"No, my dear fellow, YOU will go down. This may be some trifling intrigue, and I cannot break my other important research for the sake of it. On Monday you will arrive early at Farnham; you will conceal yourself near Charlington Heath; you will observe these facts for yourself, and act as your own judgment advises. Then, having inquired as to the occupants of the Hall, you will come back to me and report. And now, Watson, not another word of the matter until we have a few solid stepping-stones on which we may hope to get across to our solution."
We had ascertained from the lady that she went down upon the Monday by the train which leaves Waterloo at 9.50, so I started early and caught the 9.13. At Farnham Station I had no difficulty in being directed to Charlington Heath. It was impossible to mistake the scene of the young lady's adventure, for the road runs between the open heath on one side and an old yew hedge upon the other, surrounding a park which is studded with magnificent trees. There was a main gateway of lichen-studded stone, each side pillar surmounted by mouldering heraldic emblems; but besides this central carriage drive I observed several points where there were gaps in the hedge and paths leading through them. The house was invisible from the road, but the surroundings all spoke of gloom and decay.
The heath was covered with golden patches of flowering gorse, gleaming magnificently in the light of the bright spring sunshine. Behind one of these clumps I took up my position, so as to command both the gateway of the Hall and a long stretch of the road upon either side. It had been deserted when I left it, but now I saw a cyclist riding down it from the opposite direction to that in which I had come. He was clad in a dark suit, and I saw that he had a black beard. On reaching the end of the Charlington grounds he sprang from his machine and led it through a gap in the hedge, disappearing from my view.
A quarter of an hour passed and then a second cyclist appeared. This time it was the young lady coming from the station. I saw her look about her as she came to the Charlington hedge. An instant later the man emerged from his hiding-place, sprang upon his cycle, and followed her. In all the broad landscape those were the only moving figures, the graceful girl sitting very straight upon her machine, and the man behind her bending low over his handle-bar, with a curiously furtive suggestion in every movement. She looked back at him and slowed her pace. He slowed also. 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 few 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 grey building with its bristling Tudor chimneys, but the drive ran through a dense shrubbery, and I saw no more of my man.
