“I am the nephew of a messenger at the Palais de Justice,” replied Lecoq with an awkward bow, in perfect keeping with his attire. “On going to see my uncle this morning, I found him laid up with rheumatism; and he asked me to bring you this paper in his stead. It is a summons for you to appear at once before the investigating magistrate.”

This reply induced Madame Milner to abandon her perch. “Very well,” she replied after glancing at the summons; “give me time to throw a shawl over my shoulder, and I’ll start.”

Lecoq withdrew with another awkward bow; but he had not reached the street before a significant grimace betrayed his inward satisfaction. She had duped him once, and now he had repaid her. On looking round him he perceived a half-built house at the corner of the Rue St. Quentin, and being momentarily in want of a hiding-place he concluded that he had best conceal himself there. The pretty widow had only asked for sufficient time to slip on a shawl before starting; but then it so happened that she was rather particular as to her personal appearance—and such a plump, attractive little body as herself, having an eye perhaps to renewed wedlock, could not possibly be expected to tie her bonnet strings in less than a quarter of an hour. Hence, Lecoq’s sojourn behind the scaffolding of the half-built house proved rather longer than he had expected, and at the thought that May might arrive at any moment he fairly trembled with anxiety. How much was he in advance of the fugitive? Half an hour, perhaps! And he had accomplished only half his task.

At last, however, the coquettish landlady made her appearance as radiant as a spring morning. She probably wished to make up for the time she had spent over her toilet, for as she turned the corner she began to run. Lecoq waited till she was out of sight, and then bounding from his place of concealment, he burst into the Hotel de Mariembourg like a bombshell.

Fritz, the Bavarian lad, must have been warned that the house was to be left in his sole charge for some hours; for having comfortably installed himself in his mistress’s own particular armchair, with his legs resting on another one, he had already commenced to fall asleep.

“Wake up!” shouted Lecoq; “wake up!”

At the sound of this voice, which rang like a trumpet blast, Fritz sprang to his feet, frightened half out of his wits.

“You see that I am an agent of the Prefecture of Police,” said the visitor, showing his card. “Now, if you wish to avoid all sorts of disagreeable things, the least of which will be a sojourn in prison, you must obey me.”

The boy trembled in every limb. “Yes, mein Herr—Monsieur, I mean—I will obey you,” he stammered. “But what am I to do?”

“Oh, very little. A man is coming here in a moment: you will know him by his black clothes and his long beard. You must answer him word for word as I tell you. And remember, if you make any mistake, you will suffer for it.”
