Netflix’s Seven Dials premieres on January 15, bringing a modern screen adaptation of The Seven Dials Mystery to life.
Set between post-war England and the lingering shadows of the early 1920s, the limited series reintroduces Lady Eileen “Bundle” Brent as she stumbles into a conspiracy that reaches far beyond a single suspicious death.
While the original novel unfolds as a contained country-house mystery, the Netflix adaptation expands its range, weaving espionage, political intrigue, and personal betrayal into a three-episode arc. What begins as the apparent misadventure of a family friend quickly escalates into a covert struggle involving secret societies, stolen inventions, and long-buried wartime loyalties.
This episode-by-episode guide breaks down Seven Dials in full, tracing how the mystery develops across all three episodes and how the series reinterprets Christie’s story for a contemporary audience, while preserving its core themes of deception, power, and moral reckoning.
Spoiler warning: The following episode guide discusses major plot points and the ending of Seven Dials.

Episode 1 – Bundle of Love
The series opens in Ronda, 1920. A man walks through the city toward the bullring, where he finds a letter waiting for him at the center of the arena. As he bends to retrieve it, the gates close behind him. A bull is released. The man is killed. Left behind on the ground is a card bearing the image of a clock stopped at seven o’clock.
Five years later, in 1925, the story shifts to Chimneys, the country home of Lady Eileen “Bundle” Brent. Her mother, Lady Caterham, is hosting a lavish house party that brings together aristocrats, industrialists, and members of the Foreign Office. The gathering has a clear purpose. Chimneys has been rented to the Cootes, a powerful industrial family seeking to negotiate a discreet agreement with the government.
Among the guests are Ronny Devereux and Bill Eversleigh, Foreign Office men plotting a prank on their colleague Gerry Wade, who has developed a habit of sleeping through mornings. Their plan is simple: hide a collection of alarm clocks in his bedroom so they all go off at once. Bundle is immediately drawn to Gerry, and the two share an easy, understated chemistry. It is also made clear that Bundle’s brother has recently died, and that Gerry was close to him during the war.
During the party, tensions surface beneath the politeness. Lady Coote is caught cheating at bridge and is lightly challenged by Gerry, who jokes about it. Her response is sharp and unsettling. She warns him that the last person who accused her of cheating regretted it for the rest of her life. The message is clear: the Cootes must be indulged at all costs.
The following morning, the hidden alarm clocks begin ringing throughout the house. Gerry, however, does not wake. Bundle goes upstairs and finds him dead in his bed.
A doctor quickly rules the death a misadventure, suggesting a fatal mix of alcohol and sleeping draughts or possibly suicide. Bundle immediately rejects both explanations. Gerry was known for sleeping through artillery fire at the Somme, and the entire point of the prank was that alarms never woke him. More importantly, she had reason to believe he was planning to propose to her. Suicide makes no sense.
As suspicion spreads, the Cootes leave Chimneys abruptly. Their assistant Bateman, who attended school with both Gerry and Bundle’s brother, departs with them. A tense exchange reveals the resentment simmering beneath class politeness: the Cootes may lack titles, but they have money and access, and they know it.
Determined to find answers, Bundle searches the bedroom where Gerry died, which had once been her own. When she forces open a locked desk, her grief spills over into rage. Inside, she finds a letter addressed to Gerry’s sister, Lorraine, warning her to forget what he mentioned about the Seven Dials.
Bundle confides in her mother. She is certain Gerry was murdered and vows not to stop investigating, even if forbidden. She also reveals something troubling: she saw the maid Emily speaking privately with Mrs. Coote before the family left, and Emily was visibly distressed.
Outside, Bundle hears a clock ringing in the garden. She finds it smashed, its hands fixed at seven. She phones Ronny, who admits the prank involved eight clocks, not seven, and that they were hidden throughout the room. Yet only seven were found on the mantel the next morning. One is missing.
Ronny agrees to attend the inquest with Bundle and keep their suspicions quiet. He is clearly shaken, as if he knows more than he is saying.
Bundle continues her investigation. The staff confirm there were no medicines on Gerry’s bedside table and that nothing was removed after his death. Emily then reveals that Mrs. Coote gave her a bottle of sleeping draught, making her feel disoriented and unwell. The bottle disappeared the night of the party. Bundle later finds an identical bottle in her own room. Emily insists she never gave it to Gerry.
The inquest proceeds as expected. Gerry’s death is officially ruled accidental.
Afterward, Bundle confronts Mrs. Coote, asking why she failed to tell the police that the sleeping draught was hers. Mrs. Coote dismisses the question, implying that pressing the matter would only cause harm.
Bundle shares the Seven Dials letter with Ronny and connects it to the clocks. Ronny urges her to stop. Bundle refuses. She reminds him that Gerry carried her brother off the battlefield and was a source of comfort to her family. She owes him the truth.
Soon after, Bundle notices she is being followed. She trails the man to a telephone box. After he leaves, she enters and asks the operator to reconnect the previous call. It was placed to Scotland Yard.
