As the fourth episode of "Cleddau/The One That Got Away" unfolds, we find ourselves entangled in a web of suspense, guilt, and the chilling aftermath of a traumatic past. The episode, aptly titled "Chapter 4," delves deeper into the murder investigation of Abbi Rayner, with Mel Owen emerging as the prime suspect. However, the waters are far from clear as detectives Rick and Ffion grapple with their own demons and the enigmatic past of their suspect.

Mel Owen, portrayed by Matthew Aubrey, is a character whose past is as haunting as the crime he's suspected of committing. The episode reveals the depths of his abuse at the hands of his father, Paul Harvey, a dark secret that has festered for 12 long years. This revelation adds a layer of complexity to Owen's character, making him both a victim and a potential perpetrator in the eyes of the viewers.
The detectives, Rick and Ffion, are at odds over Owen's involvement in the historic murders. Rick, played by Richard Harrington, is convinced of Owen's guilt in Abbi's murder, citing the discovery of her scarf in his cabin as concrete evidence. Ffion, on the other hand, portrayed by Elen Rhys, is more cautious, her doubts fueled by the lack of concrete evidence linking Owen to the older crimes.
The episode is a masterclass in character development and storytelling. It expertly weaves together the personal and professional lives of the detectives with the harrowing tale of abuse and murder. The tension between Rick and Ffion is palpable, especially when Ffion returns to her parents' house to find her father reminiscing over their engagement photos. This personal subplot adds emotional depth to the episode, providing a stark contrast to the cold brutality of the crimes being investigated.
The narrative takes a dark turn when Ryan Moss files a complaint against the detectives, alleging coercion into a confession. This development not only puts Rick and Ffion's careers at risk but also their partnership, as they begin to question each other's judgment and the integrity of their investigation.
As the detectives press on, they uncover more about Owen's past, including his time in the attic on the night Sian Hinton was killed. This discovery leads to a tense interrogation where Owen's agitation and cryptic responses only serve to deepen the mystery surrounding him.
The episode reaches a climax when Ffion visits Anna Jennings, who reveals the location where Paul Harvey used to lock Owen up as a child. This chilling revelation leads Ffion to question whether Owen could have escaped and moved Sian's body himself, a theory that is further complicated by Alex Hinton's inconsistent accounts of the night his wife was murdered.
The episode concludes with a shocking twist as Owen, unable to bear the weight of his past and the accusations against him, takes his own life in prison. This tragic event not only marks the end of one storyline but also sets the stage for a deeper exploration of the characters' emotional turmoil and the lingering questions about the truth behind the murders.
"Chapter 4" of "Cleddau/The One That Got Away" is a gripping installment that keeps viewers on the edge of their seats. It is a testament to the show's ability to balance intricate plotlines with emotional resonance, leaving us eager for the next chapter in this gripping tale of love, loss, and the relentless pursuit of justice.
