Shetland - Series 1-6 (DVD)

Originally created from the novels by award-winning writer Ann Cleeves (Vera, The Long Call) and set against a hauntingly beautiful landscape, Shetland follows DI Jimmy Perez (Douglas Henshall) and his team as they investigate complex crimes within a close-knit island community.

In this isolated and sometimes inhospitable environment, the team must rely on a uniquely resourceful style of policing to unpick the truth. Series one and two are based on bestselling books Red Bones, Raven Black, Dead Water and Blue Lightning. Each subsequent instalment focuses on an original single mystery written for television, each told over six gripping episodes.

Series three sees Perez tackling a conspiracy that takes him back to the Scottish mainland in a case that will exact a terrible personal toll on both him and his team. Perez faces murders from the past and present with unsettling similarities in series four, when an investigation leads him closer to home than he could have ever imagined.

Series five sees a gruesome discovery wash up on a beach, leading to a disturbing case that reaches far beyond the islands' shores. In the latest series, secrets from the past rise to the surface once more after a prominent Shetlander is shot dead on their doorstep in broad daylight.
