Dr. Addington arrived at midnight. From the condition of the patient, coupled with what he learned from him and Mr. Norton, the doctor had no doubt Mr. Blandy was suffering from the effects of poison. He at once informed the daughter, and inquired if her father had any enemies. "It is impossible!" she replied. "He is at peace with all the world and all the world is at peace with him." She added that her father had long suffered from colic and heartburn, to which his present indisposition was doubtless due. Dr. Addington remained in the sick-room until Sunday morning (the 11th), when he left, promising to return next day. He took with him the sediment from the pan and the packet rescued from the fire, both of which were delivered to him by Mr. Norton. At this time neither physician nor apothecary knew the precise nature of the powder. Before he quitted the house, Dr. Addington warned Mary that if her father died she would inevitably be ruined.
Her position was now, one would think, sufficiently precarious; but the infatuated woman took a further fatal step. Her "love" for her murderous little gallant moved her to warn him of their common danger. She wrote to him at Lennel House, Coldstream, and asked Littleton, who had been in the habit of directing her letters to Cranstoun, to seal, address, and post the missive as usual. But Littleton, aware of the dark cloud of suspicion that had settled upon his master's daughter, opened it and read as follows:—"Dear Willy,—My father is so bad that I have only time to tell you that if you do not hear from me soon again, don't be frightened. I am better myself. Lest any accident should happen to your letters, take care what you write. My sincere compliments. I am ever yours." Littleton at once showed the letter to Mr. Norton, and afterwards read it to Mr. Blandy: "He said very little. He smiled and said, 'Poor love-sick girl! What won't a girl do for a man she loves?'"
There was then in the house Mary's uncle, Mr. Blandy, of Kingston, who had come to see his brother, and it was prudently decided, in view of all the circumstances, to refuse her access to the sick-room. But on the following morning (Monday, the 12th) Mr. Blandy sent by Susan Gunnell a message to his daughter "that he was ready to forgive her if she would but endeavour to bring that villain to justice." In accordance with the dying man's request, Mary was admitted to his room in presence of Susan and Mr. Norton. Unaware of the recovery of the powder and the interception of her letter, "she thanked God that she was much better, and said her mind was more at ease than it had been"; but, being informed of these damning discoveries, she fell on her knees by her father's bed and implored his forgiveness, vowing that she would never see or write to Cranstoun again. "I forgive thee, my dear," said the old man, "and I hope God will forgive thee; but thou shouldst have considered better than to have attempted anything against thy father." To which she answered, "Sir, as for your illness, I am entirely innocent." She admitted having put the powder into the gruel, "but," said she, "it was given me with another intent." Her father, "turning himself in his bed," exclaimed, "Oh, such a villain! To come to my house, eat and drink of the best my house could afford, and then to take away my life and ruin my daughter! Oh, my dear, thou must hate that man, must hate the ground he treads on, thou canst not help it!" "Sir," said Mary, "your tenderness towards me is like a sword piercing my heart—much worse than if you were ever so angry. I must down on my knees and beg you will not curse me." "I curse thee, my daughter," he rejoined, "how canst thou think I could curse thee? Nay, I bless thee, and hope God will bless thee also and amend thy life. Do, my dear, go out of my room and say no more, lest thou shouldst say anything to thine own prejudice"; whereupon, says Susan, who reports what passed, "she went directly out." Thus Mary and her father parted for the last time. It appears from this pathetic interview that the old man purposely treated her as Cranstoun's innocent dupe, to shield her, if possible, from the consequences of her guilt, of which, in the circumstances, he could have entertained no doubt.
