"What's that?" I queried, mystified at his actions.

"Something the French secret service spies call the 'bad perfume,'" he returned frankly, "an anesthetic so incredibly rapid and violent that the spies, usually women, who use it wear a filter veil over their own mouths and noses to protect themselves."

The whole thing was so queer that I could only wonder what might be the explanation. Cecilie was protesting volubly, now in fair English, now in liquid French, that she knew absolutely nothing of the articles.

I wondered whether Rawaruska herself might not have placed them there. Might she not have been a spy, one of those clever little dancers who had wormed themselves by their graceful agility into the good graces of some of the world's leading men and made Russia a recognized diplomatic power?

Something like the same idea must have been suggested to Dr. Sanderson, who was standing next me, for he bent over and remarked to me in an undertone, with a significant glance at what Kennedy had discovered, "I suppose you realize that the position of the Russian government has undergone a marked change since the Russian dancers have won international popularity?"

I had not thought much about it before, but now that he mentioned it, I could not help a nod of assent.

"Why, I have heard," he continued with the air of a man who is imparting a big piece of information, "that the beautiful young women of the imperial ballet mingle in the society of the capitals of the world, make friends with politicians, social leaders, high officials, and exert a great influence in favor of their own country wherever they go. No doubt," he added, "they sometimes convey valuable information to the Foreign Office which could not be obtained in any other way."

I was not paying much attention to him, but still the doctor rattled on in an undertone, "Some of these dancers are past masters in the art of intrigue. Do you suppose Rawaruska and the rest have had the task set for them to win back the public opinion of your country, which departed from its traditional policy of friendliness during the Japanese war?"

I made no answer. I was engrossed in considering the primary question. Could it have been a suicide, after all? Surely she had removed the evidences of it much better than in any other case I had ever seen.

Or, had there been a "triangle," perhaps a quadrangle here? I could not persuade myself that De Guerre cared greatly for his wife, except perhaps to be jealous of anyone else having her. He was too attentive to Elsa Hoffman, and she, in turn, was not of the type to care much for anyone. As for Dr. Preston, although he seemed to have had a friendship for Rawaruska, I could not exactly fit him into the scheme of things.
