The Classic Mystery Collection - Arthur Conan Doyle [355]
'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.'

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 which no one could enter, does not apply to the present case, because it is a summer - house. When we talk of a Yellow Room, or any room, we imply walls that are really homogeneous and impenetrable. But a summer - house is not made like that; it is often made,
