THE MYSTERY OF THE YELLOW ROOM

"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 haven't you brought in Daddy Jacques?—Have you made no use of him to-day?"
"No," replied Rouletabille sharply.
I kept silence for awhile, then, anxious to know his thoughts, I asked him point blank:
"Why not tell Arthur Rance?—He may be of great assistance to us?"
"Oh!" said Rouletabille crossly, "then you want to let everybody into Mademoiselle Stangerson's secrets?—Come, let us go to dinner; it is time. This evening we dine in Frédéric Larsan's room,—at least, if he is not on the heels of Darzac. He sticks to him like a leech. But, anyhow, if he is not there now, I am quite sure he will be, to-night! He's the one I am going to knock over!"
