"You just stay in here?" I asked.
"No, sir," Thomas said. "I check through the whole system. We got three main disposal points and lotsa little ones, an' I have to keep everything operatin'. Otherwise this ship would be in a bad way, Cap'n."
"How did you get in here?" I asked. I looked around the small room. There was only one door, and the tiny space was nearly filled by the gray bulk of the converter unit which broke down wastes into their component elements for reuse.
"I come in through the duct, Cap'n," Thomas said. "I check the ducts every day. You know Cap'n," he said, shaking his head, "they's some bad laid-out ductin' in this here system. If I didn't keep after it, you'd be gettin' clogged ducts all the time. So I jist go through the system and keep her clear."
From somewhere, hope began again. "Where do these ducts lead?" I asked. I wondered how the man could ignore the mutiny going on around him.
"Well, sir, one leads to the mess; that's the big one. One leads to the wardroom, and the other leads up to the Bridge."
My god, I thought, the Bridge.
"How big are they?" I asked. "Could I get through them?"
"Oh sure, Cap'n," Thomas said. "You can get through 'em easy. But are you sure you feel like inspectin' with them busted ribs?"
I was beginning to realize that Thomas was not precisely a genius. "I can make it," I said.
"Cap'n," Thomas said diffidently, "it ain't none o' my business, but don't you think maybe I better get the doctor for ya?"
"Thomas," I said, "maybe you don't know; there's a mutiny under way aboard this ship. The doctor is leading it. I want to get to the Bridge in the worst way. Let's get started."
Thomas looked shocked. "Cap'n, you mean you was hurt by somebody? I mean you didn't have a fall or nothin', you was beat up?" He stared at me with an expression of incredulous horror.
"That's about the size of it," I said. I managed to sit up. Thomas jumped forward and helped me to my feet. Then I saw that he was crying.
"You can count on me, Cap'n," he said. "Jist lemme know who done it, an' I'll feed 'em into my converter."
I stood leaning against the wall, waiting for my head to stop spinning. Breathing was difficult, but if I kept it shallow, I could manage. Thomas was opening a panel on the side of the converter unit.
"It's OK to go in, Cap'n," he said. "She ain't operatin'."
The pull of the two and a half gees seemed to bother him very little. I could barely stand under it, holding on. Thomas saw my wavering step and jumped to help me. He boosted me into the chamber of the converter and pointed out an opening near the top, about twelve by twenty-four inches.
"That there one is to the Bridge, Cap'n," he said. "If you'll start in there, sir, I'll follow up."
I thrust head and shoulders into the opening. Inside it was smooth metal, with no handholds. I clawed at it trying to get farther in. The pain stabbed at my chest.
"Cap'n, they're workin' on the door," Thomas said. "They already been at it for a little while. We better get goin'."
"You'd better give me a boost, Thomas," I said. My voice echoed hollowly down the duct.
Thomas crowded into the chamber behind me then, lifting my legs and pushing. I eased into the duct. The pain was not so bad now.
"Cap'n, you gotta use a special kinda crawl to get through these here ducts," Thomas said. "You grip your hands together out in front of ya, and then bend your elbows. When your elbows jam against the side of the duct, you pull forward."
I tried it; it was slow, but it worked.
"Cap'n," Thomas said behind me. "We got about seven minutes now to get up there. I set the control on the converter to start up in ten minutes. I think we can make it OK, and ain't nobody else comin' this way with the converter goin'. I locked the control panel so they can't shut her down."
That news spurred me on. With the converter in operation, the first step in the cycle was the evacuation of the ducts to a near-perfect vacuum. When that happened, we would die instantly with ruptured lungs; then our dead bodies would be sucked into the chamber and broken down into useful raw materials. I hurried.
I tried to orient myself. The duct paralleled the corridor. It would continue in that direction for about fifteen feet, and would then turn upward, since the Bridge was some fifteen feet above this level. I hitched along, and felt the duct begin to trend upward.
"You'll have to get on your back here, Cap'n," Thomas said. "She widens out on the turn."
I managed to twist over. Thomas was helping me by pushing at my feet. As I reached a near-vertical position, I felt a metal rod under my hand. That was a relief; I had been expecting to have to go up the last stretch the way a mountain climber does a rock chimney, back against one wall and feet against the other.
I hauled at the rod, and found another with my other hand. Below, Thomas boosted me. I groped up and got another, then another. The remaining slight slant of the duct helped. Finally my feet were on the rods. I clung, panting. The heat in the duct was terrific. Then I went on up. That was some shot Kramer had given me.
Above I could see the end of the duct faintly in the light coming up through the open chamber door from the utility room. I remembered the location of the disposal slot on the Bridge now; it had been installed in the small niche containing a bunk and a tiny galley for the use of the duty officer during long watches on the Bridge.
I reached the top of the duct and pushed against the slot cover. It swung out easily. I could see the end of the chart table, and beyond, the dead radar screen. I reached through and heaved myself partly out. I nearly fainted at the stab from my ribs as my weight went on my chest. My head sang. The light from below suddenly went out. I heard a muffled clank; then a hum began, echoing up the duct.
"She's closed and started cyclin' the air out, Cap'n," Thomas said calmly. "We got about half a minute."
I clamped my teeth together and heaved again. Below me Thomas waited quietly. He couldn't help me now. I got my hands flat against the bulkhead and thrust. The air was whistling around my face. Papers began to swirl off the chart table. I kicked loose from the grip of the slot, fighting the sucking pull of air. I fell to the floor inside the room; the slot cover slammed behind me. I staggered to my feet. I pried at the cover, but I couldn't open it against the vacuum. Then it budged, and Thomas's hand came through. The metal edge cut into it, blood started, but the cover was held open half an inch. I reached the chart table, almost falling over my leaden feet, seized a short permal T-square, and levered the cover up. Once started, it went up easily. Thomas's face appeared, drawn and pale, eyes closed against the dust being whirled into his face. He got his arms through, heaved himself a little higher. I seized his arm and pulled. He scrambled through.
I knocked the T-square out of the way and the cover snapped down. Then I slid to the floor, not exactly out, but needing a break pretty bad. Thomas brought bedding from the OD bunk and made me comfortable on the floor.
"Thomas," I said, "when I think of what the security inspectors who approved the plans for this arrangement are going to say when I call this little back door to their attention, it almost makes it worth the trouble."
"Yessir," Thomas said. He sprawled on the deck and looked around the Bridge, staring at the unfamiliar screens, indicator lights, controls.
From where I lay, I could see the direct vision screen. I wasn't sure, but I thought the small bright object in the center of it might be our target. Thomas looked at the dead radar screen, then said, "Cap'n, that there radarscope out of action?"
"It sure is, Thomas," I said. "Our unknown friends blew the works before they left us." I was surprised he recognized a radarscope.
"Mind if I take a look at it, Cap'n?" he said.
