"To shore! To horse!" cried the raging monarch.

A quarter of an hour later, horsemen were clattering down the stony street along the water front of Marmora, pausing now and then to stare out into the sea mist, dashing on, stopping and staring, and on again. The foremost to reach the Castle of the Seven Towers left orders to scour the shore, and to set patrol to prevent any one landing. Some were ordered to dart across to the islands.
