That Sandford had managed to replace the portfolio in the car and abstract the replica next day was explained, and that he had held the girl completely in his power was equally apparent. Therefore, I have since obtained for her a situation with a well-known firm of photographers in Regent Street, where she still remains. The hump-backed woman and her pseudo-daughter have never been seen since, but only a couple of months ago there was recovered from the Rhine at Coblenz the body of a man whose head was fearfully battered, and whom the police, by his clothes and papers upon him, identified as Charles Sandford, the man with whom I shall ever remember partaking of that peculiarly seductive glass of 1815 cognac. CHAPTER XI THE PERIL OF LONDON Certain information obtained by Ray led us to adopt a novel method of trapping one of the Kaiser's secret agents. About six months after my curious motoring adventure in Essex I sent to the _Berliner Tageblatt_, in Berlin, an advertisement, offering myself as English valet to any German gentleman coming to England, declaring that I had excellent references, and that I, Henry Dickson, had been in service with several English noblemen. The replies forwarded to me caused us considerable excitement. Vera was with us at New Stone Buildings when the postman brought the bulky packet, and we at once proceeded to read them one by one. "Holloa!" she cried, holding up one of the letters. "Here you are, Mr. Jacox! The Baron Heinrich von Ehrenburg has replied!" Eagerly we read the formal letter from the German aristocrat, dated from the Leipziger Strasse, Berlin, stating that, being about to take up his residence in London, he was in want of a good and reliable English servant. He would be at the Ritz Hotel in four days' time, and he made an appointment for me to call. "Good!" cried Ray. "You must ask very little wages. Germans are a stingy lot. The Baron has been acting as a secret agent of the Kaiser in Paris, but had to fly on account of the recent Ullmo affair at Toulon. He's a very clever spy--about as clever, indeed, as Hartmann himself. Why he is coming to England is not quite clear. But we must find out." For the next four days I waited in great anxiety, and when, at the appointed hour, I presented myself at the "Ritz" and was shown into the private salon, the middle-aged, fair-haired, rather elegant man eyed me up and down swiftly as I stood before him with great deference. I was about to play a dangerous game. After a number of questions, and an examination of my credentials, all of which, I may as well admit, had been prepared by Ray and Vera, he engaged me, and that same evening I entered upon my duties, greatly to the satisfaction of Vera and her lover.
