While he was engaged in this task, a carriage drove up out of the dark, as it were, and halted beside the other one. A cold sweat broke out over the young man as he observed its arrival. This devil of a Zouroff had been too quick for him. Then his countenance cleared as he recognised the first man who stepped out. It was the leader of his faithful bodyguard. He had, in the excitement of passing events, forgotten them. "You have lost sight of us, Signor, but, you see, we have not lost sight of you," said the chief of the party. "We followed you to that mean street where your friend lodged, we saw you come out transformed in appearance, we followed you to the villa of Madame Quéro, we drove behind you and Prince Zouroff to the Palace, we saw what happened there, and we came after you at lightning speed. Now, how can we help you? There is some strange work going on, that is easy to see. This is the house of Count Golitzine, you want to see him. But I expect they are all gone to bed." "Yes, my friend, so much has happened in the last hour or two that I had forgotten you," was Corsini's answer. "Tell one of the men to knock at the door till it is opened. If the Count has gone to bed, he must get up. And you and the others guard that carriage and look out for Prince Zouroff." The house seemed wrapped in darkness, and in fact everybody had retired to rest except the energetic Count himself. Five nights out of six he worked into the morning hours. To-night he had a special reason for sitting up late. At any moment he might expect a visit from the young Italian, to report the results of the meeting at the Villa Quéro. He peered into the darkness and his astonished gaze rested on more than he expected to see. He was prepared to see Corsini, to observe the bodyguard lurking in the background; but the carriage and two impatient horses champing at their bits was more than he had bargained for. "In Heaven's name, what is this, Corsini?" Nello advanced and whispered in his ear. "I dare say these men suspect as much as I know, but for the present we need not assume it. Inside that carriage are two helpless women, drugged by that ruffian Zouroff, the Princess Nada and her maid. I will tell you all the details of the adventure later. Enough to say that I have been able to rescue them from his clutches and drive them to your house. You will not refuse them shelter?" "Of course not," replied the Count at once. "Bring them in and I will at once arouse the Countess. Drugged, you say! Send round one of the fellows for the nearest doctor: he is the same man who succoured you at Pavlovsk. Stay, I will give the address myself." The two helpless forms were carried in. The Countess Golitzine was aroused. The doctor arrived. It was some time before he could bring them round. Zouroff and his satellites were evidently acquainted with the secret of a very powerful narcotic. He came down at length to the Count in his study, where he found Corsini.
