Tonight's finale promises to be an exciting conclusion to the season, with a new mystery for Detective Mervin Wilson and his team to solve before the series takes a break.

In the last episode of the season, DI Mervin Wilson, played by Don Gilet, and his colleagues have to figure out what happened to a man who spent his life searching for a legendary sea creature.

The body of this eccentric monster hunter is found in the ocean, and the big question is whether the mythical creature he was looking for might have been responsible for his death.

The character of Giles Parry, the monster hunter, is played by actor Toby Williams, who is not only an actor but also a stand-up comedian.

Giles Parry dedicated his life to tracking down the Lusca, a mysterious marine beast, and his body is discovered with injuries that suggest he might have been killed by the very creature he was searching for.

The discovery of Giles' body leaves Detective Mervin Wilson puzzled, and he must now work to unravel the mystery behind the man's death.

Toby Williams, the actor who plays Giles, has appeared in several notable TV shows, including Vanity Fair, Sex Education, and Father Brown, often in minor but memorable roles.

Another key character in this episode is Kelvin Mason, played by actor Alexis Rodney, who has had significant roles in films like Guardians of the Galaxy and TV series such as Pennyworth.

Kelvin Mason seems to be part of the crew that helped Giles in his quest to find the elusive sea monster, based on his appearance and the context of the story.

Actress Claudie Blakley plays the role of Cara Smart, a character whose exact connection to the events of the episode is not immediately clear but is seen speaking to a crowd with a notable figure from the series.

Cara Smart is portrayed by Claudie Blakley, an actress known for her work in various BBC programs, including her role in Pride and Prejudice alongside Keira Knightley.

Claudie Blakley has a diverse portfolio, with roles in Manhunt, Grantchester, and the comedy series Man Vs Bee, showcasing her range as an actress.

The character of Rory Lyons, played by Nicholas Burns, is seen with Cara Smart, suggesting a possible romantic connection between the two, but his link to the death of Giles Parry is still a mystery.

Rory Lyons' connection to the case is unclear, but actor Nicholas Burns brings his character to life with his experience from roles in Nathan Barley, No Heroics, and the popular series Benidorm.

Nicholas Burns has recently appeared in The Serpent Queen and The Girlfriend, demonstrating his versatility in playing different characters across various genres.

Eloise Clarke, played by Avah Cotterell, joins the cast in the finale, arriving unexpectedly at Detective Mervin Wilson's beach hut and turning his life upside down.

Avah Cotterell makes her television debut as Eloise Clarke, Mervin's long-lost niece, who shows up uninvited and moves into his home, causing him uncertainty about how to proceed.

The introduction of Eloise Clarke adds a personal dimension to the story, as Mervin navigates his professional life while dealing with unexpected family matters.

Eloise's father, Solomon Clarke, who is also Mervin's half-brother, returns in this episode, but his intentions and role in the story are yet to be fully understood.

Solomon Clarke is portrayed by actor Daniel Ward, known for his roles in Mood, Everything Now, and A Bird Flew In, bringing depth to the character and the storyline.

As the season concludes, the return of Solomon Clarke adds another layer to the narrative, potentially tying up loose ends or introducing new plot threads.
