ollowed the money-bag greedily.

"Proofs!" she exclaimed, taking a small flat box from under her cloak,
and pushing it across to the doctor. "Proofs! there you will find one
proof that establishes my claim beyond the possibility of doubt."

The doctor opened the box, and looked at the wax mask inside it; then
handed it to D'Arbino, and replaced the bag of scudi on the table.

"The contents of that box seem certainly to explain a great deal," he
said, pushing the bag gently toward Brigida, but always keeping his,
hand over it. "The woman who wore the yellow domino was, I presume, of
the same height as the late countess?"

"Exactly," said Brigida. "Her eyes were also of the same color as the
late countess's; she wore yellow of the same shade as the hangings in
the late countess's room, and she had on, under her yellow mask, the
colorless wax model of the late countess's face, now in your friend's
hand. So much for that part of the secret. Nothing remains now to be
cleared up but the mystery of who the lady was. Have the goodness, sir,
to push that bag an inch or two nearer my way, and I shall be delighted
to tell you."

"Thank you, madam," said the doctor, with a very perceptible change in
his manner. "We know who the lady was already."

He moved the bag of scudi while he spoke back to his own side of the
table. Brigida's cheeks reddened, and she rose from her seat.

"Am I to understand, sir," she said, haughtily, "that you take advantage

"By no means, madam," rejoined the doctor. "We have covenanted to pay
the reward to the person who could give us the information we required."

"Well, sir! have I not given you part of it? And am I not prepared to
give you the whole?"

"Certainly; but the misfortune is, that another person has been
beforehand with you. We ascertained who the lady in the yellow domino
was, and how she contrived to personate the face of the late Countess
d'Ascoli, several hours ago from another informant. That person has
consequently the prior claim; and, on every principle of justice, that
person must also have the reward. Nanina, this bag belongs to you--come
and take it."

Nanina appeared from the window-seat. Brigida, thunderstruck, looked
at her in silence for a moment; gasped out, "That girl!"--then stopped
again, breathless.

"That girl was at the back of the summer-house this morning, while you
and your acc
