The first act of the Inspector, on lodging his prisoner in jail, was to visit his rooms in Glasgow. There in a battered leather portmanteau he discovered a large cashbox of hardened steel which when broken open was found to contain the balance of Mr. Averill’s money. With the £2000 which had been paid to Messrs. Dashwood and Munce, no less a sum than £36,562 was recovered, no doubt all the old miser had possessed. Ruth Averill therefore received her fortune intact, and between the consequent easing of her circumstances and her engagement to Pierce Whymper, she found the happiness which had been denied her during her early years.

The history of the crime, as French at last presented it, made very terrible reading. Like most accounts of human weakness and guilt, it arose from small beginnings and increased stage by stage, until at last almost inevitably it reached its frightful consummation.

The trouble first arose in that house near the Ransome Institute in Kintilloch, when Dr. Philpot discovered that he and his wife had nothing in common and that their marriage had been a fatal blunder. There is no need to recount the steps by which they drifted apart: it is enough to say that within two years of the wedding their hatred was mutual and bitter. Then Philpot became intimate with the nurse whom Roper afterwards found him embracing in the Institute shrubbery, and from that time the idea of getting rid of his wife by murder was never far from the doctor’s mind. At first he did not see how this could be done, but as he brooded over the problem a method presented itself, and coldly and deliberately he made his preparations.

First, he selected a time when his wife should be alone with him in the house. Taking advantage of Flora’s absence one afternoon, he made a pretext to get Mrs. Philpot up to the bedroom landing. Silently he slipped upstairs after her and across the top of the lower flight he tied a dark-brown silk cord. Then, returning to the study, he called to her for Heaven’s sake to come quickly for the house was on fire. She rushed down, caught her foot in the cord, and fell headlong to the hall below. She was stunned though not killed, but Philpot was prepared for this eventuality. Seizing the only implement he could find, a cricket bat, he struck her savagely on the temple, killing her instantaneously. As he expected, the blow made a bruise such as she might have received from the fall, and no suspicion was aroused by it.

But an unexpected contingency had given Philpot away. He had supposed that the servant, Flora, had really gone to visit her sick mother. But in this he was mistaken. It was to see, not her mother but her lover, Roper, that the girl had left the house, and this afternoon, like many another before it, she met him in a near-by copse. There, just after they had greeted each other, a heavy shower came on, and Flora had proposed an adjournment to the kitchen for shelter. To this Roper had agreed, and they had just settled down therein for their fifteen minutes’ chat when they heard Philpot’s shout to his wife, followed in a moment by Mrs. Philpot’s scream of terror and the crash of her fall. Flora involuntarily sprang to her feet and ran up the stairs from the basement to the hall. But she was transfixed by the sight which met her eyes and she stood rigid, gazing at Philpot. Roper had by this time crept up the stairs behind her, and both actually saw the doctor commit the murder. Flora was about to reveal herself, but Roper’s grip tightened upon her wrist and held her motionless. Watching thus, they saw Philpot rapidly examine the body, and apparently satisfied that life was extinct, wipe the cricket bat and replace it in the stand. Then he ran upstairs and removed the silk cord, afterwards stooping over the floor on the half-way landing. They could not see what he was doing, but the evidence given later as to the hole in the carpet made his action clear.

Then followed a dramatic moment. When Philpot came downstairs he found Roper and Flora standing in the hall, and they soon let him know that they had witnessed the whole of his terrible proceedings. Philpot attempted to bluster, but he was quite unable to carry it off, and at last he asked Roper what he proposed to do.

Roper, in his way quite as unscrupulous as the doctor, had instantly thought how he might turn the affair to his own advantage, and he quickly stated his terms. If Philpot would increase his ten shillings a week to forty, thus enabling Roper and Flora to marry in comfort, the evidence against him would be withheld. Philpot protested, but Roper was adamant and the doctor had to give way. Had that been all that Roper required, the matter would have been settled in five minutes. But the attendant pointed out that unless he had some material proof of the crime, his hold over Philpot would be gone by the evening: if he did not give his testimony at once he would have to explain later why he had withheld it. He would therefore follow the precedent he had set in the case of the nurse, and would require from Philpot a signed confession of the murder. He swore solemnly to keep this secret as long as the money was paid, but with equal solemnity swore to send it anonymously to the police the first time the two pounds failed to materialise. Again Philpot blustered, but again he had to give way. But he pointed out that a confession would take some time to prepare, and that if he wrote it then and there the body would be cold before the police and another doctor were called in, which would give the whole affair away. Roper admitted this difficulty and proposed the following solution. He would give Philpot until nine o’clock that night to write it. If it was not forthcoming Flora and he would visit the police station with the yarn that Flora alone had seen what had taken place—but without revealing herself to Philpot; that she had been so frightened she did not know what to do; that she had consulted him, Roper, and that he had told her she must immediately reveal what she knew.

Philpot had perforce to agree to this, and by nine o’clock the confession was ready. But Philpot with perverse ingenuity found a way of tricking his adversary and rendering it useless. He was an extraordinarily clever draughtsman and had frequently amused himself by forging the handwriting of others. Now he forged his own. He wrote the confession out, and then copied it, letter by letter, upside down. The result was a passable imitation of his own handwriting, but one which any expert would recognise as a forgery. If the document were produced his denial of its authorship would be accepted without question.

But Philpot did not wish the document to be produced. It was too horribly credible, and inquiries by the police might easily lead to some discovery which would convict him. With all the appearance of reluctant good faith he therefore handed over the document and promised to pay the two pounds a week with the utmost regularity. Roper, believing in the value of his instrument and fearing Philpot might make an effort to regain it, rented a box in a safe deposit and stored it there.

Some four months later Philpot, as already stated, left the Ransome Institute and put up his plate at Thirsby. There he speedily made the acquaintance of Mr. Averill. The old man indeed called him in, thinking that the fees of a newcomer who had to make his way would be less than those of a well-established practitioner.
