The footman made no reply, but ascended the steps of the old house, gave three taps with the iron hammer, and returned to open the coach door.  An old man possessed of the heraldic lore so common in that day examined the shield of arms on the panel.

“Azure, a lion’s head erased, between three flowers de luce,” said he, then whispered the name of the family to whom these bearings belonged.  The last inheritor of its honors was recently dead, after a long residence amid the splendor of the British court, where his birth and wealth had given him no mean station.  “He left no child,” continued the herald, “and these arms, being in a lozenge, betoken that the coach appertains to his widow.”

Further disclosures, perhaps, might have been made had not the speaker been suddenly struck dumb by the stern eye of an ancient lady who thrust forth her head from the coach, preparing to descend.  As she emerged the people saw that her dress was magnificent, and her figure dignified in spite of age and infirmity—­a stately ruin, but with a look at once of pride and wretchedness.  Her strong and rigid features had an awe about them unlike that of the white Old Maid, but as of something evil.  She passed up the steps, leaning on a gold-headed cane.  The door swung open as she ascended, and the light of a torch glittered on the embroidery of her dress and gleamed on the pillars of the porch.  After a momentary pause, a glance backward and then a desperate effort, she went in.

The decipherer of the coat-of-arms had ventured up the lower step, and, shrinking back immediately, pale and tremulous, affirmed that the torch was held by the very image of old Caesar.

“But such a hideous grin,” added he, “was never seen on the face of mortal man, black or white.  It will haunt me till my dying-day.”

Meantime, the coach had wheeled round with a prodigious clatter on the pavement and rumbled up the street, disappearing in the twilight, while the ear still tracked its course.  Scarcely was it gone when the people began to question whether the coach and attendants, the ancient lady, the spectre of old Caesar and the Old Maid herself were not all a strangely-combined delusion with some dark purport in its mystery.  The whole town was astir, so that, instead of dispersing, the crowd continually increased, and stood gazing up at the windows of the mansion, now silvered by the brightening moon.  The elders, glad to indulge the narrative propensity of age, told of the long-faded splendor of the family, the entertainments they had given and the guests, the greatest of the land, and even titled and noble ones from abroad, who had passed beneath that portal.  These graphic reminiscences seemed to call up the ghosts of those to whom they referred.  So strong was the impression on some of the more imaginative hearers that two or three were seized with trembling fits at one and the same moment, protesting that they had distinctly heard three other raps of the iron knocker.
