"Signor Petito," he said, "I understand that you are a first-class expert in handwriting. I should be much obliged if you would examine this letter and this document, and inform me of the result of your examination. I assert myself that there is no connection—"

He stopped short, as red as a peony, for he was not in the habit of lying. But Signor Petito had already scanned the letter and the scrap of paper with the eye of an expert; and with a smile which showed all his exceedingly white teeth, he said:

"I won't keep you waiting for my answer, M. Longuet. The document is in a very bad state; but the scraps of handwriting one can read are in every respect the same as the handwriting of the letter. Before the Courts, M. Longuet, before God and before men, these two handwritings were traced by the same hand!" He laid his hand on his heart with a great air.

He entered into particulars: a child, he declared, could not make a mistake about it. He became oracular.

"The handwriting in both is equally angular," he said in a very pompous tone. "By angular, M. Longuet, we describe a handwriting in which the thin strokes which join the strokes of the letters and the letters to one another are at an acute angle. You understand? Look at this hook, and this one, and this thin stroke, and all these letters which increase progressively in equal proportions. But what an acute handwriting, M. Longuet! I have never seen handwriting so acute: it's as sharp as the blade of a knife!"

At these last words Theophrastus turned so pale that Signor Petito thought that he was going to faint. None the less he took the letter and the document, thanked Signor Petito, and went out of the flat.

He walked straight out of the house and wandered about the streets for a long while. At last he found himself in Saint-Andrew-des-Arts Place; then he took his way to Suger Street, and opened the latch of an old-fashioned door. He found himself in a dark and dirty passage. A man came down it to meet him, and recognising him, greeted him.

"How are you, Theophrastus? What good wind blows you here?" he said in affectionate tones.

"How are you, Ambrose?" said Theophrastus gloomily.

Since they had not met for two years, they had a hundred inquiries to make of one another. Ambrose was an engraver of visiting-cards by profession. He had been a printer in the Provinces; but having put all his capital into a new invention in printing, it had not been long before he found himself a bankrupt. He was a cousin of Marceline; and Theophrastus, who was a good soul, had come to his aid in the hour of his gravest trouble.
