How much of this is true, no one really knows. What is on the record, however, is that Morgan had been both hated and feared by his colleagues and apparently by a deranged brother-in-law who made at least two attempts to kill him. When he'd died, finally, of heart failure, his onetime friend and longtime antagonist Gunther Beekman, commented privately that he had beaten his second wife to the punch. In accordance with his instructions, no memorial was conducted. It was, some said, his last act of vindictiveness, denying his family and associates the satisfaction of staying home.

Because he had done the orbital work and predicted the coming collision, the Academy had given his name to the rogue world that had invaded the Maleiva system. Although that was a gesture required by tradition in any case, many felt that the Academy directors had taken grim pleasure in their action.

Morgan's World approached Jovian dimensions. Its mass was 296 times that of Earth. Diameter at the equator was 131,600 kilometers, at the poles about five percent less. This oblateness resulted from a rotational period of just over nine hours. It had a rocky core a dozen times as massive as the Earth. It was otherwise composed primarily of hydrogen and helium.

It was tilted almost ninety degrees to its own plane of movement, and half as much to the system plane. It was a gray-blue world, its atmosphere apparently placid and untroubled, with neither rings nor satellites.

"Do we know where it came from?" Marcel asked.

Gunther Beekman, small, bearded, overweight, was seated beside him on the bridge. He nodded and brought up a fuzzy patch on the auxiliary display, closed in on it, and enhanced. "Here's the suspect," he said. "It's a section of the Chippewa Cloud, and if we're right, Morgan's been traveling half a billion years."
