“‘I quite follow you,’ said I. ‘The only point which I could not quite understand was what use you could make of a hydraulic press in excavating fuller’s-earth, which, as I understand, is dug out like gravel from a pit.’

“‘Ah!’ said he carelessly, ‘we have our own process. We compress the earth into bricks, so as to remove them without revealing what they are. But that is a mere detail. I have taken you fully into my confidence now, Mr. Hatherley, and I have shown you how I trust you.’ He rose as he spoke. ‘I shall expect you, then, at Eyford at 11:15.’

“‘I shall certainly be there.’

“‘And not a word to a soul.’ He looked at me with a last long, questioning gaze, and then, pressing my hand in a cold, dank grasp, he hurried from the room.

“Well, when I came to think it all over in cool blood I was very much astonished, as you may both think, at this sudden commission which had been intrusted to me. On the one hand, of course, I was glad, for the fee was at least tenfold what I should have asked had I set a price upon my own services, and it was possible that this order might lead to other ones. On the other hand, the face and manner of my patron had made an unpleasant impression upon me, and I could not think that his explanation of the fuller’s-earth was sufficient to explain the necessity for my coming at midnight, and his extreme anxiety lest I should tell anyone of my errand. However, I threw all fears to to the winds, ate a hearty supper, drove to Paddington, and started off, having obeyed to the letter the injunction as to holding my tongue.

“At Reading I had to change not only my carriage but my station. However, I was in time for the last train to Eyford, and I reached the little dim-lit station after eleven o’clock. I was the only passenger who got out there, and there was no one upon the platform save a single sleepy porter with a lantern. As I passed out through the wicket gate, however, I found my acquaintance of the morning waiting in the shadow upon the other side. Without a word he grasped my arm and hurried me into a carriage, the door of which was standing open. He drew up the windows on either side, tapped on the wood-work, and away we went as fast as the horse could go.”

“One horse?” interjected Holmes.

“Yes, only one.”

“Did you observe the colour?”

“Yes, I saw it by the side-lights when I was stepping into the carriage. It was a chestnut.”

“Tired-looking or fresh?”

“Oh, fresh and glossy.”

“Thank you. I am sorry to have interrupted you. Pray continue your most interesting statement.”

“Away we went then, and we drove for at least an hour. Colonel Lysander Stark had said that it was only seven miles, but I should think, from the rate that we seemed to go, and from the time that we took, that it must have been nearer twelve. He sat at my side in silence all the time, and I was aware, more than once when I glanced in his direction, that he was looking at me with great intensity. The country roads seem to be not very good in that part of the world, for we lurched and jolted terribly. I tried to look out of the windows to see something of where we were, but they were made of frosted glass, and I could make out nothing save the occasional bright blur of a passing light. Now and then I hazarded some remark to break the monotony of the journey, but the colonel answered only in monosyllables, and the conversation soon flagged. At last, however, the bumping of the road was exchanged for the crisp smoothness of a gravel-drive, and the carriage came to a stand. Colonel Lysander Stark sprang out, and, as I followed after him, pulled me swiftly into a porch which gaped in front of us. We stepped, as it were, right out of the carriage and into the hall, so that I failed to catch the most fleeting glance of the front of the house. The instant that I had crossed the threshold the door slammed heavily behind us, and I heard faintly the rattle of the wheels as the carriage drove away.

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. . . .
