'I know what I am doing, mon Prince,' she said calmly.

As at Güstrow, when Müller had attacked her, she now narrowed her lids and forced her will into her eyes. Gradually she felt her mastery working on Mélac; his jaws dropped, no longer fiercely baring the teeth but as though he had run a long distance, the whole mouth became weak, the red tongue protruding. With a whine the dog fell, his front paws slipping from the Duke's shoulders. Shuddering, the great animal crouched on the floor, his eyes still resting on Wilhelmine with an expression of abject terror.

'Lie quiet, Mélac! There—good dog!' She stroked his head, and the hound fawned upon her, dragging himself round her feet, crawling, abased.

Eberhard Ludwig caught her hand, and his own trembled a little. 'What an extraordinary thing! Did you put a spell upon Mélac? I have never seen him thus cowed! Beloved, I believe I owe my life to you this morning,' he said.

Wilhelmine passed her hand across her eyes. 'So may all your enemies be defeated!' she said, laughing.

'Could you make me tremble like that with your wonderful eyes?' he asked. He was fascinated, yet there was something terrible to him in this woman's power.

'Mon Prince, you are my master always,' she returned; and the subtle flattery of being the avowed ruler of so potent a being delighted him, as it pleases all men, who are obviously slaves, to be called master by the woman who controls them.

'Alas! but I am not the master of destiny,' he said sadly, 'and I come this morning to prove it. Wilhelmine, beloved, I must return to the army. We have information that Villars is to invade Wirtemberg once more, and I must be with the forces.'

'Is our happiness over then?' she queried.

'Ah! no, no, beloved of my life! You will wait for me here, I shall return in a few months.'
