Death in Paradise series 15 – one of our favourites so far – continues this week with episode 6 and another great guest cast of famous faces.

This week, Mervin goes in search of his brother Solomon on Antigua, but stumbles into a crime scene… In a remote cabin, a local businessman has been shot. But Solomon and his associate Cheech both swear the other is responsible. And they’re not letting Mervin go until each one has convinced him of their account.

As DS Thomas and Commissioner Patterson realise Mervin could be in danger, they follow in pursuit. Until irritating Sterling Fox returns and tries to throw his weight around…

Here’s everything you need to know about the Death in Paradise guest stars joining the cast in episode 6 of series 15.
