While I was falling I made up my mind on my conduct. I must be intoxicated, for I knew the infinite sympathy of the British soldier towards those thus overtaken. They pulled me to my feet, and the man I had descended on rubbed his skull and blasphemously demanded explanations.

'Gen'lmen,' I hiccoughed, 'I 'pologize. I was late for this bl-blighted train and I mus' be in E'inburgh 'morrow or I'll get the sack. I 'pologize. If I've hurt my friend's head, I'll kiss it and make it well.'

At this there was a great laugh. 'Ye'd better accept, Pete,' said one. 'It's the first time anybody ever offered to kiss your ugly heid.'

A man asked me who I was, and I appeared to be searching for a card-case.

'Losht,' I groaned. 'Losht, and so's my wee bag and I've bashed my po' hat. I'm an awful sight, gen'lmen-an awful warning to be in time for trains. I'm John Johnstone, managing clerk to Messrs Watters, Brown & Elph'stone, 923 Charl'tte Street, E'inburgh. I've been up north seein' my mamma.'

'Ye should be in France,' said one man.

'Wish't I was, but they wouldn't let me. "Mr Johnstone," they said, "ye're no dam good. Ye've varicose veins and a bad heart," they said. So I says, "Good mornin', gen'lmen. Don't blame me if the country's ru'ned". That's what I said.'

I had by this time occupied the only remaining s.p.a.ce left on the floor. With the philosophy of their race the men had accepted my presence, and were turning again to their own talk. The train had got up speed, and as I judged it to be a special of some kind I looked for few stoppings. Moreover it was not a corridor carriage, but one of the old-fashioned kind, so I was safe for a time from the unwelcome attention of conductors. I stretched my legs below the seat, rested my head against the knees of a brawny gunner, and settled down to make the best of it.

My reflections were not pleasant. I had got down too far below the surface, and had the naked feeling you get in a dream when you think you have gone to the theatre in your nightgown. I had had three names in two days, and as many characters. I felt as if I had no home or position anywhere, and was only a stray dog with everybody's hand and foot against me. It was an ugly sensation, and it was not redeemed by any acute fear or any knowledge of being mixed up in some desperate drama. I knew I could easily go on to Edinburgh, and when the police made trouble, as they would, a wire to Scotland Yard would settle matters in a couple of hours. There wasn't a suspicion of bodily danger to restore my dignity. The worst that could happen would be that Ivery would hear of my being befriended by the authorities, and the part I had settled to play would be impossible. He would certainly hear. I had the greatest respect for his intelligence service.

Yet that was bad enough. So far I had done well. I had put Gresson off the scent. I had found out what Bullivant wanted to know, and I had only to return unostentatiously to London to have won out on the game. I told myself all that, but it didn't cheer my spirits. I was feeling mean and hunted and very cold about the feet.

But I have a tough knuckle of obstinacy in me which makes me unwilling to give up a thing till I am fairly choked off it. The chances were badly against me. The Scottish police were actively interested in my movements and would be ready to welcome me at my journey's end. I had ruined my hat, and my clothes, as Amos had observed, were not respectable. I had got rid of a four-days' beard the night before, but had cut myself in the process, and what with my weather-beaten face and tangled hair looked liker a tinker than a decent bagman. I thought with longing of my portmanteau in the Pentland Hotel, Edinburgh, and the neat blue serge suit and the clean linen that reposed in it. It was no case for a subtle game, for I held no cards. Still I was determined not to chuck in my hand till I was forced to. If the train stopped anywhere I would get out, and trust to my own wits and the standing luck of the British Army for the rest.

The chance came just after dawn, when we halted at a little junction. I got up yawning and tried to open the door, till I remembered it was locked. Thereupon I stuck my legs out of the window on the side away from the platform, and was immediately seized upon by a sleepy Seaforth who thought I contemplated suicide.

'Let me go,' I said. 'I'll be back in a jiffy.'

'Let him gang, jock,' said another voice. 'Ye ken what a man's like when he's been on the bash. The cauld air'll sober him.'

