She stopped. He at once stopped, too, keeping two hundred yards behind her. Her next movement was as unexpected as it was spirited. She suddenly whisked her wheels round and dashed straight at him. He was as quick as she, however, and darted off in desperate flight. Presently she came back up the road again, her head haughtily in the air, not deigning to take any further notice of her silent attendant. He had turned also, and still kept his distance until the curve of the road hid them from my sight.

I remained in my hiding-place, and it was well that I did so, for presently the man reappeared, cycling slowly back. He turned in at the Hall gates, and dismounted from his machine. For some minutes I could see him standing among the trees. His hands were raised, and he seemed to be settling his necktie. Then he mounted his cycle and rode away from me down the drive towards the Hall. I ran across the heath and peered through the trees. Far away I could catch glimpses of the old gray building with its bristling Tudor chimneys, but the drive ran through a dense shrubbery, and I saw no more of my man.

However, it seemed to me that I had done a fairly good morning's work, and I walked back in high spirits to Farnham. The local house agent could tell me nothing about Charlington Hall, and referred me to a well known firm in Pall Mall. There I halted on my way home, and met with courtesy from the representative. No, I could not have Charlington Hall for the summer. I was just too late. It had been let about a month ago. Mr. Williamson was the name of the tenant. He was a respectable, elderly gentleman. The polite agent was afraid he could say no more, as the affairs of his clients were not matters which he could discuss.

Mr. Sherlock Holmes listened with attention to the long report which I was able to present to him that evening, but it did not elicit that word of curt praise which I had hoped for and should have valued. On the contrary, his austere face was even more severe than usual as he commented upon the things that I had done and the things that I had not.

“Your hiding-place, my dear Watson, was very faulty. You should have been behind the hedge, then you would have had a close view of this interesting person. As it is, you were some hundreds of yards away and can tell me even less than Miss Smith.
