The more he considered the matter the more convinced he became that he was right, and the conviction was on the whole a relief. He had been uneasy for some time, and Ghisleri's guarded words had not satisfied him; chance, however, had done what Ghisleri would not do, and the mystery was solved. The Princess of Gerano was at home that evening, and Arden of course went to the palace early, and was the last to leave.
Three times between half-past ten and half-past two o'clock Laura and he installed themselves side by side at some distance from the drawing-room, and each time their conversation lasted over half an hour. It was not a set ball, but one of the regular weekly informal dances of which there are so many in Rome during the season. The first interruption of Arden's talk appeared in the shape of Don Francesco Savelli, who asked Laura for a turn. Oddly enough she glanced at Lord Herbert's face before accepting, and the action sent a strange thrill to his heart. He struggled to his feet as she rose to go away with Savelli, and then sank back again and remained some time where he was, absently watching the people who passed. His face was very pale and weary now that the excitement of conversation had subsided, and he felt that if he was not positively ill, he was losing the little strength he had with every day that passed. Late hours, heated rooms, and strong emotions were not the best tonics for his feeble physical organisation, and he knew it. At last he made an effort, got up, and moved about in the crowd, exchanging a few words now and then with a passing acquaintance, but too preoccupied and perhaps too tired to talk long with indifferent people. He nodded as Ghisleri passed him with the Contessa dell' Armi on his arm, and he thought there was a bad light in his friend's eyes, though Pietro was looking better than in the afternoon. The two had evidently been dancing together, for the Contessa's white neck heaved a little, as though she were still out of breath. She was a short, slight woman of exquisite figure, very fair, with deep violet eyes and small classic features, almost hard in their regularity; evidently wilful and dominant in character. Arden watched the pair as they went on in search of a vacant sofa just big enough for two.
They had scarcely sat down and he could see that Ghisleri was beginning to talk, when Anastase Gouache appeared and stood still before them. To Arden's surprise the Contessa welcomed him with a bright smile and pointed to a chair at her side of the sofa. Anastase Gouache was a celebrated painter who had married a Roman lady of high birth, and was a very agreeable man, but Arden had not expected that he would be invited so readily to interrupt so promising a conversation. Ghisleri's face expressed nothing. He appeared to join in the talk for a few minutes and then rose and left the Contessa with Gouache. She looked after him, and Arden thought she grew a shade paler and frowned. A faint smile appeared on the Englishman's face and was gone again in an instant as Ghisleri came near him, returning again to the ball-room. Ghisleri had glanced at him as he passed and had seen that he was not talking to a lady.
"May I have the next dance, Miss Carlyon?" asked Pietro, when he found Laura in a corner with Francesco Savelli. "Thanks," he said, as she nodded graciously, and he passed on.
"Will you give me the dance after the next?" he inquired a few minutes later, coming up with Donna Adele, who was moving away on young Frangipani's arm.
"Certainly, caro Ghisleri," she answered, with alacrity, "as many as you please."
"You are very good," he said, with a slight bow, and withdrew to a window near Laura to wait until the waltz began. He could see Arden through the open door from the place where he stood.
When the dance was over he led Laura out and took one turn through the rooms, making a few commonplace remarks on the way. Coming back, he stopped as though by accident close to Lord Herbert.
"I am afraid you will think me very rude if I ask you to let me leave you," he said. "I am engaged for the next dance—it is a quadrille—and I must find a vis-à-vis."
Arden of course heard and presented himself immediately in Ghisleri's place. Laura was quite ready to go back with him to the sofa in the corner, and they resumed their conversation almost at the point at which it had been interrupted by Francesco Savelli. Neither of them ever knew that Ghisleri had brought them together again by a little social skill, just beyond what most people possess. Arden looked after him, half believing that he had only given Laura an excuse for leaving her in order to return to the Contessa dell' Armi, who was now surrounded by half a dozen men, beginning with old Spicca, who, as has been said, was still alive in those days, and ending with the little Vicomte de Bompierre, a young French attaché with a pleasant voice, a bright smile, and an incipient black moustache. But to Arden's surprise Ghisleri took quite a different direction, and began to speak to one man after another, evidently trying to secure a vis-à-vis for the square dance.
