She was too proud to go after them, but her fingers curved round the window-seat in the effort to restrain herself, and her spirits plunged into an abyss of dull despair, emerging only on jealous and torturing wings to drop again. She realized the mistake she had made in the exuberance of her happy self-confidence; for a girl like Miss Holmes can make heavy running in an hour. On the steamer and in the various pensions where the Moultons had lingered she had often seen what no doubt was this same type of girl retire into a corner with the man she had marked for her own and talk—or listen—hour after hour; and Catalina had speculated upon their subjects, wondering that one human being could interest another for so long a time without the exterior aids of travel. The man had always looked as engrossed as the girl, and Catalina was forced to conclude that the mysterious arts were effective, and wished it were not forbidden to listen behind a curtain, but only that curiosity might be satisfied—she scorned arts herself. Now she wondered distractedly what this ashen-haired houri was talking about to make Over forget his very manners; but none of the long, desultory conversations, followed by the longer silences peculiar to her experience with him, threw light on the weapons of this accomplished ruler of hearts; although the bare idea that they might be leaning over the parapet side by side in a familiar silence brought Catalina to her feet and turned her sharply towards the arcade. But at that moment she saw them coming. Over was a little ahead of his companion, who was smiling with her lips, and he came forward with some anxiety in his eyes. “I only just missed you,” he said. “I thought you were there in the room lost in one of your silent moods. When did you come down?” “Only a little while ago,” said Catalina, sweetly, and she saw the eyes of the other girl flash with something like fear. She also noted that her cheeks were flushed. “You have got a little sunburned,” she said, with concern for a fine complexion in her voice. “It is much cooler down here. Have we time to go into the Sala de los Embajadores?” And Over was made subtly aware of the second-rate quality of Miss Holmes’s accent.
