But the one matter uppermost in my mind was the alleged plot by the Powers against England. As I had given the Princess my word of honour not to mention it to a soul, I was unable to consult Lord Barmouth, and was compelled to wait and watch for signs that the conspiracy was in progress.

Those days were full of fevered anxiety. His Excellency was absent in the country, and the duties of the Embassy devolved upon myself. The facts that the German Ambassador had travelled suddenly to Berlin to consult the Minister of Foreign Affairs, and that urgent despatches were being exchanged daily between the Austrian Embassy and Vienna, seemed to me to establish the truth of Léonie’s statement. I met my friends Volkouski and Korniloff, the Russian attachés, in the Grand Café one evening, and we spent an hour together over our consommation down at the Alcazar, in the Champs Elysées; but they apparently knew nothing, or, if they did, naturally hesitated to expose their secret. Hither and thither I sought for evidence, and with my suspicions aroused found confirmation of the Princess’s story in every diplomatic action. The German Emperor made a speech in Berlin in which, with many references to his grandfather and the Fatherland, he assured Europe that never in recent history had peace been so firmly established among nations; and both from Rome and St. Petersburg came news of unusual inactivity. That calm foreboded a storm.

As those hot, anxious days went slowly past I strove to form some theory as to the manner in which the conspiracy had been arranged and as to the persons chiefly responsible, but could find none.

Had not Léonie plainly told me that this dastardly plot among jealous nations aimed directly at the undermining of the British power, the ruin of England’s prestige, and the destruction of her supremacy on the sea? I, as a diplomatist, knew too well the vulnerability of our Empire. We have patriotism, it is true, for the sons of England will ever shed the last drop of their blood in the defence of their beloved country; but something more than patriotism is now necessary for successful defence. In these days, when Europe is daily arming and small republics, backed by certain of the Powers, amuse themselves by twisting the Lion’s tail, an efficient British army is necessary, as well as a navy that must be stronger than that of the rest of the world. We at the embassies know how, by descending to methods which we as Englishmen scorn to use, our enemies are often able to outwit and checkmate us; and we know also that in England foreign spies are allowed to come and go at will, and that the interesting gentlemen whom we welcome are gradually elaborating their plans for the invasion of our shores.

Many there are who laugh at the idea of an invasion of England, but every diplomatist in Europe knows well that the problem is discussed in every military centre on the Continent, and that in certain quarters strategists have drawn up plans by which the catastrophe can undoubtedly be accomplished. Therefore, in spite of the sneers of those who rest upon a false belief in their insular security, we should be in a condition not only to defend, but to defy—a condition which, to our sorrow, does not at present exist.

The Princess had offered me such information as would enable me to crush the conspiracy against us, and I had refused her terms. Sometimes, as I sat alone in my room thinking, I felt that I had made a mistake, and that I ought, in the interests of my country, to have accepted. Then, at others, I felt glad that I had had the courage to refuse her conditions, and to leave her as I had done. As she had learned the truth from the Emperor Francis Joseph of Austria, the secret must be known in the Court circle at Vienna.

Yet unfortunately it was impossible for me to go there, and equally impossible, after giving my word of honour to Léonie, to explain my fears to Kaye and allow the secret service to make inquiries. I knew from many signs that catastrophe was imminent, but was utterly powerless to avert it.

Reader, place yourself for a single moment in my position—your own honour at stake on the one hand, and that of your country on the other. It seemed base to speak, base to keep silence.

I shall not easily forget what I suffered during this period of anxious inactivity. The weeks went by, Lord Barmouth came back sun-tanned and jovial, and all the other representatives of the European Courts returned one by one after their summer leave. Parisians, driven away by wet weather, deserted the plages, the châteaux, and the various inland watering-places; and from Dieppe and Trouville, Arcachon and Luchon, Vichy and Aix, Royat and Contrexéville the crowds of mothers and daughters, with a sprinkling of fathers, came gaily back to their favourite boulevards, their favourite magasins, and their favourite cafés. Paris was herself again—for the winds were cold, the leaves in the boulevards were falling in showers, and the wet pavements were rendered disagreeable on account of them.

One afternoon towards the end of November I entered my little flat with my latchkey, and walked straight into my sitting-room, when, to my surprise, a beautiful girl rose from the chair in which she had been sitting, and, without speaking a word, held out her hand.
