The Secret of the Villa Verde.

The unexpected sight that met my eyes within that narrow stone passage was truly horrifying.

An oil lamp shed a faint light at the farther end of the narrow tunnel-like place, and revealed the body of a man lying in a heap in such a position that I saw, in an instant, that some tragedy had occurred.

Creeping forward I bent beside him and touched his hand. It was still warm, yet I saw across the stones a large dark pool—a pool of blood, and at the same moment discovered that it issued from an ugly knife-wound just over the heart.

He was a respectably dressed man of forty, robust, heavily built, with dark moustache and shaven chin. As I touched his hand, which lay helpless at his side, my fingers came into contact with something hard, and I found that strapped around his waist he carried a revolver.

Quickly I took it out, for I had no weapon myself, and at a glance saw that it was the regulation pattern as supplied to the agents of police.

The man who had been stabbed to the heart so unerringly was probably a detective who had been left in charge of the villa after the police had taken possession of the place. Hearing a summons at the door he had perhaps gone to open it, when the ready knife had struck him down, and the desperate trio had passed over his body and entered the villa to prosecute their mysterious object.

I listened. There was no sound. The intruders, whatever their object, were in the main building; for it seemed that this narrow passage merely gave entrance to the servants’ quarters. The place was an enormous, rambling one, built, as I afterwards found, by Prince Torlonia in the days of the Borgia Pope, once full of splendour and magnificence, but sadly neglected and degenerated in these modern days.

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.

It was a great salon, I found, a huge, high-roofed place with old gilt furniture upholstered in red silk brocade and some marvellous buhl cabinets full of rare china and bric-à-brac. The place was in darkness, save for the single night-light placed upon a chair—the intruders fearing, of course, to ignite the lamps as the light would shine outside and perhaps attract attention.

The great salon led into an inner room, and in there I saw their moving figures by the light of two candles that had been put upon the carpet. They were conversing only in low whispers and seemed to be groping about the floor in the farther corner of the room, as though in search of something.

I slipped into the big salon, and creeping from table to chair, bending do............
