"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?"
