quite what Lewson had expected. Trusting to the moral effect of his greatly superior size and weight, he had bluffed confidently. Now it seemed that he had got to make good his threat, and the truth is that he was not eager for the fray. However, it had to be done, and done as impressively as possible. After pausing for another couple of seconds, he proceeded, with a formidable air (but unobserved by Pottermack, whose back was still turned to him), to take off his coat and fling it on the table, whence it slipped down on to the floor. Then, stepping outside the summer-house, he bent forward, and, with an intimidating roar, charged like an angry rhinoceros.
At the sound of his stamping feet Pottermack spun round and faced him, but then stood motionless until his assailant was within a yard of him, when he sprang lightly aside, and as the big, unwieldy bully lumbered past him, he followed him closely. As soon as Lewson could overcome the momentum of his charge, he halted and turned; and instantly a smart left-hander alighted on his cheek and a heavy right-hander impinged on his ribs just below the armpit. Furious with the pain, and utterly taken aback, he cursed and grunted, hitting out wildly with all the viciousness of mingled rage and fear for now he realized with amazement that he was hopelessly outclassed by his intended victim. Not one of his sledge-hammer blows took effect on that agile adversary, whereas his own person seemed to be but an unprotected target on which the stinging blows fell in endless and intolerable succession. Slowly at first, and then more quickly, he backed away from that terrific bombardment, followed inexorably by the calm and scientific Pottermack, who seemed to guide and direct his backward course as a skilful drover directs the movements of a refractory bullock.
Gradually the pair moved away from the vicinity of the summer-house across the dark lawn, the demoralized bully, breathing hard and sweating profusely, reduced to mere defence and evasion while his light-footed antagonist plied him unceasingly with feint or blow. Presently Lewson stumbled backward as his foot sank into the loose, heaped earth at the margin of the cleared space; but Pottermack did not press his advantage, renewing his attack only when Lewson had recovered his balance. Then the movement began again, growing faster as the big man became more and more terrified and his evasion passed into undissembled retreat; deviously and with many a zig-zag but always tending towards the centre of the cleared area. Suddenly Pottermack’s tactics changed. The rapid succession of light blows ceased for an instant and he seemed to gather himself up as if for a decisive effort. There was a quick feint with the left; then his right fist shot out like lightning and drove straight on to the point of the other man’s jaw, and as his teeth clicked together with an audible snap, Lewson dropped like a pole-axed ox, falling with his body from the waist upwards across the mouth of the well and his head on the brick edge, on which it struck with a sickening thud.
So he lay for a second or two until the limp trunk began to sag and the chin came forward on to the breast. Suddenly the head slipped off the brick edge and dropped into the cavity, shedding its cap and carrying the trunk with it. The heavy jerk started the rest of the body sliding forward, slowly at first, then with increasing swiftness until the feet rose for an instant, kicked at the farther edge and were gone. From the black pit issued vague, echoing murmurs, followed presently by a hollow, reverberating splash; and after that, silence.
It had been but a matter of seconds. Even as those cavernous echoes were muttering in the unseen depths, Pottermack’s knuckles were still tingling from the final blow. From the moment when that blow had been struck he had made no move. He had seen his enemy fall, had heard the impact of the head on the brick edge, and had stood looking down with grim composure on the body as it sagged, slid forward, and at last made its dreadful dive down into the depths of its sepulchre. But he had moved not a muscle. It was a horrible affair. But it had to be. Not he, but Lewson had made the decision.
As the last reverberations died away he approached the forbidding circle of blackness, and kneeling down at its edge, peered into the void. Of course, he could see nothing; and when he listened intently, not a sound came to his ear. From his pocket he brought out his little electric lamp and threw a beam of light down into the dark cavity. The effect was very strange and uncanny. He found himself looking down a tube of seemingly interminable length while from somewhere far away, down in the very bowels of the earth, a tiny spark of light glowed steadily. So even the last ripples had died away and all was still down in that underworld.
He replaced the lamp in his pocket, but nevertheless he remained kneeling by the well-mouth, resting on one hand, gazing down into the black void and unconsciously listening for some sound from below. Despite his outward composure, he was severely shaken. His heart still raced, his forehead was damp with sweat, his body and limbs were pervaded by a fine, nervous tremor.
Yet he was sensible of a feeling of relief. The dreadful thing that he had nerved himself to do, that he had looked forward to with shuddering horror, was done. And the doing of it might have been so much worse. He was relieved to feel the screw-bolt in his pocket—unused; to think that the body had slipped down into its grave without the need of any hideous dragging or thrusting. Almost, he began to persuade himself that it had been more or less of an accident. At any rate, it was over and done with. His merciless enemy was gone. The menace to his liberty, the constant fear that had haunted him were no more. At last—at long last—he was free.
Fear of discovery he had none; for Lewson, in his own interests, had insisted on strict secrecy as to their acquaintance with each other. In his own words, “he preferred to sit on his own nest-egg.” Hence to all the world they were strangers, not necessarily even aware of each other’s existence. And the blackmailer’s stealthy arrival and his care in silently shutting the gate gave a guarantee that no one had seen him enter.
While these thoughts passed somewhat confusedly through his mind, he remained in the same posture; still unconsciously listening and still gazing, as if with a certain expectancy, into the black hole before him, or letting his eyes travel, now and again, round the dark garden. Presently an opening in the dense pall of cloud that obscured the sky uncovered the moon and flooded the garden with light. The transition from darkness to brilliant light—for it was full moon—was so sudden that Pottermack looked up with a nervous start, as though to see who had thrown the light on him; and in his overwrought state he even found something disquieting in the pale, bright disc with its queer, dim, impassive face that seemed to be looking down on him through the rent in the cloud like some secret watcher peeping from behind a curtain. He rose to his feet, and, drawing a deep breath, looked around him; and then his glance fell on something more real and more justly disquieting. From the edge of the grass to the brink of the well was a double track of footprints, meandering to and fro, zig-zagging hither and thither, but undeniably ending at the well.
Their appearance was sinister in the extreme. In the bright moonlight they stared up from the pale buff soil, and they shouted of tragedy. To the police eye they would have been the typical “signs of a struggle,” the tracks of two men facing one another and moving towards the well with, presently, a single track coming away from it. No one could mistake the meaning of those tracks; nothing could explain them away—especially in view of what was at the bottom of the well.
The first glance at those tracks gave Pottermack a severe shock. But he recovered from it in a moment. For they were mere transitory marks that could be obliterated in a minute or two by a few strokes of a rake and a few sweeps of a besom; and meanwhile he stooped over them, examining them with a curious interest not unmixed with a certain vague uneasiness. They were very remarkable impressions. He had already noted the peculiar quality of this loamy soil; its extraordinary suitability for making casting-moulds. And here was a most striking illustration of this property. The prints of his own feet were so perfect that the very brads in his soles were quite clear and distinct, while as to Lewson’s, they were positively ridiculous. Every detail of the rubber soles and the circular rubber heels came out as sharply as if the impressions had been taken in moulding-wax. There was the prancing horse of Kent—the soles were of the Invicta brand and practically new—with the appropriate legend and the manufacturers’ name, and in the central star-shaped space of the heels was the perfect impression of the screw. No doubt the singular sharpness of the prints was due to the fact that
