Our friend, Sir Henry, and the lady had halted on the path and were standing deeply absorbed in their conversation, when I was suddenly aware that I was not the only witness of their interview. A wisp of green floating in the air caught my eye, and another glance showed me that it was carried on a stick by a man who was moving among the broken ground. It was Stapleton with his butterfly-net. He was very much closer to the pair than I was, and he appeared to be moving in their direction. At this instant Sir Henry suddenly drew Miss Stapleton to his side. His arm was round her, but it seemed to me that she was straining away from him with her face averted. He stooped his head to hers, and she raised one hand as if in protest. Next moment I saw them spring apart and turn hurriedly round. Stapleton was the cause of the interruption. He was running wildly towards them, his absurd net dangling behind him. He gesticulated and almost danced with excitement in front of the lovers. What the scene meant I could not imagine, but it seemed to me that Stapleton was abusing Sir Henry, who offered explanations, which became more angry as the other refused to accept them. The lady stood by in haughty silence. Finally Stapleton turned upon his heel and beckoned in a peremptory way to his sister, who, after an irresolute glance at Sir Henry, walked off by the side of her brother. The naturalist’s angry gestures showed that the lady was included in his displeasure. The baronet stood for a minute looking after them, and then he walked slowly back the way that he had come, his head hanging, the very picture of dejection.

What all this meant I could not imagine, but I was deeply ashamed to have witnessed so intimate a scene without my friend’s knowledge. I ran down the hill therefore and met the baronet at the bottom. His face was flushed with anger and his brows were wrinkled, like one who is at his wit’s ends what to do.

“Halloa, Watson! Where have you dropped from?” said he. “You don’t mean to say that you came after me in spite of all?”

I explained everything to him: how I had found it impossible to remain behind, how I had followed him, and how I had witnessed all that had occurred. For an instant his eyes blazed at me, but my frankness disarmed his anger, and he broke at last into a rather rueful laugh.

“You would have thought the middle of that prairie a fairly safe place for a man to be private,” said he, “but, by thunder, the whole countryside seems to have been out to see me do my wooing—and a mighty poor wooing at that! Where had you engaged a seat?”

“I was on that hill.”

“Quite in the back row, eh? But her brother was well up to the front. Did you see him come out on us?”

“Yes, I did.”

“Did he ever strike you as being crazy—this brother of hers?”
