The woman was still reading. Why do women have to dye their hair like that? That color was enough to turn… But on her it worked, somehow. Now, if he just had a cigarette in his hand, he thought, the right words would pop into his mouth automatically. He reached into his pocket.

The moment he whipped out the cigarette case—a present from Boman, which he kept out of friendship, never having owned one before in his life—it felt a little heavier than usual. Just a shade. But heavier it was. Was the ship accelerating, or what?

He strained his ears. Sure enough, the engines were pulling at greater thrust. An ordinary passenger might not have noticed; a series of four-ply insulating bulkheads separated the Titan’s engine room from the ship’s living quarters.

Singling out a pale star in one corner of the window frame, Pirx kept a watchful eye on it. If they’re accelerating, he thought, the star will stay put. But if it so much as jiggles…

It jiggled, drifting slowly, but ever so slowly, to one side.

It’s turning along its longitudinal axis, he reckoned.

The Titan was flying through a “cosmic tunnel,” unobstructed by any dust or meteorites—nothing but empty space. The pilot of the Titan, whose job it was to make sure the giant ship had clear passage, flew on ahead at a distance of 1,900 kilometers. The reason? For safety’s sake—even though, under the terms of an agreement negotiated by the United Astronavigation Association, the Transgalactic Line was granted undisputed right-of-way along its segment of the parabola. And ever since unmanned space probes were used to patrol thousands of transuranic sectors, making it possible for meteorite warnings to be issued as much as six hours in advance, the threat of any external hazards had been all but eliminated. The belt—those billion or so meteorites orbiting between Earth and Mars—was kept under special surveillance, whereas the remnants of any vehicles were bound to pass beyond the ecliptic plane. The progress achieved in this area, even since the time Pirx had been flying patrol, was staggering.
