The pause indicated Joey was expected to react. "Formula #53?"
Ewing moved back to the light. "My fifty-third experiment. Radical departure from commercial developers."
"It succeeded?"
"It succeeded, Mr. Barrett, but not in the way I had imagined." The fish-white hands rested on the photo album. "I developed some film in Formula #53 and received the shock of my life." His voice was a whisper. "The pictures on the negative were NOT the pictures I had taken."
He paused to watch the effect on Barrett. Joey scratched his ear. "You took one set of pictures and the negatives you got were of another set?"
"I know what you're thinking," Ewing said. "What I thought at first: that I'd gotten hold of the wrong film. But that wasn't the answer. The same thing happened again and again. Whenever I used Formula #53 as my developer, I produced a strange set of pictures."
Joey stood up nervously. The old boy was crazier than he had first guessed. Humoring him seemed the only answer. "That's incredible."
Ewing nodded excitedly. "I thought I was losing my mind. But, slowly, I began to realize what had happened."
"What?"
The old man sank into the chair by the table. "School of modern philosophers ... teaches all time is co-existent."
