Yet the order of his craft was strong in its influence, and he commenced another series of protestations.
"I assure you, gentlemen," he cried, "that with respect to the Turks I have no knowledge whatever of their pursuits or motives. I was present when this English gentleman here was debating with them, and I understood that they even went so far as to use threats against him. My mission was to give to the leaders of the Turks a package which I did not even know contained diamonds, either genuine or false. No one could be more surprised than myself when the Turkish gentleman produced them."
"Who sent you there with the diamonds?" said Brett.
"Even that I cannot tell you," said Petit. "It was a mere chance affair. I was seated in a café sipping some absinthe when a man asked me if I would execute a small commission for him. He explained that it was to deliver a parcel at a house not five minutes distant, and——"
"I see," interrupted Brett, with the cynical smile which so often disconcerted glib liars like Petit. "It is hopeless to expect you to tell the truth. However, I think I know a way to clear your wits. You must be brought face to face with La Belle Chasseuse. Perhaps when you are confronted with that lady in the room between the café and the billiard saloon of the Cabaret Noir——"
"The Worm" gasped out brokenly—
"Pardon, monsieur! I will tell you everything!"
The man's face had absolutely become livid as he listened to the barrister's words.
The commissary was vastly surprised at the turn taken by the conversation. He could not guess what deep significance lay behind the Englishman's threat, and, to tell the truth, Brett himself was considerably astonished at the effect of his vague insinuations, but he lost not a moment in following up the advantage thus gained.
