"Look here," snarled Stutsman, but he stopped when Chambers' hand fell upon his shoulder, gripped it hard.
"Got plenty of air?" asked Greg.
"Air? Sure. Atmosphere machines working perfectly," Craven replied.
"Fine," said Greg. "How about food and water? Plenty of both?"

"Look here, Manning," broke in Chambers, "where's all this questioning leading? What have you got up your sleeve?"
"Just wanted to be sure," Greg told him. "Would hate to have you fellows starve on me, or go thirsty. Wouldn't want to come back and find you all dead."
"Come back?" asked Chambers wonderingly. "I'm afraid I don't understand. Is this a joke of some sort?"
"No joke," said Greg grimly. "I thought you might have guessed. I'm going to leave you here."
"Leave us here?" roared Stutsman.
