The Rise and Fall of Infamous Serial Killer Mary Ann Cotton 

Mary Ann attempted to nudge Robinson gently toward life insurance discussions, but this tactic inadvertently brewed suspicion within him. Sparked by this, Robinson took matters into his own hands and investigated, uncovering astonishing facts about Mary Ann’s behind-the-scenes activities.

It was revealed that Mary Ann was buried under £60 of debt and had embezzled around £50 from her husband. Armed with this information, and after a tumultuous legal battle, Robinson was able to sever ties with Mary Ann, securing sole guardianship of their son, George, and putting a dramatic end to their shared chapter.
