“Pardon my stupid pleasantry, Mr. Greig,” he said, reddening slightly. “I have been so long one of his Majesty's Ministers, and of late have seen so many urgent couriers from France with prime news to be bargained for, that I have grown something of a cynic. You are the first that has come with a secret not for sale. Believe me, your story will have all the more attention because it is offered disinterestedly.”

In twenty minutes I had put him into possession of all I knew of the plans for invasion. He walked up and down the room, with his hands behind his back, intently listening, now and then uttering an exclamation incredulous or astonished.

“You are sure of all this?” he asked at last sharply, looking in my face with embarrassing scrutiny.

“As sure as any mortal man may be with the gift of all his senses,” I replied firmly. “At this moment Thurot's vessel is, I doubt not, taking in her stores; the embarkation of troops is being practised daily, troops are assembled all along the coast from Brest to Vannes, and—”

“Oh! on these points we are, naturally, not wholly dark,” said the Minister. “We have known for a year of this somewhat theatrical display on the part of the French, but the lines of the threatened invasion are not such as your remarkable narrative suggests. You have been good enough to honour me with your confidence, Mr. Greig; let me reciprocate by telling you that we have our—our good friends in France, and that for six months back I have been in possession of the Chevalier D'Arcy's instructions to Dumont to reconnoitre the English coast, and of Dumont's report, with the chart of the harbours and towns where he proposed that the descent should be made.” He smiled somewhat grimly. “The gentleman who gave us the information,” he went on, “stipulated for twenty thousand pounds and a pension of two thousand a year as the just reward for his loving service to his country in her hour of peril. He was not to get his twenty thousand, I need scarcely say, but he was to get something in the event of his intelligence proving to be accurate, and if it were for no more than to get the better of such a dubious patriot I should wish his tale wholly disproved, though we have hitherto acted on the assumption that it might be trustworthy. There cannot be alternative plans of invasion; our informant—another Scotsman, I may say—is either lying or has merely the plan of a feint.”

“You are most kind, sir,” said I.

“Oh,” he said, “I take your story first, and as probably the most correct, simply because it comes from one that loves his country and makes no bagman's bargains for the sale of secrets vital to her existence.”

“I am much honoured, sir,” said I, with a bow.

And then he stopped his walk abruptly and faced me again.

“You have told me, Mr. Greig,” he went on, “that Conflans is to descend in a week or two on the coast of Scotland, and that Thurot is to create a diversion elsewhere with the aid of the Swedes, I have, from the most delicate considerations, refrained from asking you how you know all this?”
