Vorthys and the probable-cause crew were now of the opinion that the ore tow had already been in more than one piece at the moment it had struck the mirror, a speculation which had not yet been released to the general public. So had the evidence-destroying explosion of the engines been cause or consequence of that catastrophe? And at what point had those tortured fragments of metal and plastic acquired some of their more interesting distortions?

Miles reran, for the twentieth time that week, the computer’s track of the freighter’s course prior to the collision, and contemplated its anomalies. The ship had carried only its pilot, on a routine-indeed, dead boring-slow run in from the asteroid mining belt to an orbital refinery. The engines had not been supposed to be thrusting at the time of the accident; acceleration had been completed and deceleration was not yet due to begin. The tow ship had been running about five hours ahead of schedule, but only because it had departed early, not because it had boosted hotter than usual. It had been coasting off-course by about six percent, within normal parameters and not yet ready for course correction, though the pilot might have been amusing herself trying to achieve more precision with some unscheduled microboosting. Even with the minor course correction due, the tow ship’s route had been several hundred comfortable kilometers from the soletta array, in fact farther away than if it had been precisely on course.

What the course variation had done was take the freighter’s track almost directly across one of Komarr’s unused worm-hole jump points.
