"You've seen the paper, Mr. Holmes?" he asked, holding one out to us.

"Yes, Baynes, I've seen it. Pray don't think it a liberty if I give you a word of friendly warning."

"Of warning, Mr. Holmes?"

"I have looked into this case with some care, and I am not convinced that you are on the right lines. I don't want you to commit yourself too far unless you are sure."

"You're very kind, Mr. Holmes."

"I a.s.sure you I speak for your good."

It seemed to me that something like a wink quivered for an instant over one of Mr. Baynes's tiny eyes.

"We agreed to work on our own lines, Mr. Holmes. That's what I am doing."

"Oh, very good," said Holmes. "Don't blame me."

"No, sir; I believe you mean well by me. But we all have our own systems, Mr. Holmes. You have yours, and maybe I have mine."

"Let us say no more about it."

"You're welcome always to my news. This fellow is a perfect savage, as strong as a cart-horse and as fierce as the devil. He chewed Downing's thumb nearly off before they could master him. He hardly speaks a word of English, and we can get nothing out of him but grunts."

"And you think you have evidence that he murdered his late master?"

"I didn't say so, Mr. Holmes; I didn't say so. We all have our little ways. You try yours and I will try mine. That's the agreement."

Holmes shrugged his shoulders as we walked away together. "I can't make the man out. He seems to be riding for a fall. Well, as he says, we must each try our own way and see what comes of it. But there's something in Inspector Baynes which I can't quite understand."

"Just sit down in that chair, Watson," said Sherlock Holmes when we had returned to our apartment at the Bull. "I want to put you in touch with the situation, as I may need your help to-night. Let me show you the evolution of this case so far as I have been able to follow it.

Simple as it has been in its leading features, it has none the less presented surprising difficulties in the way of an arrest. There are gaps in that direction which we have still to fill.

"We will go back to the note which was handed in to Garcia upon the evening of his death. We may put aside this idea of Baynes's that Garcia's servants were concerned in the matter. The proof of this lies in the fact that it was _he_ who had arranged for the presence of Scott Eccles, which could only have been done for the purpose of an alibi.

It was Garcia, then, who had an enterprise, and apparently a criminal enterprise, in hand that night in the course of which he met his death.

I say 'criminal' because only a man with a criminal enterprise desires to establish an alibi. Who, then, is most likely to have taken his life? Surely the person against whom the criminal enterprise was directed. So far it seems to me that we are on safe ground.

"We can now see a reason for the disappearance of Garcia's household.

They were _all_ confederates in the same unknown crime. If it came off when Garcia returned, any possible suspicion would be warded off by the Englishman's evidence, and all would be well. But the attempt was a dangerous one, and if Garcia did _not_ return by a certain hour it was probable that his own life had been sacrificed. It had been arranged, therefore, that in such a case his two subordinates were to make for some prearranged spot where they could escape investigation and be in a position afterwards to renew their attempt. That would fully explain the facts, would it not?"

The whole inexplicable tangle seemed to straighten out before me. I wondered, as I always did, how it had not been obvious to me before.

"But why should one servant return?"

"We can imagine that in the confusion of flight something precious, something which he could not bear to part with, had been left behind.

That would explain his persistence, would it not?"

"Well, what is the next step?"

"The next step is the note received by Garcia at the dinner. It indicates a confederate at the other end. Now, where was the other end? I have already shown you that it could only lie in some large house, and that the number of large houses is limited. My first days in this village were devoted to a series of walks in which in the intervals of my botanical researches I made a reconnaissance of all the large houses and an examination of the family history of the occupants.

One house, and only one, riveted my attention. It is the famous old Jacobean grange of High Gable, one mile on the farther side of Oxshott, and less than half a mile from the scene of the tragedy. The other mansions belonged to prosaic and respectable people who live far aloof from romance. But Mr. Henderson, of High Gable, was by all accounts a curious man to whom curious adventures might befall. I concentrated my attention, therefore, upon him and his household.

"A singular set of people, Watson--the man himself the most singular of them all. I managed to see him on a plausible pretext, but I seemed to read in his dark, deepset, brooding eyes that he was perfectly aware of my true business. He is a man of fifty, strong, active, with iron-gray hair, great bunched black eyebrows, the step of a deer and the air of an emperor--a fierce, masterful man, with a red-hot spirit behind his parchment face. He is either a foreigner or has lived long in the tropics, for he is yellow and sapless, but tough as whipcord. His friend and secretary, Mr. Lucas, is undoubtedly a foreigner, chocolate brown, wily, suave, and catlike, with a poisonous gentleness of speech.

You see, Watson, we have come already upon two sets of foreigners--one at Wisteria Lodge and one at High Gable--so our gaps are beginning to close.

"These two men, close and confidential friends, are the centre of the household; but there is one other person who for our immediate purpose may be even more important. Henderson has two children--girls of eleven and thirteen. Their governess is a Miss Burnet, an Englishwoman of forty or thereabouts. There is also one confidential manservant.

This little group forms the real family, for they travel about together, and Henderson is a great traveller, always on the move. It is only within the last weeks that he has returned, after a year's absence, to High Gable. I may add that he is enormously rich, and whatever his whims may be he can very easily satisfy them. For the rest, his house is full of butlers, footmen, maidservants, and the usual overfed, underworked staff of a large English country house.

