It does not seem likely, since it is still broad daylight, and the hour at which the Ebba was timed to arrive.

All the sailors are drawn up on deck, awaiting orders, and Boatswain Effrondat is making preparations to anchor.

Ere a couple of hours have passed I shall know all about it. It will be the first answer to one of the many questions that have perplexed me since the schooner put to sea.

And yet it is most unlikely that the port to which the Ebba belongs is situated on one of the Bermuda islands, in the middle of an English archipelago—unless the Count d’Artigas has kidnapped Thomas Roch for the British government, which I cannot believe.

I become aware that this extraordinary man is gazing at me with singular persistence. Although he can have no suspicion that I am Simon Hart, the engineer, he must be asking himself what I think of this adventure. If Warder Gaydon is but a poor devil, this poor devil will manifest as much unconcern as to what is in store for him as any gentleman could—even though he were the proprietor of this queer pleasure yacht. Still I am a little uneasy under his gaze.

I dare say that if the Count d’Artigas could guess how certain things have suddenly become clear to me, he would not hesitate to have me thrown overboard.

Prudence therefore commands me to be more circumspect than ever.

Without giving rise to any suspicion—even in the mind of Engineer Serko—I have succeeded in raising a corner of the mysterious veil, and I begin to see ahead a bit.

As the Ebba draws nearer, the island, or rather islet, towards which she is speeding shows more sharply against the blue background of the sky. The sun which has passed the zenith, shines full upon the western side. The islet is isolated, or at any rate I cannot see any others of the group to which it belongs, either to north or south.

This islet, of curious contexture, resembles as near as possible a cup turned upside down, from which a fuliginous vapor arises. Its summit—the bottom of the cup, if you like—is about three hundred feet above the level of the sea, and its flanks, which are steep and regular, are as bare as the sea-washed rocks at its base.
