M. Domini rapped lightly on his desk to check the detective. As a man, the judge held too obstinately to his opinions; as a magistrate he was equally obstinate, but was at the same time ready to make any sacrifice of his self-esteem if the voice of duty prompted it. M. Lecoq's arguments had not shaken his convictions, but they imposed on him the duty of informing himself at once, and to either conquer the detective or avow himself conquered.
"You seem to be pleading," said he to M. Lecoq. "There is no need of that here. We are not counsel and judge; the same honorable intentions animate us both. Each, in his sphere, is searching after the truth. You think you see it shining where I only discern clouds; and you may be mistaken as well as I."
Then by an act of heroism, he condescended to add:
"What do you think I ought to do?"
The judge was at least rewarded for the effort he made by approving glances from M. Plantat and the doctor. But M. Lecoq did not hasten to respond; he had many weighty reasons to advance; that, he saw, was not what was necessary. He ought to present the facts, there and at once, and produce one of those proofs which can be touched with the finger. How should he do it? His active mind searched eagerly for such a proof.
"Well?" insisted M. Domini.
"Ah," cried the detective. "Why can't I ask Guespin two or three questions?"
The judge frowned; the suggestion seemed to him rather presumptuous. It is formally laid down that the questioning of the accused should be done in secret, and by the judge alone, aided by his clerk. On the other hand it is decided, that after he has once been interrogated he may be confronted with witnesses. There are, besides, exceptions in favor of the members of the police force. M. Domini reflected whether there were any precedents to apply to the case.
"I don't know," he answered at last, "to what point the law permits me to consent to what you ask. However, as I am convinced the interests of truth outweigh all rules, I shall take it on myself to let you question Guespin."
He rang; a bailiff appeared.
