He had often been to the Armstrongs', on little police jobs of the philanthropist; and, now he came to think of it, it was in itself a depressing house. The rooms were very high and very cold; the decoration mean and provincial; the draughty corridors were lit by electricity that was bleaker than moonlight. And though the old man's scarlet face and silver beard had blazed like a bonfire in each room or passage in turn, it did not leave any warmth behind it. Doubtless this spectral discomfort in the place was partly due to the very vitality and exuberance of its owner; he needed no stoves or lamps, he would say, but carried his own warmth with him. But when Merton recalled the other inmates, he was compelled to confess that they also were as shadows of their lord. The moody man-servant, with his monstrous black gloves, was almost a nightmare; Royce, the secretary, was solid enough, a big bull of a man, in tweeds, with a short beard; but the straw-coloured beard was startlingly salted with grey like the tweeds, and the broad forehead was barred with premature wrinkles. He was good-natured enough also, but it was a sad sort of good-nature, almost a heart-broken sort--he had the general air of being some sort of failure in life. As for Armstrong's daughter, it was almost incredible that she was his daughter; she was so pallid in colour and sensitive in outline. She was graceful, but there was a quiver in the very shape of her that was like the lines of an aspen. Merton had sometimes wondered if she had learnt to quail at the crash of the passing trains.
"You see," said Father Brown, blinking modestly, "I'm not sure that the Armstrong cheerfulness is so very cheerful--for other people. You say that nobody could kill such a happy old man, but I'm not sure; ne nos inducas in tentationem. If ever I murdered somebody," he added quite simply, "I dare say it might be an Optimist.""Why?" cried Merton amused. "Do you think people dislike cheerfulness?""People like frequent laughter," answered Father Brown, "but Idon't think they like a permanent smile. Cheerfulness without humour is a very trying thing."They walked some way in silence along the windy grassy bank by the rail, and just as they came under the far-flung shadow of the tall Armstrong house, Father Brown said suddenly, like a man throwing away a troublesome thought rather than offering it seriously: "Of course, drink is neither good nor bad in itself.
But I can't help sometimes feeling that men like Armstrong want an occasional glass of wine to sadden them."Merton's official superior, a grizzled and capable detective named Gilder, was standing on the green bank waiting for the coroner, talking to Patrick Royce, whose big shoulders and bristly beard and hair towered above him. This was the more noticeable because Royce walked always with a sort of powerful stoop, and seemed to be going about his small clerical and domestic duties in a heavy and humbled style, like a buffalo drawing a go-cart.
He raised his head with unusual pleasure at the sight of the priest, and took him a few paces apart. Meanwhile Merton was addressing the older detective respectfully indeed, but not without a certain boyish impatience.
"Well, Mr. Gilder, have you got much farther with the mystery?""There is no mystery," replied Gilder, as he looked under dreamy eyelids at the rooks.
"Well, there is for me, at any rate," said Merton, smiling.
"It is ****** enough, my boy," observed the senior investigator, stroking his grey, pointed beard. "Three minutes after you'd gone for Mr. Royce's parson the whole thing came out. You know that pasty-faced servant in the black gloves who stopped the train?""I should know him anywhere. Somehow he rather gave me the creeps.""Well," drawled Gilder, "when the train had gone on again, that man had gone too. Rather a cool criminal, don't you think, to escape by the very train that went off for the police?""You're pretty sure, I suppose," remarked the young man, "that he really did kill his master?""Yes, my son, I'm pretty sure," replied Gilder drily, "for the trifling reason that he has gone off with twenty thousand pounds in papers that were in his master's desk. No, the only thing worth calling a difficulty is how he killed him. The skull seems broken as with some big weapon, but there's no weapon at all lying about, and the murderer would have found it awkward to carry it away, unless the weapon was too small to be noticed.""Perhaps the weapon was too big to be noticed," said the priest, with an odd little giggle.
Gilder looked round at this wild remark, and rather sternly asked Brown what he meant.
"Silly way of putting it, I know," said Father Brown apologetically. "Sounds like a fairy tale. But poor Armstrong was killed with a giant's club, a great green club, too big to be seen, and which we call the earth. He was broken against this green bank we are standing on.""How do you mean?" asked the detective quickly.
Father Brown turned his moon face up to the narrow facade of the house and blinked hopelessly up. Following his eyes, they saw that right at the top of this otherwise blind back quarter of the building, an attic window stood open.
"Don't you see," he explained, pointing a little awkwardly like a child, "he was thrown down from there?"Gilder frowningly scrutinised the window, and then said:
"Well, it is certainly possible. But I don't see why you are so sure about it."Brown opened his grey eyes wide. "Why," he said, "there's a bit of rope round the dead man's leg. Don't you see that other bit of rope up there caught at the corner of the window?"At that height the thing looked like the faintest particle of dust or hair, but the shrewd old investigator was satisfied.
"You're quite right, sir," he said to Father Brown; "that is certainly one to you."Almost as he spoke a special train with one carriage took the curve of the line on their left, and, stopping, disgorged another group of policemen, in whose midst was the hangdog visage of Magnus, the absconded servant.
