“No one knew of this except the Queen’s Messenger of whom I spoke. We once left Paris together on the Orient Express. I was going to Constantinople and he was to stop off at Vienna. On the journey I told him of my peculiar way of hiding things and showed him my cigar-case. If I recollect rightly, on that trip it held the grand cross of St. Michael and St. George, which the Queen was sending to our Ambassador. The Messenger was very much entertained at my scheme, and some months later when he met the Princess he told her about it as an amusing story. Of course, he had no idea she was a Russian spy. He didn’t know anything at all about her, except that she was a very attractive woman. It was indiscreet, but he could not possibly have guessed that she could ever make any use of what he told her.
“Later, after the robbery, I remembered that I had informed this young chap of my secret hiding-place, and when I saw him again I questioned him about it. He was greatly distressed, and said he had never seen the importance of the secret. He remembered he had told several people of it, and among others the Princess Zichy. In that way I found out that it was she who had robbed me, and I know that from the moment I left London she was following me, and that she knew then that the diamonds were concealed in my cigar-case.
