No one had noticed. Dan first had observed the car at the intersection.
“Note down the license number if you can,” the Cub leader instructed. “The car probably isn’t following us—but it’s just as well to have the license number.”
The three boys peered intently through the rear window. The license plate number could not be easily distinguished.
“It’s too misty outside,” Dan complained.
“He’s dropping farther back too,” Fred observed. “Must have caught on that we’re watching him.”
“I got the first two letters and number,” Brad said, jotting it down on a scrap of paper. “FJ-3. I couldn’t make out the last number too well. I think it was 2, though.”
The following automobile now had dropped a considerable distance behind.
“It may have been our imagination,” Mr. Hatfield said in relief. “Finding that box of money and having it in our possession, has given us all a case of the jitters.”
At the next corner, the Cub leader swung back onto the main, well-traveled street. The other car had disappeared from view.
“I guess I was wrong,” Dan admitted. “Either that, or the fellow became suspicious that we were watching.”
