The “Luminous” BBC Period Drama That Pride & Prejudice Fans Need To Discover

Fans of classic period dramas are discovering a hidden BBC gem that has been praised as a “luminous” and “triumphant” adaptation of one of Anthony Trollope’s most fascinating novels.

He Knew He Was Right brings together romance, jealousy, social expectations and emotional turmoil in a gripping Victorian-era drama that explores how suspicion and insecurity can slowly destroy even the strongest relationships.

Originally broadcast by the BBC, the psychological drama has recently gained fresh attention from viewers who are praising its elegant storytelling, impressive performances and beautifully recreated historical world.

A Marriage Destroyed By Jealousy

The story follows Louis Trevelyan, played by Oliver Dimsdale, a wealthy Victorian gentleman who becomes consumed by the belief that his wife Emily, portrayed by Laura Fraser, is having an inappropriate relationship with Colonel Osborne, a charming older man played by Bill Nighy.

But what begins as a suspicion soon becomes something far more destructive.

Louis becomes trapped by his own jealousy, convinced that he is right despite the lack of evidence. His obsession slowly damages his marriage and pushes both characters into an emotional battle shaped by pride, insecurity and the strict social rules of the era.

Writer Andrew Davies adapted Trollope’s novel for the BBC, describing the story as a Victorian-era version of Shakespeare’s Othello — a tale where jealousy becomes a powerful force capable of tearing lives apart.

Viewers Praise The Stunning Adaptation

The series has received glowing reactions from viewers who praised everything from the performances to the production design.

One fan described the adaptation as “brilliant,” highlighting Caroline Martin’s performance as Dorothy and praising the entire cast for bringing Trollope’s lengthy novel to life.

They also praised the production’s attention to detail, including the decision to move the setting from Exeter to Wells, Somerset, where locations such as Vicars’ Close and the Cathedral Close helped create an authentic Victorian atmosphere.

Another viewer called the series a “triumph,” praising the BBC for transporting audiences back in time with convincing locations, costumes and performances.

They wrote that the production was filled with “human interest” and praised how the characters felt realistic rather than exaggerated.

A Drama Full Of Complex Characters

While Louis’ jealousy drives much of the story, viewers have noted that the drama avoids presenting its characters as completely simple or one-dimensional.

Emily’s independence and refusal to follow her husband’s expectations create further conflict, reflecting the restrictions placed on women during the Victorian period.

The series explores not only romantic jealousy but also questions of marriage, power, reputation and the expectations placed on men and women during the 19th century.

That emotional complexity is one reason the drama continues to attract viewers years after its original release.

Perfect For Fans Of Classic Period Drama

For audiences who enjoy the romance, social tension and detailed worlds of shows like Pride & Prejudice, He Knew He Was Right offers a darker and more psychologically intense experience.

Rather than focusing only on romance, the series examines what happens when trust disappears and emotions take control.

With its lavish settings, memorable performances and deeply human conflicts, the BBC adaptation remains a compelling watch for anyone looking for a sophisticated period drama.

A forgotten BBC treasure. A beautifully crafted Victorian story. And a “luminous” period drama waiting to be rediscovered.
