Occasionally Agahr would thrust his head through the curtains draping the entrance, as if seeking to know that all was well; but the Persian merely gave him a reassuring nod and motioned him away.

This summary banishment did not please the vizier. His daughter had assisted him in forming several plans of great political import, and the conduct of the foreign physician prevented their being carried to a successful issue.

Thus Agahr, appearing again at the entrance, beckoned with imperative gesture the Persian to join him; and, after a careful inspection of his patient, lying peaceful and unconscious, the physician obeyed.

Together they paced up and down the deserted marble passage, the Persian’s quick eye never leaving the entrance to the khan’s chamber, while Agahr plied him with eager questions concerning his master’s condition.

“He will live until his son, the Prince Ahmed, arrives,” said the other, calmly. “He will remain unconscious, but he will live.”

“And then?” asked the vizier, anxiously.

“Then I will awaken him. He will have full command of all his faculties for a brief period—and then he will pass away quickly.”

Agahr sighed.

“Is it not possible for him to pass away during this stupor?” he enquired.

“Yes, it is possible,” answered the Persian. “But I believe I can prevent that. My task requires constant vigilance: that is why I dare not leave the Khan’s chamber.”
