s building," Ronny
protested.

Mouley Hassan said, "No. I've eliminated already everyone who is a citizen
of New Delos. Obviously, Tommy Paine is an alien. We have only forty-eight
Earthlings and other United Planets citizens working here."

He carried the cards to a small collator and worked for a moment on its
controls, as Tog and Ronny watched him with mounting tension. "Let's see,"
he muttered. "We eliminate all women, all those less than forty, all who
haven't done a great deal of travel, those who have been here for several
years."

The end of it was that they eliminated everyone employed in the UP
building.

The cards were stacked back on Mouley Hassan's desk again, and the three
of them sat around and looked glumly at them.

Ronny said, "He's tinkered with the files. He counterfeited fake papers
for himself, or something. Possibly he's pulled his own card and it isn't
in this stack you have."

Mouley Hassan said, "We'll double-check all those possibilities, but
you're wrong. Possibly a few hundred years ago, but not today. Forgery and
counterfeiting are things of the past. And, believe me, the Bureau of
Investigation and especially Section G, may look on the slipshod side, but
they aren't. We're not going to find anything wrong with those cards.
Tommy Paine simply is not working for UP on New Delos."

"Then," Ronny said, "there's only one alternative. He's on this UP ship
going to, what was the name of its destination?"

"Avalon," Mouley Hassan said, his face thoughtful.

Tog said, "Do you have any ideas on the men aboard?"

Mouley Hassan said, "There were four crew men, and six of our agents."

Tog said, "Unless one of them has faked papers, the six agents are
eliminated. That leaves the crew members. Do you know anything about
them?"

Hassan shook his head.

Ronny said, "Let's communicate with Avalon. Tell our representatives there
to be sure that none of the occupants of that ship leaves Avalon until we
get there."

Mouley Hassan said, "Good idea." He turned to his screen and said into it,
"Section G, Bureau of Investigation, on the Planet Avalon."

In moment the screen lit up. An elderly agent, as Section G agents seemed
to go, looked up at them.

Mouley Hassan held his silver badge so the other could see it and on the
Avalon agent's nod said, "I'm Hassan from New Delos. We've just had a
crisis here and there seems to be a chance that it's a Tommy Paine job.
Agent Bronston here is on an
