Time for coffee, Trimble thought, responding unconsciously to a dry throat plus a fuzziness of the mouth plus slight fatigue. He set his hands to stand up, and— The image came to him in an endless row of Trimbles, lined up like the repeated images in facing mirrors. But each image was slightly different. He would go get the coffee and he wouldn't and he would send somebody for it, and someone was about to bring it without being asked. Some of the images were drinking coffee, a few had tea or milk, some were smoking, some were leaning too far back with their feet on the desks (and a handful of these were toppling helplessly backward), some were, like this present Trimble, introspecting with their elbows on the desk. Damn Crosstime anyway.
He'd have had to check Harmon's business affairs, even without the Crosstime link. There might have been a motive there, for suicide or murder, though it had never been likely.
In the first place, Harmon had cared nothing for money. The Crosstime group had been one of many. At the time that project had looked as harebrained as the rest: a handful of engineers and physicists and philosophers determined to prove that the theory of alternate time tracks was reality.
In the second place, Harmon had no business worries.
Quite the contrary.
Eleven months ago an experimental vehicle had touched one of the worlds of the Confederate States of America and returned. The universes of alternate choice were within reach. And the pilot had brought back an artifact.
From that point on, Crosstime travel had more than financed itself. The Confederate world's "stapler," granted an immediate patent, had bought two more ships. A dozen miracles had originated in a single, technologically advanced timeline, one in which the catastrophic Cuban War had been no more than a wet firecracker. Lasers, oxygen-hydrogen rocket motors, computers, strange plastics—the list was still growing. And Crosstime held all the patents.
In those first months the vehicles had gone off practically at random. Now the pinpointing was better. Vehicles could select any branch they preferred. Imperial Russia, Amerindian America, the Catholic Empire, the dead worlds. Some of the dead worlds were hells of radioactive dust and intact but deadly artifacts. From these worlds Crosstime pilots brought strange and beautiful works of art, which had to be stored behind leaded glass.
The latest vehicles could reach worlds so like this one that it took a week of research to find the difference. In theory they could get even closer. There was a phenomenon called "the broadening of the bands".
And that had given Trimble the shivers.
When a vehicle left its own present, a signal went on in the hangar, a signal unique to that ship. When the pilot wanted to return, he simply cruised across the appropriate band of probabilities until he found the signal. The signal marked his own unique present.
Only it didn't. The pilot always returned to find a clump of signals, a broadened band. The longer he stayed away, the broader was the signal band. His own world had continued to divide after his departure, in a constant stream of decisions being made both ways.
Usually it didn't matter. Any signal the pilot chose represented the world he had left. And since the pilot himself had a choice, he naturally returned to them all. But— There was a pilot by the name of Gary Wilcox. He had been using his vehicle for experiments, to see how close he could get to his own timeline and still leave it. Once, last month, he had returned twice.
Two Gary Wilcoxes, two vehicles. The vehicles had been wrecked—their hulls intersected. For the Wilcoxes it could have been sticky, for Wilcox had a wife and family. But one of the duplicates had chosen to die almost immediately.
Trimble had tried to call the other Gary Wilcox. He was too late. Wilcox had gone skydiving a week ago. He'd neglected to open his parachute.
Small wonder, thought Trimble. At least Wilcox had had motive. It was bad enough, knowing about the other Trimbles, the ones who had gone home, the ones drinking coffee, et cetera. But—suppose someone walked into the office right now, and it was Gene Trimble?
It could happen.
Convinced as he was that Crosstime was involved in the suicides, Trimble—some other Trimble—might easily have decided to take a trip in a Crosstime vehicle. A short trip. He could land here.
Trimble closed his eyes and rubbed at the corners with his fingertips. In some timeline, very close, someone had thought to bring him coffee. Too bad this wasn't it.
It didn't do to think too much about these alternate timelines. There were too many of them. The close ones could drive you buggy, but the ones farther off were just as bad.
Take the Cuban War. Atomics had been used, here, and now Cuba was uninhabited, and some American cities were gone, and some Russian. It could have been worse.
Why wasn't it? How could we luck out? Intelligent statesmen? Faulty bombs? A humane reluctance to kill indiscriminately?
No. There was no luck anywhere. Every decision was made both ways. For every wise choice you bled your heart out over, you had made all the other choices too. And so it went, all through history.
Civil wars unfought on some worlds were won by either side on others. Elsewhen, another animal had first done murder with an antelope femur. Some worlds were still all nomad; civilization had lost out. If every choice was canceled elsewhere, why make a decision at all?
Trimble opened his eyes and saw the gun.
That gun, too, was endlessly repeated on endless desks. Some of the images were dirty with years of neglect. Some smelled of gunpowder, fired recently, a few at living targets. Some were loaded. All were as real as this one.
A number of these were about to go off by accident.
A proportion of these were pointed, in deadly coincidence, at Gene Trimble.
See the endless rows of Gene Trimble, each at his desk. Some were bleeding and cursing as men run into the room following the sound of the gunshot. Many are already dead.
Was there a bullet in there? Nonsense.
He looked anyway. The gun was empty.
Trimble loaded it. At the base of his mind he felt the touch of the handle. He would find what he was seeking.
He put the gun back on his desk, pointing away from him, and he thought of Ambrose Harmon, coming home from a late night. Ambrose Harmon, who had won five hundred dollars at poker. Ambrose Harmon, exhausted, seeing the lightening sky as he prepared for bed. Going out to watch the dawn.
Ambrose Harmon, watching the slow dawn, remembering a two-thousand-dollar pot. He'd bluffed. In some other branching of time, he had lost.
Thinking that in some other branching of time, that two thousand dollars included his last dime. It was certainly possible. If Crosstime hadn't paid off, he might have gone through the remains of his fortune in the past four years. He liked to gamble.
Watching the dawn, thinking of all the Ambrose Harmons on that roof. Some were penniless this night, and they had not come out to watch the dawn.
Well, why not? If he stepped over the edge, here and now, another Ambrose Harmon would only laugh and go inside.
If he laughed and went inside, other Ambrose Harmons would fall to their deaths. Some were already on their way down. One changed his mind too late, another laughed as he fell.
Well, why not?
Trimble thought of another man, a nonentity, passing a firearms store. Branching of timelines, he thinks, looking in, and he thinks of the man who took his foreman's job. Well, why not?
