When they were at last in space, Terra-bound, Gregor said, "That was a very handsome job of detection."
"It was nothing," Arnold said modestly. "You would have figured it out yourself in a few months."
"Thanks. And it was very nice of you, speaking up for Edward the way you did."
"Well, Myra was a bit strong-minded for me," Arnold said. "And a trifle provincial. I am, after all, a creature of the great cities."
"It was still an extremely decent thing to do."
Arnold shrugged.
"The trouble is, how will Myra and Edward solve this planet problem? Neither seems the type to give in."
"Oh, that's as good as solved," Gregor said offhandedly.
"What do you mean?"
"Why, it's obvious," Gregor said. "And it fills the one gaping hole in your otherwise logical reconstruction of events."
"What hole? What is it?"
"Oh, come now," Gregor said, enjoying his opportunity to the utmost. "It's apparent."
"I don't see it. Tell me."
"I'm sure you'll figure it out in a few months. Think I'll take a nap."
"Don't be that way," Arnold pleaded. "What is it?"
"All right. How tall was Jameson's electronic Scarb, the one that frightened Myra?"
"About nine feet."
"And how tall was Edward, disguised as a Scarb?"
"About six feet tall."
"And the Scarb we saw in our bedroom, the one we shot at—"
"Good Lord!" Arnold gasped. "That Scarb was only four feet tall. We have one Scarb left over!"
"Exactly. One Scarb that no one produced artificially, and that we can't account for — unless Coelle actually is haunted."
"I see what you mean," Arnold said thoughtfully. "They'll have to move to Kerma. But we didn't really fulfill our contract."
"We did enough," Gregor said. "We decontaminated three distinct species of Skag — produced by Jameson, Olson, and Edward. If they want a fourth species taken care of, that'll be a separate contract."
"You're right," Arnold said. "It's about time we became businesslike. And it's for their own good. Something has to make up their minds for them." He thought for a moment. "I suppose they'll leave Coelle to Transstellar Mining. Should we tell Olson that the planet is really haunted?"
"Certainly not," Gregor said. "He'd just laugh at us. Have you ever heard of ghosts frightening an automatic mining machine?"
