longed to either of the deceased. Now if, after all, I am wrong in my induction from this ribbon, that the Frenchman was a sailor belonging to a Maltese vessel, still I can have done no harm in saying what I did in the advertisement. If I am in error, he will merely suppose that I have been misled by some circumstance into which he will not take the trouble to inquire. But if I am right, a great point is gained. Cognizant, although innocent, of the murder, the Frenchman will naturally hesitate about replying to the advertisement—about demanding the Ourang-outang. He will reason thus:—'I am innocent; I am poor; my Ourang-outang is of great value—to one in my circumstances a fortune of itself—why should I lose it through idle apprehensions of danger? Here it is, within my grasp. It was found in the Bois de Boulogne—at a vast distance from the scene of that butchery. How can it ever be suspected that the brute beast should have done the deed! The police are at fault—they have failed to procure the slightest clue. Should they even trace the animal, it would be impossible to prove me cognizant of the murder, or to implicate me in guilt on account of that cognizance. Above all, I am known. The advertiser designates me as the possessor of the beast. I am not sure to what limit his knowledge may extend. Should I avoid claiming a property of so great value, which it is known that I possess, I will render the animal at least liable to suspicion. It is not my policy to attract attention either to myself or to the beast. I will answer the advertisement, get the Ourang-outang, and keep it close until this matter has blown over."
At this moment we heard a step upon the stairs.
"Be ready," said Dupin, "with your pistols, but neither use them nor show them until at a signal from myself."
