A tall, gray-bearded man, who from the first had attached himself to Ruff, and who seemed to act as a sort of master of ceremonies, now approached him once more and laid his hand upon his shoulder.

“Mon ami,” he said, “we will now discuss, if it pleases you, the little matter concerning which we took the liberty of asking you to favor us with a visit.”

“What, here?” Peter Ruff asked, in some surprise.

His friend, who had introduced himself as Monsieur de Founcelles, smiled.

“But why not?” he asked. “Ah, but I think I understand!” he added, almost immediately. “You are English, Monsieur Peter Ruff, and in some respects you have not moved with the times. Confess, now, that your idea of a secret society is a collection of strangely attired men who meet in a cellar, and build subterranean passages in case of surprise. In Paris, I think, we have gone beyond that sort of thing. We of the ‘Double-Four’ have no headquarters save the drawing-room of Madame; no hiding-places whatsoever; no meeting-places save the fashionable cafes or our own reception rooms. The police follow us—what can they discover?—nothing! What is there to discover?—nothing! Our lives are lived before the eyes of all Paris. There is never any suspicion of mystery about any of our movements. We have our hobbies, and we indulge in them. Monsieur the Marquis de Sogrange here is a great sportsman. Monsieur le Comte owns many racehorses. I myself am an authority on pictures, and own a collection which I have bequeathed to the State. Paris knows us well as men of fashion and mark—Paris does not guess that we have perfected an organization so wonderful that the whole criminal world pays toll to us.”

“Dear me,” Peter Ruff said, “this is very interesting!”

“We have a trained army at our disposal,” Monsieur de Founcelles continued, “who numerically, as well as in intelligence, outnumber the whole force of gendarmes in Paris. No criminal from any other country can settle down here and hope for success, unless he joins us. An exploit which is inspired by us cannot fail. Our agents may count on our protection, and receive it without question.”

“I am bewildered,” Peter Ruff said, frankly. “I do not understand how you gentlemen—whom one knows by name so well as patrons of sport and society, can spare the time for affairs of such importance.”

Monsieur de Founcelles nodded.

“We have very valuable aid,” he said. “There is below us—the ‘Double-Four’—the eight gentlemen now present, an executive council composed of five of the shrewdest men in France. They take their orders from us. We plan, and they obey. We have imagination, and special sources of knowledge. They have the most perfect machinery for carrying out our schemes that it is possible to imagine. I do not wish to boast, Mr. Ruff, but if I take a directory of Paris and place after any man’s name, whatever his standing or estate, a black cross, that man dies before seven days have passed. You buy your evening paper—a man has committed suicide! You read of a letter found by his side: an unfortunate love affair—a tale of jealousy or reckless speculation. Mr. Ruff, the majority of these explanations are false. They are invented and arranged for by us. This year alone, five men in Paris, of position, have been found dead, and accounted, for excellent reasons, suicides. In each one of these cases, Monsieur Ruff, although not a soul has a suspicion of it, the removal of these men was arranged for by the’ Double-Four.’”
