FATHER BROWN, at one period of his life, found it difficult to hang his hat on a hat–peg without repressing a slight shudder. The origin of this idiosyncrasy was indeed a mere detail in much more complicated events; but it was perhaps the only detail that remained to him in his busy life to remind him of the whole business. Its remote origin was to be found in the facts which led Dr Boyne, the medical officer attached to the police force, to send for the priest on a particular frosty morning in December.
Dr Boyne was a big dark Irishman, one of those rather baffling Irishmen to be found all over the world, who will talk scientific scepticism, materialism, and cynicism at length and at large, but who never dream of referring anything touching the ritual of religion to anything except the traditional religion of their native land. It would be hard to say whether their creed is a very superficial varnish or a very fundamental substratum; but most probably it is both, with a mass of materialism in between. Anyhow, when he thought that matters of that sort might be involved, he asked Father Brown to call, though he made no pretence of preference for that aspect of them.
'I'm not sure I want you, you know,' was his greeting. 'I'm not sure about anything yet. I'm hanged if I can make out whether it's a case for a doctor, or a policeman, or a priest.'
'Well,' said Father Brown with a smile, 'as I suppose you're both a policeman and a doctor, I seem to be rather in a minority.'
'I admit you're what politicians call an instructed minority,' replied the doctor. 'I mean, I know you've had to do a little in our line as well as your own. But it's precious hard to say whether this business is in your line or ours, or merely in the line of the Commissioners in Lunacy. We've just had a message from a man living near here, in that white house on the hill, asking for protection against a murderous persecution. We've gone into the facts as far as we could, and perhaps I'd better tell you the story as it is supposed to have happened, from the beginning.
'It seems that a man named Aylmer, who was a wealthy landowner in the West Country, married rather late in life and had three sons, Philip, Stephen, and Arnold. But in his bachelor days, when he thought he would have no heir, he had adopted a boy whom he thought very brilliant and promising, who went by the name of John Strake. His origin seems to be vague; they say he was a foundling; some say he was a gipsy. I think the last notion is mixed up with the fact that Aylmer in his old age dabbled in all sorts of dingy occultism, including palmistry and astrology, and his three sons say that Strake encouraged him in it. But they said a great many other things besides that. They said Strake was an amazing scoundrel, and especially an amazing liar; a genius in inventing lies on the spur of the moment, and telling them so as to deceive a detective. But that might very well be a natural prejudice, in the light of what happened.
Perhaps you can more or less imagine what happened. The old man left practically everything to the adopted son; and when he died the three real sons disputed the will. They said their father had been frightened into surrender and, not to put too fine a point on it, into gibbering idiocy. They said Strake had the strangest and most cunning ways of getting at him, in spite of the nurses and the family, and terrorizing him on his death–bed. Anyhow, they seemed to have proved something about the dead man's mental condition, for the courts set aside the will and the sons inherited. Strake is said to have broken out in the most dreadful fashion, and sworn he would kill all three of them, one after another, and that nothing could hide them from his vengeance. It is the third or last of the brothers, Arnold Aylmer, who is asking for police protection.'
'Third and last,' said the priest, looking at him gravely.
'Yes,' said Boyne. 'The other two are dead.' There was a silence before he continued. 'That is where the doubt comes in. There is no proof they were murdered, but they might possibly have been. The eldest, who took up his position as squire, was supposed to have committed suicide in his garden. The second, who went into trade as a manufacturer, was knocked on the head by the machinery in his factory; he might very well have taken a false step and fallen. But if Strake did kill them, he is certainly very cunning in his way of getting to work and getting away. On the other hand, it's more than likely that the whole thing is a mania of conspiracy founded on a coincidence. Look here, what I want is this. I want somebody of sense, who isn't an official, to go up and have a talk with this Mr Arnold Aylmer and form an impression of him. You know what a man with a delusion is like, and how a man looks when he is telling the truth. I want you to be the advance guard, before we take the matter up.'
'It seems rather odd,' said Father Brown, 'that you haven't had to take it up before. If there is anything in this business, it seems to have been going on for a good time. Is there any particular reason why he should send for you just now, any more than any other time?'