I was released, and after some gymnastics dropped on the metals and made my way round the rear of the train. As I clambered on the platform it began to move, and a face looked out of one of the back carriages. It was Linklater and he recognized me. He tried to get out, but the door was promptly slammed by an indignant porter. I heard him protest, and he kept his head out till the train went round the curve. That cooked my goose all right. He would wire to the police from the next station.

Meantime in that clean, bare, chilly place there was only one traveller. He was a slim young man, with a kit-bag and a gun-case. His clothes were beautiful, a green Homburg hat, a smart green tweed overcoat, and boots as brightly polished as a horse chestnut. I caught his profile as he gave up his ticket and to my amazement I recognized it.

The station-master looked askance at me as I presented myself, dilapidated and dishevelled, to the official gaze. I tried to speak in a tone of authority.

'Who is the man who has just gone out?'

'Whaur's your ticket?'

'I had no time to get one at Muirtown, and as you see I have left my luggage behind me. Take it out of that pound and I'll come back for the change. I want to know if that was Sir Archibald Roylance.'

He looked suspiciously at the note. 'I think that's the name. He's a captain up at the Fleein' School. What was ye wantin' with him?'

I charged through the booking-office and found my man about to enter a big grey motor-car.

'Archie,' I cried and beat him on the shoulders.

He turned round sharply. 'What the devil-! Who are you?' And then recognition crept into his face and he gave a joyous shout. 'My holy aunt! The General disguised as Charlie Chaplin! Can I drive you anywhere, sir?'

CHAPTER NINE

I Take the Wings of a Dove

'Drive me somewhere to breakfast, Archie,' I said, 'for I'm perishing hungry.'

He and I got into the tonneau, and the driver swung us out of the station road up a long incline of hill. Sir Archie had been one of my subalterns in the old Lennox Highlanders, and had left us before the Somme to join the Flying Corps. I had heard that he had got his wings and had done well before Arras, and was now training pilots at home. He had been a light-hearted youth, who had endured a good deal of rough-tonguing from me for his sins of omission. But it was the casual cla.s.s of lad I was looking for now.

I saw him steal amused glances at my appearance.

'Been seein' a bit of life, sir?' he inquired respectfully.

'I'm being hunted by the police,' I said.

'Dirty dogs! But don't worry, sir; we'll get you off all right. I've been in the same fix myself. You can lie snug in my little log hut, for that old image Gibbons won't blab. Or, tell you what, I've got an aunt who lives near here and she's a bit of a sportsman. You can hide in her moated grange till the bobbies get tired.'

I think it was Archie's calm acceptance of my position as natural and becoming that restored my good temper. He was far too well bred to ask what crime I had committed, and I didn't propose to enlighten him much. But as we swung up the moorland road I let him know that I was serving the Government, but that it was necessary that I should appear to be unauthenticated and that therefore I must dodge the police. He whistled his appreciation.

'Gad, that's a deep game. Sort of camouflage? Speaking from my experience it is easy to overdo that kind of stunt. When I was at Misieux the French started out to camouflage the caravans where they keep their pigeons, and they did it so d.a.m.ned well that the poor little birds couldn't hit 'em off, and spent the night out.'

We entered the white gates of a big aerodrome, skirted a forest of tents and huts, and drew up at a shanty on the far confines of the place. The hour was half past four, and the world was still asleep. Archie nodded towards one of the hangars, from the mouth of which projected the propeller end of an aeroplane.

'I'm by way of flyin' that bus down to Farnton tomorrow,' he remarked. 'It's the new Shark-Gladas. Got a mouth like a tree.'

An idea flashed into my mind.

'You're going this morning,' I said.

'How did you know?' he exclaimed. 'I'm due to go today, but the grouse up in Caithness wanted shootin' so badly that I decided to w.a.n.gle another day's leave. They can't expect a man to start for the south of England when he's just off a frowsy journey.'

