A fragment of Old Testament verse has been running through my mind—from Ecclesiastes, I think. I don't remember it verbatim, but it's something like this:

To every thing there is a season, and a time to every purpose under heaven: A time to weep, and a time to laugh; a time to mourn, and a time to dance; A time to get, and a time to lose; a time to keep, and a time to cast away; A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted.

For me, anyway, I feel that the time has come. Perhaps it is not to die but something else, less final or more terrible.

In any case, you will remember, I know, what we decided long ago—that a man owes one of two things to his planet, to his race: posterity, or himself. I could not contribute the first—it is only proper that I should offer the second and not shrink if it is accepted....

—From a letter by Peter Hoskins to his wife.

In the quiet and the dark, Hoskins moved.

"Checkmate," he said.

He rose from his chair and crossed the cabin. Ignoring what was on the table, he opened a drawer under the parts cabinet and took out a steel rule. From a book rack he lifted down a heavy manual. He sat on the end of the couch with the manual on his knees and leafed through it, smoothing it open at a page of physical measurements. He glanced at the floor, across it to the black curtain, back to the one exposed bulkhead. He grunted, put the book down, and carried his tape to the steel wall. He anchored one end of it there by flipping the paramagnetic control on the tape case, and pulled the tape across the room. At the blackness he took a reading, made a mark.

Then he took a fore-and-aft measurement from a point opposite the forward end of the table to one opposite the after end of the bunk. Working carefully, he knelt and constructed a perpendicular to this line. He put the tape down for the third time, arriving again at the outboard wall of darkness. He stood regarding it thoughtfully, and then unhesitatingly plunged his arm into it. He fumbled for a moment, moving his hand around in a circle, pressing forward, trying again. Suddenly there was a click, a faint hum. He stepped back.

Something huge shouldered out of the dark. It pressed forward toward him, passed him, stopped moving.
