Madame Bonanni was speaking earnestly to Lushington in an undertone during the interval before the last act, and as he listened to what she said his face became very grave, and his lips set themselves together in a look which his mother knew well enough.
The act proceeded, and Margaret's complete triumph became more and more a matter of certainty. She sang with infinite grace and tenderness that part in the quartet which is intended to express the operatic broken heart, while the Duke, the professional murderer, and Maddalena are laughing and talking inside the inn. That sort of thing does not appeal much to our modern taste, but Margaret did what she could to make it touching, and was rewarded with round upon round of applause.
Lushington rose quietly at this point, slipped on his thin overcoat, took his hat and the big cloak he had bought, nodded to his mother and left the box. A few moments later she rose and followed him.
In due time Margaret reappeared in her man's dress, but almost completely wrapped in the traditional riding mantle. Rigoletto is off when Gilda comes on alone at this point, outside the inn, and the stage gradually darkens while the storm rises. When the trio is over and Gilda enters the ruined inn, the darkness is such, even behind the scenes, that one may easily lose one's way and it is hard to recognise any one.
Margaret disappeared, and hurried off, expecting to meet her maid with the sack ready for the final scene. To her surprise a man was standing waiting for her. She could not see his face at all, but she knew it was Lushington who whispered in her ear as he wrapped her in the big cloak he carried. He spoke fast and decidedly.
'That is why the door at the end of the corridor is open to-night,' he concluded. 'I give you my word that it's true. Now come with me.'
Margaret had told Lushington not very long ago that he always acted like a gentleman and sometimes like a hero, and she had meant it. After all, the opera was over now, and it was only a rehearsal. If there was no sack scene, no one would be surprised, and there was no time to hesitate not an instant.
She slipped her arm through Lushington's, and drawing the hood almost over her eyes with her free hand and the cloak completely round her, she went where he led her. Certainly in all the history of the opera no prima donna ever left the stage and the theatre in such a hurry after her first appearance.
One minute had hardly elapsed in all after she had disappeared into the ruined inn, before she found herself driving at a smart pace in a closed carriage, with Lushington sitting bolt upright beside her like a policeman in charge of his prisoner. It was not yet quite dark when the brougham stopped at the door of Margaret's hotel, and the porter who opened the carriage looked curiously at her riding boot and spurred heel as she got out under the covered way. She and Lushington had not exchanged a word during the short drive.
He went up in the lift with her and saw her to the door of her apartment. Then he stood still, with his hat off, holding out his hand to say good-bye.
