Whilst Don Miguel was preparing for the fight, a slight sound suddenly caused him to turn towards that side of the room, from whence a tall oaken door led to his own and the Cardinal's apartments. His eyes, rendered peculiarly keen by the imminence of his own danger, quickly perceived a thin fillet of artificial light running upwards from the floor, which at once suggested to him that the door was slightly ajar.
It had certainly been closed when Wessex first entered the room. Behind it, as Don Miguel well knew, the Cardinal de Moreno had been watching; he was the great stage-manager of the drama which he had contrived should be enacted this night before His Grace. The young Marquis was only one of the chief actors; the principal actress being the wench Mirrab, who, surfeited with wine, impatient and violent, had been kept a close prisoner by His Eminence these last six hours past.
That little glimmer of light dispelled Don Miguel's strange obsession. The Cardinal, with the slight opening of that door, had plainly meant to indicate that he was on the alert, and that this unrehearsed scene of the drama would not be enacted without his interference. The Duke, who had his back to that portion of the room, had evidently seen and heard nothing, and the whole little episode had occurred in less than three seconds.
Now Don Miguel was ready, and the next moment the swords clashed against one another. Eye to eye these two enemies seemed to gauge one another's strength. For a moment their daggers, held in the left hand, only acted as weapons of defence, the cloaks wrapped round their arms were still efficient sheaths.
Very soon the Spaniard realized that his original fears had not been exaggerated. Wessex was a formidable opponent, absolutely calm, a skilful fencer, and with a wrist which seemed made of steel. His attack was quick and vigorous; step by step, slowly but unerringly, he forced the Marquis away from the stronghold of his position. Try how he might, parry how he could, the young Spaniard gradually found himself thrust more and more into full light, whilst his antagonist was equally steadily working his way round towards the more advantageous post.
No sound came from the Cardinal's apartments, and Don Miguel dared not even glance towards the door, for the swiftest look would have proved his undoing.
Wessex' face was like a mask, quite impassive, almost stony in its rigid expression of perfect determination. The Spaniard was still steadily losing ground, another few minutes and he would be in full light, whilst the Duke's figure would become the deceptive silhouette. Under those conditions, and against such a perfect swordsman, the Marquis knew that his doom was sealed. An icy sweat broke out from his forehead, he would have bartered half his fortune to know what was going on behind the door.
For one awful moment the thought crossed his mind that His Eminence perhaps had decreed his death at the hands of Wessex. Who knows? the ways of diplomacy are oft tortuous and ever cruel; none knew that better than Don Miguel de Suarez himself. How oft had he callously exercised the right given him by virtue of some important mission entrusted to him, in order to sweep ruthlessly aside the lesser pawns which stood in the way of his success?
Had he become the lesser pawn now in this gigantic game of chess, in which the hand of a Queen was the final prize for the victor? Was his death, at the hand of this man, of more importance to the success of the Cardinal's intrigues than his life would be? If so, Heaven alone could help him, for His Eminence would not hesitate to sacrifice him mercilessly.
The horror of these thoughts gave the young man the strength of despair. But he might just as well have tried to pierce a stone wall, as to break the garde of this impassive and deadly opponent. His own wrist was beginning to tire; the combat had lasted nigh on a quarter of an hour, and the next few minutes would inevitably see its fatal issue. The Duke's attacks became more swift and violent; once or twice already Don Miguel had all but felt His Grace's dagger at his throat.
