Phule Me Twice by Robert Asprin & Peter J. Heck

“And when they do, they’ll swoop down on us like wolves,” said Rafael, wringing his hands.

“Wolves don’t swoop,” barked Tully Bascomb. He headed up the gambling operations, and his years of casino experience had been invaluable to Phule when he agreed to run the Fat Chance. “Pull yourselves together, both of you. We’ve got to come up with an answer to the missing captain before the bad boys do figure out how vulnerable we are. And that means everything’s got to look as if nothing’s changed. Doc, is there anybody on board you’d trust to play the role of Phule until we can get the bot back?”

“Maybe,” said Doc, rubbing his chin. “I’ve got a couple of kids who’re about the right physical type and who are quick studies. With a little makeup…”

“Makeup’s no problem,” said Rex. “With what we’ve got here, I could make Dee Dee look like the captain. What I’m worried about is whether your kids can carry off the stunt when they have to talk to customers-and whether they can be trusted keep the secret.”

“Well, there’s no reason they have to know the whole story,” said Doc. “Outside the board of directors, nobody knows that Phule’s been replaced by an android. The actor replacing the android doesn’t need to know, either. We just tell him the captain’s been called off-station on urgent business.”

“Or maybe he’s sick,” said Tully. “That’ll do for the short run, sure.”

“And as far as the lines, I bet they can do better than the android,” said Doc. “They can have a much wider range of permitted responses without getting in over their heads. And they can handle a lot more random situations than the android could.”
