'The lions are loosed on thee'-- so the voice said to me in the night.

Hark! dost thou not hear them--the lions, Harrik's lions, got out of the uttermost desert ?" David could hear the distant roar, for the menagerie was even part of the palace itself.
"Go in peace," continued Harrik soberly and with dignity, "and when Egypt is given to the infidel and Muslims are their slaves, remember that Harrik would have saved it for his Lord Mahomet, the Prophet of God." He clapped his hands, and fifty slaves slid from behind the velvet curtains.
"I have thy word by the tomb of thy mother that thou wilt take the Nubians hence, and leave me in peace ?" he asked.
David raised a hand above his head.

"As I have trusted thee, trust thou me, Harrik, son of Mahomet." Harrik made a gesture of dismissal, and David salaamed and turned to go.

As the curtains parted for his exit, he faced Harrik again.
