At first he did not fully grasp that the Madame of that Sunday, the real Madame, was wholly different from the one he had known before. As they sat together upon the cliffs towards Rottingdean, he slipped his arm about her waist. Gently, but very decidedly, she removed it. "No, mon ami," said she. "All that has passed with the necessity for its exercise. I do not play with my friends."

"Thank you," replied he—it was the brightest speech which Madame has recorded of him. There is hope that Rust will, with years and experience, develop in intelligence.

When Madame returned to London on the Monday, she sought an audience of Chief Inspector Dawson, and told the whole story. He was not pleased, but handsomely conceded that she had carried out her duties with skill and enterprise. "The farce was not your fault," said he; "it was entirely due to that French ass Froissart, who has no right to play games of his own without consulting me. I will make a protest to the Chief."

"Don't do that," urged Madame. "Froissart is rather a dear, and you know that the fault was partly yours, for not taking him into your confidence. I have determined to cultivate Froissart, and shall endeavour to persuade him that your feminine assistants are not all of microscopic intelligence and of repulsive appearance."

"You will succeed," said Dawson handsomely.

Froissart, to whom Rust reported, gleaned some consolation from the failure of his agent. "This wonder of a woman, of whom I must instantly make the honourable acquaintance, has saved the detested Dawson from the deeps of humiliation. But we have scored off him most surely. He has shown himself to be a blundering, conceited English pig, and I will protest to the Chief that never again must he keep me in ignorance of his projects. I shall laugh at him; all our people here will laugh. I shall be revenged. Conspuez Dawson!"

"Don't be too hard on Dawson," urged Rust. "Madame Gilbert thinks a lot of him, and would be pained if he suffered discredit through any fault of hers."

"Fault!" shouted the gallant Froissart. "La belle Madame is sans faute, peerless, a prodigy of skill and discretion! She is superb. If she implores me to spare the man Dawson, then I will consent, though my heart is rent in fragments. As for you, mon ami, I fear that in her hands you were not a figure of admiration. She twisted you about her pretty fingers like a skein of wool. I do not think that you are, what you call, cut out for the Secret Service."

"That is quite my own opinion," assented he gloomily.
