Abbot groaned.

Hakin continued hurriedly: "So Dolf plans to leave at once. He is already rounding up his followers. Come on! We must get out ahead of him!"

The water rose above their bow windows, but suddenly and inexplicably it began to subside again. A man waded by around the bow of Abbot's machine.
