"My heart trusted you--believed in you; and because it was my heart, I mistrusted. I followed my reason instead--and no woman should do that." "I'm following my heart--have from the beginning," Barry murmured. "And it tells me we haven't lost yet." His hands left her elbows, went about her waist. Behind them, the Martian turned away. "_Revolt of Martian savages_," broke in a voice from the radio. They froze, listening to the words that followed; "_Craig Grey, President of Grey Enterprises, Incorporated, is present in person at the scene of trouble, directing the heroic resistance of Terrestrial pioneers. He has been authorised by World Government to capture Barry Williams, investigator of the dastardly campaign, dead or alive._ "_Williams disappeared into the desert, and the abortive attack by the savages followed immediately. 'Justice in the Crypt', is said to be the wild battle shout of the Martians. Federal troops have embarked for Mars. It is--_" Barry snapped off the radio. "Grey has pulled off another one!" Deisanocta clung to his hand mutely, her white face revealing the despair the news had brought. Barry's mouth was a straight, hard line. His eyes flamed, and muscles bunched in his shoulders. After a moment's silence, he turned the radio back on. "More orders for you, Deisanocta. Get in touch with your men. We want about half a dozen of the best, and tell them to bring along the oldest Martian they can find!" "But what--why?" "If it's 'Justice from the Crypt' they want, we'll give it to them. We're going to find out what's there, and use it! "Have your men meet us near one entrance to the place. Tell them to bring a portable visa-radio, so we can call the rest if we need them. This is the only chance we've got left!" V Over the red sands of Mars, the silver mist of vengeance was slowly thinning. The two moons sent their light probing down, breaking through here and there to find and bathe the sand. Where those rays found the little party that crept cautiously toward the Crypt, it did not betray them under the red camouflage blankets. They moved silently ahead, invisible, determined. "We are there," Deisanocta whispered at last to Barry Williams, beside her under the cloak. "We must rise and go on foot the rest of the way." "O.K." he said. He scoured the sky, his sharp blue eyes trying to pierce the mist. "If any ships come over, they won't spot us. The mist is thick here. "The trick will be to get by the guard at the entrance. We don't want to have to overcome him and risk an alarm." Deisanocta was speaking to the Martians. They rose with Barry and the Princess, and the little party stayed close together to avoid being separated in the white shroud about them. A suggestion from Barry, and they formed into single file and moved forward. A sharp-eyed Martian was in the lead. "We are fortunate," the Princess said. "The guard is away from his post."
