"Mme Allard! Why, she's fifty, and a widow!" objected M. Perrelet. "Stay, is it that cousin of hers I promised to attend? You are sure it is not a false alarm?

"Oh, no!" replied Laurent earnestly. "It's . . . an old patient of yours. If you will only come down I will explain. He's been having the most horrible shivering fits, and now——"

"He!" fairly bellowed M. Perrelet from the window. "He! Why did you not say at once that it was a man? For nothing but a confinement will I stir from this house to-night! Go away, wretched bucolic!" And he started furiously to draw down the window.

Now Laurent was indeed desperate. Having no stave that he might uplift, and fearing to hit M. Perrelet if he threw a stone, he swirled off the cloak that he wore and sent it flying window-wards. A good deal of its unsavoury bulk caught in the descending sash and stayed its progress. The window went up again with even more passion than had propelled its descent.

"What is this filthy object you have thrown up?" demanded M. Perrelet in a fury. "Pah! it stinks! I shall be infected with I know not what!" And he threw the offensive garment down again with all his force at its wearer.

But Laurent, still afraid to pronounce either his or Aymar's name, was now trying a different and more hazardous method of self-revelation. He stepped back across the narrow street and came under the light of the lamp on the other side, where, snatching off his hat, he exposed his features to its rays, M. Perrelet, and any one else whom the altercation might have drawn to their windows. And at the sight of this young man in a blouse, holding his hat rigidly at arm's length and pointing to his own face with the other hand, all M. Perrelet's powers of speech (fortunately) deserted him for the moment. He disappeared from the window without even shutting it, which Laurent took for a hopeful sign. Darting across to the door, he was standing just outside when it opened to reveal the doctor, now clad in a dressing-gown and with a candle in his hand.

He waved the intruder into the nearest room and then said in a resigned manner, "Now, perhaps, you will be good enough to explain, Monsieur de Courtomer, why you are serenading me. I presume you are on parole. It appears to be a masquerade as well . . . pfui! that garment again!" And holding his nose he added, "I will gladly contribute some bergamot to your costume."

"You can't object to it, sir, as much as I do, who have had its company for five miles," protested Laurent. "But let me discharge my errand, and then I will leave you at once, or I may get you into trouble. You obviously don't know that I escaped last night from the château!"

"The deuce you did! Why this curious fancy for Arbelles then, and this flattering midnight visit to my door? Ah, I forgot; you said you wanted me for someone or other."

"I do," said Laurent significantly, "and I'll tell you why!"
