The human mind can ponder the incredible distances between the stars, but cannot possibly contain within itself a real understanding of them. Marked out on a man’s hand an inch is a large unit of measure. In interstellar space a cubical area with sides a hundred thousand miles long is a microscopically fine division. Light crosses this distance in a fraction of a second. To a ship moving with a relative speed far greater than that of light, this measuring unit is even smaller. Theoretically, it appears impossible to find a particular area of this size. Technologically, it was a repeatable miracle that occurred too often to even be interesting.

Brion and Ihjel were strapped in when the jump-drive cut off abruptly, lurching them back into normal space and time. They didn’t unstrap, but just sat and looked at the dimly distant pattern of stars. A single sun, apparently of fifth magnitude, was their only neighbor in this lost corner of the universe. They waited while the computer took enough star sights to triangulate a position in three dimensions, muttering to itself electronically while it did the countless calculations to find their position. A warning bell chimed and the drive cut on and off so quickly that the two acts seemed simultaneous. This happened again, twice, before the brain was satisfied it had made as good a fix as possible and flashed a NAVIGATION POWER OFF light. Ihjel unstrapped, stretched, and made them a meal.

Ihjel had computed their passage time with precise allowances. Less than ten hours after they arrived a powerful signal blasted into their waiting receiver. They strapped in again as the NAVIGATION POWER ON signal blinked insistently.

A ship had paused in flight somewhere relatively near in the vast volume of space. It had entered normal space just long enough to emit a signal of radio query on an assigned wave length. Ihjel’s ship had detected this and instantly responded with a verifying signal. The passenger spacer had accepted this assurance and gracefully laid a ten-foot metal egg in space. As soon as this had cleared its jump field the parent ship vanished towards its destination, light years away.

Ihjel’s ship climbed up the signal it had received. This signal had been recorded and examined minutely. Angle, strength and Doppler movement were computed to find course and distance. A few minutes of flight were enough to get within range of the far weaker transmitter in the drop-capsule. Homing on this signal was so simple, a human pilot could have done it himself. The shining sphere loomed up, then vanished out of sight of the viewports as the ship rotated to bring the spacelock into line. Magnetic clamps cut in when they made contact.

“Go down and let the bug-doctor in,” Ihjel said. “I’ll stay and monitor the board in case of trouble.”

“What do I have to do?”
