Crain's eyes fell on Krell. "But what's he doing here?" he exclaimed. Kent briefly explained Jandron's treachery toward Krell, and Crain's brows drew ominously together.

"So Jandron put you here with us! Krell, I am a commissioned captain of a space-ship, and as such can legally try you and sentence you to death here without further formalities."

Krell did not answer, but Kent intervened. "There's hardly time for that now, sir," he said. "I'm as anxious to settle with Krell as anyone, but right now our main enemy is Jandron, and Krell hates Jandron worse than we do, if I'm not mistaken."

"You're not," said Krell grimly. "All I want right now is to get within reach of Jandron."

"There's small chance of any of us doing that," Crain told them. "There's not a single space-helmet on the Martian Queen."

"You've searched?" Liggett asked.

"Every cubic inch of the ship," Crain told him. "No, Jandron's men made sure there were no helmets left here, and without helmets this ship is an inescapable prison."

"Damn it, there must be some way out!" Kent exclaimed. "Why, Jandron and his men must be starting to pump that fuel into the Pallas by now! They'll be sailing off as soon as they do it!"

Crain's face was sad. "I'm afraid this is the end, Kent. Without helmets, the space between the Martian Queen and the Pallas is a greater barrier to us than a mile-thick wall of steel. In this ship we'll stay, until the air and food give out, and death releases us."

"Damn it, I'm not thinking of myself!" Kent cried. "I'm thinking of Marta! The Pallas will sail out of here with her in Jandron's power!"
