The Marlow Murder Club Season 3 Finale Ending Explained: Who Killed Ferdy and Cal?

Spoiler Warning: This article contains major spoilers for The Marlow Murder Club Season 3, Episode 6, “An Appetite for Murder: Part Two.”

The Marlow Murder Club Season 3 finale reveals that Nicki murdered both chef Ferdy Blake and her husband, Cal. The October 11 episode brings Judith Potts, Suzie Harris, and Becks Starling’s investigation to a close, exposing a secret gambling operation, £300,000 in winnings, and a betrayal that connects both deaths.

Who Killed Ferdy Blake and Cal in The Marlow Murder Club Season 3?

Nicki is responsible for both murders, although Ferdy’s death was never part of her original plan. She intended to kill Cal after discovering he was preparing to abandon her and escape to Australia with his gambling winnings.

The mystery begins with Ferdy’s murder at Gastronomy, where someone stabs the chef with his own knife and leaves a £50 note pinned to the weapon. The investigation grows more complicated when Cal is discovered dead inside the restaurant’s walk-in freezer.

Judith eventually discovers that Cal died from suffocation after someone used liquid nitrogen and disabled the freezer’s ventilation system. The evidence confirms that someone deliberately arranged his death to resemble an accident.

As detailed in WTTW’s finale recap, the investigators uncover the connection between the restaurant’s gambling activities and both murders.

Why Did Nicki Kill Her Husband and Ferdy?

Cal had won £300,000 through illegal gambling and secretly planned to move to Australia without Nicki. The couple had dreamed of moving there together since marrying at 18, making his betrayal particularly painful.

Nicki discovers his plans after finding a secret phone in his car. Messages reveal that Cal has already purchased a flight and informed his brother in Australia about the money.

She initially approaches Cal intending to kill him, but Ferdy unexpectedly witnesses her with the knife. Nicki immediately stabs Ferdy to prevent him from exposing her intentions.

She later returns to Gastronomy and kills Cal while he is working alone, using liquid nitrogen to suffocate him inside the freezer.

How Does Judith Catch Nicki?

The breakthrough comes when Judith and her friends discover that Cal concealed his winnings in Gastronomy’s cellar.

A glove found near the river also becomes important evidence. Nicki had travelled to the restaurant by paddleboard, allowing her to approach and escape without drawing attention.

When Judith searches for the hidden money, Nicki traps her in a room. Judith persuades her to leave with the cash, knowing the police are waiting outside.

The confrontation finally brings the investigation to an end and exposes the financial desperation and betrayal behind both deaths.

What Happens to Judith, Darius, and the Others?

The finale closes several personal storylines alongside the murder investigation.

Isla reopens Gastronomy and acknowledges that Ferdy’s successful recipes originally belonged to Omari’s father, whose work Ferdy had stolen.

Meanwhile, Becks finally gets relief from her demanding mother-in-law Marian, who leaves for France with Matthew.

Judith also makes an important personal decision. After initially rejecting Darius’s romantic interest, she changes her mind and agrees to pursue a relationship with him.

The ending gives Judith a fresh chapter in her personal life while preserving the friendships that have shaped the series.

Will The Marlow Murder Club Return for Season 4?

Yes, The Marlow Murder Club has already been renewed for Season 4, with production underway according to PBS’s Season 3 announcement.

Season 3 concludes its central mystery without leaving Nicki’s crimes unresolved. However, Judith’s developing relationship with Darius and the trio’s continued involvement in police investigations provide room for new stories.

All six episodes of Season 3 are available through PBS, with access depending on location and membership.
