It is to be hoped that he succeeded in settling any medical points of a knotty character that might be hovering in his brain, and certain it is that he had become quite absorbed in an abstruse matter connected with physiology, when his ears were startled, and he was at once aroused to a full consciousness of where he was, and why he had come there, by the distant sound of a man’s footstep.

It was a footstep which seemed to be that of a person who scarcely thought it at all necessary to use any caution, and the doctor’s heart leaped within him as in the lowest possible whisper he said to himself,—­

“I am successful—­I am successful.  It is believed now that the Hall is deserted, and no doubt that is Sir Francis Varney come with confidence, to carry out his object in so sedulously attacking it, be that object what it may.”

Elated with this idea, the doctor listened intently to the advancing footstep, which each moment sounded more clearly upon his ears.

It was evidently approaching from the garden entrance towards the house, and he thought, by the occasional deadened sound of the person’s feet, be he whom he might, that he could not see his way very well, and, consequently, frequently strayed from the path, on to some of the numerous flower-beds which were in the way.

“Yes,” said the doctor, exultingly, “it must be Varney; and now I have but to watch him, and not to resist him; for what good on earth is it to stop him in what he wishes to do, and, by such means, never wrest his secret from him.  The only way is to let him go on, and that will I do, most certainly.”

Now he heard the indistinct muttering of the voice of some one, so low that he could not catch what words were uttered; but he fancied that, in the deep tones, he recognised, without any doubt, the voice of Sir Francis Varney.

“It must be he,” he said, “it surely must be he.  Who else would come here to disturb the solitude of an empty house?  He comes! he comes!”

Now the doctor could see a figure emerge from behind some thick beeches, which had before obstructed his vision, and he looked scrutinisingly about, while some doubts stole slowly over his mind now as to whether it was the vampyre or not.  The height was in favour of the supposition that it was none other than Varney; but the figure looked so much stouter, that Mr. Chillingworth felt a little staggered upon the subject, and unable wholly to make up his mind upon it.

The pausing of this visitor, too, opposite that window where Sir Francis Varney had made his attempts, was another strong reason why the doctor was inclined to believe it must be him, and yet he could not quite make up his mind upon the subject, so as to speak with certainty.

A very short time, however, indeed, must have sufficed to set such a question as that at rest; and patience seemed the only quality of mind necessary under those circumstances for Mr. Chillingworth to exert.
