There was an epidemic of murder in the United Kingdom about 1848-9. In November of the first-named year occurred the wholesale slaughter of the Jermys in their house, Stanfield Hall, by the miscreant Rush. Soon afterwards, in Gloucestershire, a maidservant, Sarah Thomas, murdered her mistress, an aged woman, by beating out her brains with a stone. Next year John Gleeson Wilson, at Liverpool, murdered a woman, Ann Henrichson, also a maidservant and two children; while in Ireland a wife dashed out her husband's brains with a hammer. London did not escape the contagion, and prominent among the detestable crimes of the period stands that of the Mannings at Bermondsey. These great criminals suffered at Horsemonger Lane Gaol, but they were tried at the Central Criminal Court, and were for some time inmates of Newgate. Their victim was a man named Patrick O'Connor, a Custom-House gauger, who had been a suitor of Marie de Roux before she became Mrs. Manning. Marie de Roux up to the time of her marriage had been in service as lady's-maid to Lady Blantyre, daughter of the Duchess of Sutherland, and Manning hoped to get some small Government appointment through his wife's interest. He had failed in this as well as in the business of a publican, which he had at one time adopted. After the marriage a close intimacy was still maintained between O'Connor and the Mannings. He lived at Mile End, whence he walked often to call at No. 3, Minver Place, Bermondsey, the residence of his old love. O'Connor was a man of substance. He had long followed the profitable trade of a money-lender, and by dint of usurious interest on small sums advanced to needy neighbours, had amassed as much as ten thousand pounds. His wealth was well known to "Maria," as he called Mrs. Manning, who made several ineffectual attempts to get money out of him. At last this fiendish woman made up her mind to murder O'Connor and appropriate all his possessions. Her husband, to whom she coolly confided her intention, a heavy brutish fellow, was yet aghast at his wife's resolve, and tried hard to dissuade her from her bad purpose. In his confession after sentence he declared that she plied him well with brandy at this period, and that during the whole time he was never in his right senses. Meanwhile this woman, unflinching in her cold, bloody determination, carefully laid all her plans for the consummation of the deed.
