“That’s good enough. Watson and I are famous fishermen - are we not, Watson? You may address us in future at the Green Dragon. We should reach it to-night. I need not say that we don’t want to see you, Mr. Mason, but a note will reach us, and no doubt I could find you if I want you. When we have gone a little farther into the matter I will let you have a considered opinion.”

Thus it was that on a bright May evening Holmes and I found ourselves alone in a first-class carriage and bound for the little “halt-on-demand” station of Shoscombe. The rack above us was covered with a formidable litter of rods, reels, and baskets. On reaching our destination a short drive took us to an old-fashioned tavern, where a sporting host, Josiah Barnes, entered eagerly into our plans for the extirpation of the fish of the neighbourhood.

“What about the Hall lake and the chance of a pike?” said Holmes.

The face of the innkeeper clouded.

“That wouldn’t do, sir. You might chance to find yourself in the lake before you were through.”

“How’s that, then?”

“It’s Sir Robert, sir. He’s terrible jealous of touts. If you two strangers were as near his training quarters as that he’d be after you as sure as fate. He ain’t taking no chances, Sir Robert ain’t.”

“I’ve heard he has a horse entered for the Derby.”

“Yes, and a good colt, too. He carries all our money for the race, and all Sir Robert’s into the bargain. By the way” - he looked at us with thoughtful eyes - “I suppose you ain’t on the turf yourselves?”

“No, indeed. Just two weary Londoners who badly need some good Berkshire air.”

“Well, you are in the right place for that. There is a deal of it lying about. But mind what I have told you about Sir Robert. He’s the sort that strikes first and speaks afterwards. Keep clear of the park.”

“Surely, Mr. Barnes! We certainly shall. By the way, that was a most beautiful spaniel that was whining in the hall.”

“I should say it was. That was the real Shoscombe breed. There ain’t a better in England.”

“I am a dog-fancier myself,” said Holmes. “Now, if it is a fair question, what would a prize dog like that cost?”

“More than I could pay, sir. It was Sir Robert himself who gave me this one. That’s why I have to keep it on a lead. It would be off to the Hall in a jiffy if I gave it its head.”

“We are getting some cards in our hand, Watson,” said Holmes when the landlord had left us. “It’s not an easy one to play, but we may see our way in a day or two. By the way, Sir Robert is still in London, I hear. We might, perhaps, enter the sacred domain to-night without fear of bodily assault. There are one or two points on which I should like reassurance.”

“Have you any theory, Holmes?”

“Only this, Watson, that something happened a week or so ago which has cut deep into the life of the Shoscombe household. What is that something? We can only guess at it from its effects. They seem to be of a curiously mixed character. But that should surely help us. It is only the colourless, uneventful case which is hopeless.

“Let us consider our data. The brother no longer visits the beloved invalid sister. He gives away her favourite dog. Her dog, Watson! Does that suggest nothing to you?”

“Nothing but the brother’s spite.”

“Well, it might be so. Or - well, there is an alternative. Now to continue our review of the situation from the time that the quarrel, if there is a quarrel, began. The lady keeps her room, alters her habits, is not seen save when she drives out with her maid, refuses to stop at the stables to greet her favourite horse, and apparently takes to drink. That covers the case, does it not?”

“Save for the business in the crypt.”
