"I suppose we can trust him? He certainly saved us from disaster coming out of the cavern."

I shuddered; I did not want to think of that blood-stained hole of horror any more.

"Yes, I think he can he trusted. He has everything to gain, and can do no harm that I can see. I cannot operate the keys of the apparatus, but I know the Morse code, and if I stand by him I can check each letter as he sends it out."

Then I had an inspiration too. "Good! And now I think I can make it quite sure. I can remember the private code of the Air Police with hardly a gap. We will call up Plymouth, and all the police boats now flying, in that private code. Meanwhile, we had better run out to sea again while you are taking it down."

Again I turned the ship, and as we spiralled up and out again, I formed the message in my mind and translated it, word for word, into the letters of the code, which Danjuro took down in pencil upon a sheet of his pocket-book.

When I had finished, and as the message was necessarily rather a long one it took some time, Danjuro marched Gascoigne away to the rear cabin, where Vargus was lying. It was there, you may remember, that the wireless apparatus was installed.

We were now reaching a great height, far above any of the regular air-lanes, and I felt quite secure from any attack. Land, sea, every reminder of the world below, had vanished utterly. With hardly a sound from the magic engines we floated in a haze of gold chrysophrase. It was like a happy dream, though never was dream so beautiful.

Connie stole in again. "I thought I would leave Thumbwood and Wilson alone," she said. "They have been sitting side by side and whispering to each other ever since we started. Neither of them seems to have the least curiosity as to where we are or where we"re going."

"How thoughtful of you, dearest! Was that the only reason you came in here!"

The rest of the conversation is not a part of this story. It lasted a long time as we droned round great five-mile circles of the upper air.

And then a telephone rang at my ear.

Danjuro was speaking. The message had been received at Plymouth, and an answer had been coming through for the last ten minutes. He was writing it down, letter by letter, from Gascoigne"s dictation. Shortly afterwards he brought it in to me, and as I read it off the world closed round me again and fairyland vanished.

Triumph filled my veins and reddened my blood. The message came from Muir Lockhart, who was at Plymouth again, and was one shout of wonder and congratulation. "The whole world will thank you," it concluded.

For a little time I was intoxicated by that message. I saw myself a hero, vindicated a thousand times in the eyes of all men, the Chief of Air Police whose name would be historical. I think there are few men of my age who would not have had their moment of vainglory; we are made so.

But as I read the message to the man who had brought it, I realized that I had done nothing, after all, and that everything was due to his marvellous brilliancy and courage.

Thank Heaven that I realized it without a pang of envy, and I told him what I thought of him in no unstinted way.

He heard me to the end with no change of countenance. When I had done, he said: "You have been very kind, Sir John, and I greatly appreciate what you have said. If, indeed, you are indebted to me in any way for the help I have been able to give, you can repay me, if you will."

"To the half of my kingdom!" I said, with a laugh, though I was in dead earnest all the same.

"That is a promise, Sir John?" He looked down at me with magnetic eyes.

"A promise, Danjuro."

"Then, while I live, I ask you to say nothing whatever of my part in this affair. I wish it kept as secret as possible; some little part must leak out; there will be investigations, public trials, and so forth. But much can be kept secret, and it rests with you and Thumbwood. And as I have your promise, my mind is at rest."

"But this is madness, Danjuro! You are owed the thanks of two continents. You ..."

He interrupted me.

"I want nothing of the sort. I have had your thanks, and that is sufficient. The work itself is enough. My usefulness to Mr. Van Adams, the endeavour of my whole life, would be destroyed if anything were known."

Reluctantly I promised. "But Mr. Van Adams, I shall tell _him_ everything!" I said.

Danjuro bowed his head. A faint flush came into his yellow face. "If you think I have done anything worth it," he replied, with a curious and touching silence.

And this was the man with the panther in his soul! For the American millionaire he had supreme love, with devotion--worship--and for no one and nothing else on earth above or below it.

A man with a single obsession, a man of one idea. Well, most of the great men in life have been that....

I steered for Plymouth at full speed, coming down to three thousand feet. In a flash the jagged coast, fringed with a thin line of white, came clear to view. We sped from the Atlantic, over the narrow peninsula of land which divides it from the Channel, and then turned east. The Bay, with St. Michael"s Mount looking like a tiny white pebble, gave place to the long, menacing snout of the Lizard, and, as a few minutes later we neared Falmouth, a flight of airships rose from the water of that mighty harbour and came up to join us like a flock of gulls, the big Klaxon electric horns blaring a welcome. Dead Man"s Rock and Gall Island, Looe, Mevagissey, Fowey--all slipped away astern, and the bluff outlines of Rame Head, from which the Devon watchers first signalled the Armada, came rushing into view. I had been speeding far ahead, turning back, flying all round the escorting patrol boats, which were doing all they knew, letting them see what a wonder had come into our hands, and rejoicing more and more in the powers of the ship, as I found them one by one. Now I slowed down, and signalled by horn to the leading vessel of the flotilla.

