anferlot was of the same opinion, but he had no idea of betraying his
private thoughts; and yet for the success of his investigations it was
necessary to impress the importance of prudence and discretion upon the
young man. He would have told him to keep silent concerning what had
passed between them, but he dared not.

"What you say may be true," he said. "I hope it is, for the sake of M.
Bertomy, and on your own account too; for, if he is guilty, you will
certainly be very much annoyed, and perhaps suspected of complicity, as
you are well known to be intimate with him."

Cavaillon was overcome.

"Now you had best take my advice, monsieur, and return to your business,
and--. Good-morning, monsieur."

The poor fellow obeyed. Slowly and with swelling heart he returned
to the Rue Notre Dame de Lorette. He asked himself how he could serve
Prosper, warn Mme. Gypsy, and, above all, have his revenge upon this

covered with a blue velvet carpet.

"Our cashier was certainly well lodged," murmured the detective.

But he had no time to purse his inventory. One of the door-curtains was
pushed aside, and Mme. Nina Gypsy stood before him.

Mme. Gypsy was quite young, small, and graceful, with a brown or rather
gold-colored quadroon complexion, with the hands and feet of a child.

Long curling silk lashes softened the piercing brilliancy of her large
black eyes; her lips were full, and her teeth were very white.

She had not yet made her toilet, but wore a velvet dressing-wrapper,
which did not conceal the lace ruffles beneath. But she had already been
under the hands of a hairdresser.

Her hair was curled and frizzed high on her forehead, and confined by
narrow bands
