But the thought of hurling our bolts at this enemy ship had struck terror into my heart for hours past. I was convinced that the three who in all the world were dearest to me--Anita, Venza, and Snap--were upon that enemy vessel. Grantline asked, "Are you going closer to the Moon?" "No." "The ship couldn't be between us and the Moon. Waters and I have been in the helio room for the past hour, searching with the 'scope there. Nothing doing, Gregg. Not a sign." "I know. Our instruments here show that." "There might be a way of sighting them," Drac put in. "I'll try the Zed-ray," I suggested. "Drac and I have it corrected. But I doubt if it would penetrate the sort of invisibility this enemy would use." Grantline nodded. "Or the Benson curve-light. You think the ship went behind the Moon? Or landed on the Moon?" "It could have done either. Has Waters still got contact with the Earth? Have they seen it?" "No." I made a sudden decision. It would take us two hours at least to make a careful scanning with the Zed-ray; and to take an elaborate series of spectro-heliographs of the Moon's surface, which might show the enemy vessel if it had landed there, was a laborious process. After brief thought, I discarded the idea. "We'll go to the helio room," I told Grantline. "I'm going to try the Benson curve-light." Grantline and I left the turret, heading along the catwalk under the glassite dome toward the helio cubby where the rotund, middle-aged Waters was in charge. It made my heart sink to think of the helio room. Snap should have been there. We crossed the transverse catwalk. The superstructure roof was under us. Farther down, the narrow decks showed with Grantline's men grouped at the firing ports, where his weapons were mounted and ready. As I saw those grouped men loitering on the deck, waiting for me to give them a sighting, I prayed I could do so; and yet there was the shuddering fear that the first blast would bring death to Anita. Waters met us at the door of his cubby. His face was red; he mopped the perspiration from his bald head. "I'm so glad you came! Will you want the Benson-light? I say, I've lost connection with the Earth. I had the Washington transmitter. Five minutes ago they sent me a flash of the Mars and Venus news. They both sent ships, out." He gasped for breath, then added in a rush: "Both the Mars and Venus ships were destroyed and the enemy escaped!" Grantline and I gasped with horror. "Destroyed?" I said. "How?" Waters did not know. The news came; then, immediately after, the Washington transmitter changed its wavelength and he lost connection. "But why, in heaven's name, man, didn't you ring and tell us?" Grantline demanded. "Destroyed--only that! Just destroyed." "I was afraid to leave my instruments," Waters said. "How could I tell? I might be able to renew connections with Washington any minute. Come on in. Do you want to try the Benson curve-light, Mr. Haljan?"
