As these thoughts were passing through my mind I distinctly heard some one step into the verandah from the door on my right, and a moment later, to my surprise, the stout old gentleman who, half an hour or so before, I had thought so typical of an English merchant, came round the chairs towards me. Having reached the place where I was sitting he stopped, and, taking a cheroot from his pocket, proceeded to light it. During the operation I noticed that he took careful stock of me, and, when he had finished, said quietly,—

"Mr. Collon, I believe?"

"That is my name," I answered, looking up at him through the cloud of smoke. "Pray how do you come to be acquainted with it?"

"I have heard of you repeatedly," he replied.

"Indeed," I said. "And pray is there any way in which I can be of service to you?"

"I think so," he replied, with a smile. "As a matter of fact, I have just arrived from Madras, where, hearing in an indirect way that you were supposed to be in Ceylon, I undertook this journey on purpose to see you."

"Indeed!" I answered, with considerable surprise. "And pray what is it you desire me to do for you?"

"I want you to take charge of what I think promises to be one of the most extraordinary and complicated cases even in your extensive repertoire," he said.

"If it is as you say, it must indeed be a singular one," I answered. "Perhaps it would not give you too much trouble to furnish me with the details."

"I will do so with the greatest pleasure," he replied. "If you will permit me to take my seat beside you, you shall hear the story from beginning to end. I think, then, that you will agree with me that, provided you undertake it, it will, as I insinuated just now, in all probability prove the most sensational, as well as the most lucrative, case in which even you have hitherto been engaged."
