Castanier had gone himself to shut the door which opened on to a staircase that led to the parlor occupied by the two bankers on the first floor of their hotel.  This done, he had sat down at his desk again, and for a moment he gazed at a little collection of letters of credit drawn on the firm of Watschildine of London.  Then he had taken up the pen and imitated the banker’s signature upon each. Nucingen he wrote, and eyed the forged signatures critically to see which seemed the most perfect copy.

Suddenly he looked up as if a needle had pricked him.  “You are not alone!” a boding voice seemed to cry in his heart; and indeed the forger saw a man standing at the little grated window of the counting-house, a man whose breathing was so noiseless that he did not seem to breathe at all.  Castanier looked, and saw that the door at the end of the passage was wide open; the stranger must have entered by that way.

For the first time in his life the old soldier felt a sensation of dread that made him stare open-mouthed and wide-eyed at the man before him; and for that matter, the appearance of the apparition was sufficiently alarming even if unaccompanied by the mysterious circumstances of so sudden an entry.  The rounded forehead, the harsh coloring of the long oval face, indicated quite as plainly as the cut of his clothes that the man was an Englishman, reeking of his native isles.  You had only to look at the collar of his overcoat, at the voluminous cravat which smothered the crushed frills of a shirt front so white that it brought out the changeless leaden hue of an impassive face, and the thin red line of the lips that seemed made to suck the blood of corpses; and you could guess at once at the black gaiters buttoned up to the knee, and the half-puritanical costume of a wealthy Englishman dressed for a walking excursion.  The intolerable glitter of the stranger’s eyes produced a vivid and unpleasant impression, which was only deepened by the rigid outlines of his features.  The dried-up, emaciated creature seemed to carry within him some gnawing thought that consumed him and could not be appeased.

He must have digested his food so rapidly that he could doubtless eat continually without bringing any trace of color into his face or features.  A tun of Tokay vin de succession would not have caused any faltering in that piercing glance that read men’s inmost thoughts, nor dethroned the merciless reasoning faculty that always seemed to go to the bottom of things.  There was something of the fell and tranquil majesty of a tiger about him.

“I have come to cash this bill of exchange, sir,” he said.  Castanier felt the tones of his voice thrill through every nerve with a violent shock similar to that given by a discharge of electricity.

“The safe is closed,” said Castanier.

“It is open,” said the Englishman, looking round the counting-house.  “To-morrow is Sunday, and I cannot wait.  The amount is for five hundred thousand francs.  You have the money there, and I must have it.”
