"Yes, Mr. Morse, why?"
"Then in some of those quaint, old-fashioned towns you have seen the storks nesting on the roofs of the houses?"
I remembered that I had.
"Well, I've got a pair of storks – they arrived this morning from Germany – duck and drake, or should you say cock and hen? – at any rate, I've a sort of idea of trying to domesticate them, and to that end have had a nest constructed on the roof of this building, where they will be sheltered by the parapet and be high up above the roof of the City. What do you say to going to have a look at them and see if they're all right?"
Extraordinary man! He had always some odd or curious idea in his mind to improve his artificial fairyland. Nothing loth, we left Pu-Yi and ascended a winding staircase to the roof of the great building. Save for the lantern in the center, it was flat and made a not unpleasant promenade. The storks were at present in a cage, and could only be distinguished as bundles of dirty feathers in a miscellaneous litter. I thought my friend's chance of domesticating them was very small, but he seemed to be immensely interested in the problem.
When we had talked it over, he gave me a cigar and we began to promenade the whole length of the roof. As I have said, the night was clear and calm. Again the great stars globed themselves in heaven with an incomparable glory unknown and unsuspected by those down below. The silence was profound, the air like iced wine.
From where we were, we had a bird's-eye view of the whole City. Grand Square lay immediately at our feet, brilliantly illuminated as usual. Not a living soul was to be seen; only the dragon-fountain glittered with mysterious life. To the right, beyond the encircling buildings of the Square, stood the Palacete Mendoza surrounded by its gardens, a square, white, sleeping pile. I sent a mental greeting to Juanita. So high was the roof on which we stood that only one of the towers or cupolas rose much above us. It was the dome of the observatory, exactly opposite on the other side of Grand Square.
"There is some one who isn't much troubled by sub-lunary affairs," I said, pointing over the machicolade.
Morse nodded, and expelled a blue cloud of smoke. "I guess old Chang is the most contented fellow on earth," he said. "He is Professor, you know, Professor Chang, and an honorary M.A. of Oxford University. I had him from the Imperial Chinese Observatory at Pekin, and I am told he is on the track of a new comet, or something, which is to be called after me when he has discovered it – thus conferring immortality upon yours truly!
"It is an odd temper of mind," he went on more seriously, "that can spend a whole life in patient seclusion, peering into the unknown, and what, after all, is the unknowable. Still, he is happy, and that is the end of human endeavor."
He sighed, and with renewed interest I stared out at the round dome. The slit over the telescope was open, which showed that the astronomer was at work. In the gilded half-circle of the cupola, it was exactly like a cut in an orange.
I was about to make a remark, when an extraordinary thing happened.
Without any hint or warning, there was a loud, roaring sound, like that of some engine blowing off steam. With a "whoosh," a great column of fire, like golden rain, rose up out of the dark aperture in the dome, towering hundreds of feet in the sky, like the veritable comet for which old Chang was searching, and burst high in the empyrean with a dull explosion, followed by a swarm of brilliant, blue-white stars.
Some one inside the observatory had fired a gigantic rocket.
Morse gave a shout of surprise. He had a fresh cigar in his hand, and, unknowingly, he dropped it and mechanically bit the end of his thumb instead.
"What was that?" I cried, echoing his shout.
He didn't answer, but grew very white as he stepped up to the parapet, placed his hand upon the stone, and leant forward.
I did the same, and for nearly a minute we stared at the white, circular tower in silence.
Nothing happened. There was the black slit in the gold, enigmatic and undisturbed.
"Some experiment," I stammered at length. "Professor Chang is at work upon some problem."
Morse shook his head. "Not he! I'll swear that old Chang would never be letting off fireworks without consulting or warning Pu-Yi. Kirby, there is some black business stirring! We must look into this. I don't like it at all – hark!"
He suddenly stopped speaking, and put his hand to his ear. His whole face was strained in an ecstasy of listening, which cut deep gashes into that stern, gnarled old countenance.
