurious responses. From our observations, their equipment

must be extremely complex too. It must be loaded to the scuppers with

fragile circuits and components, because the search pattern keeps

breaking down, or becoming irregular. An efficient detector cannot

be made of the infrawave bands until the third order of reflective

response is discovered. I doubt that any research team, no matter how

big, can start with the primitive absorption phase of the infrawaves

and leap to the higher orders of infrawave radiation in less than a

lifetime of study."

"So, gentlemen?" asked Viggon of his two aides. "Can you predict

whether or not their new detector will deliver the goods?"

All looked expectantly at Linus Brein.

"We've been recalculating our probabilities at the introduction of each

new phase of their behaviour," Linus Brein said seriously. "From their

actions, I would say that they do not know, grasp, or perhaps even

guess that space has flaws and warps in the continuum. They have been

going at their search in a pattern of solid geometrical precision, but

have been paying no attention to those rifts, small as they are, that

actually make a straight course bend aside for a distance. So due to

the fact that their search pattern has already passed over one of these

rifts in which the one lifeship lies, and passed beyond in their line

of search, we have produced a nine-nines probability that they will not

locate this lifeship."

"And the other?" prompted Viggon Sarri, with interest.

"I'm not done with the first yet," Linus Brein said quietly. "There

remains the random search group. Therein lies the eight-oughts-one

positive probability."

Viggon snorted. "I call ten to the minus ten chances rather hopeless.

But go on, Linus."

"The other has a sixty-forty chance," he said. "If the infrawave

detector locates the space rift that lies along our coordinate three

seventy-six, when the ship is near seven sixty-seven, then the scout

craft will pass within magnetic detection range of the lifeship. That's

a lot of 'ifs', I know, but they add up to a sixty-forty chance. I

say this because space rifts tend to produce strong responses in any

of the primitive detecting gear. They've certainly been busy running

down space warps, which indicates that they've been getting a lot

of spurious responses." He smiled. "If space were entirely clear of

foreign matter and space rifts, they'd find their new detector vaguely

inefficient. I--"

Viggon waved a hand to indicate he had heard enough.

"Gentlemen," he said quietly. "I've been criticized for waiting, but

what one man calls study the other man calls timidity. We'll continue

to wait for the final factor. Then we'll know...."

The stereo pattern in the Information Center of Commodore Ted Wilson's

flagship was slowly being filled with the hazy white that indicated

that these volumes had been combed carefully. As he watched, he could

see how the search was progressing, and it was painfully obvious that

the search was not going good at all.

The flights of spacecraft in set patterns back and forth through the

stereo had covered nearly all of the truncated space cone. The random

search ships were slowly cutting secondary lines through the regions

already covered. There was a green sphere combing the stereo pattern

now, indicating the new infrawave detector ship and its expected volume

of detector coverage.

Space was filled to overflowing with the fast patter of the

communications officers, using infrawave for talks between flights, and

ordinary radio for talks between ships of the same flight.

Wilson had appointed Chief Communications Officer Haggerty to police

the bands. Haggerty had done a fine job, removing the howling confusion

and interference caused from too many calls on the same channel. But

the result was still a high degree of constant call and reply and

cross talk. Most of the chatter came from the infrawave detector ship,

sending the scout craft flitting hither and thither on the trail of

spurious responses.

It was almost impossible to grasp the extent of the operation. Only in

the stereo pattern could anybody begin to follow the complex operation,

and those who watched the stereo knew that their pattern was only an

idealized space map of what they hoped was going on.

It was worse than combing the area of an ocean from maps that contained

a neat grid of cross rules. Much worse. For the uncharted ocean is

gridded with radio location finders so accurate that the position of

two ships a hundred yards apart shows a hundred yards of difference in

absolute position in the loran.

Some day in the distant future space would be solid-gridded with

infrawave navigation signals. Then the space coordinates of any

spacecraft could be found to a fine degree of precision. But now all

that Wilson and his nav-techs could do was to keep sighting the fixed

stars, and from them compute their position.

This sort of space navigation was good enough to keep a ship on course,

but far from precise enough to pinprick a true position. But, after

all, a crude positioning in the middle of interstellar space is good

enough. One literally has cubic light years to float around in. Once

the spacecraft begins to approach a destination, the space positioning

can be made.

Again, few spacecraft pause in mid-flight between stars long enough to

care about their interstellar position. After all, space flight does

provide a mode of travel where the destination lies within eyesight.

Or rather, it has lain within eyesight ever since it became commonly

accepted that these ultimate destinations were places, instead of holes

poked in an inverted ceramic bowl.

Then, in the middle of the communications confusion, came a call from

one of Commander Hatch's scout flights.

"Pilot Logan, Flight Eighteen, to Commander Hatch. Report."

"Hatch to Logan. Go ahead. Find something, Will?"

Will Logan said, "Solid target detected on radar, Commander. Approached

and found. I am now within five thousand yards of what appears to be

Lifeship One."

The entire fleet went silent, except for the detector ship, the scout

craft, and Wilson's flagship.
