Scotty turned, puzzled. "What do you mean?"
"The girls have some kind of plan, and we don't know what it is. If we go barging around in the speedboat, we might throw a monkey wrench into the works."
"But we can't just stand here and do nothing," Scotty said desperately.
"We won't. Go get the plane warmed up and wait for me."
Rick hurried into the house and ran up the stairs to Barby's room. Working fast, he went through the dresser, then through the shelves in her closet. Not finding what he wanted, he paused to look around in case he might have overlooked a possibility.
He didn't know where girls kept things, and he suspected that sometimes the places weren't the same as boys might pick. But he could see no possible place that he hadn't searched.
That meant Barby had her Megabuck unit with her, unless she had left it somewhere else in the house.
He plugged in his earphone and called. "Barby!"
There was no reply. His lips set grimly. No use wasting time here. He ran from the house, hearing the sound of the Sky Wagon as Scotty warmed it up. Joe Blake was not in sight. Rick hurried into the lab and found him watching Professor Morrison who was checking some calculations on the lab's small computing machine.
"Joe, step outside with me for a moment, please."
