　　The BBC will air Return to Paradise, a new Australia-set spin-off from one of the UK’s most watched dramas Death in Paradise. Filming next year, the six-part series will be produced by BBC Studios Productions Australia with Red Planet Pictures for the ABC, in association with the BBC.
　　Set in the idyllic, beachside hamlet of Dolphin Cove, Return to Paradise is six gripping, twisting and fiendishly clever murder mysteries – all against the spectacular backdrop of the Australian coastal landscape.
　　Australian ex-pat Mackenzie Clarke is the seemingly golden girl of the London Metropolitan police force – with an intuitive approach to detective work, she has built a reputation for being able to crack the most impossible of cases. However, she’s suddenly forced to up sticks and move back to her childhood home of Dolphin Cove, a beautiful, coastal paradise… and Mackenzie’s worst nightmare.
　　Having escaped her hometown at the earliest opportunity six years ago, Mack vowed she'd never come back, leaving a lot of unfinished business and unanswered questions. On her return she’s still no fan of the town, and the people of Dolphin Cove are certainly no fans of hers. In fact everyone would prefer her not to be there, including Mackenzie herself.
　　But when a murder takes place in Dolphin Cove, Mack can’t help but put her inspired detective brilliance to good use and determines, despite her reservations, that she needs to make the best of it, including tying up the loose ends with the man she left at the altar six years ago.
