“Come in,” said the Persian.

A man entered, also wearing an astrakhan cap and dressed in a long overcoat. He bowed and took a richly carved case from under his coat, put it on the dressing-table, bowed once again and went to the door.

“Did no one see you come in, Darius?”

“No, master.”

“Let no one see you go out.”

The servant glanced down the passage and swiftly disappeared.

The Persian opened the case. It contained a pair of long pistols.

“When Christine Daaé was carried off, sir, I sent word to my servant to bring me these pistols. I have had them a long time and they can be relied upon.”

“Do you mean to fight a duel?” asked the young man.
