“In, quick!” said the visitor hoarsely; and pressing the doctor back once more, he stood listening for a few moments as if for pursuers, and then, wild-eyed and strange, he followed Dr Chartley into the surgery, closing the door and leaning back against it breathing heavily, his eyes staring wildly round, his sun-browned face twisting, while a nervous disposition to start and run seemed to pervade him in every gesture.

The fog and smoke which came in with him added to the strangeness of his aspect as he stood there; his hair rather long, unkempt, and wet with fog; his hands gloveless, and high boots spattered with mud and soaked with half-molten snow. There was more of the brigand in his aspect than of the honest man, and yet his drawn, agitated face was well featured and not unpleasing, besides which his wandering eyes suggested fear suffered, and not a likelihood of inspiring fear; unless it should be, as the doctor surmised, that he was mad, and the pursuit he evidently feared were that of his keepers.

It formed a strange picture—the bland, smooth shining-pated doctor facing this wild excited man standing with his back to the door, his hands outspread as if to keep it fast, and his head half-turned as he listened for the sound of steps in the stillness of the winter night.

“Will you be seated?” said the doctor blandly. “Can I be of any service?”

“Hush! Can you hear anything? There! that!” cried the newcomer, in an excited whisper. “They’re coming!”

“Yes; mad,” said the doctor to himself. Then aloud, “The sound you hear is the dripping of the melting snow on the pavement.”

“Hah! Are you sure?”

“Oh, yes. Quite sure. Sit down, my dear sir. No, not here; come to my consulting-room. There is a fire.”

The coolness of a doctor in dealing with ordinary delirium or insanity is in its way as heroic as the manner in which a soldier will face fire. To most men the advent of the strange visitor would have suggested calling in help or taking instant steps for self-preservations; but armed with weapons such as would prostrate his visitor should he prove inimical, the doctor calmly led the way into his consulting-room, poked the fire, turned up the lamp a little, and pointed to a chair, watching his visitor keenly the while to satisfy himself whether his behaviour was the result of fever, drink, or an unbalanced brain.

The man glared at the doctor for a moment, stepped quickly to the room door, opened it, listened, drew back again, closed it, and slipped the bolt on the inside.
