The visitor continued gazing either at that window, or at the whole front of the house, for several minutes, and then he turned away from a contemplation of it, and walked slowly along, parallel with the windows of that dining-room, one of which had been broken so completely on the occasion of the admiral’s attempt to take the vampyre prisoner.

The moment the stranger altered his position, from looking at the window, and commenced walking away from it, Mr. Chillingworth’s mind was made up.  It was not Varney—­of that he felt now most positively assured, and could have no doubt whatever upon the subject.

The gait, the general air, the walk, all were different; and then arose the anxious question of who could it be that had intruded upon that lonely place, and what could be the object of any one else but Varney the vampyre to do so.

The stranger looked a powerful man, and walked with a firm tread, and, altogether he was an opponent that, had the doctor been ever so belligerently inclined, it would have been the height of indiscretion for him to attempt to cope with.

It was a very vexatious thing, too, for any one to come there at such a juncture, perhaps only from motives of curiosity, or possibly just to endeavour to commit some petty depredations upon the deserted building, if possible; and most heartily did the doctor wish that, in some way, he could scare away the intruder.

The man walked along very slowly, indeed, and seemed to be quite taking his time in making his observations of the building; and this was the more provoking, as it was getting late, and if having projected a visit at all, it would surely soon be made, and then, when he found any one there, of course, he would go.

Amazed beyond expression, the doctor felt about on the ground at his feet, until he found a tolerably large stone, which he threw at the stranger with so good an aim, that it hit him a smart blow on the back, which must have been anything but a pleasant surprise.

That it was a surprise, and that, too, a most complete one, was evident from the start which the man gave, and then he uttered a furious oath, and rubbed his back, as he glanced about him to endeavour to ascertain from whence the missile had come.

“I’ll try him again with that,” thought the doctor; “it may succeed in scaring him away;” and he stooped to watch for another stone.

It was well that he did so at that precise moment; for, before he rose again, he heard the sharp report of a pistol, and a crashing sound among some of the old wood work of which the summer-house was composed, told him that a shot had there taken effect.  Affairs were now getting much too serious; and, accordingly, Dr. Chillingworth thought that, rather than stay there to be made a target of, he would face the intruder.

“Hold—­hold!” he cried.  “Who are you, and what do you mean by that?”—­“Oh! somebody is there,” cried the man, as he advanced.  “My friend, whoever you are, you were very foolish to throw a stone at me.”
