In the clip, Darlene and Naomi are seen talking about missing Marlon after he left the team in last week's episode, while Neville is distracted on his phone.
The commissioner then arrives bearing bad news, when he reveals that the officer he hired to replace Marlon will not in fact be joining, as they are staying on the Caymans.
Naomi and Darlene then start discussing Neville's love life, deliberating on why Zoe wouldn't have been upfront with Neville about who she was from the start.
Neville tries to get them off the topic by saying the commissioner wouldn't be interested, but as it turns out, he very much is.
As well as seeing the departure of Marlon, last week's episode of Death in Paradise saw the welcome return of one of the show's past stars, Tobi Bakare, back as JP Hooper.
