He went into a well-known dining establishment and had some dinner, and--an unusual thing with him--drank a pint of wine. He had learned of the waiter what time the Opera commenced; and as soon as the clock-hands reached half-past seven he hurried off and presented himself at the pit entrance, where, on account of his morning costume, he was refused admittance. He was told, however, that there would be no obstacle to his admission into the amphitheatre; and he accordingly climbed into that wild region, and there secured a front seat. He had hired a glass from the check-taker, and with it he now proceeded to scan the house, as yet cold and nearly, empty. Miss Guyon was not there. The opera commenced, and still she did not arrive. Streightley, plying his glass at two minutes' intervals, at length saw her advance to the front of a box on the first tier and take the seat with her back to the stage. With her was the lady whom he had seen in the carriage at the door in Queen Anne Street; and they had scarcely been seated ten minutes before they were joined by the young man who had been of Miss Guyon's party in the Park. Streightley recognised him in an instant, and hated him for his easy manners and his good looks; for he was a good-looking young fellow of six-and-twenty, with fair hair parted in the middle, regular features, and brilliant teeth. Other men visited the box during the evening, but this young fellow only went away once, and then Streightley saw him in the stalls with his glass rivetted on Miss Guyon, who, as he also remarked, attracted a great deal of attention. Then he returned to the box and remained there during the rest of the evening, until nearly the close of the opera, indeed, when Streightley saw the party preparing to move. Robert instantly seized his hat, and rushing downstairs arrived at the door in time to hear loud shouts of "Lady Henmarsh's carriage stops the way!" and to see the visitor of the morning on the arm of an old gentleman, and Miss Guyon closely escorted by the fair-haired equestrian. As she stepped into the carriage Miss Guyon looked up at her attendant cavalier with a smile that Robert Streightley would at that instant have sacrificed all his wealth to have had directed at him. He was mad with rage and jealousy, and could have struck down the simpering fool, who muttered something inaudible under his breath, and raised his hat as the carriage drove off. What had he said in return for that look? That Robert Streightley could never know. Who was he who created the first pang of jealousy that had ever rankled in Streightley's heart? That he would learn at once; he would follow the man, and see where he lived, and learn who he was.
