From inquiries I made later on I found that the concert singer had suddenly left the hotel, therefore I went over to Beaulieu and had an instructive chat with the hall porter, a German of course. From him I learnt that the Signorina had been staying there ever since the date when we had arrived at Nice, and, further, that two gentleman had been frequently in the habit of calling upon her. One was a smart young Frenchman who came in a motor-car, and the other was a German. From the description of the latter I at once came to the conclusion that it was none other than Herr Schäfer! "The one gentleman did not know of the other's visits," said the bearded porter, with a laugh. "The Signorina always impressed silence upon me, because she thought one would be jealous of the other. The German gentleman seemed very deeply in love with her, and she called him Hans. He accompanied her when she left here for San Remo." I reported this to His Highness, but he made no remark. That some devilish plot was being carried out I suspected. The Hohenzollerns are ready to go to any length to prevent their black secrets from leaking out. My surmise proved correct, for, a week later, some fishermen found upon the brown rocks near Capo Verde, beyond San Remo, the body of a woman, fully dressed, afterwards identified as that of Irene Speroni, the singer so popular in Rome. It was proved that on the previous night she had been seen by two peasants walking along the sea road near San Lorenzo, accompanied by a tall, thin man, who seemed greatly excited, and was talking in German. It was believed by the Italian police that the unknown German, in a fit of jealousy, threw her into the sea. From facts I gathered some months later I realized that the whole plot had been most cunningly conceived by the Crown-Prince. Schäfer, after his return from America, had met the woman Speroni, who was performing in London, and she had, unknown to him, opened his dispatch-box, and from some secret correspondence had learned the real truth regarding the proposed _entente_ which the Emperor contemplated. Schäfer, alarmed at the woman's knowledge, and yet fascinated by her charms, had gone to the Crown-Prince, and he, in turn, had seen the woman in Wiesbaden. Finding her so dangerous to the Emperor's plans, His Highness then conceived a fiendish plot. He first introduced her to a young French Marquis, de Vienne by name, who pestered her with his attentions, and followed her to Beaulieu. Having so far succeeded, the Crown-Prince went to Nice, and cleverly played upon Schäfer's love for the woman, pointing out that she was playing a double game, and urging him to watch. He did so, and discovered the truth. Then there occurred the tragedy of jealousy, exactly as the police believed. Herr Schäfer, the tool of His Imperial Highness, had, however, escaped to Germany, and the police of San Remo are still in ignorance of his identity. SECRET NUMBER SIX
