In approximately three weeks, on Saturday, December 9, at 1756 hours GMT, the intruder would collide head-on with Maleiva III.

Maleiva was the infant daughter of the senator who'd chaired the science funding committee when the initial survey was done, two decades earlier. There were eleven planets in the system, but only the doomed third world had received a name to go with its Roman numeral: From the beginning they called it Deepsix. In the often malicious nature of things, it was also one of the very few worlds known to harbor life. Even though locked in a three-thousand-year-old ice age, it would have made, in time, an exquisite new outpost for the human race.

"The collision here is only the beginning of the process," Beekman said. "We can't predict precisely what's going to happen afterward, but within a few thousand years Morgan will have made a complete shambles of this system." He leaned back, folded his hands behind his head, and adopted an expression of complacency. "It's going to be an interesting show to watch."

Beekman was the head of the Morgan Project, a planetologist who had twice won the Nobel, a lifelong bachelor, and a onetime New York State chess champion. He routinely referred to the coming Event as "the collision," but Marcel was struck by the relative sizes of the two worlds. It would most certainly not be a collision. Deepsix would fall into Morgan's clouds, like a coin casually dropped into a pool.

"Why doesn't it have any moons?" he asked Beekman.

Beekman considered the question. "Probably all part of the same catastrophe. Whatever ejected it from its home system would have taken off all the enhancements. We may see something like that here in a few centuries."
