“On what day are those others coming?”
“Wednesday—Tuesday perhaps—”
Beautrelet seemed to be making an inward calculation and then declared:
“Monsieur le Juge d’Instruction, this is Saturday. I have to be back at school on Monday evening. Well, if you will have the goodness to be here at ten o’clock exactly on Monday morning, I will try to give you the key to the riddle.”
“Really, M. Beautrelet—do you think so? Are you sure?”
“I hope so, at any rate.”
“And where are you going now?”
“I am going to see if the facts consent to fit in with the general theory which I am beginning to perceive.”
“And if they don’t fit in?”
“Well, Monsieur le Juge d’Instruction,” said Beautrelet, with a laugh, “then it will be their fault and I must look for others which, will prove more tractable. Till Monday, then?”
