Densham drew a square card from his pocket, and held it out under the gas-light. From it, it appeared that the Princess Lobenski desired the honour of his company at any time that evening between twelve and two. "A card for to-night, by Jove!" Harcutt exclaimed. Densham nodded, and replaced it in his pocket. "You see, Harcutt," he said, "I am bound to take an advantage over you! I only got this card by an accident, and I certainly do not know the Princess well enough to present you. I shall be compelled to leave you here! All that I can promise is, that if I discover anything interesting I will let you know about it to-morrow. Good-night!" Harcutt watched him disappear through the open doors, and then walked a little way along the pavement, swearing softly to himself. His first idea was to wait about until they came out, and then follow them again. By that means he would at least be sure of their address. He would have gained something for his time and trouble. He lit a cigarette, and walked slowly to the corner of the street. Then he turned back and retraced his steps. As he neared the crimson strip of drugget, one of the servants drew respectfully aside, as though expecting him to enter. The man's action was like an inspiration to him. He glanced down the vista of covered roof. A crowd of people were making their way up the broad staircase, and amongst them Densham. After all, why not? He laughed softly to himself and hesitated no longer. He threw away his cigarette and walked boldly in. He was doing a thing for which he well knew that he deserved to be kicked. At the same time, he had made up his mind to go through with it, and he was not the man to fail through nervousness or want of _savoir faire_. At the cloak-room the multitude of men inspired him with new confidence. There were some, a very fair sprinkling, whom he knew, and who greeted him indifferently, without appearing in any way to regard his presence as a thing out of the common. He walked up the staircase, one of a little group; but as they passed through the ante-room to where in the distance Prince and Princess Lobenski were standing to receive their guests, Harcutt adroitly disengaged himself--he affected to pause for a moment or two to speak to an acquaintance. When he was left alone, he turned sharp to the right and entered the main dancing-salon. He was quite safe now, and his spirits began to rise. Yonder was Densham, looking very bored, dancing with a girl in yellow. So far at least he had gained no advantage. He looked everywhere in vain, however, for a man with a club foot and the girl in white and diamonds. They must be in one of the inner rooms. He began to make a little tour.
