"I yielded to your accursed temptation, it is true!" I cried fiercely.

"But human feeling is not entirely dead in my heart, as it is in yours.

Thank G.o.d that my hands are still unsullied!"

He laughed--the same harsh, discordant laugh that had escaped him when, below in the library, I had refused to accept the vile condition of the compact.

He stood there barring my pa.s.sage to that room wherein lay the unknown woman who had been so strangely united to me. Whoever she was, I was resolved to rescue her. Mystery surrounded her--mystery that I resolved at all hazards to penetrate.

"You were in want of money, and I offered it to you," the Tempter answered coldly. "You have refused, and the matter is ended."

"I think not," I said warmly. "You will hear something more of this night's work."

He laughed again, displaying an uneven row of discoloured teeth. To argue with him further was useless.

"Come, stand aside?" I cried, making a movement forward.

He receded a couple of paces, until he stood with his back against the door, and as I faced him I looked down the shining barrel of a revolver.

I do not know what possessed me at that instant. I did not fully realise my danger, that is certain. My mind was too full of the mystery surrounding the unknown woman who was lying within, and whose hand had showed me that she was no invalid. Physically I am a muscular man, and without a second's hesitation I sprang upon my adversary and closed with him. His strength was marvellous. I had under-calculated it, for he was wiry, with muscles like iron.

For a few moments we swayed to and fro in deadly embrace, until I felt that he had turned the weapon until the barrel touched my neck. Next instant there was a loud report. The flash burned my face, but fortunately the bullet only grazed my cheek.

I was unharmed, but his deliberate attempt to take my life urged me to desperation, and with an almost superhuman effort I tripped him by a trick, and kneeling upon him, wrenched the weapon from his grasp. Then, leaving him, I dashed towards the door and turned the handle, but in vain. It was locked. Without more ado I stepped back, and taking a run, flung myself against the door, bursting the lock from its socket and falling headlong into the chamber.

The light was insufficient in that great chamber; therefore I drew up one of the blinds partially and crossed to the bed, full of curiosity.

My wife was lying there, silent and still. Her wealth of dishevelled hair strayed across the lace-edged pillow, and the hand with the wedding-ring I had placed upon it was raised above her head and tightly clenched in that att.i.tude often a.s.sumed by children in their sleep.

She had screamed. That sound I had heard, so shrill and plain, was undoubtedly the voice of a young woman, and it had come from this room, which was directly above the library. Yet, as far as I could see, there was nothing to indicate the cause of her alarm.

Utterly bewildered, I stood there gazing at the form hidden beneath the silken coverlet of pale blue. The face was turned away towards the wall, so that I could not see it.

Why, I wondered, had the Tempter barred my entrance there with such determination, endeavouring to take my life rather than allow me to enter there?

The small ormolu clock chimed the hour upon its silver bell. It was one o'clock.

Attentively I bent and listened. Her breathing seemed very low. I touched her hand and found it chilly.

For a moment I hesitated to disturb her, for she was lying in such a position that I could not see her face without turning her over.

Suddenly, however, it occurred to me that I might draw out the bed from the wall and get behind it.

This I did, but the bed, being very heavy, required all my effort to move it.

Strangely enough at that moment I felt a curious sensation in my mouth and throat, and an unaccountable dizziness seized me. It seemed as though my mouth and lips were swelling, and the thought occurred to me that I might have ruptured a blood-vessel in my exertions in moving the bed.

Eager, however, to look upon the face of the woman who was my wife, I slipped between the wall and the bed, and, bending down, drew back the embroidered sheet which half concealed the features.

I stood dumb-stricken. The face was the most beautiful, the most perfect in contour and in natural sweetness of expression, that I had ever gazed upon. It was the face of a healthful and vigorous girl of twenty, rather than of an invalid--a face about the beauty of which there could be no two opinions. The great blue eyes were wide open, looking curiously into mine, while about the mouth was a half-smile which rendered the features additionally attractive.

"You are ill," I whispered in a low, intense voice, bending to her.

"Cannot you tell me what is the matter? I am a doctor, and will do all in my power to make you better."

There was no response. The great blue eyes stared at me fixedly, the smile did not relax, the features seemed strangely rigid. Next second a terrible suspicion flashed across my mind, and I bent closer down. The eyes did not waver in the light as eyes must do when a light shines straight into them. I touched her cheek with my hand, and its thrilling contact told me the truth only too plainly.

My wife was dead. She had died before sunset, as the Tempter had intended.

The discovery held me immovable. Hers was a face such as I had never seen before. She was a woman before whom, had I met her in life, I should have fallen down and worshipped. Indeed, strange as it may seem, I confess that, as I stood there, I fell in love with her--even though she was a corpse.

