Randall withdrew a little. "Don't you trust me?" he asked in a hurt tone. "I'll pay you if he doesn't vanish."

"Shhh," Von Juntz said. We crowded around the screen again.

The screen looked down on the bar from above and behind it, like looking in through a window set above the mirror. And at the bar was only one solitary customer, a tall lean man in a frock coat and plug hat with a cigar from which smoke curled richly, and a schooner of beer before him. He looked up at the bar mirror, and we saw a lean, evilly humorous face with the Pangborn features clearly marked on it. "Grandpa," Von Juntz whispered.

In a dark angle of the place, Pangborn himself materialized from the machine. We saw a glimmer as he raised the gun.

"See," Von Juntz whispered. "He has forgotten to uncock the safety. Now he has. Now he creeps closer. Soon now we shall know the paradox."

Grandpa Pangborn had put down his cigar. His hand had slid under the lapel of his frock coat. Just before he whirled, I realized that he had been watching Pangborn in the mirror all the time.

He whirled, his hand whipped out from beneath his lapel, and the sound of a gunshot echoed in the saloon. We had a clear view of the angry surprise on Pangborn's face before he toppled nose down into the sawdust. He was quite obviously dead.

"Whippersnapper," Grandpa Pangborn muttered. He holstered his gun and looked up, and his lean face oddly seemed to be looking straight into the peering eye of the time viewer, and into our staring eyes. We could not be seen.... Or could we?

Looking at us, he spoke.

"Figure that one out!" said Grandpa Pangborn. I cut the switch, and the viewer went black.

The way I see it, Pangborn vanished, but not in the right way, so Randall owes me nine dollars. But he says he won the bet, and he won't even give me back the three I handed him before Pangborn got into that fool machine.
