In another instant they were among the crowd of dancers in the ball room. Neither knew exactly how they happened to get there. Pembroke did not often dance, and was rather surprised when he found himself whirling around the ball room with Olivia, to the rhythm of a dreamy waltz. It was soon over. It came back to Olivia that she ought not so soon to part company with the De Peysters, and she stopped at once, thereby cutting short her own rapture as well as Pembroke’s. Without a word, Pembroke led her back to where the Colonel and Mrs. De Peyster and Helena were. Helena’s pretty face wore a cloud. She had not yet been asked to dance, and was more puzzled than pleased at the meeting which she had witnessed in all its strangeness. Pembroke good naturedly took her for a turn and brought her back with her card half filled and the smiles dimpling all over her face. Meanwhile, the ball went on merrily. Ryleief escaped from his post as soon as possible and sought Pembroke. “So you knew M. Volkonsky?” he said eagerly, in a whisper. “Yes,” said Pembroke--and his look and tone expressed volumes. Ryleief held him by the arm, and whispered: “This is confidential. I suspected from the first that our new chief was--eh--you know--not exactly--” “Yes,” answered Pembroke, “not exactly a gentleman. An arrant knave and coward, in short.” Ryleief, a mature diplomatic sprig, looked fixedly at Pembroke, his hard Muscovite face growing expressive. “Speaking as friends, my dear Pembroke--and, you understand in my position the necessity of prudence--M. Volkonsky is not unknown among the Russian diplomats. He has been recalled once--warned repeatedly. Once, some years ago, it was supposed he had been dismissed from the diplomatic corps. But he reappeared about five years ago under another name--he was originally an Ahlberg. He certainly inherited some money, married some more, and took the name of Volkonsky--said it was a condition of his fortune. He has been _chargé d’affaires_ at Munich--later at Lisbon--both promotions for him. What his power is at the Foreign Office I know not--certainly not his family, because he has none. It is said he is a Swiss.” “He will not be long here,” remarked Pembroke. Then Pembroke went away and wandered about, feeling uncomfortable, as every man does, under the same roof as his enemy. He felt no compunction as to being the guest of Volkonsky. The legation was Russian property--the ball itself was not paid for out of Volkonsky’s own pocket, but by his government. Pembroke felt, though, that when it came out, as it must, the part that he would take in exposing the Russian Minister, his presence at the ball might not be understood, and he would gladly have left the instant he found out who Volkonsky really was but for the Berkeleys and the De Peysters.
