The Chelsea Detective – Season 1 Episode 4 1

Max and Priya are enlightened by forensic expert Ashley Wilton about the gruesome details of Oliver's demise. The fatal blows, inflicted by a heavy object with a square edge upon his head multiple times, transpired sometime during the late hours of the previous evening. Notably absent is both the murder weapon and any signs of forced entry, yet the brutality of the attack suggests a crime fueled by intense anger. Lyn, arriving late from a nocturnal yoga class, refrained from disturbing Oliver, who she found engrossed in his study.

Despite a recent incident where neighbors called the police due to a loud altercation between Lyn and Oliver, suspicions against her as the perpetrator seem unfounded. Her suspicions of Oliver's infidelity and her profound dismay over his acceptance of a position in Japan, defying their shared promise to remain in beloved London, weigh heavily on her. Furthermore, their daughter Flo (Tia May Watts) was spending the night at her best friend Petal Fisk's (Libby Mai) house, adding another layer to the intricate tapestry of the night's events.

Outside the Cowies' residence, two members of Max's team grapple with inquisitive neighbors and passersby, while Connor adroitly intercepts Carmel Fry (Tilly Vosburgh), the devoted housekeeper who has been an integral part of the family's life in London for eight years. Distressed by the impending relocation to Japan, Carmel's demeanor reflects her deep connection to the family. Forensic analysts scrutinize dust on the study mantelpiece, revealing that an item is conspicuously absent – a debating team trophy, identified by Carmel herself.

The absence of CCTV cameras outside the premises complicates matters, with neighbors' testimonies yielding only a solitary clue: a bicycle parked against the exterior wall on the night of the murder. Meanwhile, Max ponders over an unexpected early morning visit from his ex-wife Astrid, who reprimanded him for neglecting the plant she had gifted him and lambasted his living conditions as akin to student squalor. Seeking validation, he poses this question to Priya, who, less than enthused about the houseboat, looks at him askance and attempts to offer a considerate response.

Their investigation delves deeper with a visit to the school, where they meet Head Teacher James Green (Alexander Hanson), freshly returned from a trip to Brussels. He reassures them that Oliver was well-liked by everyone. However, James's dismissive remark about "estate kids," a derogatory term for children from low-income families living in public housing, does little to endear him to Priya. Their attention is inevitably drawn to a skillfully crafted graffiti of a vibrant, multicolored rooster adorning the school's exterior, signed by Deadwood Price and adorned with the haunting motif of a dangling spider. Max, adept at deciphering codes and hidden meanings, recognizes the signature as an anagram for "Drop Dead Cowie," hinting that Oliver may have had adversaries contrary to James's assertions.

Examining Oliver's phone, they discover he had deleted an apology from Saskia Turner, the last person to see him alive as he left work. Saskia, who was busy grading students' assignments at home on the night of the murder, reveals that Oliver had once driven her home inebriated, and she had attempted to kiss him. Oliver had been her staunch supporter in a sexual harassment case against James.

Despite Oliver's office being sealed off with police tape, they find James has defiantly broken the seal and is rummaging through its contents. His defiance wanes when confronted with their knowledge of the sexual harassment case and his lie about his Brussels trip. James admits he was searching Oliver's office for evidence to aid his defense in the harassment case. He claims to have spent the evening walking and later enjoying a pint outside a pub, a claim supported by the timing but unverified by lack of CCTV footage. They conclude that, logically, he wouldn't have had sufficient time to travel to the Cowies' house, commit the murder, and escape undetected, covered in blood. James's next police interview will take place at the station, where he will be accompanied by legal counsel.

With assistance from the school's Pastoral Care department, focused on student welfare, Max and Priya cast a wider net. They uncover that student Eric Heidegger (Jeremias Amoore) had a confrontation with Oliver, leading to a suspension notice issued on the day of the murder. Eric had spray-painted "Cowie is a cock" on a school door.

Upon visiting Eric's house to speak with his father, they encounter Eric returning home. Upon seeing the police, he flees. Connor pursues him on foot, while Jess follows in a car, expertly cornering him.

