Raoul now remembered that his brother had once shown him that mysterious person, of whom nothing was known except that he was a Persian and that he lived in a little old-fashioned flat in the Rue de Rivoli.

The man with the ebony skin, the eyes of jade and the astrakhan cap bent over Raoul.

“I hope, M. de Chagny,” he said, “that you have not betrayed Erik’s secret?”

“And why should I hesitate to betray that monster, sir?” Raoul rejoined haughtily, trying to shake off the intruder. “Is he your friend, by any chance?”

“I hope that you said nothing about Erik, sir, because Erik’s secret is also Christine Daae’s and to talk about one is to talk about the other!”

“Oh, sir,” said Raoul, becoming more and more impatient, “you seem to know about many things that interest me; and yet I have no time to listen to you!”

“Once more, M. de Chagny, where are you going so fast?”

“Can not you guess? To Christine Daae’s assistance . . . ”

“Then, sir, stay here, for Christine Daae is here!”

“With Erik?”

“With Erik.”

“How do you know?”

“I was at the performance and no one in the world but Erik could contrive an abduction like that! . . . Oh,” he said, with a deep sigh, “I recognized the monster’s touch! . . . ”

“You know him then?”

The Persian did not reply, but heaved a fresh sigh.

“Sir,” said Raoul, “I do not know what your intentions are, but can you do anything to help me? I mean, to help Christine Daae?”

“I think so, M. de Chagny, and that is why I spoke to you.”

“What can you do?”

“Try to take you to her . . . and to him.”

“If you can do me that service, sir, my life is yours! . . . One word more: the commissary of police tells me that Christine Daae has been carried off by my brother, Count Philippe.”

“Oh, M. de Chagny, I don’t believe a word of it.”

“It’s not possible, is it?”

“I don’t know if it is possible or not; but there are ways and ways of carrying people off; and M. le Comte Philippe has never, as far as I know, had anything to do with witchcraft.”

“Your arguments are convincing, sir, and I am a fool! . . . Oh, let us make haste! I place myself entirely in your hands! . . . How should I not believe you, when you are the only one to believe me . . . when you are the only one not to smile when Erik’s name is mentioned?”

And the young man impetuously seized the Persian’s hands. They were ice-cold.

“Silence!” said the Persian, stopping and listening to the distant sounds of the theater. “We must not mention that name here. Let us say ‘he’ and ‘him;’ then there will be less danger of attracting his attention.”

“Do you think he is near us?”

“It is quite possible, Sir, if he is not, at this moment, with his victim, IN THE HOUSE ON THE LAKE.”

“Ah, so you know that house too?”

“If he is not there, he may be here, in this wall, in this floor, in this ceiling! . . . Come!”

And the Persian, asking Raoul to deaden the sound of his footsteps, led him down passages which Raoul had never seen before, even at the time when Christine used to take him for walks through that labyrinth.

“If only Darius has come!” said the Persian.

“Who is Darius?”

“Darius? My servant.”

They were now in the center of a real deserted square, an immense apartment ill-lit by a small lamp. The Persian stopped Raoul and, in the softest of whispers, asked:

“What did you say to the commissary?”

“I said that Christine Daae’s abductor was the Angel of Music, ALIAS the Opera ghost, and that the real name was . . . ”

“Hush! . . . And did he believe you?”

“No.”

“He attached no importance to what you said?”

“No.”

“He took you for a bit of a madman?”

“Yes.”

“So much the better!” sighed the Persian.

And they continued their road. After going up and down several staircases which Raoul had never seen before, the two men found themselves in front of a door which the Persian opened with a master-key. The Persian and Raoul were both, of course, in dress-clothes; but, whereas Raoul had a tall hat, the Persian wore the astrakhan cap which I have already mentioned. It was an infringement of the rule which insists upon the tall hat behind the scenes; but in France foreigners are allowed every license: the Englishman his traveling-cap, the Persian his cap of astrakhan.

“Sir,” said the Persian, “your tall hat will be in your way: you would do well to leave it in the dressing-room.”

“What dressing-room?” asked Raoul.

“Christine Daae’s.”

And the Persian, letting Raoul through the door which he had just opened, showed him the actress’ room opposite. They were at the end of the passage the whole length of which Raoul had been accustomed to traverse before knocking at Christine’s door.

“How well you know the Opera, sir!”

“Not so well as ‘he’ does!” said the Persian modestly.

And he pushed the young man into Christine’s dressing-room, which was as Raoul had left it a few minutes earlier.

Closing the door, the Persian went to a very thin partition that separated the dressing-room from a big lumber-room next to it. He listened and then coughed loudly.

There was a sound of some one stirring in the lumber-room; and, a few seconds later, a finger tapped at the door.

“Come in,” said th............
