Again I examined the prostrate man, placing my hand upon his heart but failing to detect any movement. He was dead without a doubt. Noiselessly I crept forward, my ears strained to catch every sound, my hand gripping the dead man's revolver. If I were discovered I could now, at least, make a fight for life. The fearless way in which they had struck down the detective was sufficient to show me that they would hesitate at nothing. Those were exciting moments, for at the end of the narrow stone passage I passed through a door, and found myself in a great dark chamber which seemed to be unfurnished. The faint grey light that struggled in through the barred windows was sufficient to allow me to see that it opened into a great square hall, around which was set a number of ancient high-backed chairs of the same epoch as the house itself. The rooms were lined with ancient tapestries falling to decay, and there was everywhere a damp mouldy smell as though that wing of the place had long been closed and uninhabited. Passing along another corridor, I opened a door at the farther end and found myself at once in the modernised portion of the place, in a corridor where, upon the thick dark red carpet, my feet fell noiselessly, and where a candle which the intruders had probably lit was set upon a table. Again I listened. I fancied I caught the sound of voices, but was not quite certain. For some moments I remained there, holding my breath in hesitation. To search for them in that great place was full of danger and difficulty. And yet, having gone so far, I was determined that I would ascertain their object in coming there. At last, reassuring myself that the voices I had heard were only sounds in my imagination, I went forward again through an open door into a fine long picture-gallery, well carpeted as was the corridor. At the end showed another faint light, for the men had, I now saw, lit a child's night-light which they had probably brought with them. In that portion of the house there was evidence of wealth and luxury everywhere. Nardini had probably spent a good deal of the public money upon embellishing that fine old place with its wonderful sculptured fireplaces and frescoed and gilt ceilings. Still scarcely daring to breathe lest my presence be detected, I went forward again, until of a sudden voices, plain and unmistakable, broke upon my ear, causing me to halt suddenly and stand motionless as a statue. They were in some room in the vicinity. But where? It was quite dark where I stood, but from a door slightly open at some distance before me shone a thin streak of faint light, evidently from a candle. Dare I approach and peep within? At first I hesitated, for the risk was very great, but at last summoning courage I moved across the thick carpet to the open door and peered in.
