Shetland: Season Four - Episode Six

Perez: 'Christ, Rhona. Do you think I want this to be happening?'

When the closing credits started to roll, I thought to myself: well, at least I guessed one of the killers. After some honest contemplation, I was forced to admit that the only reason I guessed who killed Lizzie was because at some point I've suspected everyone: Duncan, Drew, Kate... even Curly Haired Jigging Woman and Beardy Extra. So kudos to David Kane for writing a script that kept us guessing till the end, and then kicked us up the arse for daring to believe in justice.

Shetland: Season Four - Episode Five

Sandy: 'Jo, can you remember who did this to you? Was it Thomas Malone? Was it your ex-husband?'

Sandy finally managed to ask some sensible questions this week, only to be scuppered by Jo's knackered throat and the old witness-out-of-commission ploy. At least we know who gave Jo a mullering, although we're still in the dark as to whether she has any deeper involvement in the story. After the appearance of her shady can't-tell-the-truth-for-shit husband, I'm guessing so, but it was nice to see a cliffhanger with consequences.

Shetland: Season Four - Episode Four

Perez: 'Nobody's better off dead.'

If last week's sinister music, sombre faces, and speeding vans were anything to go by, Tosh and Jimmy should've been in the shit tonight. Spoiler alert: nothing dramatic happened. I may have been wrong about the vans' occupants being disreputable halibut salesmen, but the truth was only marginally less fishy: it was simply the local constabulary wanting a chat. Stay tuned to see this week's cliffhanger explained away as Jo slipping on a banana skin and knocking herself out on an inconveniently placed easel.

Shetland: Season Four - Episode Three

Perez: 'This isn't your case any more. You had your chance over twenty-three years ago, and you blew it.'

I was ready to dislike this week's episode. For me, Shetland is at its best when it's telling parochial stories about island folk, so I wasn't sure the temporary shift to urban far-right politics would work. Turns out my concerns were unfounded: as well as providing some lovely scenery, the coldness and remoteness of the Nordic countryside were a great tonal match for the subarctic archipelago.
