bunk and threw on his slacks and space-jacket. Holk Or was doing the same, the big Jovian's battered green face almost ludicrous in astonishment.

"Now perhaps you'll tell us what this means," Kenniston said harshly, his mind racing. "Have you lost your senses?"

"I've just come to them, Kenniston," rapped Murdock. "What fools we all were, not to guess that you two belong to Dark's pirates!"

Kenniston's lips tightened. It was clear now that Murdock had actually discovered something. From Holk Or came an angry roar.

"Devils of Pluto, I'm no pirate!" the big Jovian lied magnificently. "Whatever gave you this crazy idea?"

Murdock's hard face did not relax. He waved the atom-pistol. "Go into the main cabin," he ordered. "Walk ahead of me."

Helplessly, Kenniston and Holk Or obeyed. His mind was desperate as he shouldered down the corridor. The throbbing of the rockets told him the Sunsprite was still forging through the void. They must be very near Vesta by now—and now this had to happen!

The others had been awakened by the uproar and streamed into the main cabin after Murdock and his two prisoners. Kenniston glimpsed Gloria, slim in a silken negligee, her dark eyes round with amazement.

"Hugh, have you gone crazy?" she exclaimed stupefiedly.

Murdock answered without looking toward her. "I've found out the truth, Gloria. These men belong to John Dark's crew. They were taking us into a trap."

"Holy smoke!" gasped Robbie Boone, his jaw sagging as the chubby youth stared at Kenniston and Holk Or. "They're pirates?"

"I think you must be losing your mind!" Gloria stormed at Hugh Murdock. "This is ridiculous."

Holk Or yawned elaborately. "Space-sickness hits people in queer ways, Miss Loring," the Jovian told Gloria confidentially. "Some it just makes sick, but others it makes delirious."

"I'm not delirious, and you two know it," Murdock retorted grimly. He spoke to Gloria and the others, without taking his eyes or the muzzle of his pistol off his two captives.

"I thought from the first that this Kenniston's story of finding the wreck of Dark's ship on Vesta was a thin one," Murdock declared. "And yesterday my suspicions were increased when I went down and looked over the cargo of equipment they brought. It's not equipment to dig out a buried wreck. It's equipment to repair a damaged ship—John Dark's ship!

"Suspecting that, last 'night' I sent a telaudiogram to Patrol headquarters at Earth. I gave full descriptions of Kenniston and this Jovian and inquired if they had criminal records. An answer came through an hour ago. This fellow Holk Or has a record of criminal piracy as long as your arm, and was definitely known to be one of John Dark's crew!"

There was an incredulous gasp from the others. Murdock still grimly watched Kenniston and the Jovian as he concluded.

"The Patrol hasn't yet sent through Kenniston's record, but it's obvious enough that he's one of Dark's men too, and that his story that he and the Jovian are meteor-miners is a flat lie."

"I can't understand this," muttered young Arthur Lanning, staring. "If they're Dark's men, why should they induce us to go to Vesta?"

"Can't you see?" said Hugh Murdock. "John Dark's ship did crash on Vesta after being wrecked—that must be true enough. But Dark and his pirates weren't dead as the Patrol thought. They had to have machines and material to repair their ship. So Dark sent these two men to Mars for the materials. The two couldn't get a ship there any other way, so they made use of our cruiser by selling us that treasure yarn!"
