"Impenetrable reticence," the Count expounded, sententious—and enjoying himself hugely—"isn't possible in the human relations. Sooner or later one is doomed to share one's secrets, however reluctantly, even unconsciously, with a wife, a mistress, a child, or with some trusted friend. And a secret between two is—a prolific breeder of platitudes! Granted this line of reasoning, the Lone Wolf is of necessity not only unmarried but practically friendless. Other attributes of his will obviously comprise youth, courage, imagination, a rather high order of intelligence, and a social position—let us say, rather, an ostensible business—enabling him to travel at will hither and yon without exciting comment. So far, good! My friend the Chief of the Sûreté forthwith commissioned his agents to seek such an one, and by this means several fine fish were enmeshed in the net of suspicion, carefully scrutinized, and one by one let go—all except one, the veritable man. Him they sedulously watched, shadowing him across Europe and back again. He was in Berlin at the time of the famous Rheinart robbery, though he compassed that coup without detection; he was in Vienna when the British embassy there was looted, but escaped by a clever ruse and managed to dispose of his plunder before the agents of the Sûreté could lay hands on him; recently he has been in London, and there he made love to, and ran away with, the diamonds of a certain lady of some eminence. You have heard of Madame Omber, eh?" Now by Roddy's expression it was plain that, if Madame Omber's name wasn't strange in his hearing, at least he found this news about her most surprising. He was frankly staring, with a slackened jaw and with stupefaction in his blank blue eyes.

Lanyard gently pinched the small end of a cigar, dipped it into his coffee, and lighted it with not so much as a suspicion of tremor. His brain, however, was working rapidly in effort to determine whether De Morbihan meant this for warning, or was simply narrating an amusing yarn founded on advance information and amplified by an ingenious imagination. For by now the news of the Omber affair must have thrilled many a Continental telegraph-wire….

"Madame Omber—of course!" the American agreed thoughtfully. "Everyone has heard of her wonderful jewels. The real marvel is that the Lone Wolf neglected so shining a mark as long as he did."

"But truly so, monsieur!"

"And they caught him at it, eh?"

"Not precisely: but he left a clue—and London, to boot—with such haste as would seem to indicate he knew his cunning hand had, for once, slipped."

"Then they'll nab him soon?"

"Ah, monsieur, one must say no more!" De Morbihan protested. "Rest assured the Chief of the Sûreté has laid his plans: his web is spun, and so artfully that I think our unsociable outlaw will soon be making friends in the Prison of the Santé…. But now we must adjourn. One is sorry. It has been so very pleasant…."

A waiter conjured the bill from some recess of his waistcoat and served it on a clean plate to the American. Another ran bawling for the vestiaire. Roddy glued his gaze afresh to the Daily Mail. The party rose.

Lanyard noticed that the American signed instead of settling the bill with cash, indicating that he resided at Troyon's as well as dined there. And the adventurer found time to reflect that it was odd for such as he to seek that particular establishment in preference to the palatial modern hostelries of the Rive Droit—before De Morbihan, ostensibly for the first time espying Lanyard, plunged across the room with both hands outstretched and a cry of joyous surprise not really justified by their rather slight acquaintanceship.
