BBC Shetland fans 'work out' who killed Annie after spotting major clue

by · DevonLive

Viewers of Shetland have been left on the edge of their seats, piecing together clues that they believe point to the killer of Annie.

Annie's sudden disappearance had already set alarm bells ringing for her concerned friend Tosh (Alison O'Donnell), as Annie was eager to discuss an unspecified matter with her. The situation took a dark turn when Tosh discovered Annie was nowhere to be found the following morning.

The plot thickened with the grim find of Annie's body at a construction site owned by her estranged husband Ian, alongside another casualty, Anton Bergen. Meanwhile, Noah, who narrowly escaped the scene with blood-stained clothing, sparked fears that he might have witnessed his mother's demise.

The second episode, aired on Wednesday, threw viewers a curveball as it delved into Annie's history. Her university days at 15 and a penchant for mathematics led her into the clandestine world of espionage, with Professor Euan Rossi also implicated.

This fresh revelation has fans buzzing with theories, with some now convinced they've cracked the case of who is behind Annie's murder, reports the Daily Record.

One viewer speculated on social media: "Professor to kidnap Noah next? #Shetland," while another chimed in with a theory about familial connections: "Noah is definitely the professor's son. That's prob why the dad keeps going off on benders #shetland."

However, another avid viewer of the show has a different theory about Annie's death. They shared their thoughts on social media: "My thoughts on #shetland I'm guessing the daughter who is 'ill' and was cared for by Bergen, doesn't actually have any illness. Annie Bett was there the day Bergen confronted the parents and she was killed in the crossfire. It's munchausen by proxy (induced illness)."

Alison O'Donnell, who portrays Tosh in the series, admitted her excitement over the plot twist.

In an interview with Radio Times, she expressed: "I was really excited [by that twist]. I knew that there was going to be this sort of MI5 element before I'd even read the script, and I thought that's really cool."

"I was in the middle of reading the Richard Osman books at the time, so I was like, 'Oh, I know all about this.' And I think it's really fun territory because you get so much for free with that one. All these people are professionals at skullduggery, so there's so much to be mined there."

*Shetland airs Wednesdays at 9pm on BBC One and BBC iPlayer.
