“About half an hour after they had gone, a gondola drew up at Giangolini’s door and a man in a paper mask, wrapped in a black cloak and wearing on his head the inevitable three-cornered hat, got out and went upstairs to the painter’s room. It was empty. The portrait smiled sweetly and a little fatuously from the easel. But no painter stood before it and the model’s throne was untenanted. The long-nosed mask looked about the room with an expressionless curiosity. The wandering glance came to rest at last on the jewel-case that stood where the lovers had carelessly left it, open on the table. Deep-set and darkly shadowed behind the grotesque mask, the eyes dwelt long and fixedly on this object. Long-nosed Pulcinella seemed to be wrapped in meditation. “A few minutes later there was the sound of footsteps on the stairs, of two voices laughing together. The masker turned away to look out of the window. Behind him the door opened noisily; drunk with excitement, with gay, laughable irresponsibility, the lovers burst in. “‘Aha, _caro amico_! Back already. What luck with the diamond?’ “The cloaked figure at the window did not stir; Giangolini rattled gaily on. There had been no trouble whatever about the signatures, no questions asked; he had the passports in his pocket. They could start at once. “Lady Hurtmore suddenly began to laugh uncontrollably; she couldn’t stop. “‘What’s the matter?’ asked Giangolini, laughing too. “‘I was thinking,’ she gasped between the paroxysms of her mirth, ‘I was thinking of old Pantalone sitting at the Misericordia, solemn as an owl, listening’--she almost choked, and the words came out shrill and forced as though she were speaking through tears--‘listening to old Galuppi’s boring old cantatas.’ “The man at the window turned round. ‘Unfortunately, madam,’ he said, ‘the learned maestro was indisposed this morning. There was no concert.’ He took off his mask. ‘And so I took the liberty of returning earlier than usual.’ The long, grey, unsmiling face of Lord Hurtmore confronted them. “The lovers stared at him for a moment speechlessly. Lady Hurtmore put her hand to her heart; it had given a fearful jump, and she felt a horrible sensation in the pit of her stomach. Poor Giangolini had gone as white as his paper mask. Even in these days of _cicisbei_, of official gentlemen friends, there were cases on record of outraged and jealous husbands resorting to homicide. He was unarmed, but goodness only knew what weapons of destruction were concealed under that enigmatic black cloak. But Lord Hurtmore did nothing brutal or undignified. Gravely and calmly, as he did everything, he walked over to the table, picked up the jewel-case, closed it with the greatest care, and saying, ‘My box, I think,’ put it in his pocket and walked out of the room. The lovers were left looking questioningly at one another.” There was a silence. “What happened then?” asked the Lord of the Manor.