Bundle tells her mother she is going to London. Alone, Lady Caterham speaks to a photo of her late husband. It is the same man who died in the bullring in Ronda in 1920.
As Bundle drives toward London, seven telephones ring across the city, each answered in turn. Nearby lies the same clock-marked card from the opening scene.
Back at Chimneys, Lady Caterham receives a note addressed to her daughter. The warning is blunt: stay away from the Seven Dials, or it will be the end of her.
The episode ends on the road to London. Bundle spots an injured man lying ahead. It is Ronny. He has been shot. With his last breath, he tells her to inform Jimmy Thesiger of one thing only: Seven Dials. Ronny dies in her arms.
Episode 2 – Battle commences
The episode opens by returning to Ronda, 1920, expanding on the prologue glimpsed earlier in the series. A young man and his sister arrive in the city intending to meet Bundle’s father, unaware they are being watched. Before they can reach him, they are ambushed. The sister is shot and killed by a woman acting with precision and purpose, while her brother survives only by striking first. He kills the attacker and escapes, clutching an envelope that clearly carries dangerous weight. The man is later revealed to be Dr. Matip, and this moment establishes how long Seven Dials has been operating in the shadows.
Back in London, Bundle struggles to process Ronny’s death while trying to make sense of his final words. She shares her theory with Jimmy Thesiger, suggesting that Seven Dials may be connected to the Foreign Office, given that both Gerry and Ronny worked there. While she has ruled out Lady Coote, she is convinced the deaths are linked. Jimmy claims ignorance, but his discomfort is clear.
Their conversation is interrupted by the realization that they are being followed. The man trailing them turns out to be Superintendent Battle, who has already taken an interest in Gerry Wade’s death. Bundle confronts him directly, refusing to be intimidated. Battle admits he is investigating but remains guarded, subtly implying that Bundle herself could be closer to the truth than is safe. When she presents him with the unfinished letter Gerry was writing before his death, his tone shifts. Still, he urges her to step aside and leave the investigation to the authorities, a request she has no intention of honoring.
That evening, Bundle meets Bill Eversleigh for dinner and presses him about the Seven Dials Club. He initially deflects, but under pressure, admits it exists, though he downplays its significance. Unsatisfied, Bundle insists on seeing it for herself.
At the club, the atmosphere is loud and deliberately theatrical. Among the crowd, Bundle spots familiar faces, including Bateman, the Cootes’ assistant, and Alfred, a former footman from Chimneys. While dancing with Bill, she notices several women slipping away through a side entrance. Curious, she follows.
Up a winding staircase, Bundle breaks into a locked room and discovers something far removed from the club’s frivolous exterior. Inside is a table arranged like a clock face, with seven alarm clocks positioned exactly as they were after Gerry’s death. She barely has time to hide before a group of masked figures enters. Their faces are concealed behind clock motifs. As they speak, Ronny’s name is mentioned, followed by a chilling declaration: no one must be allowed to interfere. In that moment, Bundle understands that Seven Dials is not a joke, but an organized and dangerous network.
The next day, Bundle tells Jimmy what she witnessed, insisting they keep it secret. She also admits she deliberately withheld the truth from Bill, no longer trusting his ties to government circles.
Their investigation leads them to Lorraine Wade, who confirms that Gerry warned her away from Seven Dials. During the conversation, Jimmy accidentally reveals more than he should, exposing his own knowledge of the group. Lorraine also mentions an upcoming political gathering hosted by George Lomax at Wyvern Abbey, information that immediately catches Bundle’s attention.
Bundle wastes no time. She contacts Lomax directly and maneuvers her way into an invitation. Lomax soon visits Chimneys, where he meets Lady Caterham. During the conversation, he explains the real purpose of the gathering: to convince Dr. Matip to grant Britain exclusive rights to his invention, a technological breakthrough with enormous strategic implications. Lomax has already received a warning from Seven Dials regarding the device, and it is clear that foreign powers are watching closely.
At Wyvern Abbey, the guests arrive under the guise of leisure. Hunting parties fill the afternoon, while political tensions simmer underneath. Lomax announces that additional security has been arranged, revealing Superintendent Battle’s presence at the estate. When Dr. Matip finally arrives, he is recognized as the survivor from Ronda. His past, including his service during the war, makes him an uneasy guest among the British elite.
During dinner, Matip reveals his invention: a pocket watch encased in an advanced metal alloy. When Oswald Coote impulsively fires at it, the casing remains intact, confirming its military value and the reason Seven Dials wants control of it.
Sensing danger, Bundle, Jimmy, and Bill agree to keep watch that night. Bundle slips outside to monitor the grounds but is intercepted by Battle, who escorts her back inside. When she returns, something is wrong. Bill and Jimmy are missing.
Locked inside her room, Bundle hears a struggle and then two gunshots. When the door is finally forced open, she rushes to the window and finds Jimmy dead. Another body has fallen, and Seven Dials has claimed yet another victim.
