“But we can all come back together. You know where she lives?”

“Oh, yes. Down the river road.”

“We’ll hurry along,” said Billy, “so as to get over to Mayberry’s as early as possible.”

The Speedwells drove away. They went around to several other farmers to pick up the evening’s milk before going home. Then, when their chores were all done and they had supper, Dan and Billy mounted their motorcycles and dashed away through the town and out the river road toward the farmhouse which was the scene of the evening party.

While within the immediate confines of Riverdale they had to run moderately; but it was already after half-past eight, they wanted to reach Mayberry’s before the fun was all over, and therefore “let out” the motors when they got upon the river road.

The white highway before them was deserted clear down to the bend at which Dan Speedwell had first seen the maroon car of the bank robbers on Saturday afternoon. That trio of criminals had gotten away: all pursuit had been futile.

But as the two boys shot around the bend they sighted an automobile chugging slowly toward them. It was not far beyond where the shadowy outline of their rudely constructed derrick was visible.

An automobile on this road was no uncommon sight; but the attention of Dan and Billy was called particularly to it because it showed no lights!

The boys flashed past the slowly moving machine at racing pace; yet Billy gained some particular knowledge of the car and its single occupant.

“Hey, Dannie!” he shouted. “Did you see him?”