I listened also, and with dread in my heart. Instinctively and without any process of reasoning, I knew that in some way or other the horror was upon us again. My lips went dry and I moistened them with the tip of my tongue; and, without conscious thought, my hand stole round to my pistol pocket and touched the cold and roughened stock of an automatic Webley.
Then I heard what Morse must have heard at first.
The air all around us was vibrating, and swiftly the vibration became a throb, a rhythmic beat, and then a low, menacing roar which grew louder and louder every second.
We had turned to each other, understanding at last, and the same word was upon our lips when the thing came – it happened as rapidly as that.
Skimming over the top of the distant Palacete like some huge night-hawk, and with a noise like a machine gun, came a venomous-looking, fast-flying monoplane. It swept down into Grand Square like a living thing, just as the noise ceased suddenly and echoed into silence. It alighted at one end and on the side of the fountain nearest the observatory, ran over the smooth wood-blocks for a few yards, and stopped. It was as though the hawk had pounced down upon its prey, and every detail was distinct and clear in the brilliant light of the lamps in the Square below.
Both of us seemed frozen where we stood. I know, for my part, all power of motion left me. A choking noise came from Morse's throat, and then we heard a cry and from immediately below us came the figure of Pu-Yi, hurrying down the library steps and running towards the aeroplane, which was still a considerable distance from him.
The next thing happened very quickly. A door at the foot of the observatory tower opened, and out came what we both thought was the figure of the astronomer. He was a tall, bent, old man, habitually clothed in a padded, saffron-colored robe with a hood, something like that of a monk.
"Chang!" I said in a hoarse whisper, when Pu-Yi stopped short in his tracks, lifted his arm, and there was the crack of a pistol.
The figure beyond, which was hurrying towards the monoplane, swerved aside. The robe of padded silk fell from it and disclosed a tall man in dark, European clothes. He dodged and writhed like an eel as Pu-Yi emptied his automatic at him, apparently without the least result. Then I saw that he was at the side of the aeroplane, scrambling up into the fuselage assisted by the pilot in leather hood and goggles.
He was up the side of the boat-like structure in a second, and then, with one leg thrown over the car he turned and took deliberate aim at Pu-Yi. There was one crack, he waited for an instant to be sure, and saw that it was enough. Then there was a chunk of machinery, two or three loud explosions, a roar, and the wings of the venomous night-hawk moved rapidly over the parquet, chased by a black shadow. It gathered speed, lifted, tilted upwards, and, clearing the buildings at the far end of the Square, hummed away into the night.
It was thus that Mark Antony Midwinter escaped from the City in the Clouds. He had been there all the time. He had murdered poor old Chang many hours before, and impersonated him with complete success. The food of the recluse was brought to him by servants and placed in an outer room so that he should never be disturbed during his calculations. He had received it with his usual muttered acknowledgments through a little guichet in the wooden partition which separated the anteroom from the telescope chamber itself. No one had ever thought of doubting that the astronomer himself was there as usual. The whole thing was most carefully planned beforehand with diabolic ingenuity and resource.
CHAPTER FIFTEEN
It was just three weeks after the murder of Pu-Yi, and once more I sat in my chambers in Piccadilly. The day had been cloudy, and now, late in the afternoon, a heavy fog had descended upon the town through which fell a cold and intermittent rain.
Up there, in the City in the Clouds, perhaps the sun was pouring down upon its spires and cupolas, but London, Piccadilly, was lowering and sad.
Lord Arthur Winstanley and Captain Pat Moore had just left me, both of them glum and silent. It went to my heart not to take them into my full confidence, but to do so was impossible. I had told them much of the recent events in the City – I could not tell them everything, for they would not have understood. Certainly I could have relied upon their absolute discretion, but, in view of what was going to happen that very night, I was compelled to keep my own counsel. They had not lived through what I had recently. Their minds were not tuned, as mine was, to the sublime disregard and aloofness from English law which obtained in Morse's gigantic refuge. Certainly neither of them would have agreed to what I proposed to do that night.
