"Second item. Heaps and heaps of loose snuff, not kept in a horn, or even a pouch, but lying in heaps on the mantelpieces, on the sideboard, on the piano, anywhere. It looks as if the old gentleman would not take the trouble to look in a pocket or lift a lid.
"Third item. Here and there about the house curious little heaps of minute pieces of metal, some like steel springs and some in the form of microscopic wheels. As if they had gutted some mechanical toy.
"Fourth item. The wax candles, which have to be stuck in bottle necks because there is nothing else to stick them in. Now I wish you to note how very much queerer all this is than anything we anticipated. For the central riddle we are prepared; we have all seen at a glance that there was something wrong about the last earl. We have come here to find out whether he really lived here, whether he really died here, whether that red-haired scarecrow who did his burying had anything to do with his dying. But suppose the worst in all this, the most lurid or melodramatic solution you like. Suppose the servant really killed the master, or suppose the master isn't really dead, or suppose the master is dressed up as the servant, or suppose the servant is buried for the master; invent what Wilkie Collins' tragedy you like, and you still have not explained a candle without a candlestick, or why an elderly gentleman of good family should habitually spill snuff on the piano. The core of the tale we could imagine; it is the fringes that are mysterious. By no stretch of fancy can the human mind connect together snuff and diamonds and wax and loose clockwork."
"I think I see the connection," said the priest. "This Glengyle was mad against the French Revolution. He was an enthusiast for the ancien regime, and was trying to re-enact literally the family life of the last Bourbons. He had snuff because it was the eighteenth century luxury; wax candles, because they were the eighteenth century lighting; the mechanical bits of iron represent the locksmith hobby of Louis XVI; the diamonds are for the Diamond Necklace of Marie Antoinette."
Both the other men were staring at him with round eyes. "What a perfectly extraordinary notion!" cried Flambeau. "Do you really think that is the truth?"
"I am perfectly sure it isn't," answered Father Brown, "only you said that nobody could connect snuff and diamonds and clockwork and candles. I give you that connection off-hand. The real truth, I am very sure, lies deeper."
He paused a moment and listened to the wailing of the wind in the turrets. Then he said, "The late Earl of Glengyle was a thief. He lived a second and darker life as a desperate housebreaker. He did not have any candlesticks because he only used these candles cut short in the little lantern he carried. The snuff he employed as the fiercest French criminals have used pepper: to fling it suddenly in dense masses in the face of a captor or pursuer. But the final proof is in the curious coincidence of the diamonds and the small steel wheels. Surely that makes everything plain to you? Diamonds and small steel wheels are the only two instruments with which you can cut out a pane of glass."
The bough of a broken pine tree lashed heavily in the blast against the windowpane behind them, as if in parody of a burglar, but they did not turn round. Their eyes were fastened on Father Brown.
"Diamonds and small wheels," repeated Craven ruminating. "Is that all that makes you think it the true explanation?"
"I don't think it the true explanation," replied the priest placidly; "but you said that nobody could connect the four things. The true tale, of course, is something much more humdrum. Glengyle had found, or thought he had found, precious stones on his estate. Somebody had bamboozled him with those loose brilliants, saying they were found in the castle caverns. The little wheels are some diamond-cutting affair. He had to do the thing very roughly and in a small way, with the help of a few shepherds or rude fellows on these hills. Snuff is the one great luxury of such Scotch shepherds; it's the one thing with which you can bribe them. They didn't have candlesticks because they didn't want them; they held the candles in their hands when they explored the caves."
"Is that all?" asked Flambeau after a long pause. "Have we got to the dull truth at last?"
"Oh, no," said Father Brown.
As the wind died in the most distant pine woods with a long hoot as of mockery Father Brown, with an utterly impassive face, went on:
"I only suggested that because you said one could not plausibly connect snuff with clockwork or candles with bright stones. Ten false philosophies will fit the universe; ten false theories will fit Glengyle Castle. But we want the real explanation of the castle and the universe. But are there no other exhibits?"
Craven laughed, and Flambeau rose smiling to his feet and strolled down the long table.
"Items five, six, seven, etc.," he said, "and certainly more varied than instructive. A curious collection, not of lead pencils, but of the lead out of lead pencils. A senseless stick of bamboo, with the top rather splintered. It might be the instrument of the crime. Only, there isn't any crime. The only other things are a few old missals and little Catholic pictures, which the Ogilvies kept, I suppose, from the Middle Ages—their family pride being stronger than their Puritanism. We only put them in the museum because they seem curiously cut about and defaced."
The heady tempest without drove a dreadful wrack of clouds across Glengyle and threw the long room into darkness as Father Brown picked up the little illuminated pages to examine them. He spoke before the drift of darkness had passed; but it was the voice of an utterly new man.
"Mr. Craven," said he, talking like a man ten years younger, "you have got a legal warrant, haven't you, to go up and examine that grave? The sooner we do it the better, and get to the bottom of this horrible affair. If I were you I should start now."
"Now," repeated the astonished detective, "and why now?"
"Because this is serious," answered Brown; "this is not spilt snuff or loose pebbles, that might be there for a hundred reasons. There is only one reason I know of for this being done; and the reason goes down to the roots of the world. These religious pictures are not just dirtied or torn or scrawled over, which might be done in idleness or bigotry, by children or by Protestants. These have been treated very carefully—and very queerly. In every place where the great ornamented name of God comes in the old illuminations it has been elaborately taken out. The only other thing that has been removed is the halo round the head of the Child Jesus. Therefore, I say, let us get our warrant and our spade and our hatchet, and go up and break open that coffin."
"What do you mean?" demanded the London officer.
"I mean," answered the little priest, and his voice seemed to rise slightly in the roar of the gale. "I mean that the great devil of the universe may be sitting on the top tower of this castle at this moment, as big as a hundred elephants, and roaring like the Apocalypse. There is black magic somewhere at the bottom of this."
"Black magic," repeated Flambeau in a low voice, for he was too enlightened a man not to know of such things; "but what can these other things mean?"
"Oh, something damnable, I suppose," replied Brown impatiently. "How should I know? How can I guess all their mazes down below? Perhaps you can make a torture out of snuff and bamboo. Perhaps lunatics lust after wax and steel filings. Perhaps there is a maddening drug made of lead pencils! Our shortest cut to the mystery is up the hill to the grave."
His comrades hardly knew that they had obeyed and followed him till a blast of the night wind nearly flung them on their faces in the garden. Nevertheless they had obeyed him like automata; for Craven found a hatchet in his hand, and the warrant in his pocket; Flambeau was carrying the heavy spade of the strange gardener; Father Brown was carrying the little gilt book from which had been torn the name of God.
The path up the hill to the churchyard was crooked but short; only under that stress of wind it seemed laborious and long. Far as the eye could see, farther and farther as they mounted the slope, were seas beyond seas of pines, now all aslope one way under the wind. And that universal gesture seemed
