The Landhofmeisterin was easily recognisable from her great height. For a moment she had contemplated dressing in man's clothes, but Serenissimus had dissuaded her. The Duke's domino was of 'Grävenitz yellow' of the same hue as that of the Landhofmeisterin. Madame de Ruth had refused to go masked.

'My old face is mask enough,' she said; and Zollern, delighted to escape the ordeal of a travesty, had declared he would keep his old friend company. So the two sat together and made merry over the grotesque appearance of the other guests.

At first, many had approached the undominoed couple and, under cover of carnival licence, some had ventured to say sharp things to the old courtesan, but each in turn retired discomfited before the sting of Madame de Ruth's quick wit. The Landhofmeisterin stood near to her friend. She felt strangely lonely in this disguised crowd, and Serenissimus held aloof from her. She saw him exchanging compliments with a light blue domino, from whose supple movements Wilhelmine guessed to be a young and graceful woman.

A sudden wave of jealous fear invaded the Landhofmeisterin's heart. And leaving her safe place behind Madame de Ruth and Zollern, she walked out into the crowd of revellers. Instantly several masks left the dancing, laughing, whirling main stream and approached the newcomer. 'Fair mask, come tread a measure!' 'Do you seek love or amusement here?' and many other meaningless absurdities were squeaked into her ear by some unwary ones who had not recognised the much-feared Landhofmeisterin in the tall yellow-clad figure. She shot a glance of contempt at her interlocutors and pushed past them. Of a sudden she was surrounded by a circle of red-garbed gnomes who danced round her. 'Let me pass, good people,' she said; and when they would not, she broke through the chain of their arms and hurried on. They would have followed, but a black mask caught the ringleader and whispered in his ear, and the laughing gnomes fell back murmuring together.

The Duke was still dallying with the blue domino; Wilhelmine saw him lead her to one of the windows which opened out on to the terraces. She followed swiftly, hardly hearing the comments and whispers of the revellers who took this occasion to convey insulting words to the hated woman. As she reached the window in whose balcony she knew her lover to be, she felt a hand on her arm. She turned angrily.

'What do you want? how dare you hinder me?' she said. It was a tall, thin domino who accosted her, entirely black, and with a skull and crossbones embroidered in white upon the breast. A startling figure, and to Wilhelmine's overwrought nerves it seemed to be the figure of Death come to snatch her life's glory and happiness from her in this her triumph of the completion of the palace.

'What do you want of me?' she said again, conquering her superstitious fear.

'I would speak to you, Madame; I have a warning to give you.' The voice was deep and low, and after the squeaky tones which the revellers affected in order to disguise their natural voices, this man's bass notes sounded hollow and funereal.

'Speak then here,' she answered.

'No; my warning must be given to you where none can hear,' he responded; and once more laying his black-gloved hand on her arm, he drew her away from the window towards a door which led down a short flight of steps into the moonlit garden. Did the man mean murder? It flashed across Wilhelmine that she was going blindly into danger. She paused on the topmost step of the flight.
