The Wanderer stood still before the door.  In the freezing air, his quick-drawn breath made fantastic wreaths of mist, white and full of odd shapes as he watched the tiny clouds curling quickly into each other before the blackened oak.  Then he laid his hand boldly upon the chain of the bell.  He expected to hear the harsh jingling of cracked metal, but he was surprised by the silvery clearness and musical quality of the ringing tones which reached his ear.  He was pleased, and unconsciously took the pleasant infusion for a favourable omen.  The heavy door swung back almost immediately, and he was confronted by a tall porter in dark green cloth and gold lacings, whose imposing appearance was made still more striking by the magnificent fair beard which flowed down almost to his waist.  The man lifted his heavy cocked hat and held it low at his side as he drew back to let the visitor enter.  The latter had not expected to be admitted thus without question, and paused under the bright light which illuminated the arched entrance, intending to make some inquiry of the porter.  But the latter seemed to expect nothing of the sort.  He carefully closed the door, and then, bearing his hat in one hand and his gold-headed staff in the other, he proceeded gravely to the other end of the vaulted porch, opened a great glazed door and held it back for the visitor to pass.

The Wanderer recognized that the farther he was allowed to penetrate unhindered into the interior of the house, the nearer he should be to the object of his search.  He did not know where he was, nor what he might find.  For all that he knew, he might be in a club, in a great banking-house, or in some semi-public institution of the nature of a library, an academy or a conservatory of music.  There are many such establishments in Prague, though he was not acquainted with any in which the internal arrangements so closely resembled those of a luxurious private residence.  But there was no time for hesitation, and he ascended the broad staircase with a firm step, glancing at the rich tapestries which covered the walls, at the polished surface of the marble steps on either side of the heavy carpet, and at the elaborate and beautiful iron-work of the hand-rail.  As he mounted higher, he heard the quick rapping of an electric signal above him, and he understood that the porter had announced his coming.  Reaching the landing, he was met by a servant in black, as correct at all points as the porter himself, and who bowed low as he held back the thick curtain which hung before the entrance.  Without a word the man followed the visitor into a high room of irregular shape, which served as a vestibule, and stood waiting to receive the guest’s furs, should it please him to lay them aside.  To pause now, and to enter into an explanation with a servant, would have been to reject an opportunity which might never return.  In such an establishment, he was sure of finding himself before long in the presence of some more or less intelligent person of his own class, of whom he could make such inquiries as might enlighten him, and to whom he could present such excuses for his intrusion as might seem most fitting in so difficult a case.  He let his sables fall into the hands of the servant and followed the latter along a short passage.