Meanwhile Dr. Addington had applied to the mysterious powder the tests prescribed by the scientific knowledge of the time, which, if less delicate and reliable than the processes of Reinsch and Marsh—a red-hot poker was the principal agent—yielded results then deemed sufficiently conclusive. Judged by these experiments, Mrs. Morgan's mystic philtre was composed of nothing more recondite than white arsenic. When Dr. Addington called on Monday he found the patient much worse, and sent for Dr. Lewis, of Oxford, as he "apprehended Mr. Blandy to be in the utmost danger, and that this affair might come before a Court of judicature." He asked the dying man whether he himself knew if he had "taken poison often." Mr. Blandy said he believed he had, and in reply to the further question, whom he suspected to be the giver of the poison? "the tears stood in his eyes, yet he forced a smile, and said, 'A poor love-sick girl—I forgive her. I always thought there was mischief in those cursed Scotch pebbles.'" Dr. Lewis came, and confirmed Dr. Addington's diagnosis; by their orders Mary was that evening confined to her chamber, a guard was placed over her, and her keys, papers, "and all instruments wherewith she could hurt either herself or any other person" were taken from her. Dr. Addington graphically describes the scene when the guilty woman realised that all was lost. She protested that from the first she had been basely deceived by Cranstoun, that she had never put powder in anything her father swallowed, excepting the gruel drunk by him on the Monday and Tuesday nights, that she believed it "would make him kind to him [Cranstoun] and her," and that she did not know it to be poison "till she had seen its effects." She declined to assist in bringing her lover to justice—she considered him as her husband, "though the ceremony had not passed between them." In reply to further pertinent questions, e.g., whether she really pretended to believe in the childish business of the "love philtre"? why Cranstoun described it, if innoxious, as "powder to clean the pebbles with"? why, in view of her father's grave condition, she failed sooner to call in medical aid? and why she had concealed from him (Addington) what she knew to be the true cause of the illness? her answers were not such, says Dr. Addington, as gave him any satisfaction. She made, however, the highly damaging admission that, about six weeks before, she had put some of the powder into her father's tea, which Susan Gunnell drank and was ill for a week after. This was said in presence of Betty Binfield. Thus, it will be observed, Mary Blandy, on her own showing knew, long before she operated upon, the gruel at all, the baneful effects of the powder. Her statement that the motive for administering it was to make her father "kind" both to herself and Cranstoun should also be, in view of her subsequent defence, remembered.
On Tuesday, the 13th, the doctors found their patient delirious and "excessively weak." He grew worse throughout the day; but next morning he regained consciousness for an hour, and spoke of making his will in a day or two—a characteristic touch. He soon relapsed, however, and rapidly sinking, died at two o'clock in the afternoon of Wednesday, 14th August, 1751. So the end for which, trampling upon the common instincts of her kind and hardening her heart against the cry of Nature, she had so persistently and horribly striven, was at last attained—with what contentment to "The Fair Parricide," in her guarded chamber, may be left to the speculation of the curious. The servants had access to their mistress's room. That afternoon Miss Blandy asked Robert Harman, the footman, to go away with her immediately—to France, says one account—and offered him £500 if he would do so. He refused. At night, by her request, the cook, Betty Binfield, sat up with her. "Betty, will you go away with me?" she cried, so soon as they were alone. "If you will go to the Lion or the Bell and hire a post-chaise, I will give you fifteen guineas when you get into it, and ten guineas more when we come to London!" "Where will you go—into the North?" inquired the cautious cook; "Shall you go by sea?" and learning that the proposed excursion would include a voyage, Betty, being, as appears, a bad sailor, declined the offer. Her mistress then "burst into laughter," and said she was only joking! In the Narrative, written after her condemnation, Mary boldly denies that these significant incidents occurred; in her more elaborate Account she makes no reference to the subject. Those who saw her at this time testify to her extreme anxiety regarding her own situation, but say she showed no sign of sorrow, compassion, or remorse for her father's death.
The person charged with the duty of warding Mary in her chamber was Edward Herne, parish clerk of Henley, who some twelve years before had been employed in Mr. Blandy's office, and had since remained on intimate terms with the family. It would appear, from an allusion in a contemporary tract, that Herne was that "Mr. H——" whose pretensions to the hand of the attorney's daughter had once been politely rejected. If so, probably he still preserved sufficient of his former feeling to sympathise with her position and wink at her escape. Be the fact as it may, at ten o'clock next morning, Thursday, 15th August, Ned Herne, as Mary names him, leaving his fair charge unguarded, went off to dig a grave for his old master. So soon as the coast was clear, Mary, with "nothing on but a half-sack and petticoat without a hoop," ran out of the house into the street and over Henley bridge, in a last wild attempt to cheat her fate. Her distraught air and strange array attracted instant notice. She was quickly recognised and surrounded by an angry crowd—for the circumstances of Mr. Blandy's death were now common knowledge, and the Coroner's jury was to sit that day. Alarmed by her hostile reception, she sought refuge at the sign of the Angel, on the other side of the bridge, and Mrs. Davis, the landlady, shut the door upon the mob. There chanced then to be in the alehouse one Mr. Lane, who, with his wife, were interested spectators of these unwonted proceedings. Miss Blandy, having "called for a pint of wine and a toast," thus addressed the stranger—"Sir, you look like a gentleman; what do you think they will do to me?" Mr. Lane told her that she would be committed to the county gaol for trial at the Assizes, when, if her innocence appeared, she would be acquitted; if not, she would suffer accordingly. On receiving this cold comfort Mary "stamped her foot upon the ground," and cried, "Oh, that damned villain! But why should I blame him? I am more to blame than he, for I gave it him [her father] and knew the consequence." On cross-examination at a later stage, the witnesses were unable to swear whether the word she used was "knew" or "know." The distinction is obvious; but looking to the other evidence on the point, it is not of much importance. Mr. Alderman Fisher, a friend of Mr. Blandy and one of the jury summoned upon the inquest, came to the Angel and persuaded the fugitive to return. Though the distance was inconsiderable, Mr. Fisher had to convey her in a "close" post-chaise "to preserve her from the resentment of the populace." Welcomed home by the sergeant and mace-bearer sent by the Corporation of Henley to take her in charge, Mary asked Mr. Fisher how it would go with her. He told her, "very hard," unless she could support her story by the production of Cranstoun's letters. "Dear Mr. Fisher," said she, "I am afraid I have burnt some that would have brought him to justice. My honour to him will prove my ruin." If the letters afforded sufficient proof of Cranstoun's criminous intent, it hardly appears how the fact rhymes to Mary's innocence.
