“Ah, yes, I remember?” cried George, amazed. “It was my father’s unhappy second marriage that had caused him to become gloomy, misanthropic, and a hater of womankind. The subject was scarcely ever mentioned between us, but now I distinctly remember that the lady’s name was Holroyde. I knew that she had a son, but have always been led to suppose that he died when only a few months old.”

“No,” Mariette replied. “He was foully murdered for the money he had won at roulette by that man standing there,” and she pointed towards Zertho, who stood trembling, crushed by her terrible denunciation.

“Fancy poor Charlie Holroyde actually being your brother!” Liane exclaimed, looking up tenderly into the face of the man she so fondly loved. “Yet it is not surprising, for, strangely enough, I have many times thought that your face strongly resembled his. But my father is cleared of the terrible stigma, and no suspicion can now be cast upon me, therefore we have nothing to fear.”

“True, darling,” he answered. “We have nothing to fear, save one thing.”

“What is that?” she inquired eagerly.

He hesitated. His words were overheard by all in the room, and every eye was upon him. The man accused moved across to the table and stood leaning against it, swaying unsteadily. His passage was still barred resolutely.

“You forget the offer of marriage which, under my father’s will, I am compelled to make to Mariette, if I am not to remain a pauper all my days.”

As he spoke there was a quick movement behind him, a flood of golden sunlight suddenly lit up the room as the jalousies of one of the windows were dashed open, and as he turned he saw the figure of Zertho disappearing through the window.

With a cry, the fugitive leaped down upon the flower-bed outside, hat in hand, and an instant later had gained the road and was flying down through the fortifications towards La Condamine.

For scarcely a second Max Richards hesitated, then rushed after him to give him into the hands of the police. Zertho had long been watching his opportunity, and, being strong and athletic, had reached the window at a single bound, and had escaped almost before they could realise what had occurred.
