So the boy walked up and down the room, whilst the girls told each other stories in order to keep awake--so anxious were they to hear the first news of the defeat of the rebels.

Carlo rushed to the door and seized the faithful Indian's hand.

'What is it, Andreas? Speak quickly.'

'There must be some treachery, Señor, for a party of pirates are climbing up towards the castle, and the guards below have disappeared from the walls.'
