Wilson went out and walked around the block. He had told a deliberate lie and was perpetrating a downright fraud, but he felt no conscientious scruples over it. It was only after he had exhausted every legitimate method that he had resorted to this. When he 109 came around to the entrance door again he found a young man standing there with a tool bag in his hand. He stepped up to him.
“This Mr. Riley?”
“Yes, sir.”
“I was to tell you to go on right out to the house. The man is there.”
“All right, sir.”
Wilson started on, but stopped to look into the drugstore window. The man went down the street to the car corner. Wilson again circled the block and waited until he saw Riley board the car on the front platform. He kept out of sight until the car had almost passed him and then swung on to the rear. The stratagem was simplicity itself.
At the end of a ten-minute ride the inspector swung off and at the next corner Wilson followed. It was easy enough to keep the man in sight, and apparently he himself had escaped detection. The inspector approached a modest looking house setting a bit back from the road and, going to the front door, rang the bell. At the end of perhaps three minutes he rang again. At the end of another five he rang a third time. The curtains were down in the front windows, but that was not uncommon in hot June days. The inspector went to the rear. In a few minutes he came back. He tried the door once more and then, apparently bewildered, came out. He hung around for some ten minutes more, and then, returning to the corner, took the first car back.
It seemed clear enough that the occupants of the house were gone, but Wilson waited a few minutes longer, unwilling to accept the possibilities this suggested. He even went up and tried the bell himself. A servant from the neighboring house called across to him:
“They all drove off in a carriage an hour ago, sir,” she said.
