M. Masseron bowed; and Don Luis at once began, speaking with a slight accent:

“Sir, your time is valuable and so is mine, for I am leaving Paris to-night and France to-morrow. My explanation therefore will be brief. I will pass over the drama itself, of which you have followed the main vicissitudes so far. It came to an end this morning. Captain Belval will tell you all about it. I will merely add that our poor Ya-Bon is dead and that you will find three other bodies: that of Grégoire, whose real name was Mme. Mosgranem, in the barge over there; that of one Vacherot, a hall-porter, in some corner of a block of flats at 18, Rue Guimard; and lastly the body of Siméon Diodokis, in Dr. Géradec’s private hospital on the Boulevard de Montmorency.”

“Old Siméon?” asked M. Masseron in great surprise.

“Old Siméon has killed himself. Captain Belval will give you every possible information about that person and his real identity; and I think you will agree with me that this business will have to be hushed up. But, as I said, we will pass over all this. There remains the question of the gold, which, if I am not mistaken, interests you more than anything else. Have you brought your men?”

“Yes, I have. But why? The hiding-place, even after you have told me where it is, will be what it was before, undiscovered by those who do not know it.”

“Certainly; but, as the number of those who do know it increases, the secret may slip out. In any case that is one of my two conditions.”

“As you see, it is accepted. What is the other?”

“A more serious condition, sir, so serious indeed that, whatever powers may have been conferred upon you, I doubt whether they will be sufficient.”

“Let me hear; then we shall see.”

“Very well.”
