Each episode is its entire own story, like it is its own film or something! It’s pure escapist entertainment and people love to switch on the telly and be in a nice, sunny world – all be it a lethal one – and imagine they’re somewhere else for an hour.”Was it a hard choice to decide to uproot to the Caribbean for a while to film?“It was a bit of a no brainer really, obviously you get to go and film in the Caribbean and I have a few friends who have done the show as guest characters and said they had the best time on it and that’s it really. You pick the jobs that you know you’ll have a great time on where the character excites you and it ticked all the boxes.”Death in Paradise returns to BBC One tonight at 9pm.
