Moser knew nothing of any valuable jewellery, but it had been remarked by the servants that the heavy trunk in the lady's bedroom was always scrupulously locked. Marie Devine, the maid, was as popular as her mistress. She was actually engaged to one of the head waiters in the hotel, and there was no difficulty in getting her address. It was 11 Rue de Trajan, Montpellier. All this I jotted down and felt that Holmes himself could not have been more adroit in collecting his facts.

Only one corner still remained in the shadow. No light which I possessed could clear up the cause for the lady's sudden departure. She was very happy at Lausanne. There was every reason to believe that she intended to remain for the season in her luxurious rooms overlooking the lake. And yet she had left at a single day's notice, which involved her in the useless payment of a week's rent. Only Jules Vibart, the lover of the maid, had any suggestion to offer. He connected the sudden departure with the visit to the hotel a day or two before of a tall, dark, bearded man. “Un sauvage—un véritable sauvage!” cried Jules Vibart. The man had rooms somewhere in the town. He had been seen talking earnestly to Madame on the promenade by the lake. Then he had called. She had refused to see him. He was English, but of his name there was no record. Madame had left the place immediately afterwards. Jules Vibart, and, what was of more importance, Jules Vibart's sweetheart, thought that this call and the departure were cause and effect. Only one thing Jules would not discuss. That was the reason why Marie had left her mistress. Of that he could or would say nothing. If I wished to know, I must go to Montpellier and ask her.

So ended the first chapter of my inquiry. The second was devoted to the place which Lady Frances Carfax had sought when she left Lausanne. Concerning this there had been some secrecy, which confirmed the idea that she had gone with the intention of throwing someone off her track. Otherwise why should not her luggage have been openly labelled for Baden? Both she and it reached the Rhenish spa by some circuitous route. This much I gathered from the manager of Cook's local office. So to Baden I went, after dispatching to Holmes an account of all my proceedings and receiving in reply a telegram of half-humorous commendation.

At Baden the track was not difficult to follow. Lady Frances had stayed at the Englischer Hof for a fortnight. While there she had made the acquaintance of a Dr.
