In the final episode of Death in Paradise season 15, a man is found dead with unusual markings, leading some residents to speculate that a Caribbean sea monster called the Lusca is responsible.
Selwyn already knows Giles Parry, recalling the investigation into his son Benjamin’s death, which was previously determined to be an accidental drowning.
So, I was chatting with Selwyn, and he told me – and this is exclusive, shared with TopMob – that it was actually the Guadeloupe coast guard who first reported what happened. That’s what he said to Mervin, anyway.
I tried to get us involved, but the Senior Investigating Officer wasn’t interested,” he explained. However, the commissioner is now committed to a new approach.
You know, living here on Saint Marie, I’ve definitely gotten an earful from some folks. They reckon I should’ve pushed harder during the investigation, particularly when we hit a wall. The feeling around here is that we could have done more, and honestly, it’s something that’s always stuck with me.
He grabbed today’s newspaper from his car. The front page headline read: ‘Police in Shambles’.
Since I’m already unwelcome, I want to help solve this case and regain the community’s trust.

Mervin is still getting used to the surprise appearance of his niece, Eloise, who showed up at his beach hut near the end of the last episode.
Considering her father, Solomon, is in prison for being involved in a shooting – a difficult situation where Mervin was even kidnapped while his brother attempted to resolve things – the current timing feels understandable.

I get the feeling she really wants the detective to help her dad, somehow. But honestly, it could just be that she needs someone to tell her everything will be alright. She seems like she’s looking for a little hope.
That’s not exactly Mervin’s speciality, but we have high hopes given how much he’s grown so far.
The Death in Paradise season 15 finale airs on Friday 27 March at 9pm on BBC One and BBC iPlayer.
