'Pedro!' she called softly; but no porter answered. Even the Indian slaves were gone. Etta's curiosity was now fairly awakened. It could not be possible that the castle was deserted, and that she and Felipa were forgotten by every one!

'Carlo!' she cried louder, 'Andreas! Pedro!' No answer, and the girl stepped out into the courtyard and walked a little way down to the second gate. Then sounds indeed reached her ears: the clashing of swords, the loud tones of angry voices, the waving of torches, and the shrill whoops of Indians, mingled with many fierce English oaths.

There was no longer any doubt: the enemy, by some means, which of course Etta could not understand, had forced the passage leading over the ditch to the great gate, and were now between that and the inner courtyard, where, as Etta knew, no one remained to defend the gate of the castle itself. Her first impulse was to rush back and fly to some safer place; but so frightened was she that she felt hardly able to move; and at that moment, gazing at the small mass of struggling beings, she saw Carlo at the head of some dozen Indians barring the way before a far larger number of the enemy. This glance showed her also the form of the English lad; so much slighter and so much fairer of face than any about him that she could not mistake him as the torchlight fell on him.

'Carlo! Carlo!' she cried in her agony. No sound came back in answer but the yells and cries of the two parties; and with the instinct of helping her dear Felipa she at last found strength to turn away from the terrible sight and to fly back to the gate and so up the stairs, and as she ran she called out, 'Shut the gates: they are coming! They will soon overpower our people. Quick, make haste! Pedro, where are you?'

And still repeating these words, Etta dashed into the dwelling-room, looking so excited and pale that there was no longer any doubt that the worst had happened, as she exclaimed, 'We are lost! The castle will be taken! What can we do?'

Nor had brave Etta been mistaken. When Andreas had come to fetch Carlo, the faithful Indian had just discovered that the path known only to Don Estevan del Campo and a few of those in authority had been betrayed. Before he could do more than collect the few slaves and soldiers left in the castle, and station them at the entrance to the weakest portion of the wall, fetch Carlo as described, and with the mere handful of men then available make a brave stand, the chief gate of the castle was really taken. Andreas little knew that all his valour was useless; but it was otherwise with Carlo, who, as he threw himself into the mêlée, was conscious that no bravery could really be of any use. Indeed the attack on this side was but a ruse, for another body of men were quietly making their way to the principal gate of Santa Teresa, and were now being let in by one of the Marquis's officers, whom he had easily persuaded that a desperate encounter with these pirates would only result in their all being taken prisoners, and most likely killed.

It was Andreas who suddenly discovered the treachery, and, not understanding the real meaning of the extraordinary events which were taking place, now shouted to those about him that there was yet time to stop the entrance of those rascals.

In this rush Carlo was accidentally thrown down, and in falling his knee struck against a rocky projection, so that for a few seconds he lost consciousness. When he came to himself he tried hard to struggle to his feet, for he beheld at this moment a boy suddenly spring over the wall and come hastily towards him. Carlo heard the confused noise of the assailants and defenders, who had passed on and left him, so that he now found himself alone with a lad of about his own age, whom he had previously seen, and who was doubtless Henry Morgan's son.

Clenching his teeth, and grasping his sword, he tottered to his feet.

'Rascal! infidel! son of a pirate!' cried poor Carlo, not caring what names he bestowed. 'You may kill me, but I will sell my life dearly. You at least shall not come further. Go and tell your father that Carlo del Campo will not be a party to any treachery.'
