Derry Girls' Siobhan McSweeney will also be making an appearance, as will actress Hakeem Kae-Kazim.
McSweeney will be known to Channel 4 viewers as the actress who plays Sister Michael.
Elsewhere, TV legend Les Dennis has also joined the show.
Meanwhile, former Death in Paradise star Ben Miller recently teased another return to the series as DI Richard Poole.
Miller starred in series one and two of the show. However, fans were devastated when he was killed off at the start of season three.
"Yeah, of course, I would. It was wonderful to come back. I did come back as my character in season 10 earlier this year," he told Radio Times.
The actor said that if his character can return as a ghost then there is a possibility that he could return again and he would jump at the chance to do so.
"I came back as a ghost, so I guess anything is possible. Don't you worry, I'll be struggling into that wool suit. I'll be in that wool suit before you can say Harry," said Miller in reference to Harry the beloved CGI lizard – a series regular.
Death in Paradise airs on BBC One, and the spin-off Beyond Paradise is currently in production.
