So profound was the impression produced by the murder that, from the day it was discovered, no person could be induced to lodge or sleep in the house in which it was committed. The tenants all left without giving notice, and the landlady, prostrated by the blow, has not dared, since that awful night, to venture inside the door. The house is avoided, shunned, and dreaded by all. Any human being bold enough to take it could have it for a term of years on a very moderate rental—for the first year, probably, for a peppercorn; but practical people as we are, with our eyes on the main chance, we are imbued with sentiments which can never be eradicated. The poorest family in London could not, at the present time, be induced to occupy the house. The stain of blood is on those floors and stairs, and it can never be washed out! The Spirit of Murder lurks within the fatal building, and when night falls, the phantom holds terrible and undisputed sway over mind and heart. A shapeless shadow glides from room to room—no features are visible but eyes which never close, and which shine only in the dark. And in the daylight, which in this house is robbed of its lustre, its presence is manifest in the echo of every step that falls upon the boards. Appalling spectre! whose twin brother walks ever by the side of the undiscovered murderer! Never, till justice is satisfied, shall it leave him. As he stole from the spot in which he took the life of a fellow-creature, it touched his heart with its spiritual hand, and whispered, “I am the shadow of thy crime! Thou and I shall never part!” He looks into the glass, and it peers over his shoulder; maddened, he flies away, and when he stops to rest, he feels the breath of the Invisible on his cheek. He slinks into his bed, and hiding his head in the bedclothes, lies there in mortal terror, knowing that the shadow is close beside him. It brings awful visions upon him. He looks over the bridge into the river upon which the sun is shining. How bright is the water! How clear! How pure! Surely over that white surface the shadow can have no power! But suddenly comes a change, and the river is transformed into a river of blood. An irresistible fascination draws him to the river again in the night, when the moon is shining on the waters, and, as he gazes downwards, he sees the ghastly body of his victim, its face upturned, floating on a lurid tide. He cannot avoid it; whichever way he turns it is before him. He walks through country lanes, and trembles at the fluttering of every leaf. Rain falls; it is red; and as he treads along, it oozes up and up till it reaches his eyes, and, resting there, tinges everything that meets his sight with the colour of blood. Water he cannot drink, its taste is so horrible. He must have gin, brandy—any poison that will help him to forget. Vain hope! He shall never forget! And the shadow of his crime shall never leave until he falls at the feet of outraged justice, and pays the penalty. Then, and then only, there may be hope for him—for God is merciful!

Among the measures adopted by the police for the discovery of the Great Porter Square murderer was that of having the house, No. 119, watched day and night by policemen in private clothes. There are not many persons in the kingdom who, in a murder case which has thrilled the public heart and filled it with horror, would accuse the police of want of zeal; but there are many who, with justice, would accuse them of want of tact.

A week after the murder was committed, Policeman X (as it is not of an individual, but of a system, we complain, we will not make this particular constable’s name more prominent than it has already become)—a week then after the murder was committed, Policeman X, in private clothes, saw lurking in the vicinity of Great Porter Square, a man: as he might see to-night other men lurking in the vicinity of any and every square in London. It is a peculiarity of policemen in private clothes that they are always ready to suspect, and that in their eyes every poor-looking person with whose face they are not familiar is a disreputable character. Policeman X watched this man for a few moments, and took the opportunity of brushing past him when they were near a lamp-post. The man’s face was unknown to him; it was haggard and pale, and his clothes betokened poverty. These were terrible signs, and Policeman X at once set himself the task of stealthily following the man, who walked leisurely towards the house, No. 119, in which the murder was committed. The house was deserted and untenanted, as it is at the present time. Now, would the suspected man pass the house, or would he linger near it? Much depended upon this.

The man reached the house, peered around (according to Policeman X’s statement) to make sure that he was not observed, and then cast his eyes to the dark windows. He lingered, as though in indecision, for a few moments, and standing before the door, appeared to be studying the number. Then he strolled away. It cannot be said that there was anything criminating in these movements, but Policeman X, determined not to lose sight of his man, followed him at a cautious but convenient distance. The man sauntered round the Square, and presently commenced to munch some stale bread and cheese, portions of which were afterwards found upon him. He completed the circuit of the Square, and for the second time paused before No. 119. Again he studied the number on the door, and again he looked up at the dark windows. Not satisfied with his inspection in that direction, he stooped down to the grating above the area, and appeared to listen. Still not satisfied, he ascended the two steps which led to the street door, and tried the handle.

Nothing more was needed. “I have the murderer!” thought Policeman X, with a thrill of satisfaction; and without further hesitation, he walked quickly up, clapped his hand on the man’s shoulder, and said—

“What are you doing here?”

The sudden appearance of a human being out of the shadows probably so startled the suspected man that he did not know what to reply. He thrust his head forward in the endeavour to distinguish the features of the questioner. The next words uttered by Policeman X had more meaning in them. With his hand still on the man’s shoulder, he said, sternly—

“Come with me!”

The reply given to the invitation was the reply which the writer, or any of the readers of this article, would have given on the impulse of the moment. It is to be borne in mind that the policeman was in private clothes, and might, as far as appearances went, himself have been a murderer in the eyes of another man dressed in private clothes, who, in his turn (for what is sauce for the goose is sauce for the gander) might himself have been a policeman.