In an in-depth conversation with Max, Eric accused Oliver of setting him up by planting a can of paint in his backpack, fully aware of Eric's alias, "Deadwood Price." Max found himself inclined to side with Eric, but the question lingered: why would Oliver jeopardize his career by framing a mere student? Eric had a straightforward answer. Oliver had discovered that Eric and his daughter Flo had rekindled their romance. Their relationship had once blossomed, until Oliver accused Eric of drug procurement and banished him from their household. Eric insisted that he was home on the night of the murder, yet his alibi was somewhat shaky: his mother retired early, while his father embarked on an evening jog.

An exhaustive examination of Oliver's computer unveiled an encrypted, anonymous email containing a snapshot of Eric and Flo enjoying each other's company at school. Max's proficient team swiftly traced the origin of the email to James, the headmaster of their prestigious school, whose actions were nothing short of questionable. It was also revealed that James had been searching Oliver's office for this incriminating photo.

The investigative team also sought out Rory Fisk, Petal's father and a hospital employee, who stood out as an unconventional parent in the International School's community. Regular substantial transfers to his account from Oliver sparked suspicion—was it blackmail? Rory confessed that Oliver had been footing the bill for Petal's education after her scholarship expired, believing that Petal's positive influence could benefit his daughter Flo. However, Rory harbored concerns about Flo's erratic behavior, secretly relief-stricken when the Fisk family prepared to relocate from London. Rory's job required him to work nights, but on the night of the murder, he took an uncharacteristic two-hour break, during which he visited his girlfriend, keeping this encounter a secret from emotionally fragile Petal.

Furthermore, a helpful neighbor, who was out walking his dog that evening, informed the police that he witnessed Oliver answer the door to a tall, Caucasian man clad in a sweatshirt adorned with a cross on the back. Max and Priya then interrogated Eric's father, Alex Heidegger, who candidly admitted to visiting Oliver to negotiate on Eric's behalf. Eric's expulsion would deprive him of the crucial final exams. The discussion was emotional yet civilized, and Alex corroborated his story with CCTV footage and credit card receipts from a corner shop he visited afterward. Perhaps most crucially, he wasn't covered in blood. Additionally, he mentioned encountering a girl cycling towards the Cowies' residence on his way home.

When Max spoke with Eric again, the latter fervently defended his father. Eric insisted that he was out tagging with Flo on the night of the murder, with Petal covering for them. Aspiring for an art school education, Eric received encouragement from Max, who admired his artistic endeavors.

Housekeeper Carmel once again finds herself in the spotlight of an interview, her heart wounds still raw from Oliver's decision to exclude her from their Japanese journey, ostensibly due to visa qualifications. She considers them family, yet realizes she was seen as expendable. Yet, this revelation does little to tarnish her character with the label of murderer.

Meanwhile, at Flo's abode, sisterly duties clash with wandering thoughts. Petal diligently tackles her homework, while Flo, restless and yearning for adventure, rummages through Petal's closet. A shoebox tumbles open, revealing the long-lost murder weapon, stark and bloody, amid their startled gazes. Just then, Max and Priya arrive, their suspicions about Petal being the cycling figure intensifying, catching the young women in this macabre discovery.

Petal had sought Oliver's mercy, pleading for Flo's safety and a chance to complete her school year under her roof. Oliver, however, dismissed her, urging her to return home and leave his family be. In a blinding fit of anger, Petal's rage led her to commit murder. Priya swiftly contacts the duty officer to apprehend Petal.

Priya then heads home to relieve Nitin of his babysitting duties—poor Nitin, ever the kind and patient soul, growing weary of his domestic confines. He consents to prepare dinner while Priya soothes Poppy into slumber.

Max retreats to his newly tidied houseboat, dialing Astrid's number with a need that transcends mere assistance. He seeks her counsel for Eric's art school application, hoping to convince his father that Eric's true passion lies there. Upon their return to the houseboat, Max reveals his commitment to residing there permanently, his address officially changed. As a gesture, he unveils a new plant nestled in a flowerpot adorned with Eric's intricate spider-on-a-thread design. Though not a reconciliation per se, it marks a step forward in their journey together.
