After refreshments were served Sohlberg played. Cowperwood was interested by his standing figure—his eyes, his hair—but he was much more interested in Mrs. Sohlberg, to whom his look constantly strayed. He watched her hands on the keys, her fingers, the dimples at her elbows. What an adorable mouth, he thought, and what light, fluffy hair! But, more than that, there was a mood that invested it all—a bit of tinted color of the mind that reached him and made him sympathetic and even passionate toward her. She was the kind of woman he would like. She was somewhat like Aileen when she was six years younger (Aileen was now thirty-three, and Mrs. Sohlberg twenty-seven), only Aileen had always been more robust, more vigorous, less nebulous. Mrs. Sohlberg (he finally thought it out for himself) was like the rich tinted interior of a South Sea oyster-shell—warm, colorful, delicate. But there was something firm there, too. Nowhere in society had he seen any one like her. She was rapt, sensuous, beautiful. He kept his eyes on her until finally she became aware that he was gazing at her, and then she looked back at him in an arch, smiling way, fixing her mouth in a potent line. Cowperwood was captivated. Was she vulnerable? was his one thought. Did that faint smile mean anything more than mere social complaisance? Probably not, but could not a temperament so rich and full be awakened to feeling by his own? When she was through playing he took occasion to say: “Wouldn’t you like to stroll into the gallery? Are you fond of pictures?” He gave her his arm. “Now, you know,” said Mrs. Sohlberg, quaintly—very captivatingly, he thought, because she was so pretty—“at one time I thought I was going to be a great artist. Isn’t that funny! I sent my father one of my drawings inscribed ‘to whom I owe it all.’ You would have to see the drawing to see how funny that is.” She laughed softly. Cowperwood responded with a refreshed interest in life. Her laugh was as grateful to him as a summer wind. “See,” he said, gently, as they entered the room aglow with the soft light produced by guttered jets, “here is a Luini bought last winter.” It was “The Mystic Marriage of St. Catharine.” He paused while she surveyed the rapt expression of the attenuated saint. “And here,” he went on, “is my greatest find so far.” They were before the crafty countenance of Caesar Borgia painted by Pinturrichio. “What a strange face!” commented Mrs. Sohlberg, naively. “I didn’t know any one had ever painted him. He looks somewhat like an artist himself, doesn’t he?” She had never read the involved and quite Satanic history of this man, and only knew the rumor of his crimes and machinations. “He was, in his way,” smiled Cowperwood, who had had an outline of his life, and that of his father, Pope Alexander VI., furnished him at the time of the purchase. Only so recently had his interest in Caesar Borgia begun. Mrs. Sohlberg scarcely gathered the sly humor of it.
