But it was in connexion with that that she said something I didn't understand at the time; but now I'm sure it must be as you say. She said with a sort of sudden and splendid arrogance that was entirely altruistic:
'I see part of what she meant, of course,' said Father Brown. 'What did she mean exactly by the secretary fussing about the will?'
Fiennes smiled as he answered, 'I wish you knew the secretary, Father Brown. It would be a joy to you to watch him make things hum, as he calls it. He made the house of mourning hum. He filled the funeral with all the snap and zip of the brightest sporting event. There was no holding him, after something had really happened. I've told you how he used to oversee the gardener as he did the garden, and how he instructed the lawyer in the law. Needless to say, he also instructed the surgeon in the practice of surgery; and as the surgeon was Dr Valentine, you may be sure it ended in accusing him of something worse than bad surgery. The secretary got it fixed in his red head that the doctor had committed the crime, and when the police arrived he was perfectly sublime. Need I say that he became, on the spot, the greatest of all amateur detectives? Sherlock Holmes never towered over Scotland Yard with more Titanic intellectual pride and scorn than Colonel Druce's private secretary over the police investigating Colonel Druce's death. I tell you it was a joy to see him. He strode about with an abstracted air, tossing his scarlet crest of hair and giving curt impatient replies. Of course it was his demeanour during these days that made Druce's daughter so wild with him. Of course he had a theory. It's just the sort of theory a man would have in a book; and Floyd is the sort of man who ought to be in a book. He'd be better fun and less bother in a book.'
'What was his theory?' asked the other.
'Oh, it was full of pep,' replied Fiennes gloomily. 'It would have been glorious copy if it could have held together for ten minutes longer. He said the Colonel was still alive when they found him in the summer–house, and the doctor killed him with the surgical instrument on pretence of cutting the clothes.'
'I see,' said the priest. 'I suppose he was lying flat on his face on the mud floor as a form of siesta.'
'It's wonderful what hustle will do,' continued his informant. 'I believe Floyd would have got his great theory into the papers at any rate, and perhaps had the doctor attested, when all these things were blown sky high as if by dynamite by the discovery of that dead body lying under the Rock of Fortune. And that's what we come back to after all. I suppose the suicide is almost a confession. But nobody will ever know the whole story.'
There was a silence, and then the priest said modestly: 'I rather think I know the whole story.'
Fiennes stared. 'But look here,' he cried; 'how do you come to know the whole story, or to be sure it's the true story? You've been sitting here a hundred miles away writing a sermon; do you mean to tell me you really know what happened already? If you've really come to the end, where in the world do you begin? What started you off with your own story?'
Father Brown jumped up with a very unusual excitement and his first exclamation was like an explosion.
'The dog!' he cried. 'The dog, of course! You had the whole story in your hands in the business of the dog on the beach, if you'd only noticed the dog properly.'
Fiennes stared still more. 'But you told me before that my feelings about the dog were all nonsense, and the dog had nothing to do with it.'
'The dog had everything to do with it,' said Father Brown, 'as you'd have found out if you'd only treated the dog as a dog, and not as God Almighty judging the souls of men.'
He paused in an embarrassed way for a moment, and then said, with a rather pathetic air of apology: 'The truth is, I happen to be awfully fond of dogs. And it seemed to me that in all this lurid halo of dog superstitions nobody was really thinking about the poor dog at all. To begin with a small point, about his barking at the lawyer or growling at the secretary. You asked how I could guess things a hundred miles away; but honestly it's mostly to your credit, for you described people so well that I know the types. A man like Traill, who frowns usually and smiles suddenly, a man who fiddles with things, especially at his throat, is a nervous, easily embarrassed man. I shouldn't wonder if Floyd, the efficient secretary, is nervy and jumpy, too; those Yankee hustlers often are. Otherwise he wouldn't have cut his fingers on the shears and dropped them when he heard Janet Druce scream.
'Now dogs hate nervous people. I don't know whether they make the dog nervous, too; or whether, being after all a brute, he is a bit of a bully; or whether his canine vanity (which is colossal) is simply offended at not being liked. But anyhow there was nothing in poor Nox protesting against those people, except that he disliked them for being afraid of him. Now I know you're awfully clever, and nobody of sense sneers at cleverness. But I sometimes fancy, for instance, that you are too clever to understand animals. Sometimes you are too clever to understand men, especially when they act almost as simply as animals. Animals are very literal; they live in a world of truisms. Take this case: a dog barks at a man and a man runs away from a dog. Now you do not seem to be quite simple enough to see the fact: that the dog barked because he disliked the man and the man fled because he was frightened of the dog. They had no other motives and they needed none; but you must read psychological mysteries into it and suppose the dog had super–normal vision, and was a mysterious mouthpiece of doom. You must suppose the man was running away, not from the dog but from the hangman. And yet, if you come to think if it, all this deeper psychology is exceedingly improbable. If the dog really could completely and consciously realize the murderer of his master he wouldn't stand yapping as he might at a curate at a tea–party; he's much more likely to fly at his throat. And on the other hand, do you really think a man who had hardened his heart to murder an old friend and then walk about smiling at the old friend's family, under the eyes of his old friend's daughter and post– mortem doctor–do you think a man like that would be doubled up by mere remorse because a dog barked? He might feel the tragic irony of it; it might shake his soul, like any other tragic trifle. But he wouldn't rush madly the length of a garden to escape from the only witness whom he knew to be unable to talk. People have a panic like that when they are frightened, not of tragic ironies, but of teeth. The whole thing is simpler than you can understand.
'But when we come to that business by the seashore, things are much more interesting. As you stated them, they were much more puzzling. I didn't understand that tale of the dog going in and out of the water; it didn't seem to me a doggy thing to do. If Nox had been very much upset about something else, he might possibly have refused to go after the stick at all. He'd probably go off nosing in whatever direction he suspected the mischief. But when once a dog is actually chasing a thing, a stone or a stick or a rabbit, my experience is that he won't stop for anything but the most peremptory command, and not always for that. That he should turn round because his mood changed seems to me unthinkable.'
'But he did turn round,' insisted Fiennes; 'and came back without the stick.'
'He came back without the stick for the best reason in the world,' replied the priest. 'He came back because he couldn't find it. He whined because be couldn't find it. That's the sort of thing a dog really does whine about. A dog is a devil of a ritualist. He is as particular about the precise routine of a game as a child about the precise repetition of a fairy–tale. In this case something had gone wrong with the game. He came back to complain seriously of the conduct of the stick. Never had such a thing happened before. Never had an eminent and distinguished dog been so treated by a rotten old walking–stick.'
'Why, what had the walking–stick done?' inquired the young man.
'It had sunk,' said Father Brown.
Fiennes said nothing, but continued to stare; and it was the priest who continued: 'It had sunk because it was not really a stick, but a rod of steel with a very thin shell of cane and a sharp point. In other words, it was a sword stick. I suppose a murderer never gets rid of a bloody weapon so oddly and yet so naturally as by throwing it into the sea for a retriever.'
'I begin to see what you mean,' admitted Fiennes;' but even if a sword–stick was used, I have no guess of how it was used.'
'I had a sort of guess,' said Father Brown, 'right at the beginning when you said the word summer–house. And another when you said that Druce wore a white coat. As long as everybody was looking for a short dagger, nobody thought of it; but if we admit a rather long blade like a rapier, it's not so impossible.'
He was leaning back, looking at the ceiling, and began like one going back to his own first thoughts and fundamentals.
'All that discussion about detective stories like the Yellow Room, about a man found dead in sealed chambers
