"It is needless," said Leonard, "your looks answer for you. She "is"."

"Yes, yes, I confess she is," replied Chowles.

"You hear what he says, Sir Paul," remarked Leonard.

"His fears would make him assert anything," rejoined Parravicin, disdainfully. "If you do not depart instantly, I will drive you forth."

"Sir Paul Parravicin," rejoined Leonard, in an authoritative tone, "I command you in the king's name, to deliver up this girl."

Parravicin laughed scornfully. "The king has no authority here," he said.

"Pardon me, Sir Paul," rejoined Chowles, who began to be seriously alarmed at his own situation, and eagerly grasped at the opportunity that offered of extricating himself from it -- "pardon me. If it is the king's pleasure she should be removed, it materially alters the case, and I can be no party to her detention."

"Both you and your employer will incur his majesty's severest displeasure, by detaining her after this notice," remarked Leonard.

"Before I listen to the young man's request, let him declare that it is his intention to deliver her up to the king," rejoined Parravicin, coldly.

"It is my intention to deliver her up to one who has the best right to take charge of her," returned Leonard.

"You mean her father," sneered Parravicin.

"Ay, but not the person you suppose to be her father," replied Leonard. "An important discovery has been made respecting her parentage."

"Indeed!" exclaimed Parravicin, with a look of surprise. "Who has the honour to be her father?"

"A gentleman named Thirlby," replied Leonard.

"What!" cried Parravicin, starting, and turning pale. "Did you say Thirlby?"

The apprentice reiterated his assertion. Parravicin uttered a deep groan, and pressed his hand forcibly against his brow for some moments, during which the apprentice watched him narrowly. He then controlled himself by a powerful effort, and returned his sword to its scabbard.

"Come into this room, young man," he said to the apprentice, "and let your companion remain outside with Chowles. Fear nothing. I intend you no injury."

"I do not distrust you," replied Leonard, "and if I did, should have no apprehension." And motioning Rainbird to remain where he was, he entered the room with the knight, who instantly closed the door.

Parravicin's first proceeding was to question him as to his reasons for supposing Nizza to be Thirlby's daughter, and clearly perceiving the deep interest his interrogator took in the matter, and the favourable change that, from some unknown cause, had been wrought in his sentiments, the apprentice did not think fit to hide anything from him. Parravicin's agitation increased as he listened to the recital; and at last, overcome by emotion, he sank into a chair, and covered his face with his hands. Recovering himself in a short time, he arose, and began to pace the chamber to and fro.

"What I have told you seems to have disturbed you, Sir Paul," remarked Leonard. "May I ask the cause of your agitation?"

"No, man, you may not," replied Parravicin, angrily. And then suddenly checking himself, he added, with forced calmness, "And so you parted with Mr. Thirlby on London Bridge, and you think he will return to Doctor Hodges's residence in Watling-street."

"I am sure of it," replied Leonard.

"I must see him without delay," rejoined Parravicin.

"I will take you to him," remarked Leonard; "but first I must see Nizza."

Parravicin walked to a table, on which stood a small silver bell, and ringing it, the summons was immediately answered by an old woman. He was about to deliver a message to her, when the disturbed expression of her countenance struck him, and he hastily inquired the cause of it.

"You must not see the young lady to-night, Sir Paul," said the old woman.

"Why not?" demanded the knight, hastily. "Why not?"

"Because -- but you frighten me so that I dare not speak," was the answer.

"I will frighten you still more if you keep me in this state of suspense," rejoined Parravicin, furiously. "Is she ill?"

"I fear she has got the plague," returned the old woman. "Now you can see her if you think proper."

""I" will see her," said Leonard. "I have no fear of infection."

The old woman looked hard at Parravicin, as if awaiting his orders. "Yes, yes, you can take him to her room," said the knight, who seemed completely overpowered by the intelligence, "if he chooses to go thither. But why do you suppose it is the plague?"

"One cannot well be deceived in a seizure of that kind," replied the old woman, shaking her head.

"I thought the disorder never attacked the same person twice," said Parravicin.

"I myself am an instance to the contrary," replied Leonard.

"And, as you have twice recovered, there may be a chance for Nizza," said Parravicin. "This old woman will take you to her. I will hasten to Doctor Hodges's residence, and if I should fail in meeting him, will not rest till I procure assistance elsewhere. Do not leave her till I return."

Leonard readily gave a promise to the desired effect, and accompanying him to the door, told Rainbird what had happened. The latter agreed to wait below to render any assistance that might be required, and went downstairs with Parravicin and Chowles. The two latter instantly quitted the house together, and hastened to Watling-street.

With a beating heart, Leonard then followed the old woman to Nizza's chamber. They had to pass through a small anteroom, the door of which was carefully locked. The suite of apartments occupied by the captive girl were exquisitely and luxuriously furnished, and formed a striking contrast to the rest of the house. The air was loaded with perfumes; choice pictures adorned the walls; and the tables were covered with books and china ornaments. The windows, however, were strictly barred, and every precaution appeared to be taken to prevent an attempt at escape. Leonard cast an anxious look round as he entered the anteroom, and its luxurious air filled him with anxiety. His conductress, however, did not allow him time for reflection, but led him into another room, still more richly furnished than the first, and lighted by a large coloured lamp, that shed a warm glow around it. An old dwarfed African, in a fantastic dress, and with a large scimetar stuck in his girdle, stepped forward on their approach, and shook his head significantly.
