A physician of eminence in the town, on being called in to visit the last surviving sister, was so strongly impressed with the opinion that her sickness and sudden death had been caused by poison, that he examined with much care many of the vessels in the house, inquired if any water for poisoning flies had been used, and expressed a wish to open the body; but the family being all dead, and no persons at hand who thought themselves authorised to give that permission, the corpse was interred unopened, and with it the opportunity for detection. During the time of the fatal illness in the Misses Kitchin's house, Mary Bateman was unremitting in her attention; she administered their food, and from her hands the medicine was conveyed to their lips. Some time after the death of these ladies their creditors looked over their effects, when it was found that their house and shop had been plundered of almost everything they contained: and to add to the embarrassment of their affairs, the shop books were missing. The creditors only divided eightpence in the pound.

Two young women, then servants in Leeds, had long been in Mary's toils, and she had fleeced them pretty handsomely; and not only them, but their friends, for she had prevailed upon one of them to rob her mother of several articles, and amongst the rest of a large family Bible. When she had got all from them that could be extorted without awakening the suspicions of their friends, she sent both these deluded girls, at different times, to seek service in Manchester, cautioning them, if they met, not to speak to each other, on pain of breaking the charm. When they arrived in Manchester, Mary contrived to keep up a correspondence with them, and got from them even the clothes they wore, so that they were almost reduced to a state of nakedness. One day these poor destitute girls met in the streets of Manchester; the meeting being quite unexpected, they both burst into tears, and their emotions became so violent that further concealment was out of the question. They thereupon related to each other their sad history, and by comparing notes, found that they were both the dupes of Mary Bateman. They then wrote to Leeds, and laid their case before their friends, who interfered in their behalf, and got from the witch part of the property she had so wickedly extorted.

The witch also contrived to ingratiate herself into the good opinion of another young woman, and got from her several sums of money for the purpose of curing her of an "evil wish" laid upon her by an old beggar-woman whom she had refused to relieve. The cure was to be effected by Miss Blythe, to whom a pocket-handkerchief was to be sent. In due course the directions arrived, and Miss Blythe, who, like Mrs. Moore, could never put her charms in motion without money, required that different sums, amounting in all to five guineas, should be produced, and as much wearing apparel as was worth about the same sum; but this money and these clothes were only to be kept till the evil wish was removed, and then to be restored to the owner. The period fixed for the opening of the mysterious bags, in which these articles were deposited, had arrived, when one day a person brought a fruit-pie to the young woman, telling her that her sweetheart had sent it. This pie she tasted, and let a fellow-servant partake with her, but though very nice in appearance, the taste was hot and offensive; they in consequence desisted from eating it, and the young woman took it down to Mary Bateman to ask her opinion. Mary affected that she knew nothing herself of such things, but she would send it to the sagacious Miss Blythe. This, as the simple girl supposed, was done, and Miss Blythe informed her that it was very well she had not eaten much of the pie, for if she had, it would have been her last, as it was "full of poison!" Soon after the girl opened the bags, and found that her guineas had turned to copper and her clothes to old rags!

In the year 1807, Bateman, who, owing to the conduct of Mary, never remained long in one place, removed into Meadow Lane. While living in this situation a very extraordinary circumstance occurred, and it is not improbable that Mary was in some way privy to the transaction. A man of the name of Joseph Gosling, a cloth-dresser, had been long out of employ, and his family, which consisted of a wife and four children, was reduced to great extremity. One day the whole of the family had been out for some time, when one of the children, a boy about seven years of age, returned, and found on the table a small cake; the mother and other children soon after returned, and partook of this cake. They immediately became so sick as to render medical aid necessary. Mr. Atkinson, the surgeon, was then sent for, and by administering emetics saved the lives of the family. On analysing the cake it was found to contain a large quantity of arsenic. It is impossible to say why or by whom this poisonous bread was placed in the situation in which the boy found it, and the only reason why it is supposed to have been placed there by Mary Bateman is the knowledge that poisonous drugs were much in use by her, that human life was in her estimation of little value; and that the cries or tricks of the children may have inconvenienced her.

In the month of April, 1807, Judith Cryer, a poor old washerwoman, and a widow, was occasioned uneasiness by the misconduct of her grandson, a boy about eleven years of age. Winifred Bond, a person who had some dealings with Mary Bateman, either as her dupe or her agent, recommended the old woman to apply to Mary, as a person who could remove the cause of her distress. Judith consented to consult her; Mary soon found out the foible of the poor woman. An inordinate fear about the future fate of this darling grandson was the spring in Judith's mind on which the witch found she could play with success. She recommended that an application should be made to Miss Blythe, a lady of her acquaintance, who she said lived at Scarboro', but who, in fact, had no more real existence than the invisible Mrs. Moore. She then undertook to write to her dear friend. In a few days an answer was received from this lady, which shocked Judith beyond description. The letter contained the representation of a gallows, with a rope dangling from it. The letter also stated that the grandson would be executed before he attained the age of fourteen years, unless the catastrophe was prevented by the old woman raising four guineas, and applying them as Miss Blythe should direct. To raise such a sum seemed as impossible to poor Judith as to pay the National Debt. At last, however, she contrived to scrape it together with the utmost difficulty. When raised, it was, as Mary pretended, to remain unapplied till she received further instructions from Miss Blythe. The instructions at length arrived, and ordered that three guineas should be put into a leathern bag, and sewed up in Judith's bed, where they were to remain untouched till the boy had attained the age of fourteen. The former part of these directions were, as far as concerned Judith, faithfully complied with—Mary, as she thought, deposited the money as directed; but when the witch was afterwards apprehended, Judith opened her bed, took out the bag, and found it empty.

Mary having embraced the faith of the followers of Joanna Southcote, got introduced to the houses of many of them, and invariably robbed them: sometimes by practising on their fears, and at others by absolute theft.

In the year 1808, Bateman's family removed to Camp Field, in Water Lane, and there Mary met with a new and profitable subject for the exercise of her villainous arts. The wife of James Snowden, a neighbour, had a sort of presentiment that one of her children would be drowned; but whether this notion proceeded from morbid fancies originating in her own mind, or was suggested to her by Mary Bateman, is not known. Mary Bateman offered her services, or rather the services of Miss Blythe, to save the child from a watery grave. Miss Blythe was then represented as living at Thirsk, and a letter was received from her, directing that James Snowden's silver watch should be sewed up in the bed by Mary Bateman. This was accordingly done.

Next, money to the amount of twelve guineas was required. Letters were received from Miss Blythe, directing that this money should also be sewn up in the bed, to be restored when the charm had taken effect. By-and-bye it was found necessary to increase the terrors, and in addition to the death of the son, Miss Blythe suggested that ill would befall the daughter, unless the family left Leeds, and removed to Bowling, near Bradford. The bed containing the charms they were allowed to take with them, but it was thought expedient to leave a considerable portion of their property in the house, and deposit the key with Bateman.

At length they expressed a wish to be allowed to rip open the bed and take out the watch and money, but the proper time, they were told, had not yet arrived; and before the property was taken out, the family of Snowden was to take a DOSE, which was at that time in preparation for them, and was to have been administered about the end of October, 1808. Happily for them this dose was never taken.
