Katerfelto did his duty, and Nelly scarcely left the patient's bedside for a minute at a time. If skill and attention could have saved him, old Carew might have been kept alive for many a week to come; but the last few grains in the hour-glass seem to dribble away the fastest, and it was no more obvious to the doctor who watched, than to the girl who prayed, that with sinking strength and failing vitality, the question was no longer of days, but of hours. In this her sore distress, how could John Garnet find it in his heart to leave the neighbourhood of the woman he loved? How could he bear to think of her loneliness, protected only by the hateful attentions of Parson Gale? He lingered on imprudently enough, visiting the house at frequent intervals for news of the dying man, and pressing many a crown-piece on the sorrowful servant, who was the only person visible to answer his inquiries. Yet his pale and anxious looks had been marked by loving eyes, swimming in tears because of his constancy, his danger, and the promise that forbade further warning or expostulation. Herself unseen, Nelly caught a glimpse of her lover more than once--and so did Katerfelto. His presence filled the Charlatan with indignation and alarm. They had been concerned together in a conspiracy against the Government, and either of them, so argued Katerfelto, could hang the other. If John Garnet recognised him, it was more than probable that he would endeavour to secure his own safety, or at least a commutation of capital punishment, by informing against his confederate. The grey horse, the arms, the money, all would be traced back to the master-spirit that originated the plot, and there would be no escape for him then! John Garnet must be destroyed at once, without scruple and without delay. The means were close at hand. The Parson made no secret of his attachment to Nelly Carew, and Katerfelto seemed to know by instinct that in such a character as Gale's, jealousy once aroused could be lulled by nothing short of a deadly and final revenge. After all, he did but act in self-defence! He owed John Garnet a grudge, perhaps, for the abduction of Waif; but it was no question of petty injuries or reprisals now. Simply a choice of evils. John Garnet or himself had to pay the penalty of high-treason at Tyburn. Of course, it must be John Garnet! So, when Parson Gale rode down to Porlock on his daily visit of inquiry, the Charlatan motioned him into the little parlour, and closed the door on their conference, with a mysterious face. "My business here," he began, in his dry, sarcastic tone, "lies with symptoms rather than affections, and concerns the liver more than the heart. Nevertheless, I can understand men's devices, though I cannot sympathise with their follies, and I see well enough, Master Gale, there is no price you would grudge to pay for a pair of blue eyes that are sore with weeping and watching in the chamber overhead."
