and terror-filled at this unexpected check to his manoeuvre, pushing along for dear life.
It had been such a splendid scheme, evolved over there in the lonely mill on the Veluwe, between a reprobate and a traitor. The Spaniards on the watch. The Stadtholder helpless, whilst his mount carried him headlong into their hands. What a triumph for Stoutenburg, who had planned it all, and for Nicolaes Beresteyn, the worker of the infamous plot! The Stadtholder prisoner in the hands of the Archduchess! His life the price of the subjection of the Netherlands!
And all to be frustrated by a foolish mischance! Three riders intent upon intercepting that runaway horse! Who in thunder were they? The mist, remember, would have blurred Nicolaes' vision. His thoughts were not just then on the man whom he hated. They were fixed upon the possibility -- remote, alas! -- of convincing the Stadtholder after this that the goaded horse had been the victim of a series of accidents.
Even at this moment the foremost of the three riders had overtaken the runaway. He galloped for a length or two beside it, then, with a dexterous and unerring grip, he seized the panic-stricken animal by the bridle. A few seconds of desperate struggle 'twixt man and beast. Then man remained the conqueror. The horse, panting, quivering in every limb, covered in sweat and foam, was finally brought to a standstill, and the Stadtholder in an instant had his feet clear of the stirrups and swung himself out of the saddle.

Then, and then only, did Nicolaes Beresteyn recognize the man who for the second time had frustrated his nefarious plans -- the man whom, because of his easy triumphs, the humiliation which he had inflicted upon him, because of his careless gaiety and his very joy of life, he hated with a curious, sinister intensity.
A ferocious imprecation rose to his lips. For awhile everything became a blank. The present, the future, even the past. Everything became chaos in his mind, he could no longer think. All that he had planned became a blur, as if the sea-fog had enveloped his senses as well as the entire landscape.
But this confused mental state only lasted a very little while -- a few seconds perhaps. Slowly, while he gazed on that distant group of men and horses, his perceptions became clearer once more. And even before the imprecation had died on his lips it gave place to a smile of triumph. Nicolaes Beresteyn had remembered that his Majesty the devil might well be trusted to care for his own. Had he not served the hell-born liege lord well?
For the nonce he brought his horse to a halt. It would be worse than folly to go on. With recognition of those three horsemen over there had also come the certainty that he was now irretrievably unmasked. The Stadtholder, his father, his sister, even his young wife, would turn from him in horror, as from a traitor and an outcast -- a pariah, marked with the brand of Cain.
No! Henceforth, for good or for evil, his fortunes must be linked openly with Stoutenburg -- with the man who wielded such a strange cabalistic power over him that he (Nicolaes) -- rich, newly wed, in a highly enviable worldly position -- had been ready to sacrifice his all in his cause, and to throw in the last shred of his honour into the bargain. In Stoutenburg's cause -- ay, and in order to be revenged on the man who had never wronged him save in his conceit -- that most vulnerable spot in the moral armour of such contemptible rogues as was Nicolaes Beresteyn.
The spot where he had brought his horse to a halt was immediately behind a low, deserted hut, which concealed him from view. Here he dismounted and, throwing the reins over his arm, advanced cautiously to a point of vantage at the angle of the little building, whence he could see what those four men were doing over there but himself remain unseen.
They, too, had dismounted, and were obviously intent on examining the Stadtholder's horse. A sinister scowl spread over Nicolaes Beresteyn's face. There was still a chance, then, of putting a bullet in one or other of those two men -- the hated enemy or the Stadtholder. Nicolaes pondered; the scowl on his face became almost satanic in its expression of cruelty. Awhile ago, he had replaced his pistol in the holster, after it had served its nefarious purpose. Now he took it out again and examined it thoroughly.
It had one more charge in it, the devilish charge invented by the Borgias, the secret of which one of that infamous race had confided to Stoutenburg. The fumes from the powder when it struck the eyes must cause irretrievable blindness. Indeed, it had proved its worth already.
Nicolaes, from his hiding-place, could see those four men quite clearly. The Stadtholder, Diogenes, the two caitiffs, all standing round the one horse. Then Diogenes took something out of his belt. He raised his arm, and the next moment a sharp report rang through the mistladen air. The poor animal rolled over instantly into the mud.
The scowl on Nicolaes' face now gave place once more to a smile of triumph -- more sinister than the frown. With the gesture of a conqueror, he clutched the pistol more firmly. The potent fumes had, in truth, wrought their fiendish work on the innocent beast. Diogenes had just put it out of its misery, and his two familiars were preparing to mount one of the horses, whilst he and the Stadtholder had the other two by the reins.
Why not?
The miscreant was sure enough of his aim, and the others would be unprepared. He was sure, too, of the swiftness of his horse, and the Spanish outposts were less than a quarter of a league away, whilst within half that distance Stoutenburg was on the watch with a vedette, waiting to capture the Stadtholder on his runaway horse as it had been prearranged.
Once there he -- Nicolaes -- would be amongst friends.
Then, why not?
Already the riders had put their horses to a trot. Diogenes and the Stadtholder on ahead, the two loons some few lengths in their rear. In less than three minutes they would be within range of Nicolaes' pistol and its blinding fumes. And Diogenes was riding on the side nearest to his enemy.
Nicolaes Beresteyn grasped his weapon more firmly. He realized with infinite satisfaction that his arm was perfectly steady. Indeed, he had never felt so absolutely calm. The measured tramp of the horses keyed him up to a point of unswerving determination. He raised his arm. The horses were galloping now. They would pass like a flash within twenty paces of him.
The next moment the sharp report of the pistol rang stridently through the mist. There was a burst, a flash, a column of smoke. Nicolaes jumped into the saddle and set spurs to his horse. The other riders went galloping on for a few seconds -- not more. Then one of them swayed in his saddle. Nicolaes then was a couple of hundred yards away.
"You are hit, man!" the Stadtholder exclaimed. "That abominable assassin ---"
But the words died in his throat. The reins had slipped out of Diogenes' grasp, and he rolled down into the mud.

A sudden jerk brought the Stadtholder's horse to a halt. He swung himself out of the saddle, ran quickly to his companion.
"You are hit, man!" he reiterated; this time with an unexplainable feeling of dread.
The other seemed so still, and yet his clothes and the soft earth around him showed no stains of blood.
Pythagoras now was also on the spot. He had slid off the horse as soon as the infamous assassin had started to ride away. Socrates was trying to give chase. Even now two pistol-shots rang out in quick succession right across the moorland. But the hell-hound was well mounted, and the avenging bullets failed to reach their mark. All this the Stadtholder took in with a rapid glance, even whilst Pythagoras, round-eyed and scared, was striving with gentle means to raise the strangely inert figure.
"He hath swooned," the Stadtholder suggested.
The stricken man had one arm across his face. His had had fallen from his head, leaving the fine, square brow free and the crisp hair weighted by the sweat of some secret agony. The mouth, too, was visible, and the chin, with its four days' growth of beard, the mouth that was always ready with a smile. It was set now in an awesome contraction of pain, and, withal, that terrible immobility.
Now Socrates was arriving. A moment or two later he, too, had dismounted, cursing lustily that he had failed to hit the hell-hound. A mute query, an equally mute reply, was all that passed between him and Pythagoras.
Then
