But suddenly I remembered a thing I once heard in Rhodesia from old Peter Pienaar. I have quoted Peter already in this narrative. He was the best scout I ever knew, and before he had turned respectable he had been pretty often on the windy side of the law, when he had been wanted badly by the authorities. Peter once discussed with me the question of disguises, and he had a theory which struck me at the time. He said, barring absolute certainties like fingerprints, mere physical traits were very little use for identification if the fugitive really knew his business. He laughed at things like dyed hair and false beards and such childish follies. The only thing that mattered was what Peter called “atmosphere.”
If a man could get into perfectly different surroundings from those in which he had been first observed, and—this is the important part—really play up to these surroundings and behave as if he had never been out of them, he would puzzle the cleverest detectives on earth. And he used to tell a story of how he once borrowed a black coat and went to church and shared the same hymnbook with the man that was looking for him. If that man had seen him in decent company before he would have recognized him; but he had only seen him snuffing the lights in a public-house with a revolver.
The recollection of Peter’s talk gave me the first real comfort that I had had that day. Peter had been a wise old bird, and these fellows I was after were about the pick of the aviary. What if they were playing Peter’s game? A fool tries to look different: a clever man looks the same and is different.
Again, there was that other maxim of Peter’s which had helped me when I had been a roadman. “If you are playing a part, you will never keep it up unless you convince yourself that you are it.” That would explain the game of tennis. Those chaps didn’t need to act, they just turned a handle and passed into another life, which came as naturally to them as the first. It sounds a platitude, but Peter used to say that it was the big secret of all the famous criminals.
It was now getting on for eight o’clock, and I went back and saw Scaife to give him his instructions. I arranged with him how to place his men, and then I went for a walk, for I didn’t feel up to any dinner. I went round the deserted golf-course, and then to a point on the cliffs farther north beyond the line of the villas.
On the little trim newly-made roads I met people in flannels coming back from tennis and the beach, and a coastguard from the wireless station, and donkeys and pierrots padding homewards. Out at sea in the blue dusk I saw lights appear on the Ariadne and on the destroyer away to the south, and beyond the Cock sands the bigger lights of steamers making for the Thames. The whole scene was so peaceful and ordinary that I got more dashed in spirits every second. It took all my resolution to stroll towards Trafalgar Lodge about half-past nine.
On the way I got a piece of solid comfort from the sight of a greyhound that was swinging along at a nursemaid’s heels. He reminded me of a dog I used to have in Rhodesia, and of the time when I took him hunting with me in the Pali hills. We were after rhebok, the dun kind, and I recollected how we had followed one beast, and both he and I had clean lost it. A greyhound works by sight, and my eyes are good enough, but that buck simply leaked out of the landscape. Afterwards I found out how it managed it. Against the grey rock of the kopjes it showed no more than a crow against a thundercloud. It didn’t need to run away; all it had to do was to stand still and melt into the background.
Suddenly as these memories chased across my brain I thought of my present case and applied the moral. The Black Stone didn’t need to bolt. They were quietly absorbed into the landscape. I was on the right track, and I jammed that down in my mind and vowed never to forget it. The last word was with Peter Pienaar.
Scaife’s men would be posted now, but there was no sign of a soul. The house stood as open as a marketplace for anybody to observe. A three-foot railing separated it from the cliff road; the windows on the ground-floor were all open, and shaded lights and the low sound of voices revealed where the occupants were finishing dinner. Everything was as public and aboveboard as a charity bazaar. Feeling the greatest fool on earth, I opened the gate and rang the bell.
A man of my sort, who has travelled about the world in rough places, gets on perfectly well with two classes, what you may call the upper and the lower. He understands them and they understand him. I was at home with herds and tramps and roadmen, and I was sufficiently at my ease with people like Sir Walter and the men I had met the night before. I can’t explain why, but it is a fact. But what fellows like me don’t understand is the great comfortable, satisfied middle-class world, the folk that live in villas and suburbs. He doesn’t know how they look at things, he doesn’t understand their conventions, and he is as shy of them as of a black mamba. When a trim parlourmaid opened the door, I could hardly find my voice.
I asked for Mr. Appleton, and was ushered in. My plan had been to walk straight into the dining-room, and by a sudden appearance wake in the men
