Angry with himself, Lecoq struck his clenched hand violently upon the table beside him. “Sacrebleu!” he exclaimed, “that method was infallible, and so simple too! Ah! I shall never forgive myself for my stupidity as long as I live!”
“Gently, gently!” interrupted old Tirauclair. “You are going too far, my dear boy. Stupidity is not the proper word at all; you should say carelessness, thoughtlessness. You are young—what else could one expect? What is far less inexcusable is the manner in which you conducted the chase, after the prisoner was allowed to escape.”
“Alas!” murmured the young man, now completely discouraged; “did I blunder in that?”
“Terribly, my son; and here is where I really blame you. What diabolical influence induced you to follow May, step by step, like a common policeman?”
This time Lecoq was stupefied. “Ought I to have allowed him to escape me?” he inquired.
“No; but if I had been by your side in the gallery of the Odeon, when you so clearly divined the prisoner’s intentions, I should have said to you: ‘This fellow, friend Lecoq, will hasten to Madame Milner’s house to inform her of his escape. Let us run after him.’ I shouldn’t have tried to prevent his seeing her, mind. But when he had left the Hotel de Mariembourg, I should have added: ‘Now, let him go where he chooses; but attach yourself to Madame Milner; don’t lose sight of her; cling to her as closely as her own shadow, for she will lead you to the accomplice—that is to say—to the solution of the mystery.’”
“That’s the truth; I see it now.”
“But instead of that, what did you do? You ran to the hotel, you terrified the boy! When a fisherman has cast his bait and the fish are swimming near, he doesn’t sound a gong to frighten them all away!”
Thus it was that old Tabaret reviewed the entire course of investigation and pursuit, remodeling it in accordance with his own method of induction. Lecoq had originally had a magnificent inspiration. In his first investigations he had displayed remarkable talent; and yet he had not succeeded. Why? Simply because he had neglected the axiom with which he started: “Always distrust what seems probable!”
But the young man listened to the oracle’s “summing up” with divided attention. A thousand projects were darting through his brain, and at length he could no longer restrain himself. “You have saved me from despair,” he exclaimed, “I thought everything was lost; but I see that my blunders can be repaired. What I neglected to do, I can do now; there is still time. Haven’t I the diamond earring, as well as various effects belonging to the prisoner, still in my possession? Madame Milner still owns the Hotel de Mariembourg, and I will watch her.”
