Nina's brother! My S.S. boss had mentioned him; mysteriously he had disappeared. He was loosening the wires which bound me; and his swift whispers told me: Like his father, he had wanted to get secretly to the Moon. Throughout all the mutiny he had had no opportunity of doing anything which seemed better than posing as one of the villains. Only once had he had any chance to communicate with Nina--that time when he had gone to her room, telling her that he was going to try and kill Mokk and Torio before the attack started, and thus ward it off. And that he had not been able to do. He was only a boy really, barely twenty; he was trembling with eagerness and excitement now as he cast me loose and I rose up out of the bunk and stood beside him. "You armed?" I whispered. "No; only this knife. I've tried to get something else but can't." "Any of the crew with weapons?" "No, I don't think so. Knives, machinery bars and things like that. Mokk and Torio seemed to have everything." "How many in the crew?" "Five, and me. One got killed in the fight. Another wounded. There were two or three others planted among the passengers. Maybe more. They got killed, too. Oh, what shall we do? All I could think of was to get here and release you." "And I damn well thank you, Jim." I clapped him on the back. "Look here, you keep the knife. Heaven knows you may need it." "What are we going to do?" he whispered eagerly. "Is--is Nina all right?" "Yes, I guess so. Up in the turret. Have you seen Mokk?" "That Martian? No. What can we do?" Certainly I had no very clear idea. Five men, and Mokk and Torio. They were not very many to be dispersed about the ship, and we had a fair chance of cautiously moving around without encountering any of them. Torio, I figured, was still in the chart room, with Nina and Mackensie. Mokk, perhaps, was asleep somewhere. Young Blake had no very clear idea of where the other five might be. "Come on," I whispered. "Let's take a look at the chart room." If by any wild chance we could overcome Torio and get the electric weapons-- We got up to the roof deck without encounter. From one of the midships ladders I stared forward to the chart room. I could see Torio and Mackensie still in there, at the table with the charts. And now, beside the chart room, where he could command its door and also the control turret, a huge blob was lurking. Was it Mokk? It wasn't. I made the figure out more clearly as he moved a trifle. "That's one of the crew," Blake whispered. "Look--he's got a ray-gun." I could see it. I turned back. "Got to try something else. The midships keel pressure porte," I whispered. "Ever been down there, Jim?" He stared. "No. What's your idea? Pressure porte?" "There's also a pressure porte in the dome, just over the control turret. If we can get some Erentz pressure suits down in the keel--"
