Season 4 of UK mystery Shetland will air on ABC this Sunday.
This screened in the UK in February 2018 (where a 5th season recently aired).
There are 6 episodes all up.
A detective mystery set against the stunning Scottish backdrop of the Shetland Isles. Shetlander, Thomas Malone, has his conviction overturned after 23 years behind bars, DI Jimmy Perez (Douglas Henshall) must re-open a murder investigation. In 1993, teenager Lizzie Kilmuir was found strangled and placed in a stone cairn on the island of Unst. Malone, then only a teenager himself, was jailed for the crime. Now new DNA evidence has come to light provoking Malone’s release, but many islanders still believe him to be guilty, including some officers amongst Perez’ own team. Malone’s return coincides with the murder of local journalist Sally McColl. Sally is the daughter of the detective who originally investigated Lizzie Kilmuir’s murder and was responsible for having Malone convicted. With two cases to solve and Malone very firmly in the frame for both, the pressure is on Perez to look beyond the gossip and prejudice and get to the truth.
7:40pm Sunday on ABC.