The episode ends with the threat fully exposed. What began as a cryptic phrase has revealed itself as a lethal conspiracy operating at the highest levels, and Bundle is now more deeply entangled than ever.
Episode 3 – The Finger Points
The final episode opens with a brief return to Bundle’s childhood, revisiting the day of her brother Tommy’s funeral. As a young Bundle studies her father’s watch, its design lingers just long enough to echo what viewers now recognize as the Seven Dials motif. The moment quietly reframes the mystery, suggesting that this story has been unfolding far longer than Bundle ever realized.
Back in the present, the episode immediately undercuts the shock ending of Episode 2. Jimmy has been shot, but he is alive. He tells Bundle that a masked man attacked him and escaped through the window, confirming that the violence at Wyvern Abbey was staged to look final, but was never meant to be.
Attention quickly turns to Dr. Matip, whose room Battle and Bundle rush to investigate. Matip is alive but incapacitated, drugged with a sleeping draft. More importantly, the watch containing his revolutionary invention has been stolen from the safe. What had appeared to be a murder now reveals itself as a carefully timed theft.
As the remaining guests are gathered, Battle takes control of the abbey. He announces that someone has been found on the grounds who was not meant to be there. Lorraine Wade emerges, claiming she arrived because she felt uneasy about Jimmy. Her explanation raises immediate suspicion.
Moments later, Oswald Coote produces a gun he claims to have found outside. From here, Battle begins to dismantle the night’s events piece by piece. Guests are ordered to remain in their rooms while he reconstructs the crime.
The situation grows more surreal when George Lomax ignores Battle’s instructions and instead proposes marriage to Bundle. She panics, sends him away, and escapes through her window to find Battle examining footprints in the grass. There is only one clear set. Bundle points out something Battle has already noticed: the gun Oswald “found” was thrown from a window. The distance it traveled suggests it was tossed by a woman.
As Battle continues laying out his deductions, the group fractures. Lorraine disappears under the pretense of searching for a missing earring. Battle presents further evidence, including a burned glove and two bullets, one fired from Jimmy’s gun and the other from Oswald’s. When Oswald is asked to recreate how he threw the weapon, the distance doesn’t match, confirming the deception.
With Lorraine now missing, the investigation turns into a pursuit.
It is soon revealed that Lorraine stole Dr. Matip’s watch and was responsible for Gerry Wade’s death. She attempts to flee by train, but Bundle, Jimmy, and Bill give chase. Along the way, Bill separates himself from the others, revealing he is armed.
At the station, tensions finally erupt. Lorraine admits to killing Gerry, believing he was closing in on the truth. But as Bundle questions her further, cracks appear in the story. Lorraine’s train ticket reveals she was only traveling one stop. The escape was never meant to be permanent.
Under pressure, Lorraine reveals the truth: Jimmy was the architect of the plan.
Jimmy turns on them, pulling a gun and admitting that he killed Ronny and orchestrated the theft as a distraction to obtain Matip’s formula. In the ensuing struggle, Bill is shot, and Jimmy attempts to kill Bundle. The bullet is stopped only because Bill is holding Matip’s watch.
Bundle fires back, forcing Jimmy to flee. She then compels Bill to help stop the train before the conspirators can reach their rendezvous.
The final revelation comes when Bundle confronts Jimmy again. He insists he did not kill Gerry and claims the true mastermind is in the first carriage. Bundle pulls the emergency brake and rushes forward.
There, she finds Lady Caterham.
Lady Caterham admits to orchestrating the larger operation. While Lorraine acted independently in killing Gerry, Lady Caterham planned the theft of the watch and the deaths that followed. Her motive is rooted in grief and fury. She believes England sacrificed her son during the war and left her family with nothing, including no way to save Chimneys from financial ruin.
Bundle is devastated. She reminds her mother that she is still alive, still here. Lady Caterham admits she underestimated her daughter but insists that survival left her no other choice.
When Lady Caterham prepares to escape, Bundle raises her gun. She cannot kill her mother, but she will stop her. Before she has to act, Battle arrives, ending the standoff. Lady Caterham, Jimmy, and Lorraine are arrested.
In the aftermath, Dr. Matip signs his agreement with the British government, placing his invention under official protection.
But the story does not end there.
Back at Chimneys, Alfred arrives with a message from the Seven Dials. Bundle is taken once again into the hidden chamber of masked figures. This time, she demands answers. When the seventh figure removes his mask, it is Battle.
Battle reveals the truth: the Seven Dials are not assassins, but a covert alliance working to prevent global catastrophe. They were attempting to stop Jimmy and Lorraine, not aid them. Bundle’s father was one of their operatives, and his death in Spain was part of a mission gone wrong. Battle was there.
Now, they want Bundle.
Battle does not offer her a choice. He tells her she is needed for what comes next.
Bundle’s response is simple.
“Tell me everything.”