Yet, as my eyes fixed themselves lovingly upon her features, as sweet, tender, and innocent in expression as a child's, I could not imagine the cause of death. There was no sign of disease or unhealthiness there.

Why had she uttered those screams? Why, indeed, had the door of the death-chamber been afterwards locked? Had she, after all, fallen a victim to foul play?

I drew down the bed-clothes and exposed her neck in order to make an examination. She wore, suspended by a thin gold chain, a small amulet shaped like a note of interrogation and encrusted with diamonds. My observations told me that she had not worn it very long, for the edges of the stones were sharp, yet the delicate skin remained unscratched. A desire possessed me to have some souvenir of her, and without further ado, I unclasped the chain from her neck, and placed it and the little charm in my pocket.

Then, in continuation of my examination, I placed my hand upon her heart, but could detect no cause of death.

Upon her breast, however, I found a curious tattoo-mark--a strange device representing three hearts entwined. Now in my medical experience, I have found that very few women are tattooed. A woman usually shrinks from the operation--which is not unaccompanied by pain-- and, on careful examination of this mark, I came to the conclusion that it had been p.r.i.c.ked some years ago by a practised hand; further, that it had some distinct and mysterious signification.

It was in the exact centre of the breast, and just sufficiently low to remain concealed when she had worn a _decollete_ dress. The light was dim and unsatisfactory, but all my efforts to trace the hand of an a.s.sa.s.sin were futile.

Suddenly, however, as I examined her eyes, the left one, nearest the pillow, bore an expression which struck me as unusual. Both organs of sight seemed to have lost their clearness in the moments I had been standing there, and were glazing as _rigor mortis_ set in, but the left eye was becoming more blurred than its fellow--an unusual circ.u.mstance which attracted me. The bright blue which I had seen in its unfathomable depths had contracted in a manner altogether unaccountable until it was now only the size of a pin's head. I bent again closely and peered into it. Next instant the awful truth was revealed.

She had been foully murdered.

With quick heart-beating I examined the eye carefully, finding symptoms of death from some deliriant--a neurotic acting on the brain and producing delirium, presbyopia, and coma. Certain it was that if this were actually the Tempter's work, he was a veritable artist in crime, for the manner in which death had been caused was extremely difficult to determine.

Finding myself undisturbed there, I made further and more searching examination, until I held the opinion that death must have been almost, if not quite, instantaneous.

But such theory did not coincide with the screams that had escaped her.

On reviewing the whole of the circ.u.mstances, I felt confident that she must have been fully conscious at the time, and that those shrieks were shrieks of terror. She had divined the intention of her enemies.

About the vicinity of the bed I searched for any bottle of medicine that might be there, but in vain. If she had really been ill previously, as the Tempter had alleged, the medicine prescribed might give me some clue to the nature of her disease.

Upon a chair close by, her bridal veil of Brussels lace was lying crumpled in a heap, while her gown of white satin was hanging upon the door-k.n.o.b of the handsome wardrobe. The orange-blossoms diffused their perfume over the room, but to me it was a sickly odour emblematic of the grave.

My wife, the most beautiful woman upon whom my eyes had ever fallen, was lifeless--struck down by the hand of a murderer.

As I bent, looking full into the contracted pupil, I suddenly detected something half concealed in the lace edging of the pillow. I drew it forth, and found it to be a crumpled letter, which I spread out and read. It had evidently been treasured there, just as invalids treasure beneath the bolster all the correspondence they receive.

In an angular hand, evidently masculine, was written the simple words, without address or signature, "I have seen La Gioia!"

Who, I wondered, was "La Gioia"? Was it a happy meeting or a disconcerting one? The announcement was bare enough, without comment and without detail. Significant, no doubt, it had been received by her and kept secret beneath her pillow.

I started across the room to investigate my dead wife's surroundings and to learn, if possible, by observation, something concerning her life. A room is often indicative of a woman's character, and always of her habits. The apartment was, I found, artistic and luxurious, while the few books lying about showed her to be a woman of education, culture, and refinement. Upon a little side-table, concealed behind a pile of books, I found a small blue bottle which, taking up, I held to the light, and afterwards uncorked and smelt, wondering whether its odour would give me any clue to its composition. The bottle contained pure chloroform.

Once more I crossed to the bed when, of a sudden, I again felt that strange sensation in my mouth and throat, both of which seemed to contract until my breathing became difficult. I felt half strangled. I fought against the curious feeling that crept over me, but a dizziness seized me, and I was compelled to clutch the foot of the bed in order to steady myself.

My mouth was burning, my head reeling, while my lower limbs seemed to have, in that moment, become cold, benumbed, and devoid of all feeling.

I held my breath, determined to battle against the faintness; but all was useless. Sharp, acute pains shot through my legs as though red-hot wires were being thrust through my muscles, and a second later I became seized by a kind of paralysis which held my jaws immovable.
