Saint Marie is a fictional island in the Lesser Antilles which serves as the setting for the BBC crime drama television series Death in Paradise.
Marie-Galante, Saint-Marie, Spinner's Rock (a small islet relevant to this episode), and Saint Robert can be described as being on a straight line between Guadelope and Dominica in that order, from the most northern to the most southern.
In the series, Saint Marie has a volcano and a rainforest, sugar and coffee plantations, a fishing harbour, an airport, a university, a convent, multiple hotels, approximately one hundred public beaches, and a Crown Court.
Saint Marie's main economic ties are to Guadeloupe, the UK, and France, but it uses the East Caribbean dollar as its unit of currency, as opposed to the pound or the euro.
Law enforcement on the island is overseen by the Commissioner of the Saint Marie police force, a role held by Selwyn Patterson throughout the duration of the show.
Whilst the bulk of the Commissioner's time focuses on the investigations of the Honoré police unit, he also has wider responsibilities across the island, such as in towns like Port Royal.
