"I have another waiting at the end of the southern quay," replied Oleric. "Urk knows the harbor as he knows the palm of his hand. Once through the outer channel, then down the coast to Ruthar."

They left the marizel moored in the canal and went up through a passage in the rock to where a door led into the great arched tunnel above, where Chedar's Flight ended at the harbor of Adlaz town. Now there was only the crossing of the wharf and all would be well.

But hark! As Oleric laid his hand on the door of the passage, came the thunder of hoofs through the tunnel, and a steel rider on a white horse flashed past and clattered across the court to the warehouses. He rode furiously, and as he neared the quays he cried out.

Oleric tore the door open.

"Our work behind there is overtaking us!" he cried. "We must run for it!"

Polaris shifted Mordo's weight from his shoulder to his arms and bounded across the pavement at the heels of the captain. Behind came Wright, Everson, and Oleric's Rutharian henchman. Rombar leaped at the side of Polaris.

Lights flashed ahead of them as they ran. When they neared the south quay, they saw that the way to it was barred by a thin line of men in steel, among whom glittered the golden armor of the captain of the canal guard.

Casting a glance over his shoulder as he ran, to note the disposal of his own party, Oleric drew his sword and charged the line. The guard captain leaped out to meet him, shield up and sword aloft. Him Oleric cut down with a single stroke, laughing as he struck. In another instant Everson's blade was out and busy. His cutlass exercises at old Annapolis stood him well. The line of steel gave. The other three fugitives, running together, dashed through and gained the quay. But behind them came many men.

Polaris laid Mordo on the wharf and looked about him for a weapon. The door of the nearest warehouse was made fast with a bar of bronze or steel, nearly eight feet in length. Janess tore it from its rests. At the end of the quay he saw the marizel of Oleric riding in its moorings, and saw that Urk had clambered aboard it and was making all ready to cast off.

Whirling his ponderous weapon, which was a weight to tax the strength of an ordinary man to lift from the ground, Polaris rushed into the thick of the press, where the red captain and the naval lieutenant fought side by side.
