“Monsieur?” This simple formula of politeness brought a faint smile to his lips. Was it not, on Father Absinthe’s part, an evident recognition of his colleague’s superiority. Indeed, our hero accepted it as a token of unquestioning devotion which it would be his duty to repay with a master’s kind protection toward his first disciple. However, he had no time to waste in thought, and accordingly at once proceeded to peruse the note, which ran as follows:

“Monsieur Lecoq—I had been standing on duty since the opening of the Morgue, when at about nine o’clock three young men entered, arm-in-arm. From their manner and appearance, I judged them to be clerks in some store or warehouse. Suddenly I noticed that one of them turned as white as his shirt; and calling the attention of his companions to one of the unknown victims, he whispered: ‘Gustave!’

“His comrades put their hands over his mouth, and one of them exclaimed: ‘What are you about, you fool, to mix yourself up with this affair! Do you want to get us into trouble?’

“Thereupon they went out, and I followed them. But the person who had first spoken was so overcome that he could scarcely drag himself along; and his companions were obliged to take him to a little restaurant close by. I entered it myself, and it is there I write this letter, in the mean time watching them out of the corner of my eye. I send this note, explaining my absence, to the head keeper, who will give it you. You will understand that I am going to follow these men. A. B. S.”

The handwriting of this letter was almost illegible; and there were mistakes in spelling in well-nigh every line; still, its meaning was clear and exact, and could not fail to excite the most flattering hopes.

Lecoq’s face was so radiant when he returned to the cab that, as the old coachman urged on his horse, he could not refrain from saying: “Things are going on to suit you.”

A friendly “hush!” was the only response. It required all Lecoq’s attention to classify this new information. When he alighted from the cab in front of the Palais de Justice, he experienced considerable difficulty in dismissing the old cabman, who insisted upon remaining at his orders. He succeeded at last, however, but even when he had reached the portico on the left side of the building, the worthy fellow, standing up, still shouted at the top of his voice: “At M. Trigault’s house—don’t forget—Father Papillon—No. 998—1,000 less 2—”

Lecoq had entered the left wing of the Palais. He climbed the stairs till he had reached the third floor, and was about to enter the long, narrow, badly-lighted corridor known as the Galerie de l’Instruction, when, finding a doorkeeper installed behind a heavy oaken desk, he remarked: “M. d’Escorval is, of course, in his office?”

The man shook his head. “No,” said he, “M. d’Escorval is not here this morning, and he won’t be here for several weeks.”

“Why not! What do you mean?”
