The obstacle to the scheme was, of course, the possibility that my house might be in the possession of Kolfort’s agents, and that I might run my head into a trap. But the house contained so many secret ways and passages that this risk was greatly lessened; and I reckoned that I could at least effect an entrance without being discovered, and if I found the project impossible could leave it again. In any case, the possession of the plan of route was so essential to me under the circumstances that I made up my mind to run the risk of the venture.

I had first to find my way to the city, however, and in this I was singularly fortunate. I had ridden some three or four hours when the moon rose, and soon afterwards, to my intense satisfaction, my cross road came out at a point which I recognised as being some four or five miles from my house. I quickened my pace, therefore, riding very warily, and, wherever possible, cantering on the turf, until I came out on the heath which was close to the mouth of the underground passage leading under my grounds. I would not trust myself to use that because its secret was known to Kolfort’s agents; but I chose a path which led me to another gate of the garden.

I dismounted there, unlocked the gate, drew my horse under the shadow of some trees, fastened him, and, thrusting the revolver into my belt for use in case of need, crept forward to reconnoitre the house.

Every window at the back was in darkness, even to the kitchens, and the place seemed empty and deserted. Keeping well within the shadow of the walls, I stole round with the utmost caution to the front, taking care that every footfall should be deadened by either the turf or the soft mould of the flower beds.

In the front there was a faint light from one window; a carriage stood in the roadway, and, near the gates opening from the drive, I saw one or two moving shadows of men.

The carriage surprised and startled me. Obviously someone was taking a keen interest in my concerns, and was inside the house; and I had to consider whether I dared to venture any further with my plan in the face of such added danger. A minute’s thought determined me to proceed, however. What I had feared was the presence of a fairly large number of men holding possession of the house; but there was no sign of this, and if only one or two attendants were with this visitor, whoever it might be, they would not have an easy task to capture me, while I should not have a difficult one to avoid them.

At the side where I stood there was a small opening into a passage that led straight to my library, and, unlocking it very softly, I entered, and stole along it on tiptoe, feeling my way by the wall in the pitchy darkness. There were several doors leading off from the narrow passage to different parts of the house, and at each of these I stood and listened intently, venturing to unlock one or two of them with my master-key. In this way I was able to satisfy myself that not a soul was in the lower part of the house, and, assured by this knowledge, I crept up the stone staircase that led to the library.

The need for absolute silence on my part increased with every step, and when I reached the top I drew off my heaving riding boots and moved at a snail’s pace, my stockinged feet making no noise whatever.

The entrance to the passage from the room had been masked very cleverly. It was formed by a revolving panel in the wall, which swung on well-oiled pivots and opened behind a sham cabinet, through the painted glass doors of which care had been taken to allow of anyone who stood in the cabinet both hearing and seeing all that went on in the room. I moved the panel inch by inch with infinite care and caution, and as I did so heard the sound of voices.

I started, and almost lost my presence of mind as I recognised the deep, gruff tone of General Kolfort, followed by the soft, dulcet, seductive laugh of the Countess Bokara. Passing noiselessly through the panel, I entered the cabinet, and the sight that met my eyes made me almost cry out in astonishment.
