“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.

“It was pitch dark inside the house, and the colonel fumbled about looking for matches and muttering under his breath. Suddenly a door opened at the other end of the passage, and a long, golden bar of light shot out in our direction. It grew broader, and a woman appeared with a lamp in her hand, which she held above her head, pushing her face forward and peering at us. I could see that she was pretty, and from the gloss with which the light shone upon her dark dress I knew that it was a rich material. She spoke a few words in a foreign tongue in a tone as though asking a question, and when my companion answered in a gruff monosyllable she gave such a start that the lamp nearly fell from her hand. Colonel Stark went up to her, whispered something in her ear, and then, pushing her back into the room from whence she had come, he walked towards me again with the lamp in his hand.

“‘Perhaps you will have the kindness to wait in this room for a few minutes,’ said he, throwing open another door. It was a quiet, little, plainly furnished room, with a round table in the centre, on which several German books were scattered. Colonel Stark laid down the lamp on the top of a harmonium beside the door. ‘I shall not keep you waiting an instant,’ said he, and vanished into the darkness.

“I glanced at the books upon the table, and in spite of my ignorance of German I could see that two of them were treatises on science, the others being volumes of poetry. Then I walked across to the window, hoping that I might catch some glimpse of the country-side, but an oak shutter, heavily barred, was folded across it. It was a wonderfully silent house. There was an old clock ticking loudly somewhere in the passage, but otherwise everything was deadly still. A vague feeling of uneasiness began to steal over me. Who were these German people, and what were they doing living in this strange, out-of-the-way place? And where was the place? I was ten miles or so from Eyford, that was all I knew, but whether north, south, east, or west I had no idea. For that matter, Reading, and possibly other large towns, were within that radius, so the place might not be so secluded, after all. Yet it was quite certain, from the absolute stillness, that we were in the country. I paced up and down the room, humming a tune under my breath to keep up my spirits and feeling that I was thoroughly earning my fifty-guinea fee.

“Suddenly, without any preliminary sound in the midst of the utter stillness, the door of my room swung slowly open. The woman was standing in the aperture, the darkness of the hall behind her, the yellow light from my lamp beating upon her eager and beautiful face. I could see at a glance that she was sick with fear, and the sight sent a chill to my own heart. She held up one shaking finger to warn me to be silent, and she shot a few whispered words of broken English at me, her eyes glancing back, like those of a frightened horse, into the gloom behind her.

“‘I would go,’ said she, trying hard, as it seemed to me, to speak calmly; ‘I would go. I should not stay here. There is no good for you to do.’

“‘But, madam,’ said I, ‘I have not yet done what I came for. I cannot possibly leave until I have seen the machine.’

“‘It is not worth your while to wait,’ she went on. ‘You can pass through the door; no one hinders.’ And then, seeing that I smiled and shook my head, she suddenly threw aside her constraint and made a step forward, with her hands wrung together. ‘For the love of Heaven!’ she whispered, ‘get away from here before it is too late!’

“But I am somewhat headstrong by nature, and the more ready to engage in an affair when there is some obstacle in the way. I thought of my fifty-guinea fee, of my wearisome journey, and of the unpleasant night which seemed to be before me. Was it all to go for nothing? Why should I slink away without having carried out my commission, and without the payment which was my due? This woman might, for all I knew, be a monomaniac. With a stout bearing, therefore, though her manner had shaken me more than I cared to confess, I still shook my head and declared my intention of remaining where I was. She was about to renew her entreaties when a door slammed overhead, and the sound of several footsteps was heard upon the stairs. She listened for an instant, threw up her hands with a despairing gesture, and vanished as suddenly and as noiselessly as she had come.

“The newcomers were Colonel Lysander Stark and a short thick man with a chinchilla beard growing out of the creases of his double chin, who was introduced to me as Mr. Ferguson.

“‘This is my secretary and manager,’ said the colonel. ‘By the way, I was under the impression that I left this door shut just now. I fear that you have felt the draught.’

“‘On the contrary,’ said I, ‘I opened the door myself because I felt the room to be a little close.’

“He shot one of his suspicious looks at me. ‘Perhaps we had better proceed to business, then,’ said he. ‘Mr. Ferguson and I will take you up to see the machine.’

“‘I had better put my hat on, I suppose.’

“‘Oh, no, it is in the house.’

“‘What, you dig fuller’s-earth in the house?’

“‘No, no. This is only where we compress it. But never mind that. All we wish you to do is to examine the machine and to let us know what is wrong with it.’

“We went upstairs together, the colonel first with the lamp, the fat manager and I behind him. It was a labyrinth of an old house, with corridors, passages, narrow winding staircases, and little low doors, the thresholds of which were hollowed out by the generations who had crossed them. There were no carpets and no signs of any furniture above the ground floor, while the plaster was peeling off the walls, and the damp was breaking through in green, unhealthy blotches. I tried to put on as unconcerned an air as possible, but I had not forgotten the warnings of the lady, even though I disregarded them, and I kept a keen eye upon my two companions. Ferguson appeared to be a morose and silent man, but I could see from the little that he said that he was at least a fellow-countryman.

“Colonel Lysander Stark stopped at last before a low door, which he unlocked. Within was a small, square room, in which the three of us could hardly get at one time. Ferguson remained outside, and the colonel ushered me in.
