"And they didn't see the cars?"
Fenton Hardy shook his head.
"Not the slightest trace of either of them."
Frank and Joe looked at one another blankly.
"Well, if that don't beat the Dutch!" Frank exclaimed.
"You're quite sure of the time?"
"Positive. I had just looked at my watch."
"Well," said Fenton Hardy, "since the cars haven't been seen in any of the other towns and since there aren't any other roads, the Shore Road must hold the solution. I think I'll do a little prospecting around the farms out that way to-morrow."
"We've been doing a little prospecting ourselves," admitted Joe, "but we haven't been very successful so far."
"Keep at it," their father said encouragingly. "And good luck to you both!"
