Who was the killer in Seven Dials?
In fact, there was more than one killer in Agatha Christie’s Seven Dials. Moreover, a grander conspiracy was afoot, involving Jimmy Thesiger (Edward Bluemel), Lady Caterham (Helena Bonham Carter) and Lorraine Wade (Ella-Rae Smith), who were plotting to steal and sell Dr Cyril Matip’s (Nyasha Hatendi) formula for an indestructible metal.
Who was responsible for Gerry’s death in Agatha Christie’s Seven Dials?
The narrative begins with the murder of WWI veteran and Foreign Office employee Gerry Wade (Corey Mylchreest) at the residence of Bundle and her mother, Lady Caterham, known as Chimneys. The culprit behind Gerry’s demise was his half-sister Lorraine, who poisoned him by repeatedly spiking his champagne with a potent sleeping draught during the party at Chimneys.
She orchestrated his death under the belief that he was privy to the plot to pilfer Matip’s formula. Lady Caterham acknowledged that action was necessary but deemed Lorraine’s method “drastic” and labelled her “impulsive” for taking Gerry’s life.
Bundle stumbled upon Gerry’s last letter, hinting that his conversation with Lorraine about Seven Dials might have sealed his fate.
Who was behind Ronny’s death in Agatha Christie’s Seven Dials?
Ronny Devereux (Nabhaan Rizwan) met his end when Jimmy shot him to keep him from uncovering the truth. Jimmy became embroiled in the conspiracy due to his mounting debts and desperate need for a financial lifeline.
His monetary troubles were hinted at early in the series when he received a call from a representative at Lloyds.
Who was behind Jimmy’s shooting in Agatha Christie’s Seven Dials?
In a cunning ploy to mislead Superintendent Battle, portrayed by Martin Freeman, Jimmy staged his own shooting at Wyvern Abbey. He wore an oversized glove to prevent leaving fingerprints and discarded the firearm out of the window.
Using his teeth, he removed the glove and attempted to incinerate it in the fireplace, albeit with limited success. This diversionary tactic was designed to allow Lorraine to drug Matip and pilfer the formula.

Why did Lady Caterham take part in the conspiracy?
Bundle’s mother, Lady Caterham, was revealed as the brains behind the conspiracy, although she refrained from any direct involvement in murder. She was driven by a desperate need for funds to maintain their expensive estate following the death of her husband, Lord Caterham, played by Iain Glen.
The demise of her son in the war further compounded her financial woes, leaving her feeling obligated to shoulder the financial responsibilities in the absence of a male figure in the household.
In addition to her financial struggles, Lady Caterham was also grappling with the grief of losing her husband and son, both of whom had died serving their country. The senseless loss of their lives left her embittered.
Consequently, she had no qualms about selling state secrets to the enemy, given how her family had been treated by Britain.
What happened to Bundle at the end of Agatha Christie’s Seven Dials?
Bundle found herself coerced at gunpoint to visit the Seven Dials Club, where she encountered the cloaked and masked individuals she’d previously seen plotting around Wyvern Abbey. She was invited to join the Seven Dial Society, an organisation that, contrary to her initial suspicions, was dedicated to safeguarding the world rather than perpetrating murders.
Battle, upon removing his mask, was unveiled as the leader of this clandestine group. He expressed to Bundle his belief in her potential to exceed her father, a former member of the Seven Dials Society.
Taken aback by this revelation, Bundle agreed to join their ranks and combat malevolent forces.

What happened to Bundle’s father in Agatha Christie’s Seven Dials?
At the outset of the series, Bundle’s father met a tragic end, gored by a bull in an abandoned bullring in Ronda, Spain in 1920 while on a case. He discovered a note adorned with a clock face just before his demise.
Battle disclosed that he had been Lord Caterham’s partner but arrived too late to prevent his friend’s murder.
Superintendent Battle proposed that those responsible for Matip’s sister’s death and the threats against the doctor for the formula were also behind the assassination. This unresolved mystery leaves room for Bundle to return for further investigation alongside the Seven Dials Society.
Netflix has yet to announce whether the show will be renewed for another series.