That day a post-mortem examination of Mr. Blandy's remains was made by Dr. Addington and others, and in the afternoon "at the house of John Gale, Richard Miles, Gent., Mayor and Coroner of the said town," opened his inquiry into the cause of death. An account of the proceedings at the inquest is printed in the Appendix. The medical witnesses examined were Drs. Addington and Lewis; Mr. Nicholson, surgeon in Henley; and the apothecary, Mr. Norton, who severally spoke to the symptoms exhibited by the deceased during life, the appearances presented by his body, and the result of the analysis of the powder. They were of opinion that Mr. Blandy died of poison, and that the powder was a poison capable of causing his death. The maids, Gunnell and Binfield, Harman the footman, and Mary's old flame, Ned Herne, were the other witnesses whose depositions were taken. Having heard the evidence, the jury found that Francis Blandy was poisoned, and that Mary Blandy "did poison and murder" him; and on Friday, 16th August, the mayor and coroner issued to the constables his warrant to convey the prisoner to the county gaol of Oxford, there to be detained until discharged by due course of law. That night Mr. Blandy's body was buried in the parish church at Henley. None of his relatives were present, Norton, his apothecary; Littleton, his clerk; and Harman, his footman, being the only mourners.
Miss Blandy was not removed to Oxford Castle till the following day, to enable her to make the arrangements necessary for a lengthy visit. By her request, one Mrs. Dean, a former servant of the family, accompanied her as her maid. Her tea caddy—"the cannisters were all most full of fine Hyson"—was not forgotten. At four o'clock on Saturday morning the ladies, attended by two constables, set out "very privately" in a landau and four, and, eluding the attention of the mob, reached Oxford about eleven. Mary's first question on arriving at the gaol was, "Am I to be fettered?" and, learning that she would not be put in irons so long as she behaved well, she remarked, "I have wore them all this morning in my mind in the coach." At first, we are told, "her imprisonment was indeed rather like a retirement from the world than the confinement of a criminal." She had her maid to attend her, the best, apartments in the keeper's house were placed at her disposal, she drank tea—her favourite Hyson—twice a day, walked at her pleasure in the keeper's garden, and of an evening enjoyed her game of cards. Her privacy was strictly respected; no one was allowed to "see her without her consent," though very extraordinary sums were daily offered for that purpose. What treatment more considerate could a sensitive gentlewoman desire? But the rude breath of the outer world was not so easily excluded. One day the interesting prisoner learned from a visitor the startling news that her father's fortune, of which, as he had left no will, she was sole heiress, had been found to amount to less than four thousand pounds! With what feelings would she recall the old attorney's boastful references to her £10,000 dower, the fame of which had first attracted her "lover," Cranstoun, and so led to results already sufficiently regrettable, the end of which she shuddered to foresee. How passionately the fierce woman must have cursed the irony of her fate! But to this mental torment were soon to be added physical discomfort and indignity. A rumour reached the authorities in London that a scheme was afoot to effect her rescue. On Friday, 25th October, the Secretary of State having instructed the Sheriff of the county "to take more particular care of her," the felon's fetters she had before feared were riveted upon her slender ankles; and there was an end to the daily walks amid the pleasant alleys of the keeper's garden. This broad hint as to her real position induced a different state of mind. The chapel services, hitherto somewhat neglected, were substituted for the mundane pastimes of tea-drinkings and cards, and the prison chaplain, the Rev. John Swinton, became her only visitor. To the pious attentions of that gentleman she may now be left while we see what happened beyond the narrow circuit of her cell.
