"But now, tell me all about this friend whom you knew as Sir Digby Kemsley. How did you first become acquainted with him?"
"I met him on a steamer on the Lake of Garda this last summer," was my reply. "I was staying at Riva, the little town at the north end of the lake, over the Austrian frontier, and one day took the steamer down to Gardone, in Italy. We sat next each other at lunch on board, and, owing to a chance conversation, became friends."
"What did he tell you?"
"Well, only that he was travelling for his health. He mentioned that he had been a great deal in South America, and was then over in Europe for a holiday. Indeed, on the first day we met, he did not even mention his name, and I quite forgot to ask for it. In travelling one meets so many people who are only of brief passing interest. It was not until a week later, when I found him staying in the same hotel as myself, the Cavour, in Milan, I learnt from the hall-porter that he was Sir Digby Kemsley, the great engineer. We travelled to Florence together, and stayed at the Baglioni, but one morning when I came down I found a hurried note awaiting me. From the hall-porter I learned that a gentleman had arrived in the middle of the night, and Sir Digby, after an excited controversy, left with him for London. In the note he gave me his address in Harrington Gardens, and asked me not to fail to call on my return to town."
"Curious to have a visitor in the middle of the night," remarked the detective reflectively.
"I thought so at the time, but, knowing him to be a man of wide business interests, concluded that it was someone who had brought him an urgent message," I replied. "Well, the rest is quickly told. On my return home I sought him out, with the result that we became great friends."
"You had no suspicion that he was an impostor?"
"None whatever. He seemed well known in London," I replied. "Besides, if he was not the real Sir Digby, how is it possible that he could have so completely deceived his friends! Why, he has visited the offices of Colliers, the great railway contractors in Westminster—the firm who constructed the railway in Peru. I recollect calling there with him in a taxi one day."
Edwards smiled.
"He probably did that to impress you, sir," he replied. "They may have known him as somebody else. Or he simply went in and made an inquiry. He's evidently a very clever person."
