"That being assumed as correct, the weight of the proof would seem to press upon the madame rather than upon Miss Ballister, wouldn't it?"

"Frankly I don't know. At times to-day, coming up here on the train, I have thought she must be the guilty one, and at times I have felt sure that she was not. But this much I do know: One of those two ladies is absolutely innocent of any wrongdoing, and the other one—pardon my language—is as guilty as hell. But perhaps it is only fair to both that you should suspend judgment altogether until I have finished telling you the whole business, as far as I know it.

"Let us go back a bit. Half an hour after I had heard Westerfeltner's confession and fifteen minutes after I had seen the druggist and his clerk, the entire machinery of our branch of the service had been set in motion to find out what women in Washington were friends of Geltmann. For Geltmann spent most of last fall in Washington. Now while in Washington he was noticeably attentive to just two women—Miss Ballister and Madame Ybanca. Now mark a lengthening of the parallel: Both of them are small women; both of them are slender; both are young, and both of course have refined voices. Neither speaks with any special accent, for the madame, though married to a Latin, is an American woman. She has black hair, while Miss Ballister's hair is a golden red-brown. So far, you see, the vague description furnished by the three men who spoke to the mythical Mrs. Williams might apply to either."

"Then which of the two is supposed to have been most attracted to Geltmann, as you call him?"

Mullinix smiled a trifle.

"I was rather expecting that question would come along about here," he said. "I only wish I could tell you; it might simplify matters. But so far as the available evidence points, there is nothing to indicate that either of them really cared for him or he for either of them. The attentions which he paid them both, impartially, were those which a man might pay to any woman, whether she was married or unmarried, without creating gossip. There is no suggestion here of a dirty scandal. The woman who is serving Geltmann's ends is doing it, not for love of him and not even because she is fascinated by him, but for money. She has agreed to sell out her country, the land she was born in, for hire. I'm sure of that much."

"Then which of them is presumed to be in pressing need of funds?"

"Again you score. I was expecting that question too. As a matter of fact both of them need money. Madame Ybanca belongs to a bridge-playing set—a group of men and women who play for high stakes. She has been a heavy loser and her husband, unlike many politically prominent South Americans, is not a fabulously wealthy man. I doubt whether he would be called wealthy at all, either by the standards of his own people or of ours. As for Miss Ballister, I have reports which prove she has no source of income except a modest allowance from her brother, the senator, who is in moderate circumstances only; yet it is common talk about Washington that she is extravagant beyond her means. She owes considerable sums to tradesmen for frocks and furs, millinery, jewelry and the like. It is fair to assume that she is harassed by her debts. On the other hand, Madame Ybanca undoubtedly wants funds with which to meet her losses at bridge. So the presumption in this direction runs as strongly against one as against the other."

"Well then, barring these slight clews—which to my way of thinking really aren't clews at all—and when you have eliminated the circumstance of Goldsborough's having paid perfectly proper attentions to both of them simultaneously, what is there to justify the belief that one or the other must be guilty?"

Miss Smith's voice still carried a suggestion of scepticism.
