My Chief sauntered by, chatting with his close personal friend, Prince Olsoufieff, the Russian Ambassador, who looked a truly striking figure in his white uniform, with the Cross of St. Andrew glittering at his throat. The latter, as he passed, exclaimed confidentially in Russian to my Chief, who understood that language, having been first Secretary of Embassy in Petersburg earlier in his career:

“Da, ya po-ni-mai-ù. Ya sam napishu.” (“Yes, I understand. I will write for you myself.”)

Keen antagonists in diplomacy though they very often were, yet in private life a firm friendship existed between the pair—a friendship dating from the days when the one had been British Attaché in Petersburg and the other had occupied a position in the Russian Ministry of Foreign Affairs—that large grey building facing the Winter Palace.

“The lion and the bear strolling together,” laughed the toothless old Baronne, after they had passed. “Olsoufieff is a charming man, but he never accepts my invitations. I cannot tell why. I don’t fancy he considers me his friend.”

“Sibyl was at your reception the other evening,” I remarked suddenly. “She told me she met a man who was a stranger in Paris. His name, I think she said, was Wolf—Rodolphe Wolf. Who is he?”

“He was introduced by de Wolkenstein, the Austrian Ambassador,” she replied quickly. “I did not know him.”

“Have you never met him before?” I asked, looking sharply into her eyes.

“Once, I think, but I am not certain,” she said, with a palpable effort to evade my question.

I smiled.

“Come, madame,” I said good-humouredly, “you know Rodolphe Wolf quite as well as I do. When you last met, his name was not Wolf. Is not that so?”
