It was getting dark and the headlights cut a brilliant slash through the gloom. Leaving Bayport behind, the boys drove about two miles out until they came to a place where a grassy meadow beside the road provided a favorite parking place for motorists who wished to descend the path leading down through the woods to the beach below.

"This is about as good a place as any," said Frank.

"Suits me."

He drove the car off the road onto the grass. It came to a stop.

"Any one around, Joe?"

Joe looked back.

"No other cars in sight," he reported a moment later.

"Then make it snappy."

Any one observing the roadster at that moment would have seen the two boys clamber out, but in the gloom they would not have seen what followed. For the boys suddenly disappeared.

The roadster remained where it was, parked by the road, in solitary magnificence.
