The sun-soaked island of St Marie has just got a whole lot more star-studded. 

BBC1's Caribbean-set crime drama Death in Paradise is welcoming a wealth of famous faces to guest star in its upcoming fourth series. 

Harry Potter star Matthew Lewis is set to swap the potions and herbology at Hogwarts for a spot of crime solving, alongside Neil Morrissey, Sally Phillips and James Fox. 

Soap stars Jason Merrells and Michelle Collins are also poised to appear on the drama, as are Francis Magee, Nick Moran, Colin McFarlane, Jo Absolom and Gary Lewis. 

The newly announced guest stars are joining an already packed cast list that includes Natalie Gumede, Hetti Bywater, Leo Staar and Amy Nuttall. 

Death in Paradise, starring Kris Marshall, Sara Martins and Danny John-Jules, follows British DI Humphrey Goodman as he solves murders in the Caribbean crime hot spot. 

Death in Paradise returns to BBC1 in early 2015
