“As sure as that you are standing there! This morning, at half-past ten o’clock, Mademoiselle Stangerson, in the cleverest way in the world, arranged to have no nurses to-night. She gave them leave of absence for twenty-four hours, under some plausible pretexts, and did not desire anybody to be with her but her father, while they are away. Her father, who is to sleep in the boudoir, has gladly consented to the arrangement. Darzac’s departure and what he told me, as well as the extraordinary precautions Mademoiselle Stangerson is taking to be alone to-night leaves me no room for doubt. She has prepared the way for the coming of the man whom Darzac dreads.”

“That ’s awful!”

“It is!”

“And what we saw her do was done to send her father to sleep?”

“Yes.”

“Then there are but two of us for to-night’s work?”

“Four; the concierge and his wife will watch at all hazards. I don’t set much value on them before—but the concierge may be useful after—if there ’s to be any killing!”

“Then you think there may be?”

“If he wishes it.”

“Why have n’t you brought in Daddy Jacques?—Have you made no use of him to-day?”
