"Well, you remember no doubt what happened after that. A police inspector called straightway on Messrs. Whiskin and Sons, and elicited from them the information that effectively No. 13 Wicklow Lane was for sale, had been for some time, and that on the previous morning—it was, of course, Thursday—a well-dressed gentleman had called to make enquiries about the house. Young Mr. Whiskin gave him the key and asked him to be sure and return it before 1 p.m. as the office closed early on Thursdays. Well, the gentleman hadn't come back yet with the key, but Mr. Whiskin was not troubling much about that, there being nothing in the house—nor for a matter of that in the street—likely to tempt a thief. Young Mr. Whiskin thought that he would be able to identify the gentleman if he saw him again. He had rather a red face and a thick nose, which suggested that he was accustomed to good living, rough ginger-coloured hair, and a straggly ginger beard and walrus moustache, all of which gave him rather a peculiar appearance. He wore a neat brown lounge-suit, a light overcoat, and grey Homburg hat, and he was carrying a large parcel under his arm. Mr. Whiskin added that he had never seen the man before or since.
"As soon as these facts became known there was more voluntary information forthcoming. It appears that one or two of the residents in Wicklow Lane remembered seeing a man in light overcoat and soft grey hat, and carrying a parcel under his arm, enter No. 13 with a latchkey. No one had taken 'pertikler notice,' however, chiefly because the occurrence was not an unusual one. Often people would go in to look at the empty house and come out again after inspection. Unfortunately, too, because of this there was distinct confusion of evidence, some witnesses declaring that the man carried a large parcel, and that he went away again, but not until the evening; others would have it that he had a very small parcel, and that he wore a bowler hat; others that the man with the bowler hat was another person altogether, and did not call till the evening, whilst this, again, was contradicted by another witness who said that the man who called in the evening had very conspicuous ginger-coloured hair and beard, but that he certainly wore a bowler hat. And through this mass of conflicting evidence there was always the fact that the fog was very thick that night and that no one therefore was able to swear very positively to anything.
"This, then, being all the information that could be gathered for the moment from the outside, the police next decided to force an entry into the empty house. Its unlucky number justified, as you know, its sinister reputation, because the first sight that greeted the inspector when he entered the front room on the ground floor was the body of a man lying in a pool of blood. At first glance he looked like a foreigner—youngish, and with jet-black hair and moustache. By the side of him there was a damp towel, also stained with blood. Closer examination revealed the fact that he was not dead, but he seemed in a dead faint, and the inspector sent one of the men off at once to telephone for the divisional surgeon.
"The wounded man was dressed in a dark suit. He had on a gold watch of foreign make, twenty pounds in notes, and some loose silver in his pockets, and a letter addressed to 'Allen Lloyd, Esq.' at an hotel at Boulogne. The letter was a private one, relating unimportant family events; it was signed by a Christian name only, and bore a London postmark, but no address. The police inspector took charge of the letters and the money, and as the divisional surgeon had now arrived and was busy with the wounded man, he proceeded to examine the premises.
"The houses in Wicklow Lane all have small yards at the back. These yards end in a brick wall, the other side of which there is a railway cutting. It was obvious that No. 13 had been untenanted for some time. The dust of ages lay over window and door-frames, over broken mantelpieces and dilapidated stoves. There was not a stick of anything anywhere; even the rubbish in the basement—such as is found in every empty house, residue left over by the last tenant—had been picked over until there was nothing left but dust and a few empty bottles.
"The front room in which the wounded man lay revealed very little. Two bullets were found lodged in one of the walls; one, quite close to the ceiling, suggesting that it had been fired in the air, and the other at a height of seven feet from the ground. The dust on the floor had certainly been disturbed, but by how many pairs of feet it was impossible to say. On the other hand, the back room on the same floor had quite a grim tale to tell. It gave on the small backyard with the wall as a background, beyond which was the railway cutting. The window in this room was open. In one corner there was an ordinary sink which showed that water had been running from the tap quite recently; there was a small piece of soap in the sink which had also recently been used. On the mantelpiece a small oak-framed mirror was propped up against the wall and beside it on the shelf there was the remnant of a burnt-out candle and a box of matches, half empty. And thrown down on the floor, in a corner of the room, were a black Inverness cape and soft black hat with a very wide brim, such as are usually affected by French students.
"It was, of course, difficult to reconstruct the assault just at present, the wounded man being still in a state of stupor and unable to give any account of himself, but the revolver was found lying at the bottom of the yard close to the end wall.
"In the meanwhile the divisional surgeon had concluded his examination. He pronounced the wound to have been caused by one of the bullets that had lodged in the wall of the front room. It had been fired at very close range, as the flesh was singed all round the wound. The bullet had gone right through the left deltoid, front to back, and slightly upwards, just grazed the top of the shoulder, and then lodged in the wall. The surgeon was inclined to think that the wound was self-inflicted, but this theory was thought to be untenable, because if a man was such an obviously poor shot he would surely have chosen some other way of putting an end to himself, unless, indeed, he was a lunatic, which might account for any incongruity in the known facts, even to the noise—the shouting and the banging—that all the neighbours agreed had preceded the revolver shots.
"But there certainly was one fact which discounted the attempted suicide theory, and that was the undoubted presence of another man upon the scene—the man with the ginger hair and the thick nose who had called for the key at Messrs. Whiskin and Sons, and whom several witnesses had actually seen entering the empty house, the man with the parcel. Now no one saw him come out again by the front door. He must have been in the house when the foreigner with the jet-black hair came and joined him, and he must have slipped out later on in the dark, under cover of the fog and rain, either by the front door when nobody happened to be passing by, or over the wall and then by the railway cutting. Now what had brought these two men together in an empty house, in one of the worst slums in London? One man was wounded; where was the other? Had the revolver been dropped by one of them in his flight or flung out of the window by a lunatic? Was it attempted suicide by a madman, or murder consequent on a quarrel, or blackmail? None of these questions was ever answered, nor was the man with the ginger-coloured hair ever found. There was absolutely no clue by which he might be traced; the earth just swallowed him up as if he had been a spook.
"Nor was the identity of the wounded man ever satisfactorily established. Who he was, where he came from, who were his associates and what were his antecedents, he never revealed. He was detained in hospital for a time, as he certainly was suffering from loss of memory. But presently they had to let him go. He had money and he was otherwise perfectly sane, but to every question put to him he only answered, 'I don't know! I can't remember!' He spoke English without the slightest trace of foreign accent; all that was foreign about him was his jet-black hair and beard. Nor was the history of the revolver ever traced to its source. Where was it bought? To whom was it sold, and by whom? Nobody ever knew."
