Stepping on one side the officer saluted; the car went on.

Until the town was left behind the chauffeur said nothing; but when they began to bowl along the open road beyond he smiled, with much meaning.

"I saw that van he was asking about in the field which you came out of."

"Did you? That shows that you've the faculty of observation--odd how many people are without it."

"And as it was in the same field in which you were you must have seen it too; in fact, you couldn't help it."

"I never said I hadn't."

The chauffeur considered this statement.

"No, I suppose you didn't, if it comes to that--very artful the way you put him off. He thought you said you hadn't seen it."

"Some of those policemen do think at times."

When he had duly pondered this cryptic saying the chauffeur chuckled.
