I wish you would follow up that path in the opposite direction for a bit, while I poke about here. If you find the marks of a bicycle wheel, don’t touch ’em, but come back and tell me.”

Harold followed the path for half a mile or so in the direction of the Studland road, and returned shaking his head. Hanslet had by this time finished his inspection of the ruins. He turned to the Professor, who had joined him. “Well, there’s nothing very definite to be seen here,” he said, with his usual cheerful smile. “What do you suggest we do next, Professor?”

“Return to the inn for dinner,” replied Dr. Priestley. “Tomorrow, if you agree, I propose to return to London by an early train.”
