Sam Catlin, watching out the window, said in a tight voice, "Why not ask him yourself?"
"Eh?"
"Ask him for yourself! There he is—outside, riding some kind of critter...."
"It's a ghost," whispered Frayberg. "A man without a space-suit.... There's no such thing!"
"He sees us.... Look...."
Murphy was staring at them, and his surprise seemed equal to their own. He waved his hand. Catlin gingerly waved back.
Said Frayberg, "That's not a horse he's riding. It's a combination ram-jet and kiddie car with stirrups!"
"He's coming aboard the ship," said Catlin. "That's the entrance port down there...."
Wilbur Murphy sat in the captain's stateroom, taking careful breaths of air.
