Miss Stapleton was a very attractive woman. She was slim and tall, with beautiful dark eyes. I thought she looked very different from her brother. She had dark hair, but her brother had fair hair. They were both about thirty years old. Stapleton looked a little older. He was a small, thin, clean-shaven man, with a long face. “How do you do, Miss Stapleton,” I said. “Your brother has told me about the Great Grimpen Mire and the unusual flowers and birds. Did you hear that strange sound a moment ago? Does the wind often make this sound?”