'All the same you're going to be a stout fellow and start in two hours' time. And you're going to take me with you.'

He stared blankly, and then burst into a roar of laughter. 'You're the man to go tiger-shootin' with. But what price my commandant? He's not a bad chap, but a trifle s.h.a.ggy about the fetlocks. He won't appreciate the joke.'

'He needn't know. He mustn't know. This is an affair between you and me till it's finished. I promise you I'll make it all square with the Flying Corps. Get me down to Farnton before evening, and you'll have done a good piece of work for the country.'

'Right-o! Let's have a tub and a bit of breakfast, and then I'm your man. I'll tell them to get the bus ready.'

In Archie's bedroom I washed and shaved and borrowed a green tweed cap and a brand-new Aquascutum. The latter covered the deficiencies of my raiment, and when I commandeered a pair of gloves I felt almost respectable. Gibbons, who seemed to be a jack-of-all-trades, cooked us some bacon and an omelette, and as he ate Archie yarned. In the battalion his conversation had been mostly of race-meetings and the forsaken delights of town, but now he had forgotten all that, and, like every good airman I have ever known, wallowed enthusiastically in 'shop'. I have a deep respect for the Flying Corps, but it is apt to change its jargon every month, and its conversation is hard for the layman to follow. He was desperately keen about the war, which he saw wholly from the viewpoint of the air. Arras to him was over before the infantry crossed the top, and the tough bit of the Somme was October, not September. He calculated that the big air-fighting had not come along yet, and all he hoped for was to be allowed out to France to have his share in it. Like all good airmen, too, he was very modest about himself. 'I've done a bit of steeple-chasin' and huntin' and I've good hands for a horse, so I can handle a bus fairly well. It's all a matter of hands, you know. There ain't half the risk of the infantry down below you, and a million times the fun. Jolly glad I changed, sir.'

We talked of Peter, and he put him about top. Voss, he thought, was the only Boche that could compare with him, for he hadn't made up his mind about Lensch. The Frenchman Guynemer he ranked high, but in a different way. I remember he had no respect for Richthofen and his celebrated circus.

At six sharp we were ready to go. A couple of mechanics had got out the machine, and Archie put on his coat and gloves and climbed into the pilot's seat, while I squeezed in behind in the observer's place. The aerodrome was waking up, but I saw no officers about. We were scarcely seated when Gibbons called our attention to a motor-car on the road, and presently we heard a shout and saw men waving in our direction.

'Better get off, my lad,' I said. 'These look like my friends.'

The engine started and the mechanics stood clear. As we taxied over the turf I looked back and saw several figures running in our direction. The next second we had left the b.u.mpy earth for the smooth highroad of the air.

I had flown several dozen times before, generally over the enemy lines when I wanted to see for myself how the land lay. Then we had flown low, and been nicely dusted by the Hun Archies, not to speak of an occasional machine-gun. But never till that hour had I realized the joy of a straight flight in a swift plane in perfect weather. Archie didn't lose time. Soon the hangars behind looked like a child's toys, and the world ran away from us till it seemed like a great golden bowl spilling over with the quintessence of light. The air was cold and my hands numbed, but I never felt them. As we throbbed and tore southward, sometimes b.u.mping in eddies, sometimes swimming evenly in a stream of motionless ether, my head and heart grew as light as a boy's. I forgot all about the vexations of my job and saw only its joyful comedy. I didn't think that anything on earth could worry me again. Far to the left was a wedge of silver and beside it a cl.u.s.ter of toy houses. That must be Edinburgh, where reposed my portmanteau, and where a most efficient police force was now inquiring for me. At the thought I laughed so loud that Archie must have heard me. He turned round, saw my grinning face, and grinned back. Then he signalled to me to strap myself in. I obeyed, and he proceeded to practise 'stunts'-the loop, the spinning nose-dive, and others I didn't know the names of. It was glorious fun, and he handled his machine as a good rider coaxes a nervous horse over a stiff hurdle. He had that extra something in his blood that makes the great pilot.
