The final episode of the BBC’s adaptation of Towards Zero brings the mystery at Gull’s Point to a dramatic conclusion. The lavish South Coast estate of Lady Tressilian has been at the center of a tangled web involving tennis player Nevile Strange, his ex-wife Audrey, and his current wife Kay.
Other notable guests include lawyer Mr. Treves, Lady Tressilian’s companion Mary, Nevile’s cousin Thomas Royde, and Inspector Leach, each with their own secrets. As expected in an Agatha Christie tale, the suspense builds gradually before the murders unfold.
A Suspenseful Journey from Potential Killers to a Shocking Murder Revelation Unfolds
Director Sam Yates described the series as initially a “who’s going to do it” before evolving into a classic “whodunnit.” Before any crime takes place, viewers are left guessing who might commit murder, as every character seems to have a possible motive. The tension escalates with subtle hints and interactions, making the ultimate reveal all the more satisfying. The deaths of Lady Tressilian and Mr. Treves set off a chain of revelations, exposing long-held grudges and hidden betrayals.

Inspector Leach pieces together the mystery after a revealing tennis match with Nevile. It is discovered that Audrey had planted evidence against Nevile to push for a divorce, enraging him. Driven by revenge and a desire to inherit Lady Tressilian’s estate, Nevile murdered his aunt before she could alter her will.
He meticulously crafted an alibi by making a public appearance at Easterhead, appearing to be too far away to commit the crime. However, Leach uncovered an old photo of Nevile as a skilled swimmer, proving he could cover the distance without detection.
Nevile’s Deception Unraveled Betrayal Justice and the Final Reckoning at Gull’s Point
Nevile went to great lengths to frame Audrey, even planting her makeup on his jacket to shift suspicion onto her. When an innocent man, Matthew Hutton, was wrongly arrested for Lady Tressilian’s murder, Nevile felt compelled to kill Mr. Treves to further solidify his deception. Ultimately, Audrey revealed the long-kept secret that linked Nevile to the death of Peter James, further damning him. His actions not only cost him his freedom but also destroyed his standing among those closest to him.
In the end, justice prevails as Nevile is sentenced to hang for his crimes, while Audrey is finally free to start anew. Inspector Leach takes guardianship of Sylvia, forming an unexpected bond after the chaos. As with any Agatha Christie masterpiece, the resolution ties together various red herrings and intricate plot twists, leaving audiences satisfied with a well-earned revelation. Towards Zero proves itself to be a gripping adaptation, keeping viewers on edge until the very last moment.
