In a word, everything pointed to universal war. Only the United States preserved an inscrutable silence, which had been broken only by four words: "Hands off our commerce." And to these the Leagued Nations had listened, if rather by compulsion than respect.
Who was he, then, that he should, as it were, sound the trump of approaching doom in the ears of a world round which from east to west and from west again to east the battledrums might any day be sounding and the roar of artillery thundering its answering echo.
But a somewhat different aspect was given to these reflections by a letter which he found waiting for him in the library at Whernside House. It ran thus:
"Sir,—You will not, I suppose, have forgotten a certain incident which happened towards the end of June 1907 in the Bay of Clifden, Connemara. You won that little swimming race by a yard or so, and since then it appears to me that, although you may not be aware of it, you and I have been running a race of a very different sort, although possibly for the same prize.
"You will understand what prize I mean, and by this time you ought to know that I have the power of taking it by force, if I cannot win it in the ordinary way of sport or battle. I am in command of the only really irresistible force in the world. I created that force, and, by doing so, made the invasion of England and the present war possible. I have done so because I hate England, and desire to release my own country from her tyranny and oppression; but I can love as well as I can hate, and whether you understood it or not, I, who had never loved a woman before, loved Auriole Parmenter from the moment that you and I lifted her out of the water, and she smiled on us, and thanked us for saving her life.
"Before we parted that day I could see love in your eyes when you looked at her, if you could not see it in mine. You are her father's private astronomer, and until lately you have lived in almost daily intercourse with her, in which, of course, you have had a great advantage over myself, who have not from that time till now been blessed by even the sight of her.
"But during that time it seems that you have discovered a comet, which is to run into the earth and destroy all human life, unless you prevent it. I know this because I know of the challenge you gave to the German Emperor in Canterbury. I know also of what you have been doing in Bolton. You are turning a coal pit into a cannon, with which you believe that you can blow this comet into thin air or gas before it meets the earth, and you threatened His Majesty that if the war was not stopped the human race should be destroyed.
"That, if you will pardon the expression, was a piece of bluff. You love Miss Parmenter perhaps as much as, though not possibly more than, I do, and therefore you would certainly not destroy the world as long as she was alive in it. You would be more or less than man if you did, and I don't believe you are either, and therefore I think you will understand the proposition I am going to make to you.
"Granted hypothesis that the world will come to an end by means of this comet on a certain day, and granted also that you are able to save it with this cannon of yours, I write now to tell you that, whether the war stops or not in obedience to your threat, I will not allow you to save the world unless Miss Parmenter consents to marry me within two months from now. If she does, the war shall stop, or at anyrate I will allow the British forces to conquer the whole of Europe on the sole condition of giving independence to Ireland. They cannot win without my fleet of Flying Fishes, and if I turn that fleet against them they will not only be defeated but annihilated. In other words, with the sole exception of my own country, I offer England the conquest of Europe in exchange for the hand of one woman.
"In the other alternative, that is to say, if Miss Parmenter, her father and yourself do not consent to this proposal, I will not allow you to save the world. I can destroy your cannon works at Bolton as easily as I destroyed the forts at Portsmouth and Dover, and as easily as I can and will kill you, and wreck your observatory. When I have done this I will take possession of Miss Parmenter by force, and then your comet can come along and destroy the world as soon as it likes.
"I shall expect a definite answer to this letter, signed by Mr Parmenter and yourself, within seven days. If you address your letter to Mr James Summers, 28a Carlos Street, Sheerness, it will reach me; but I must warn you that any attempt to discover why it will reach me from that address will be punished by the bombardment and destruction of the town.
"I hope you will see the reasonableness and moderation of my conditions, and remain, yours faithfully,
"John Castellan."
CHAPTER XXXII
A VIGIL IN THE NIGHT
Although Lennard had always recognised the possibility of such a catastrophe as that which John Castellan threatened, and had even taken such precautions as he could to prevent it, still this direct menace, coming straight from the man himself, brought the danger home to him in a peculiarly personal way.
The look which had passed between them as they were swimming their race in Clifden Bay had just as much meaning for him as for the man who now not openly professed himself his rival, but who threatened to proceed to the last extremities in order to gain possession of the girl they both loved. It was impossible for him not to believe that the man who had been capable of such cold-blooded atrocities as he had perpetrated at Portsmouth, London and other places, would hesitate for a moment in carrying out such a threat, and if he did—No, the alternative was quite too horrible to think of yet.
