"'That,' whispered Towler, 'is the back of a cupboard in the next 'ouse. If you was to pull that 'andle to the right, it would slide along same as this one. Only I expect there's somebody in the room there.'
"I rewarded Mr. Towler with half a sovereign, which he evidently thought liberal, and he departed gleefully. Shortly afterwards I learned that he had 'got a stretch' in connection with a 'job' at Camberwell; and he vanished from my ken. But I did not forget the sliding doors. No special use for them suggested itself, but their potentialities were so obvious that I resolved to keep a sharp eye on the second floor front next door.
"I had not long to wait. Presently the whole floor was advertised by a card on the street door as being to let and I seized the opportunity of a quiet Sunday to reconnoiter and put the arrangements in going order. I slid back the panel on my own side and then, dragging at the handle, pushed back the second panel. Both moved noisily and would require careful treatment. I passed through the square opening into the vacant room and looked round, but there was little to see, though a good deal to smell, for the windows were hermetically sealed and a closed stove fitted into the fireplace precluded any possibility of ventilation. The aroma of the late tenants still lingered in the air.
"I returned through the opening and began my labors. First, with a hard brush I cleaned out both sets of grooves, top and bottom. Then, into each groove I painted a thick coating of tallow and black lead, mixed into a paste and heated. By moving the panels backwards and forwards a great number of times I distributed the lubricant and brought the black lead to such a polish that the doors slid with the greatest ease and without a sound. I was so pleased with the result that I was tempted to engage the room next door, but as this might have aroused suspicion—seeing that I had a whole house already—I refrained; and shortly afterwards the floor was taken by a family of Polish Jews, who apparently supplemented their income by letting part of it furnished.
"I now pass over an intervening period and come to the circumstances of one of my most interesting and stirring experiences. It was about this time that some misbegotten mechanician invented the automatic magazine pistol, and thereby rendered possible a new and execrable type of criminal. It was not long before the appropriate criminal arrived. The scene of the first appearance was the suburb of Tottenham, where two Russian Poles attempted, and failed in, an idiotic street robbery. The attempt was made in broad daylight in the open street, and the two wretches, having failed, ran away, shooting at every human being they met. In the end they were both killed—one by his own hand—but not until they had murdered a gallant constable and a poor little child and injured in all, twenty-two persons.
"I read the newspaper account with deep interest and the conviction that this was only a beginning. Those two frenzied degenerates belonged to a common enough type; the type of the Slav criminal who has not sense enough to take precautions nor courage enough to abide the fortune of war. The automatic pistol, I felt sure, would bring him into view; and I was not mistaken.
"One night, returning from a tour of inspection, I met a small excited crowd accompanying a procession of three police ambulances. I joined the throng and presently turned into a small blind thoroughfare in which had gathered a small and nervous-looking crowd and a few flurried policemen. Several of the windows were shattered and on the ground were three prostrate figures. One was dead, the others were badly wounded, and all three were members of the police force.
"I watched the ambulances depart with their melancholy burdens and then turned for information to a bystander. He had not much to give, but the substance of his account—confirmed later by the newspapers—was this: The police had located a gang of suspected burglars and three officers had come to the house to make arrests. They had knocked at the door, which, after some delay, was opened. Some person within had immediately shot one of the officers dead and the entire gang of four or five had rushed out, fired point blank at the other two officers, and then raced up the street shooting right and left like madmen. Several people had been wounded and, grievous to relate, the whole gang of miscreants had made their escape into the surrounding slums.
"I was profoundly interested and even excited for several reasons. In the first place, here at last was the real Lombroso criminal, the sub-human mattoid, devoid of intelligence, devoid of the faintest glimmering of moral sense, fit for nothing but the lethal chamber; compared with whom the British 'habitual' was a civilized gentleman. Without a specimen or two of this type, my collection was incomplete. Then there was the evident applicability of my methods to this class of offender; methods of quiet extermination without fuss, public disorder or risk to the precious lives of the police. But beyond these there was another reason for my interest. The murder of my wife had been a purposeless, unnecessary crime, committed by some wretch to whom human life was a thing of no consideration. There was an analogy in the circumstances that seemed to connect that murder with this type of miscreant. It was even possible that one of these very villains might be the one whom I had so patiently sought through the long and weary years.
"The thought fired me with a new enthusiasm. Forthwith I started to pursue the possible course of the fugitives, threading countless by-streets and alleys, peering into squalid courts and sending many a doubtful-looking loiterer shuffling hastily round the nearest corner. Of course it was fruitless. I had no clue and did not even know the men. I was merely walking off my own excitement.
