They left the tent in silence. The captain of the guard accompanied them to the boat.

"Azemilcus is betraying his city," Chares whispered.

"We shall save Artemisia and rescue Thais," Clearchus replied, gripping the arm of his friend.

They entered the boat and rowed silently to the Egyptian Harbor. The towering height of the wall swallowed the little craft in its shadow and no sentinel challenged them. They bent their heads as they glided under the great guard-chains that stretched across the entrance of the harbor, and threading their way among the shipping, they reached the landing and disembarked.

Keeping to the left, the chancellor led them toward the palace. More than once they were forced to step aside to avoid the heaps of ruins that told of the work done by the ballistæ. As they advanced, the great bulk of the palace rose before them above the wall, to which it was joined and of which it formed a part. As they advanced, the chancellor was careful to keep in the deepest shadow, and his hand shook as he fitted the key into a small door in the palace wall.

"We are safe!" he said to the prince as the door closed behind them.

"Very well," the young man replied, yawning; "I am going to bed."

He turned abruptly into a lateral passage and disappeared. The chancellor seemed in doubt for a moment whether to call him back, but he decided to let him go.

"Follow me," he said to the Macedonians.

They groped their way upward after him along a winding stair that seemed to be built into the city wall. This slow progress continued for many minutes without a glimmer of light until they reached what appeared to be a windowless chamber. There the chancellor left them, bidding them wait until he had notified the king of their arrival.