'That had occurred to me, as you may imagine,' answered Dr Boyne. 'He does give a reason, but I confess it is one of the things that make me wonder whether the whole thing isn't only the whim of some half–witted crank. He declared that all his servants have suddenly gone on strike and left him, so that he is obliged to call on the police to look after his house. And on making inquiries, I certainly do find that there has been a general exodus of servants from that house on the hill; and of course the town is full of tales, very one–sided tales I dare say. Their account of it seems to be that their employer had become quite impossible in his fidgets and fears and exactions; that he wanted them to guard the house like sentries, or sit up like night nurses in a hospital; that they could never be left alone because he must never be left alone. So they all announced in a loud voice that he was a lunatic, and left. Of course that does not prove he is a lunatic; but it seems rather rum nowadays for a man to expect his valet or his parlour–maid to act as an armed guard.'
'And so,' said the priest with a smile, 'he wants a policeman to act as his parlour–maid because his parlour–maid won't act as a policeman.'
'I thought that rather thick, too,' agreed the doctor; 'but I can't take the responsibility of a flat refusal till I've tried a compromise. You are the compromise.'
'Very well,' said Father Brown simply. 'I'll go and call on him now if you like.'
The rolling country round the little town was sealed and bound with frost, and the sky was as clear and cold as steel, except in the north–east where clouds with lurid haloes were beginning to climb up the sky. It was against these darker and more sinister colours that the house on the hill gleamed with a row of pale pillars, forming a short colonnade of the classical sort. A winding road led up to it across the curve of the down, and plunged into a mass of dark bushes. Just before it reached the bushes the air seemed to grow colder and colder, as if he were approaching an ice–house or the North Pole. But he was a highly practical person, never entertaining such fancies except as fancies. And he merely cocked his eye at the great livid cloud crawling up over the house, and remarked cheerfully: 'It's going to snow.'
Through a low ornamental iron gateway of the Italianate pattern he entered a garden having something of that desolation which only belongs to the disorder of orderly things. Deep–green growths were grey with the faint powder of the frost, large weeds had fringed the fading pattern of the flower–beds as if in a ragged frame; and the house stood as if waist–high in a stunted forest of shrubs and bushes. The vegetation consisted largely of evergreens or very hardy plants; and though it was thus thick and heavy, it was too northern to be called luxuriant. It might be described as an Arctic jungle. So it was in some sense with the house itself, which had a row of columns and a classical facade, which might have looked out on the Mediterranean; but which seemed now to be withering in the wind of the North Sea. Classical ornament here and there accentuated the contrast; caryatides and carved masks of comedy or tragedy looked down from corners of the building upon the grey confusion of the garden paths; but the faces seemed to be frost–bitten. The very volutes of the capitals might have curled up with the cold.
Father Brown went up the grassy steps to a square porch flanked by big pillars and knocked at the door. About four minutes afterwards he knocked again. Then he stood still patiently waiting with his back to the door and looked out on the slowly darkening landscape. It was darkening under the shadow of that one great continent of cloud that had come flying out of the north; and even as he looked out beyond the pillars of the porch, which seemed huge and black above him in the twilight, he saw the opalescent crawling rim of the great cloud as it sailed over the roof and bowed over the porch like a canopy. The great canopy with its faintly coloured fringes seemed to sink lower and lower upon the garden beyond, until what had recently been a clear and pale–hued winter sky was left in a few silver ribbons and rags like a sickly sunset. Father Brown waited, and there was no sound within.
Then he betook himself briskly down the steps and round the house to look for another entrance. He eventually found one, a side door in the flat wall, and on this also he hammered and outside this also he waited. Then he tried the handle and found the door apparently bolted or fastened in some fashion; and then he moved along that side of the house, musing on the possibilities of the position, and wondering whether the eccentric Mr Aylmer had barricaded himself too deep in the house to hear any kind of summons; or whether perhaps he would barricade himself all the more, on the assumption that any summons must be the challenge of the avenging Strake. It might be that the decamping servants had only unlocked one door when they left in the morning, and that their
