“The paper was made in Bohemia,” I said.

“Precisely. And the man who wrote the note is a German. Do you note the peculiar construction of the sentence — ‘This account of you we have from all quarters received.’ A Frenchman or Russian could not have written that. It is the German who is so uncourteous to his verbs. It only remains, therefore, to discover what is wanted by this German who writes upon Bohemian paper and prefers wearing a mask to showing his face. And here he comes, if I am not mistaken, to resolve all our doubts.”

As he spoke there was the sharp sound of horses’ hoofs and grating wheels against the curb, followed by a sharp pull at the bell. Holmes whistled.

“A pair, by the sound,” said he. “Yes,” he continued, glancing out of the window. “A nice little brougham and a pair of beauties. A hundred and fifty guineas apiece. There’s money in this case, Watson, if there is nothing else.”

“I think that I had better go, Holmes.”

“Not a bit, Doctor. Stay where you are. I am lost without my Boswell. And this promises to be interesting. It would be a pity to miss it.”

“But your client —”

“Never mind him. I may want your help, and so may he. Here he comes. Sit down in that armchair, Doctor, and give us your best attention.”

A slow and and heavy step, which had been heard upon the stairs and in the passage, paused immediately outside the door. Then there was a loud and authoritative tap.

“Come in!” said Holmes.

A man entered who could hardly have been less than six feet six inches in height, with the chest and limbs of a Hercules. His dress was rich with a richness which would, in England, be looked upon as akin to bad taste. Heavy bands of astrakhan were slashed across the sleeves and fronts of his double-breasted coat, while the deep blue cloak which was thrown over his shoulders was lined with flame-coloured silk and secured at the neck with a brooch which consisted of a single flaming beryl. Boots which extended halfway up his calves, and which were trimmed at the tops with rich brown fur, completed the impression of barbaric opulence which was suggested by his whole appearance. He carried a broad-brimmed hat in his hand, while he wore across the upper part of his face, extending down past the cheekbones, a black vizard mask, which he had apparently adjusted that very moment, for his hand was still raised to it as he entered. From the lower part of the face he appeared to be a man of strong character, with a thick, hanging lip, and a long, straight chin suggestive of resolution pushed to the length of obstinacy.

“You had my note?” he asked with a deep harsh voice and a strongly marked German accent. “I told you that I would call.” He looked from one to the other of us, as if uncertain which to address.

“Pray take a seat,” said Holmes. “This is my friend and colleague, Dr. Watson, who is occasionally good enough to help me in my cases. Whom have I the honour to address?”

He hurried forward. He wanted to make sure. He wanted relief. It was as if the power of evil had suddenly seized him and thrown him, and he wanted to say it was not so, that he had imagined it all, conjured it up. He did not want to admit the power of evil—particularly at that moment. For surely a very ugly evil spirit had struck him, in the midst of that gang of Italian soldiers. He knew it—it had pierced him. It had got him.

But he wanted to say it was not so. Reaching the house, he hastened upwards to his far–off, lonely room, through the dark corridors. Once in his own apartment, he shut the door and switched on the light, a sensation like fear at his heart. Then he searched his other pockets. He looked everywhere. In vain.

In vain, truly enough. For he knew the thing was stolen. He had known it all along. The soldiers had deliberately plotted, had deliberately rushed him and taken his purse. They must have watched him previously. They must have grinned, and jeered at him.

He sat down in a chair, to recover from the shock. The pocket–book contained four hundred francs, three one–pound notes, and various letters and private effects. Well, these were lost. But it was not so much the loss as the assault on his person that caused him to feel so stricken. He felt the jeering, gibing blows they had given as they jostled him.

And now he sat, weak in every limb, and said to himself: “Yes—and if I hadn’t rushed along so full of feeling: if I hadn’t exposed myself: if I hadn’t got worked up with the Marchesa, and then rushed all kindled through the streets, without reserve, it would never have happened. I gave myself away: and there was someone ready to snatch what I gave. I gave myself away. It is my own fault. I should have been on my guard. I should be always on my guard: always, always. With God and the devil both, I should be on my guard. Godly or devilish, I should hold fast to my reserve and keep on the watch. And if I don’t, I deserve what I get.”

But still he sat in his chair in his bedroom, dazed. One part of his soul was saying emphatically: It serves you right. It is nothing but right. It serves everybody right who rushes enkindled through the street, and trusts implicitly in mankind and in the life–spirit, as if mankind and the life–spirit were a playground for enkindled individuals. It serves you right. You have paid about twelve pounds sterling for your lesson. Fool, you might have known beforehand, and then you needn’t have paid at all. You can ill afford twelve pounds sterling, you fool. But since paid you have, then mind, mind the lesson is learned. Never again. Never expose yourself again. Never again absolute trust. It is a blasphemy against life, is absolute trust. Has a wild creature ever absolute trust? It minds itself. Sleeping or waking it is on its guard. And so must you be, or you’ll go under. Sleeping or waking, man or woman, God or the devil, keep your guard over yourself. Keep your guard over yourself, lest worse befall you. No man is robbed unless he incites a robber. No man is murdered unless he attracts a murderer. Then be not robbed: it lies within your own power. And be not murdered. Or if you are, you deserve it. Keep your guard over yourself, now, always and forever. Yes, against God quite as hard as against the devil. He’s fully as dangerous to you. . . .