Preston came quietly into the library. He pulled the curtains and made up the fire. The face of Preston was grim and disapproving. He looked much as he looked when – what ages ago it seemed! – I departed his comfortable care to become the landlord of the "Golden Swan."
"I'm not at home to any one, Preston," I said, "except to Mr. Sliddim, who ought to be here in a few minutes. Of course, that doesn't apply to Mr. Rolston."
"Very good, Sir Thomas, thank you, Sir Thomas," said Preston, scowling at the mention of the name. Poor fellow, he didn't in the least understand why I should be receiving the furtive and melancholy Sliddim so often, and should sit with him in conference for long hours! Afterwards, when it was all over, I interrogated my faithful servant, and the state of his mind during that period proved to have been startling.
This seems the place in which to explain exactly what had happened up to date.
When Midwinter had escaped, we found the corpse of poor old Professor Chang, and the whole plan was revealed to us. Pu-Yi had been shot through the heart. His death must have been instantaneous. For several days Morse was in a terrible state of depression and remorse. He said that there was a curse upon him, and it was with the greatest difficulty that Rolston and I could bring him into a more reasonable frame of mind. The long strain had worn down even that iron resolution, but, for Juanita's sake, I knew that I must stand by him to the end.
Accordingly, there was nothing else for it, Rolston and I took entire charge of everything. I had never felt inclined to go back from the very beginning. Now my resolution was firm to see it through to the end.
Rolston pursued his own plans, and London very shortly knew that Gideon Mendoza Morse and his lovely daughter were about to reappear in the world. It gave my little, red-haired friend intense pleasure to organize this mild press campaign from the office of the Evening Special. I placed him in complete control, to the intense joy of Miss Dewsbury and the disgust of the older members of the staff. Be that as it may, the thing was done, and every one knew that Birmingham House had been taken by the millionaire.
It was then, having organized things as perfectly as I could at the City, placing Kwang-Su, the gigantic gate-keeper of the ground inclosure, in charge of the staff, that I myself descended into the world as unobtrusively as possible. For a day or two I remained in seclusion at the "Golden Swan," and during those two days saw no one but the Honest Fool, Mrs. Abbs, my housekeeper, and – Sliddim, the private inquiry agent.
Personally, while I quite appreciated the fellow's skill in his own dirty work, and while indeed I owed him a considerable debt in the matter of Bill Rolston's first disappearance, I disliked him too much ever to have thought of him as a help in the very serious affair on which I was engaged. It was Rolston, as usual, who changed my mind. He saw farther than I did. He realized the essential secrecy and fidelity of the odd creature whom chance had unearthed from among the creeping things of London, and in the end he became an integral part of the plot.
He was told, of course, no more than was necessary. He was not by any means in our full confidence. But he was given a part to play, and promised a reward, if he played it well, that would make him independent for life. Let me say at once that he fulfilled his duty with admirable skill, and, when he received his check from Mr. Morse, vanished forever from our ken. I have no doubt that he is spying somewhere or other on the globe at this moment, but I have no ambition to meet him again.
Mr. Sliddim, considerably furbished up in personal appearance, was made caretaker at Birmingham House in Berkeley Square. He had not been in that responsible position for more than ten days when our fish began to nibble at the bait.
In a certain little public house by some mews at the back of Berkeley Square, a little public house which Mr. Sliddim was instructed – and needed no encouragement – to frequent, he was one day accosted by a tall, middle-aged man with a full, handsome face and a head of curling, gray hair. This man was dressed in a seedy, shabby-genteel style, and soon became intimate with our lure.
Certainly, to give him his due, Sliddim must have been a supreme actor in his way. He did the honest, but intensely stupid caretaker to the life. Mark Antony Midwinter was completely taken in and pumped our human conduit for all he was worth, until he was put in possession of an entirely fictitious set of circumstances, arranged with the greatest care to suit my plans.
