pleasant journey.

Dawson did not come out of his berth at Euston until after Hagan had left the station in a taxi-cab, much to Cary's surprise, and then was quite ready, even anxious, to remain for breakfast at the hotel. He explained his strange conduct. "Two of my men," said he, as he wallowed in tea and fried soles—one cannot get Dover soles in the weary North—"who travelled in ordinary compartments, are after Hagan in two taxis, so that if one is delayed, the other will keep touch. Hagan's driver also has had a police warning, so that our spy is in a barbed-wire net. I shall hear before very long all about him."

Cary and Dawson spent the morning at the hotel with a telephone beside them; every few minutes the bell would ring, and a whisper of Hagan's movements steal over the wires into the ears of the spider Dawson. He reported progress to Cary with ever-increasing satisfaction.

"Hagan has applied for and been granted a passport to Holland, and has booked a passage in the boat which leaves Harwich to-night for the Hook. We will go with him. The other two spies, with the copies, haven't turned up yet, but they are all right. My men will see them safe across into Dutch territory, and make sure that no blundering Customs officer interferes with their papers. This time the way of transgressors shall be very soft. As for Hagan, he is not going to arrive."

"I don't quite understand why you carry on so long with him," said
Cary, who, though tired, could not but feel intense interest in the
perfection of the police system and in the serene confidence of
Dawson. The Yard could, it appeared, do unto the spies precisely what
Dawson chose to direct.

"Hagan is an American citizen," explained Dawson. "If he had been a British subject I would have taken him at Euston—we have full evidence of the burglary, and of the stolen papers in his suit-case. But as he is a damned unbenevolent neutral we must prove his intention to sell the papers to Germany. Then we can deal with him by secret court-martial.[1] The journey to Holland will prove this intention. Hagan has been most useful to us in Ireland, and now in the North of England and in Scotland, but he is too enterprising and too daring to be left any longer on the string. I will draw the ends together at the Hook."

[Footnote 1: Author's Note: This conversation is dated May, 1916.]

"I did not want to go to Holland," said Cary to me, when telling his story. "I was utterly sick and disgusted with the whole cold-blooded game of cat and mouse, but the police needed my evidence about the Notes and the burglary, and did not intend to let me slip out of their clutches. Dawson was very civil and pleasant, but I was in fact as tightly held upon his string as was the wretched Hagan. So I went on to Holland with that quick-change artist, and watched him come on board the steamer at Parkeston Quay, dressed as a rather German-looking commercial traveller, eager for war commissions upon smuggled goods. This sounds absurd, but his get-up seemed somehow to suggest the idea. Then I went below. Dawson always kept away from me whenever Hagan might have seen us together."

The passage across to Holland was free from incident; there was no sign that we were at war, and Continental traffic was being carried serenely on, within easy striking distance of the German submarine base at Zeebrugge. The steamer had drawn in to the Hook beside the train, and Hagan was approaching the gangway, suit-case in hand. The man was on the edge of safety; once upon Dutch soil, Dawson could not have laid hands upon him. He would have been a neutral citizen in a neutral country, and no English warrant would run against him. But between Hagan and the gangway suddenly interposed the tall form of the ship's captain; instantly the man was ringed about by officers, and before he could say a word or move a hand he was gripped hard and led across the deck to the steamer's chart-house. Therein sat Dawson, the real, undisguised Dawson, and beside him sat Richard Cary. Hagan's face, which two minutes earlier had been glowing with triumph and with the anticipation of German gold beyond the dreams of avarice, went white as chalk. He staggered and gasped as one stabbed to the heart, and dropped into a chair. His suit-case fell from his relaxed fingers to the floor.

"Give him a stiff brandy-and-soda," directed Dawson, almost kindly, and when the victim's colour had ebbed back a little from his overcharged heart, and he had drunk deep of the friendly cordial, the detective put him out of pain. The game of cat and mouse was over.

"It is all up, Hagan," said the detective gently. "Face the music and make the best of it, my poor friend. This is Mr. Richard Cary, and you have not for a moment been out of our sight since you left London for the North four days ago."

When I had completed the writing of his story I showed the MS. to Richard Cary, who was pleased to express a general approval. "Not at all bad, Copplestone," said he, "not at all bad. You have clothed my dry bones in real flesh and blood. But you have missed what to me is the outstanding feature of the whole affair, that which justifies to my mind the whole rather grubby business. Let me give you two dates. On May 25 two copies of my faked Notes were shepherded through to Holland and reached the Germans; on May 31 was fought the Battle of Jutland. Can the brief space between these dates have been merely an accident? I cannot believe it. No, I prefer to believe that in my humble way I induced the German Fleet to issue forth and to risk an action which, under more favourable conditions for us, would have resulted in their utter destruction. I may be wrong, but I am happy in retaining my faith."

"What became of Hagan?" I asked, for I wished to bring the narrative to a clean artistic finish.

"I am not sure," answered Cary, "though I gave evidence as ordered by the court-martial. But I rather think that I have here Hagan's epitaph." He took out his pocket-book, and drew forth a slip of paper upon which was gummed a brief newspaper cutting. This he handed to me, and I read as follows:

"The War Office announces that a prisoner who was charged with espionage and recently tried by court-martial at the Westminster Guildhall was found guilty and sentenced to death. The sentence was duly confirmed and carried out yesterday morning."

Two months passed. Summer, what little there was of it, had gone, and my spirits were oppressed by the wet and fog and dirt of November in the North. I desired neither to write nor to read. My one overpowering longing was to go to sleep until the war was over and then to awake in a new world in which a decent civilised life would once more be possible.

In this unhappy mood I was seated before my study fire when a servant brought me a card. "A gentleman," said she, "wishes to see you. I said that you were engaged, but he insisted. He's a terrible man, sir."

I looked at the card, annoyed at being disturbed; but at the sight of it my torpor fell from me, for upon it was written the name of that detective officer whom in my story I had called William Dawson, and in the corner were the letters "C.I.D." (Criminal Investigation Department). I had become a criminal, and was about to be investigated!

CHAPTER II

AT CLOSE QUARTERS

Dawson entered, and we stood eyeing one another like two strange dogs. Neither spoke for some seconds, and then, recollecting that I was a host in the presence of a visitor, I extended a hand, offered a chair, and snapped open a cigarette case.
