your purposes and I to mine. Now give me one of those projectors. And set it to predispose a situation I am about to specify to you. Take however long it needs. The audience is a patient one." He laughed, and tears gathered in his eyes. Mr. Ermine waited, isolated from the cold, listening to hear whether the rifle stock was slipping out of his fingers. He had no desire to go into the Martian building after Sollenar and involve third parties. All he wanted was to put Sollenar's body under a dated marker, with as little trouble as possible. Now and then he walked a few paces backward and forward, to keep from losing muscular control at his extremities because of low skin temperature. Sollenar must come out soon enough. He had no food supply with him, and though Ermine did not like the risk of engaging a man like Sollenar in a starvation contest, there was no doubt that a man with no taste for fuel could outlast one with the acquired reflexes of eating. The door opened and Sollenar came out. He was carrying something. Perhaps a weapon. Ermine let him come closer while he raised and carefully sighted his rifle. Sollenar might have some Martian weapon or he might not. Ermine did not particularly care. If Ermine died, he would hardly notice it—far less than he would notice a botched ending to a job of work already roiled by Sollenar's break away at the space field. If Ermine died, some other SPRO agent would be assigned almost immediately. No matter what happened, SPRO would stop Sollenar before he ever reached Abernathy Field. So there was plenty of time to aim an unhurried, clean shot. Sollenar was closer, now. He seemed to be in a very agitated frame of mind. He held out whatever he had in his hand. It was another one of the Martian entertainment machines. Sollenar seemed to be offering it as a token to Ermine. Ermine smiled. "What can you offer me, Mr. Sollenar?" he said, and shot. The golden ball rolled away over the sand. "There, now," Ermine said. "Now, wouldn't you sooner be me than you? And where is the thing that made the difference between us?" He shivered. He was chilly. Sand was blowing against his tender face, which had been somewhat abraded during his long wait. He stopped, transfixed.
