His note written, Prosper folded it carefully into the smallest possible size, and after furtively glancing toward the detective, who remained motionless in his corner, threw it across the desk to little Cavaillon with this one word:

“Gypsy!”

All this was so quickly and skilfully done that Fanferlot was confounded, and began to feel a little uneasy.

“The devil take him!” said he to himself; “for a suffering innocent this young dandy has more pluck and nerve than many of my oldest customers. This, however, shows the result of education!”

Yes: innocent or guilty, Prosper must have been endowed with great self-control and power of dissimulation to affect this presence of mind at a time when his honor, his future happiness, all that he held dear in life, were at stake. And he was only thirty years old.

Either from natural deference, or from the hope of gaining some ray of light by a private conversation, the commissary determined to speak to the banker before acting decisively.

“There is not a shadow of doubt, monsieur,” he said, as soon as they were alone, “this young man has robbed you. It would be a gross neglect of duty if I did not secure his person. The law will decide whether he shall be released, or sent to prison.”

The declaration seemed to distress the banker.

He sank into a chair, and murmured:

“Poor Prosper!”
