Ross was too tired to protest. They changed places, and he curled up as best he could on his small share of seat. Only now that he was free to sleep, he realized he no longer wanted to. Kurt must have thought Ross had fallen asleep, for after perhaps two miles of steady grinding along, he moved cautiously behind the wheel. Ross saw by the trace of light from the instrument panel that his companion was digging into the breast of his parka to bring out a small object which he held against the wheel of the cat with one hand, while with the other he tapped out an irregular rhythm.

To Ross the action made no sense. But he did not miss the other's sigh of relief as he restored his treasure to hiding once more, as if some difficult task was now behind him. Shortly afterward the cat ground to a stop, and Ross sat up, rubbing his eyes. "What's the matter? Engine trouble?"

Kurt had folded his arms across the wheel. "No. It is just that we are to wait here——"

"Wait? For what? Kelgarries to come along and pick us up?"

Kurt laughed. "The major? How I wish that he would arrive presently. What a surprise he would receive! Not two little mice to be put back into their cages, but the tiger cat, all claws and fangs!"

Ross sat up straighter. This now had the bad smell of a frame, a frame with himself planted right in the middle. He figured out the possibilities and came up with an answer which would smear Ross Murdock all over any map. If Kurt were waiting to meet friends out here, they could only be of one brand.

For most of his short life Ross had been engaged in a private war against the restrictions imposed upon him by a set of legal rules to which something within him would not conform. And he had, during those same years filled with attacks, retreats, and strategic maneuvering, formulated a code of rules by which to play his dangerous game. He had not murdered, and he would never follow the path Kurt took. To one who was supremely impatient of restraint, the methods and aims of Kurt's employers were not only impossibly fantastic and illogical—they were to be opposed to the last ounce of any man's energy.

"Your friends late?" He tried to sound casual.

"Not yet, and if you now plan to play the hero, Murdock, think better of it!" Kurt's tone held the crack of an order—that note Ross had so much disliked in the major's voice. "This is an operation which has been most carefully planned and upon which a great deal depends. No one shall spoil it for us now——"

"The Reds planted you on the project, eh?" Ross wanted to keep the other talking to give himself a chance to think. And this was one time he had to think, clearly and with speed.
