Louis tapped his forehead smartly, as if he were knocking at the door of memory.

"Tiens, tiens, tiens! I heard it often—it was some term of endearment. Tiens! It was Pig!"

"Pig!—Pigs are for good luck. I wonder what kind of luck this one will bring Colonel——Randall. And what did she call him? Another term of endearment?"

"She called him sometimes Dick, but the most often Ranny. When they were good friends, bien entendu. There were days when she would not address him the word. Elle savait comment se faire valoir!"

"They generally do know that, when they spring from the gutter," said Faunce.

He had learnt a good deal. Such a woman—with such beauty, dash, devilry—ought to be traceable in London, Paris, or New York, anywhere. He told himself that it might take him a long time to find her—or time that would be long for him, an adept in rapid action—but he felt very sure that he could find her, and that when he found her he could mould her to his will.

There was only one thing, Faunce thought, that would make her difficult—a genuine attachment to Rannock. If she really loved him, as such women can love, it might be hard work to induce her to betray him, even though no fatal consequences to him hung upon her secrecy. He knew the dogged fidelity which worthless women sometimes give to worthless men.

The hotel was almost empty, so after a prolonged siesta Mr. Faunce dined with the manager in the restaurant, which they had to themselves, while half a dozen tourists made a disconsolate little group in the desolation of the spacious dining-room.

Faunce did not pursue the subject of the Randalls and their behaviour during the social meal, for he knew that the manager's mind having been set going in that direction he would talk about them of his own accord, a surmise which proved correct, for M. Louis talked of nothing else; but there were no vital facts elicited over the bottle of Pommery which Mr. Faunce ordered.

"The lady was something of a slattern, you say?" said Faunce. "In that case she would be likely to leave things—odd gloves, old letters, trinkets—behind her. Now, in my work things are often of the last importance. Trifles light as air, mon ami, are sign-posts and guiding stars for the detective. You may remember Müller's hat—his murdered victim's, with the crown cut down—thriftiness that cost the German youth dear. I could recall innumerable instances. Now, did not this lady leave some trifling trail, some litter of gloves, fans, letters, which your gallantry would treasure as a souvenir?"
