guardian of the law had been a stranger and had insisted on examining the bag, nothing could have been more apparently innocent than its contents. But the guilty man finds it hard to avoid projecting into the minds of others the secret knowledge that his own mind harbours.
When Pottermack at last let himself in at his front door and secured it with bolt and chain, he breathed a sigh of relief. The horrible chapter was closed. Tomorrow he could clear away the last souvenirs of that hideous scene in the garden and then, in the peace and security of his new life, try to forget the price that he had paid for it. So he reflected as he carried the tub to the scullery and drew into it enough water to account for the vanished ice; as he washed at the sink, as he sat at the table consuming the arrears of his supper, and as, at length, he went up to bed, carrying the rucksack with him.
CHAPTER IV
The Placing of the Sun-Dial
When, after breakfast on the following morning, Mr. Pottermack betook himself, rucksack in hand, to the walled garden, he experienced, as he closed the door behind him and glanced round the enclosure, curiously mixed feelings. He was still shaken by the terrific events of the previous night, and, in his disturbed state, disposed to be pessimistic and vaguely apprehensive. Not that he regretted what he had done. Lewson had elected to make his life insupportable, and a man who does that, does it at his own risk. So Pottermack argued, and he reviewed the circumstances without the slightest twinge of remorse. Repugnant as the deed had been to him, and horrible as it had been in the doing—for he was by temperament a humane and kindly man—he had no sense of guilt. He had merely the feeling that he had been forced to do something extremely unpleasant.
When, however, he came to review the new circumstances, he was conscious of a vague uneasiness. Considered in advance, the making away with Lewson had been a dreadful necessity, accepted for the sake of the peace and security that it would purchase. But had that security been attained? The blackmailer, indeed, had gone for ever with his threats and his exactions. But that thing in the well—It was actually possible that Lewson dead might prove more formidable even than Lewson living. It was true that everything seemed to be quite safe and secret. He, Pottermack, had taken every possible precaution. But supposing that he had forgotten something; that he had overlooked some small but vital detail. It was quite conceivable. The thing had frequently happened. The annals of crime, and especially of murder, were full of fatal oversights.
So Mr. Pottermack cogitated as, having picked up the apron, he made his way to the workshop, where he set to work at once on the tasks that remained to be done. First he dealt with the shoes. As it would have been difficult and was quite unnecessary to remove the gutta-percha soles, he simply shaved off the heels, heated the surface and then stuck on the original soles of balata.
Next he broke up the plaster moulds and casts into small fragments, which he carried out in the bucket and shot down the well. Those, he reflected with a sense of relief as he replaced the hurdle, were the last visible traces of the tragedy; but even as he turned away from the well, he saw that they were not. For, glancing at the summer-house, he observed the decanter, the siphon, and the tumbler still on the table. Of course, to no eye but his was there anything suspicious or unusual in their presence there. But the sight of them affected him disagreeably. Not only were they a vivid and unpleasant reminder of events which he wished to forget. They revived the doubts that had tended to fade away under the exhilarating influence of work. For here was something that he had overlooked. A thing of no importance, indeed, but still a detail that he had forgotten. Trivial as the oversight was, he felt his confidence in his foresight shaken.
He walked to the summer-house, and, setting down the bucket outside, entered and proceeded to clear away these traces. Opening the cupboard, he caught up the siphon and the decanter and stepped behind the table to put them on the shelves. As he did so, he felt something soft under his foot, and when he had closed the cupboard door he looked down to see what it was. And then his heart seemed to stand still. For the thing under his foot was a coat—and it was not his coat.
There is a very curious phenomenon which we may describe as deferred visual sensation. We see something which is plainly before our eyes, but yet, owing to mental preoccupation, we are unaware of it. The image is duly registered on the retina; the retina passes on its record to the brain; but there the impression remains latent until some association brings it to the surface of consciousness.
Now, this was what had happened to Pottermack. In the moment in which his glance fell on the coat there started up before him the vision of a bulky figure flourishing its fists and staggering backwards towards the well—the figure of a man in shirt-sleeves. In spite of the darkness, he had seen that figure quite distinctly; he even recalled that the shirt-sleeves were of a dark grey. But so intense had been his preoccupation with the dreadful business of the moment that the detail, physically seen, had passed into his memory without conscious recognition.
He was literally appalled. Here, already, was a second oversight; and this time it was one of vital importance. Had any one who knew Lewson been present when the coat was discovered, recognition would have been almost certain; for the material was of a strikingly conspicuous and distinctive pattern. Then the murder would have been out, and all his ingenious precautions against discovery would have risen up to testify to his guilt.
All his confidence, all of the sense of security that he had felt on his return home on the previous night, had evaporated in an instant. Two obvious things he had forgotten, and one of them might have been fatal. Indeed, there were three; for he had been within an ace of overlooking those incriminating footprints that might have led the searchers to his very gate. Was it possible that there was yet some other important fact that he had failed to take into account? He realized that it was very possible indeed; that it might easily be that he should add yet another instance to the abundant records of murderers who, covering up their tracks with elaborate ingenuity, have yet left damning evidence plain for any investigator to see.
He picked up the coat, and, rolling it up loosely, considered what he should do with it. His first impulse was to drop it in the well. But he rejected the idea for several reasons. It would certainly float, and might possibly be seen by the mason when the sun-dial was fixed, especially if he should throw a light down. And then, if the well should, after all, be searched, the presence of a separate coat would be against the suggestion of accident. And it would be quite easy to burn it in the rubbish destructor. Moreover, in rolling the coat he had become aware of a bulky object in one of the pockets which recalled certain statements that Lewson had made. In the end, he tucked the coat under his arm and, catching up the bucket, took his way back to the workshop.
It was significant of Pottermack’s state of mind that as soon as he was inside he locked the door; notwithstanding that he was alone in the walled garden and that both the gates were securely fastened. Moreover, before he began his inspection he unlocked a large drawer and left it open with the key in the lock, ready to thrust the coat out of sight in a moment. Then he unrolled the coat on the bench, and, putting his hand into the inside breast pocket, drew out a leather wallet. It bulged with papers of various kinds, mostly bills and letters, but to these Pottermack gave no attention. The one item in the contents that interested him was a compact bundle of banknotes. There were twenty of them, all five-pound notes, as he ascertained by going through the bundle; a hundred pounds in all—the exact sum that had been demanded of him. In fact, these notes were understudies of his expected contribution. They had been “borrowed” by Lewson out of the current cash to meet some sudden call, and his, Pottermack’s, notes were to have been either paid in place of them or to have enabled Lewson to make good his loan in the morning.
It seemed a queer proceeding, and to Mr. Pottermack it was not very intelligible. But the motive was no concern of his; what was his concern was the train of consequences that would be set going. The obvious fact was that the little branch bank of which Lewson had had sole charge was now minus a hundred pounds in five-pound notes. That fact must inevitably come to light within a day or two; most probably this very day.
