Ruskin took the book and stared curiously at a picture showing a dressed up dog sitting in a chair patting a human on the head. The caption read: MAN'S BEST FRIEND GETS REWARD.
Ruskin glanced back at Bigelow.
"I don't understand," he said slowly. "Is it some kind of joke-book?"
Bigelow grinned narrowly.
"A very bitter joke, Commissioner. A joke of Mother Nature's."
"I'm still not sure I understand...."
"I think you do, Commissioner," Bigelow countered quickly. "Now so many of the things we couldn't understand become clear to us. The naked animal on the floor in the picture is our ancestor, and the hairless thing in the chair is our dog!"
Ruskin shook his head.
"Impossible!"
