What effect this news has upon me, and what emotion it awakens² within my soul! The end, I feel, is at hand. May it be such as civilization and humanity are entitled to.  
Up to the present I have indited³ my notes day by day. Henceforward it is imperative⁴ that I should inscribe⁵ them hour by hour, minute by minute. Who knows but what Thomas Roch’s last secret may be revealed to me and that I shall have time to commit it to paper! Should I die during the attack God grant that the account of the five months I have passed in Back Cup may be found upon my body!
 
At first Ker Karraje, Engineer Serko, Captain Spade, and several of their companions took up position on the exterior⁶ base of the island. What would I not give to be able follow to them, and in the friendly shelter of a rook watch the on-coming warships⁷!
 
An hour later they return after having left a score of men to keep watch. As the days at this season of the year are very short there is nothing to fear before the morrow. It is not likely that the ships will attempt a night attack and land a storming party, for they must imagine that the place is in a thorough condition of defence.
 
All night long the pirates work, installing the trestles at different points of the coast. Six have been taken through the passage to places selected in advance.
 
This done, Engineer Serko joins Thomas Roch in his laboratory. Is he going to tell him what is passing, that a squadron is in view of Back Cup, and that his fulgurator will be employed to defend the island?
 
What is certain is that half a hundred engines, each charged with several pounds of the explosive and of the substance that ensures a trajectory⁹ superior to that of any other projectile¹⁰, are ready for their work of destruction.
 
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 reigns¹¹ in the cavern¹².
 
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 vessels¹³ 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 avenging¹⁴ 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 ascertain¹⁵. 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 Lieutenant¹⁶ 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 annihilate¹⁷ 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 warship⁸ are powerless against them, they think neither of the difficulties nor menaces held out by the future.
 
I surmise¹⁸ that the trestles have been set up on the northwest coast with the grooves¹⁹ 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 deserted²⁰, but the entrance to the passage is kept by Count d’Artigas’ Malay. I saunter, without any fixed²¹ 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 apprise²² him of its proximity²³, not till he brusquely points out to him the vengeance²⁴ he can accomplish.
 
Then I conceive the idea of enlightening Thomas Roch, myself, of the responsibility he is incurring²⁵ and of revealing to him in this supreme²⁶ hour the character of the men who want him to co-operate in their criminal projects.
 
Yes, I will, attempt it, and may I succeed in fanning into a flame any spark of patriotism²⁷ that may still linger in his rebellious²⁸ soul!
 
Roch is shut up in his laboratory. He must be alone, for never does he allow any one to enter while he is preparing his deflagrator.
 
As I pass the jetty I notice that the tug²⁹ is moored³⁰ in its accustomed place. Here I judge it prudent³¹ to walk behind the first row of pillars and approach the laboratory laterally—which will enable me to see whether anybody is with him. When I have gone a short distance along the sombre avenue I see a bright light on the opposite side of the lagoon³². It is the electric light in Roch’s laboratory as seen through a narrow window in the front.
 
Except in that particular spot, the southern shore of the lake is in darkness, whereas, in the opposite direction, the Beehive is lit up to its extremity³³ at the northern wall. Through the opening in the dome³⁴, over the lake I can see the stars shining. The sky is clear, the tempest has abated³⁵, and the squalls no longer penetrate³⁶ to the interior of Back Cup.
 
When near the laboratory, I creep along the wall and peep in at the window.
 
Thomas Roch is there alone. The light shines full on his face. If it is somewhat drawn³⁷, and the lines on the forehead are more pronounced, his physiognomy, at least, denotes perfect calmness and self-possession. No, he is no longer the inmate³⁸ of Pavilion No. 17, the madman of Healthful House, and I ask myself whether he is not radically³⁹ cured, whether there is no further danger of his reason collapsing⁴⁰ in a final paroxysm.
 
He has just laid two glass phials upon the table, and holds a third in his hand. He holds it up to the light, and observes the limpidity⁴¹ of the liquid it contains.
 
I have half a mind to rush in, seize the tubes and smash them, but I reflect that he would have time to make some more of the stuff. Better stick to my first plan.
 
I push the door open and enter.
 
“Thomas Roch!” I exclaim.
 
He has not heard, nor has he seen me.
 
“Thomas Roch!” I repeat.
 
He raises his head, turns and gazes at me.
 
“Ah! it is you, Simon Hart!” he replies calmly, even indifferently.
 
He knows my name. Engineer Serko must have informed him that it was Simon Hart, and not Keeper Gaydon who was watching over him at Healthful House.
 
“You know who I am?” I say.
 
“Yes, as I know what your object was in undertaking⁴² such a position. You lived in hopes of surprising a secret that they would not pay for at its just value!”
 
Thomas Roch knows everything, and perhaps it is just as well, in view of what I am going to say.
 
“Well, you did not succeed, Simon Hart, and as far as this is concerned,” he added, flourishing the phial, “no one else has succeeded, or ever will succeed.”
 
As I conjectured⁴³, he has not, then, made known the composition of his deflagrator.
 
Looking him straight in the face, I reply:
 
“You know who I am, Thomas Roch, but do you know in whose place you are?”
 
“In my own place!” he cries.
 
That is what Ker Karraje has permitted him to believe. The inventor thinks he is at home in Back Cup, that the riches accumulated in this cavern are his, and that if an attack is made upon the place, it will be with the object o............