As we turned and entered Plymouth Sound, the others spread themselves out in a great wedge, of which I was leader, like a skein of wild geese upon the wing. A salute of guns boomed out as we flew high on the Breakwater, and all the bells of Plymouth were ringing as I swooped down into the sea-drome.

And all this time, for three-quarters of an hour or more, our two prisoners had been alone together in the aft cabin, where the tools and spare parts were stored. Neither I nor Danjuro had given them a further thought, and it was the one fatal mistake we made upon that morning of triumph.

Thumbwood had, however, been in to look at them once or twice, and had seen nothing disturbing. Certainly, when some of my men came to take them to the station, they were lying sullen in their bonds, and not saying a word to each other of any kind.

But by that time the mischief was doubtless done.

s.p.a.ce begins to press upon me. There are still two strange and unforgettable scenes to add to this narrative, further tragedies to set down. The last scene of all, which I have called "The Epilogue," was not written for a year after the earlier part of this story, which is now published as a whole for the first time. Why this is so will become clear as you read on, if you care to follow me to the very end.

But as I would not weary you, I will only indicate the happenings during the rest of that day at Plymouth in the briefest possible fashion. I am impatient to bring the story up to the hour of eleven-thirty of the same night.

Immediately we were at rest on the placid waters of the sea-drome, Muir Lockhart, with a strong force of Air Police, came aboard. Constance and her maid were taken in a motor-boat to one of my patrol ships, which started with them for the Hounslow Aerodrome within half an hour of our arrival. We both of us thought it best that she should proceed to London immediately, and going by air in a Government ship, she would escape all annoyance and publicity.

All approach to the sea-drome was barred, and though the Hoe was crowded with spectators, none of them could approach anywhere near to us. When I had given Lockhart an outline of what had occurred, the two prisoners were taken over the pool with a strong guard, and run up in the private lift to the A.P. station, where there was a strong cell ready to receive them. Then I was free to show my colleague, himself an expert airman, the wonders of our capture.

I was doing this--we were in the pilot"s cabin--when one of my men came in and said that a motor-launch had come alongside from the private air-yacht _May Flower_, which was moored not a hundred yards away. I had noticed, when descending, that a magnificent yacht was close by, but I did not identify it as Mr. Van Adams" ship. It appeared that he had been sleeping aboard for the last two or three nights, since he had flown down from London for the funeral, and was now alongside.

Van Adams, of course, was an exception to all ordinary rules, and in a minute he was shaking hands in the private saloon and betraying a most lively curiosity as to our adventures. I put Danjuro to satisfy him, and when we had discussed a bottle of Helzephron"s champagne, I left a couple of trusted men to guard the ship, and went ash.o.r.e. Danjuro returned to the _May Flower_ with his patron.

The rest of the day was a whirl of business and excitement, though I managed to get three hours much needed sleep in the afternoon.

Wires from the Government, from America, from Royalty, poured in, in a never-ceasing stream. There were innumerable officials to see, the correspondents of the great newspapers to satisfy with some sort of story--a hundred things to do and arrange for. The whole of England was in a ferment, and the stone building of the Air Police on the Hoe was, for a few hours, the centre of it all. The air was thick with patrol ships, warning off aviators of all kinds from approaching the Pirate Ship, which lay at rest and harmless by the north wall of the pool.

Just before I retired to rest the news of what was called "The Battle of the Moor" began to come through. The pirates, seeing their ship gone, had rushed up again into the house, and had held it with the courage of desperation. Only three of them had survived, and were now locked up in the police-station at Penzance.

... It would take many pages to detail the events of that crowded day, which did not end for me until ten o"clock at night, for I was forced to attend a congratulatory dinner at the "Royal." Previous to that I had found it necessary to summon Danjuro from the _May Flower_, where he had remained quietly with Mr. Van Adams during the day. It was necessary that I should be restored to something like my former self, and only Danjuro could make me blond again! My moustache, alas! he could not restore.

I had arranged to sleep at the station, where there were several bedrooms, and about ten-thirty I pa.s.sed the sentry and entered the grounds.

Plymouth was now quiet. It was a hot, dark night, with neither moon nor stars. During the day the weather had changed, and now thunder muttered far away at sea and amethyst sheet-lightning flickered upon the horizon.

Now and again a drop of hot rain fell.
