Cain was right. The alien was capable of Transition. And he obviously had little fear of the Rim. His ship grew larger in the scanner.

Mason felt his fingers grow cold again.


ance told the girl to eject the tape of co-ordinates from the nav-computers, and he took over manually, hoping the comps would keep up. It would be up to him where they went, and up to the comps to keep track of the Scout's position relative to both the Solar System and the Explorer.

His fingers played across the control-banks as though they were the keyboards of a great organ, and he felt his insides writhe as he slipped the hurtling ship back into E-Space, then back to R-level again. He played the tiny craft between levels as though it were a stone skipping across water, and altered course with each Transition with no attempt at plan or pattern. Rivulets of ice water trickled down across his ribs, and the flesh of his thin face was stiff.

"Wrong again," he heard Cain saying. "At least we can tell the brain trust that their precious R-factor is constant beyond the Rim ... maybe that'll be worth a buck or two. At least those kids back there are playing around in this galaxy like it was their own front yard. Go on, skipper, take a look yourself!"

Mason didn't have to look. He knew that he hadn't lost the alien; had known somehow that he wouldn't be able to. Too apparently, their own galaxy, near as it was to the Milky Way, was of the same Space, its continuum forged in the same curvature matrices.

"Shall I order our m-guns placed, sir?" It was Judith, and he knew she had grasped the implications of the situation as quickly as she always did. Sometimes he wondered if she were a computer herself, clad in the graceful body of a young woman rather than in a shell of permasteel. And other times....

He didn't even think about his answer. The "No" was automatic.
