“Having indicated to Daddy Jacques the post he was to occupy, and having seen him take up his position, I placed Monsieur Stangerson on the landing at the head of the stairs not far from the door of his daughter’s ante-room. Everything led me to suppose that when I surprised the murderer in the room, he would run by way of the ante-room, rather than the boudoir, where the women were, and of which the door must have been locked by Mademoiselle Stangerson herself if, as I thought, she had taken refuge in the boudoir for the purpose of avoiding the murderer who was coming to see her. In any case, he must return to the gallery where my people were awaiting him at every possible issue. “On coming there, he would see on his left, Monsieur Stangerson; he would turn to the right, towards the ‘off-turning’ gallery—the way he had pre-arranged for flight, where, at the intersection of the two galleries, he would see at once, as I have explained, on his left, Frédéric Larsan at the end of the ‘off-turning’ gallery, and in front, Daddy Jacques, at the end of the ‘right’ gallery. Monsieur Stangerson and myself would arrive by way of the back of the château.—He is ours!—He can no longer escape us! I was sure of that. “The plan I had formed seemed to me the best, the surest, and the most simple. It would, no doubt, have been simpler still, if we had been able to place some one directly behind the door of Mademoiselle’s boudoir, which opened out of her bedchamber, and, in that way, had been in a position to besiege the two doors of the room in which the man was. But we could not penetrate the boudoir except by way of the drawing-room, the door of which had been locked on the inside by Mademoiselle Stangerson. But even if I had had the free disposition of the boudoir, I should have held to the plan I had formed; because any other plan of attack would have separated us at the moment of the struggle with the man, while my plan united us all for the attack, at a spot which I had selected with almost mathematical precision,—the intersection of the two galleries. “Having so placed my people, I again left the château, hurried to my ladder, and, replacing it, climbed up, revolver in hand.