"So much I learned partly from village gossip and partly from my own observation. There are no better instruments than discharged servants with a grievance, and I was lucky enough to find one. I call it luck, but it would not have come my way had I not been looking out for it.

As Baynes remarks, we all have our systems. It was my system which enabled me to find John Warner, late gardener of High Gable, sacked in a moment of temper by his imperious employer. He in turn had friends among the indoor servants who unite in their fear and dislike of their master. So I had my key to the secrets of the establishment.

"Curious people, Watson! I don't pretend to understand it all yet, but very curious people anyway. It's a double-winged house, and the servants live on one side, the family on the other. There's no link between the two save for Henderson's own servant, who serves the family's meals. Everything is carried to a certain door, which forms the one connection. Governess and children hardly go out at all, except into the garden. Henderson never by any chance walks alone.

His dark secretary is like his shadow. The gossip among the servants is that their master is terribly afraid of something. 'Sold his soul to the devil in exchange for money,' says Warner, 'and expects his creditor to come up and claim his own.' Where they came from, or who they are, n.o.body has an idea. They are very violent. Twice Henderson has lashed at folk with his dog-whip, and only his long purse and heavy compensation have kept him out of the courts.

"Well, now, Watson, let us judge the situation by this new information.

We may take it that the letter came out of this strange household and was an invitation to Garcia to carry out some attempt which had already been planned. Who wrote the note? It was someone within the citadel, and it was a woman. Who then but Miss Burnet, the governess? All our reasoning seems to point that way. At any rate, we may take it as a hypothesis and see what consequences it would entail. I may add that Miss Burnet's age and character make it certain that my first idea that there might be a love interest in our story is out of the question.

"If she wrote the note she was presumably the friend and confederate of Garcia. What, then, might she be expected to do if she heard of his death? If he met it in some nefarious enterprise her lips might be sealed. Still, in her heart, she must retain bitterness and hatred against those who had killed him and would presumably help so far as she could to have revenge upon them. Could we see her, then and try to use her? That was my first thought. But now we come to a sinister fact. Miss Burnet has not been seen by any human eye since the night of the murder. From that evening she has utterly vanished. Is she alive? Has she perhaps met her end on the same night as the friend whom she had summoned? Or is she merely a prisoner? There is the point which we still have to decide.

"You will appreciate the difficulty of the situation, Watson. There is nothing upon which we can apply for a warrant. Our whole scheme might seem fantastic if laid before a magistrate. The woman's disappearance counts for nothing, since in that extraordinary household any member of it might be invisible for a week. And yet she may at the present moment be in danger of her life. All I can do is to watch the house and leave my agent, Warner, on guard at the gates. We can't let such a situation continue. If the law can do nothing we must take the risk ourselves."

"What do you suggest?"

"I know which is her room. It is accessible from the top of an outhouse. My suggestion is that you and I go to-night and see if we can strike at the very heart of the mystery."

It was not, I must confess, a very alluring prospect. The old house with its atmosphere of murder, the singular and formidable inhabitants, the unknown dangers of the approach, and the fact that we were putting ourselves legally in a false position all combined to damp my ardour.

But there was something in the ice-cold reasoning of Holmes which made it impossible to shrink from any adventure which he might recommend.

One knew that thus, and only thus, could a solution be found. I clasped his hand in silence, and the die was cast.

But it was not destined that our investigation should have so adventurous an ending. It was about five o'clock, and the shadows of the March evening were beginning to fall, when an excited rustic rushed into our room.

"They've gone, Mr. Holmes. They went by the last train. The lady broke away, and I've got her in a cab downstairs."

"Excellent, Warner!" cried Holmes, springing to his feet. "Watson, the gaps are closing rapidly."

In the cab was a woman, half-collapsed from nervous exhaustion. She bore upon her aquiline and emaciated face the traces of some recent tragedy. Her head hung listlessly upon her breast, but as she raised it and turned her dull eyes upon us I saw that her pupils were dark dots in the centre of the broad gray iris. She was drugged with opium.

"I watched at the gate, same as you advised, Mr. Holmes," said our emissary, the discharged gardener. "When the carriage came out I followed it to the station. She was like one walking in her sleep, but when they tried to get her into the train she came to life and struggled. They pushed her into the carriage. She fought her way out again. I took her part, got her into a cab, and here we are. I shan't forget the face at the carriage window as I led her away. I'd have a short life if he had his way--the black-eyed, scowling, yellow devil."

We carried her upstairs, laid her on the sofa, and a couple of cups of the strongest coffee soon cleared her brain from the mists of the drug.

Baynes had been summoned by Holmes, and the situation rapidly explained to him.

"Why, sir, you've got me the very evidence I want," said the inspector warmly, shaking my friend by the hand. "I was on the same scent as you from the first."

"What! You were after Henderson?"

"Why, Mr. Holmes, when you were crawling in the shrubbery at High Gable I was up one of the trees in the plantation and saw you down below. It was just who would get his evidence first."

"Then why did you arrest the mulatto?"
