BBC 将播出《重返天堂》，这是一部以澳大利亚为背景的英国收视率最高的电视剧之一《天堂岛疑云》的衍生剧。这部六集系列剧将于明年开拍，由 BBC Studios Productions Australia 和 Red Planet Pictures 为 ABC 制作，并与 BBC 联合制作。《重返天堂》以田园诗般的海滨小村庄海豚湾为背景，讲述了六起扣人心弦、曲折离奇、巧妙绝伦的谋杀案——所有这些都以澳大利亚沿海风景为背景。澳大利亚侨民麦肯齐·克拉克 (Mackenzie Clarke) 似乎是伦敦大都会警察局的金牌女郎——她对侦探工作有着直觉，以能够破获最不可能的案件而闻名。然而，她突然被迫搬回童年的家海豚湾，一个美丽的海滨天堂……也是麦肯齐最可怕的噩梦。六年前，麦克一有机会就逃离了家乡，并发誓再也不会回来，留下了许多未完成的事情和未解答的问题。回来后，她仍然不喜欢这个小镇，海豚湾的人们当然也不喜欢她。事实上，每个人都不希望她待在那里，包括麦肯齐自己。但当海豚湾发生一起谋杀案时，麦克忍不住要好好利用她天才的侦探天赋，尽管她有所保留，但她还是决定要充分利用它，包括与六年前她在婚礼上抛弃的那个男人和解。

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.
