“Absolutely,” I responded. “All my efforts have unfortunately failed.”
“And you entertain no suspicion of anyone?”
“None whatever.”
“Not of that woman Yolande – or whatever her name is?”
“Certainly not of her,” I answered quickly. “She would assist us, if necessary.”
“Why are you so sure of that? She has only been in Paris a week.”
“Because I happen to know her.”
“You know her!” exclaimed His Excellency, unclasping his thin white hands and leaning across his big writing-table – a habit of his when suddenly interested. “Is she a personal friend of yours?”
I hesitated for a moment; then replied in the affirmative.
