“But do you suspect that she has had a hand in our latest betrayal?” I inquired a few minutes later. “You have just alleged that she is in the French service. If so, it hardly seems credible that she would give her information to the French Ambassador in Berlin.”

“On that point I am not yet absolutely certain,” Kaye responded. “I am, however, quite convinced that the exposure of our plans regarding Ceuta filtered to the French through their Embassy in Berlin.”

“Then, contrary to supposition, de Hindenburg, the German Ambassador here, may be assisting France against us?” I said in surprise.

“It seems much like it. Our inquiries all tend towards that theory. The German Ambassador has of late had almost daily interviews with the Minister of Foreign Affairs. These are generally believed to be in connection with the Samoan difficulty or the Transvaal; but without doubt the chief subject of discussion has been the formation of a plan whereby to checkmate our policy towards Spain in the matter of Ceuta.”

“Well, up to the present they have done so,” the Ambassador admitted, turning sharply upon his heel from the window, out of which he had been gazing moodily. “We appear to be arriving at a most critical stage, for what with the constant Anglophobe feeling here, the vile attacks of the Paris Press, the disgusting caricatures of Her Majesty and her subjects, and the army of spies surrounding us on every side, honest, straightforward diplomacy—the diplomacy which should preserve the peace of Europe—is well-nigh impossible. In all my career in the service I never knew a blacker outlook than at this moment—never, never!”

“The complications that have arisen are due entirely to spies,” I remarked.

“They are due, it appears, mainly to your friend, Yolande de Foville,” he said in a harsh voice. “We have to thank that interesting young lady for rendering all our diplomacy in that direction abortive.”

“You had suspicion of her the other day?” I exclaimed. “What caused you to suspect her?”

“Drummond knew her in Brussels, and mentioned her.”

“As a secret agent?”
