"Sebastian," said Theodora, presenting Harkaway to her foster-sister and the latter's lover, "this is Mr. Harkaway."

The Greek official bowed with an air of constraint.

"Theodora has told you all, sir?"

"Yes, you have risked much to save my boys' lives."

"Since I can count upon your forbearance," said Sebastian, "I will say no more. Follow me to the presence of the boys."

So saying, Sebastian led the way through the stone-paved passages to the tower overhanging the sea, in which the cell of the two boys was situated.

At the base of the tower were jagged, sea-beaten rocks.

Beside the tower, at about half the height of the tower, reckoning from the level of the sea, was a gravel terrace, covered with a waterproof canopy, so as to form a sort of shed.

And looking out of the tower windows as they passed up its steep inner staircase, Harkaway inquired what this place was.

"That is used as the prison mortuary."
