Britain's Most Evil Killers

After ending his marriage to Maria, his bigamous wife, Malcolm Pearson, now engaged to his innocent fiancée Janet, realises the true threat posed by his former partner. Their discovery shows just how dangerous Maria truly is.

Maria Pearson is a programme presented as a single episode. It is listed simply as an episode‑type entry, with the title itself serving as the only identifying detail. The format is straightforward, offering a self‑contained story rather than a series or multi‑part narrative. The central storyline follows the aftermath of a breakup with Maria. Once the relationship ends, the man’s other partner – a bigamous wife named Malcolm Pearson – and his new, unsuspecting fiancée, Janet, are forced to confront the reality of his past. Both women soon realise that the woman he left behind is far more perilous than they had imagined. Malcolm Pearson, described as his bigamous wife, and Janet, characterised as an innocent fiancée, each come to understand the threat posed by the former lover. Their discovery is driven by the unsettling behaviour of the ex‑partner, whose true nature proves to be considerably dangerous. The episode tracks how these two women, from very different backgrounds, share the common realisation of the ex’s capacity for harm. In the final moments, the danger that the ex‑partner represents becomes unmistakably clear to both Malcolm and Janet. Their newfound awareness underscores the episode’s focus on how past relationships can harbour unexpected risks, leaving the characters to grapple with the unsettling truth about the woman they once loved.
