"Does she know about the Austrian episode?"
"The cunning devil has told her every unsavoury public scandal of his past life, but always in such a way as to make himself out to be an innocent martyr. She absolutely accepts his version and will listen to no other."
"Dear me! But surely you have inadvertently let out the name of your client? It is no doubt General de Merville."
Our visitor fidgeted in his chair.
"I could deceive you by saying so, Mr. Holmes, but it would not be true. De Merville is a broken man. The strong soldier has been utterly demoralized by this incident. He has lost the nerve which never failed him on the battlefield and has become a weak, doddering old man, utterly incapable of contending with a brilliant, forceful rascal like this Austrian. My client, however, is an old friend, one who has known the General intimately for many years and taken a paternal interest in this young girl since she wore short frocks. He cannot see this tragedy consummated without some attempt to stop it. There is nothing in which Scotland Yard can act. It was his own suggestion that you should be called in, but it was, as I have said, on the express stipulation that he should not be personally involved in the matter. I have no doubt, Mr. Holmes, with your great powers you could easily trace my client back through me, but I must ask you, as a point of honour, to refrain from doing so, and not to break in upon his incognito."
Holmes gave a whimsical smile.
"I think I may safely promise that," said he. "I may add that your problem interests me, and that I shall be prepared to look into it. How shall I keep in touch with you?"
"The Carlton Club will find me. But, in case of emergency, there is a private telephone call, 'XX.31.'"
Holmes noted it down and sat, still smiling, with the open memorandum-book upon his knee.
"The Baron's present address, please?"
