Holmes examined it with interest. "Where did you get it?"
"There is a central heating furnace in the cellar under Lady Beatrice's room. It's been off for some time, but Sir Robert complained of cold and had it on again. Harvey runs it he's one of my lads. This very morning he came to me with this which he found raking out the cinders. He didn't like the look of it."
"Nor do I," said Holmes. "What do you make of it, Watson?"
It was burned to a black cinder, but there could be no question as to its anatomical significance. "It's the upper condyle of a human femur," said I.
"Exactly!" Holmes had become very serious. "When does this lad tend to the furnace?"
"He makes it up every evening and then leaves it."
"Then anyone could visit it during the night?"
"Yes, sir."
"Can you enter it from outside?"
"There is one door from outside. There is another which leads up by a stair to the passage in which Lady Beatrice's room is situated."
"These are deep waters, Mr. Mason; deep and rather dirty. You say that Sir Robert was not at home last night?"
"No, sir."
"Then, whoever was burning bones, it was not he."
"That's true,sir"
"What is the name of that inn you spoke of?"
"The Green Dragon."
"Is there good fishing in that part of Berkshire?"
The honest trainer showed very clearly upon his face that he was convinced that yet another lunatic had come into his harassed life. "Well, sir, I've heard there are trout in the millstream and pike in the Hall lake."
"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 tonight. 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 neighborhood.
"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 tonight,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 colorless, uneventful case which is hopeless.
"Let us consider our data. The brother no longer visits the beloved invalid sister. He gives away her favorite 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 favorite horse and apparently takes to drink. That covers the case, does it not?"
"Save for the business in the crypt."
"That is another line of thought. There are two, and I beg you will not tangle them. Line A, which concerns Lady Beatrice, has a vaguely sinister flavor, has it not?"
"I can make nothing of it."
"Well, now, let us take up line B, which concerns Sir Robert. He is mad keen upon winning the Derby. He is in the hands of the Jews, and may at any moment be sold up and his racing stables seized by his creditors. He is a daring and desperate man. He derives his income from his sister. His sister's maid is his willing tool. So far we seem to be on fairly safe ground, do we not?"
"But the crypt?"
"Ah, yes, the crypt! Let us suppose, Watson it is merely a scandalous supposition, a hypothesis put forward for argument's sake that Sir Robert has done away with his sister."
"My dear Holmes, it is out of the question."
"Very possibly, Watson. Sir Robert is a man of an honorable stock. But you do occasionally find a carrion crow among the eagles. Let us for a moment argue upon this supposition. He could not fly the country until he had realized his fortune, and that fortune could only be realized by bringing off this coup with Shoscombe Prince. Therefore, he has still to stand his ground. To do this he would have to dispose of the body of his victim, and he would also have to find a substitute who would impersonate her. With the maid as his confidante that would not be impossible. The woman's body might be conveyed to the crypt, which is a place so seldom visited, and it might be secretly destroyed at night in the furnace, leaving behind it such evidence as we have already seen. What say you to that, Watson?"
"Well, it is all possible if you grant the original monstrous supposition."
"I think that there is a small experiment which we may try tomorrow, Watson, in order to throw some light on the matter. Meanwhile, if we mean to keep up our characters, I suggest that we have our host in for a glass of his own wine and hold some high converse upon eels and dace, which seems to be the straight road to his affections. We may chance to come upon some useful local gossip in the process."
In the morning Holmes discovered that we had come without our spoon-bait for jack, which absolved us from fishing for the day. About eleven o'clock we started for a walk, and he obtained leave to take the black spaniel with us.
