The one on the left-hand door bore the word “In” in big black letters, and the one on the right-hand door flaunted the equally emphatic word “Out.”

“Look!” he exclaimed happily—

Peter’s eyes followed his pointing finger.

“What?”

“Look at the signs. Let’s take ’em.”

“Good idea.”

“Probably pair very rare an’ valuable signs. Probably come in handy.”
