There was a burst of applause when the Prime Minister's dignified and peremptory demand for an explanation eked out about four o'clock in the afternoon--an hour later it was rumoured that the German Ambassador had received his papers. The Stock Exchange remained firm--there was enthusiasm, but no panic. Wolfenden began to wish that he, too, were a soldier, as he passed from one to another of the eager groups of young men about his own age, eagerly discussing the chances of the coming campaign. He walked out into the streets presently, and made his way boldly down to the house which had been pointed out to him as the town abode of Mr. Sabin and his niece. He found it shut up and apparently empty. The servant, who after some time answered his numerous ringings, was, either from design or chance, more than usually stupid. He could not tell where Mr. Sabin was or when he would return--he seemed to have no information whatever as regards the young lady. Wolfenden turned away in despair and walked slowly back towards Pall Mall. At the bottom of Piccadilly he stopped for a moment to let a little stream of carriages pass by; he was about to cross the road when a large barouche, with a pair of restive horses, again blocked the way. Attracted by an unknown coronet upon the panel, and the quiet magnificence of the servants' liveries, he glanced curiously at the occupants as the carriage passed him. It was one of the surprises of his life. The woman nearest to him he knew well by sight; she was the Duchess de Montegarde, one of the richest and most famous of Frenchwomen--a woman often quoted as exactly typical of the old French nobility, and who had furthermore gained for herself a personal reputation for delicate and aristocratic exclusiveness, not altogether shared by her compeers in English society. By her side--in the seat of honour--was Helène, and opposite to them was a young man with a dark, fiercely twisted moustache and distinctly foreign appearance. They passed slowly, and Wolfenden remained upon the edge of the pavement with his eyes fixed upon them. He was conscious at once of something about her which seemed strange to him--some new development. She leaned back in her seat, barely pretending to listen to the young man's conversation, her lips a little curled, her own face the very prototype of aristocratic languor! All the lines of race were in her delicately chiselled features; the mere idea of regarding her as the niece of the unknown Mr. Sabin seemed just then almost ridiculous. The carriage went by without her seeing him--she appeared to have no interest whatever in the passers-by. But Wolfenden remained there without moving until a touch on the arm recalled him to himself. He turned abruptly round, and to his amazement found himself shaking hands vigorously with Densham! "Where on earth did you spring from, old chap?" he asked. "Dick said that you had gone abroad." Densham smiled a little sadly.
