The cast features a mix of white leads (Ardal O'Hanlon as DI Jack Mooney) and black/Caribbean supporting characters (Don Warrington, Tobi Bakare, Shyko Amos), which aligns organically with the multicultural island setting rather than forced DEI mandates or identity politics swaps. Episode plots revolve around classic whodunits—like murders during elections, on luxury trains, or involving billionaires—with zero evidence of lectures on systemic racism, patriarchy, gender fluidity, or social justice activism.

There are no creator statements emphasizing inclusion quotas, no race/gender/sexuality alterations clashing with source material (as it's an original series), and no audience backlash labeling it 'woke' or citing politicized elements; reception focuses on entertainment value, plot predictability, and character charm. Any diversity present is incidental and unobtrusive, allowing the show to prioritize pure escapist fun without compromising narrative quality.
