As to the deflagrator liquid, Thomas Roch has a certain number of phials of it, and—I know only too well—will not refuse to help Ker Karraje’s pirates with it.

During these preparations night has come on. Only the lamps of the Beehive are lighted and a semi-obscurity reigns in the cavern.

I return to my cell. It is to my interest to keep out of the way as much as possible, for Engineer Serko’s suspicions might be revived now that the squadron is approaching Back Cup.

But will the vessels sighted continue on their course in this direction? May they not be merely passing on their way to Bermuda? For an instant this doubt enters my mind. No, no, it cannot be! Besides, I have just heard Captain Spade declare that they are lying to in view of the island.

To what nation do they belong? Have the English, desirous of avenging the destruction of the Sword, alone undertaken the expedition? May not cruisers of other nations be with them? I know not, and it is impossible to ascertain. And what does it matter, after all, so long as this haunt is destroyed, even though I should perish in the ruins like the heroic Lieutenant Davon and his brave crew?

Preparations for defence continue with coolness and method under Engineer Serko’s superintendence. These pirates are obviously certain that they will be able to annihilate their assailants as soon as the latter enter the dangerous zone. Their confidence in Roch’s fulgurator is absolute. Absorbed by the idea that these warship are powerless against them, they think neither of the difficulties nor menaces held out by the future.

I surmise that the trestles have been set up on the northwest coast with the grooves turned to send the engines to the north, west, and south. On the east, as already stated, the island is defended by the chain of reefs that stretches away to the Bermudas.

About nine o’clock I venture out of my cell. They will pay little attention to me, and perhaps I may escape notice in the obscurity. Ah! if I could get through that passage and hide behind some rock, so that I could witness what goes on at daybreak! And why should I not succeed now that Ker Karraje, Engineer Serko, Captain Spade, and the pirates have taken their posts outside?

The shores of the lake are deserted, but the entrance to the passage is kept by Count d’Artigas’ Malay. I saunter, without any fixed idea, towards Thomas Roch’s laboratory. This reminds me of my compatriot. I am, on reflection, disposed to think that he knows nothing about the presence of a squadron off Back Cup. Probably not until the last moment will Engineer Serko apprise him of its proximity, not till he brusquely points out to him the vengeance he can accomplish.

Then I conceive the idea of enlightening Thomas Roch, myself, of the responsibility he is incurring and of revealing to him in this supreme hour the character of the men who want him to co-operate in their criminal projects.
