<P> Often towards the end, the lead DI will have a moment of realisation, perhaps brought on by something that someone says or does or by some occurrence . In this moment, the how, why, and who of the murder are comprehended by the DI, but are not revealed to the audience . The suspects are then all gathered together and the DI talks through the evidence; often, flashbacks are used to show what happened . The murderer and the motive are revealed in the denouement of the episode . </P> <P> Normally, each episode ends with a comedic scene or a celebratory trip by the police force to Catherine's bar . The final episode of most series has included a subplot wherein the lead DI is tempted to return to the UK by the prospect of a job offer or personal relationship, but in the end, he decides to remain on the island . This format was subverted in the sixth series when the two - part storyline in the fifth and sixth episodes saw the team travel to London to follow up on a current case, resulting in then - lead detective Humphrey Goodman deciding to remain to be with his new girlfriend; D.I. Jack Mooney travelled back to Saint - Marie, initially as a holiday, but decided to remain as the new detective inspector of the island in the series finale . </P> <P> Death in Paradise is set on the fictional Caribbean island of Saint Marie, described in Episode 3.3 as a "pretty island" that is "situated in the Eastern Caribbean Sea" and "one - tenth the size of its north - west neighbour Guadeloupe"; this would make Saint Marie about 63 square miles (160 km) in size . Saint Marie is a British Overseas Territory, but about 30% of its people are of French culture due to previous history, with the language still widely spoken . </P> <P> The back - story appears to be a blend of two real - world islands near to Guadeloupe, with size and location aligning with Marie - Galante and history and language aligning with Dominica . </P>
