That day I lunched and dined in my private sitting-room, in order to avoid the pair, and continue my observations. That night I caught sight of Elise, whose exquisite gown of pale pink chiffon was creating a sensation among the well-dressed women, for the news of her engagement to the young millionaire banker made her the most-talked-of and admired girl in the great crowded hotel.

At eleven that night, when I believed that the ladies had gone to bed, I ventured downstairs to the fumoir. As I went along the corridor, I noticed Madame’s English friend, with his overcoat over his evening clothes, leaving the hotel for a stroll, while almost at the same moment Madame herself emerged from one of the rooms, and, without doubt, recognised me, I saw her start quickly, hesitate for a second, and then turn away in pretence that she had not noticed me.

Her attitude was distinctly curious, and therefore I made no attempt to claim acquaintance.

The mystery of the situation was, however, considerably increased when, next morning, I was surprised to learn that the Countess Gemsenberg had received bad news from Munich, that her husband had been injured in a lift accident, and that she and her daughter had left Mattuglie—the station for Abbazia, three miles distant—by the 8:48 train, young Hausner leaving by the same train.

From the servants I discovered that Madame and her daughter had spent half the night packing, and had not announced their departure until six that morning. No telegram had been received by either of the trio, which seemed to me a curiously interesting point.

Was it possible that Madame had fled upon recognising me? If so, for what reason?

The mystery surrounding the pair attracted me, and during the further fortnight I remained at the Stefanie, I made inquiries concerning them. It appeared that a few days after their arrival the Countess herself had told two German ladies of her daughter’s engagement to young Hausner, and that the latter would arrive in a few days. This news at once spread over the big hotel, and when the young man arrived he at once became the most popular person in Abbazia.

The Countess’s enemies, however, declared that one night in the hotel-garden she and Hausner had a violent quarrel, but its nature was unknown, because they spoke in English. Mademoiselle was also present, and instead of supporting her lover, took her mother’s side and openly abused him.

And yet next morning the pair were walking arm-in-arm beside the sea, as though no difference of opinion had occurred.

As for the Englishman in brown, I ascertained that he did not live there, but at the Quarnero, down by the sea. Those who heard him talk declared that the Countess addressed him as Mr Wilkinson, and that he was undoubtedly English.
