The unaccountable loss of so many vessels in the Atlantic during the past few years is attributable to him. He had merely changed the scene of his exploits. It was supposed that he had been got rid of, whereas he is continuing his piratical practices in the most frequented ocean on the globe, by means of the tug which is believed to be lying at the bottom of Charleston Bay.
"Now," I say to myself, "I know his real name and that of his lair--Ker Karraje and Back Cup;" and I surmise that if Engineer Serko has let me into the secret he must have been authorized to do so. Am I not meant to understand from this that I must give up all hope of ever recovering my liberty?
Engineer Serko had manifestly remarked the impression created upon me by this revelation. I remember that on leaving me he went towards Ker Karraje's habitation, no doubt with the intention of apprising him of what had passed.
After a rather long walk around the lagoon I am about to return to my cell, when I hear footsteps behind me. I turn and find myself face to face with the Count d'Artigas, who is accompanied by Captain Spade. He glances at me sharply, and in a burst of irritation that I cannot suppress, I exclaim:
"You are keeping me here, sir, against all right. If it was to wait upon Thomas Roch that you carried me off from Healthful House, I refuse to attend to him, and insist upon being sent back."
The pirate chief makes a gesture, but does not reply.
Then my temper gets the better of me altogether.
"Answer me, Count d'Artigas--or rather, for I know who you are--answer me, Ker Karraje!" I shout.
"The Count d'Artigas is Ker Karraje," he coolly replies, "just as Warder Gaydon is Engineer Simon Hart; and Ker Karraje will never restore to liberty Engineer Simon Hart, who knows his secrets."
FIVE WEEKS IN BACK CUP.
The situation is plain. Ker Karraje knows who I am. He knew who I was when he kidnapped Thomas Roch and his attendant.
How did this man manage to find out what I was able to keep from the staff of Healthful House? How comes it that he knew that a French engineer was performing the duties of attendant to Thomas Roch? I do not know how he discovered it, but the fact remains that he did.
Evidently he had means of information which must have been costly, but from which he has derived considerable profit. Besides, men of his kidney do not count the cost when they wish to attain an end they have in view.
Henceforward Ker Karraje, or rather Engineer Serko, will replace me as attendant upon Thomas Roch. Will he succeed better than I did? God grant that he may not, that the civilized world may be spared such a misfortune!
I did not reply to Ker Karraje's Parthian shot, for I was stricken dumb. I did not, however, collapse, as the alleged Count d'Artigas perhaps expected I would.
No! I looked him straight in the eyes, which glittered angrily, and crossed my arms defiantly, as he had done. And yet he held my life in his hands! At a sign a bullet would have laid me dead at his feet. Then my body, cast into the lagoon, would have been borne out to sea through the tunnel and there would have been an end of me.
After this scene I am left at liberty, just as before. No measure is taken against me, I can walk among the pillars to the very end of the cavern, which--it is only too clear--possesses no other issue except the tunnel.
When I return to my cell, at the extremity of the Beehive, a prey to a thousand thoughts suggested by my situation, I say to myself:
"If Ker Karraje knows I am Simon Hart, the engineer, he must at any rate never know that I am aware of the position of Back Cup Island."
As to the plan of confiding Thomas Roch to my care, I do not think he ever seriously entertained it, seeing that my identity had been revealed to him. I regret this, inasmuch as the inventor will indubitably be the object of pressing solicitations, and as Engineer Serko will employ every means in his power to obtain the composition of the explosive and deflagrator, of which he will make such detestable use during future piratical exploits.
