Death In Paradise ‘Music of Murder’ GEM 21:10 Tues May 10 is a repeat, but isn't flagged as a repeat by the IceGuide.
‘Music of Murder’ S1 E7 was made in 2011.
The IceGuide synopis is also wrong.
The IceGuide synopsis "DI Poole has a bout of tropical fever, and Camille is in Paris, leaving Dwayne and Fidel to solve the murder of a diver, under the stern, unfriendly - and not particularly clever - eye of DS Angela Young." matches the Wikipedia synopsis for ‘An Unhelpful Aid’ S1 E6: "Dwayne and Fidel have to solve the murder of a diver while Poole is ill, Camille is away, and their substitute inspector proves difficult to work with." (apart from disagreement about the rank of the substitute detective).
The Wikipedia synopsis for ‘Music of Murder’ S1 E7 is: "A band member is murdered at the band's comeback gig."
The NineMSN online guide has the episode as ‘Music of Murder’ and a synopsis that matches the Wikipedia one. They also say it's a "New Episode", but AFAIK, the ABC is fully up-to-date with broadcasting all of the Death in Paradise episodes. IMDb says that there are currently no new episodes to show. They foreshadow new episodes in 2017.
