"The door to this damned place closed," I explained. "_What?_" Before we could recover from the shock, the room filled with a brilliant glare. We turned off our lamps. The room was approximately twelve feet long and nine feet wide. The ceiling was only a few inches above our heads and when I looked at the smooth, hard metal, I felt as if I were trapped in some alien vault. The walls of the room were covered with strange drawings and instruments. Here and there, kaleidoscopic lights pulsed rhythmically. Kane brushed past me and beat his gloved fists against the metal door that had imprisoned us. "Miller!" "Yes?" "See if you can get this thing open from the outside." I knelt before the door and explored its surface with my fingers. There were no visible recesses or controls. Over the intercom network, everyone's breath mingled and formed a rough, harsh sound. I could discern the women's quick, frightened breaths that were almost sobs. Kane's breath was deep and strong; Miller's was faltering and weak. "Miller, get help!" "I'll--" The sound of his breathing ceased. We listened intently. "What happened to him?" "I'll phone Lunar City." My fingers fumbled at the radio controls and trembled beneath the thick gloves. I turned the dials that would connect my radio with Lunar City.... Static grated against my ear drums. _Static!_ * * * * * I listened to the harsh, erratic sound and my voice was weak by comparison: "Calling Lunar City." "Static!" Kane echoed my thoughts. His frown made deep clefts between his eyebrows. "There's no static between inter-lunar radio!" Verana's voice was small and frightened. "That sounds like the static we hear over the bigger radios when we broadcast to Earth." "It does," Marie agreed. "But we wouldn't have that kind of static over _our_ radio, unless--" Verana's eyes widened until the pupils were surrounded by circles of white--"unless we were in outer space!" We stared at the metal door that had imprisoned us, afraid even to speak of our fantastic suspicion. I deactivated my radio. Marie screamed as an inner door opened to disclose a long, narrow corridor beyond. Simultaneous with the opening of the second door, I felt air press against my spacesuit. Before, our suits had been puffed outward by the pressure of air inside. Now our spacesuits were slack and dangling on our bodies. We looked at each other and then at the inviting corridor beyond the open door. We went single file, first Kane, then his wife Marie. Verana followed next and I was the last. We walked slowly, examining the strange construction. The walls were featureless but still seemed alien. At various places on the walls were the outlines of doors without handles or locks. Kane pressed his shoulder against a door and shoved. The door was unyielding.
