Unforgotten series four finale recap – the final curtain?

小号he didn’t make it. The late DCI Cassie Stuart touched many people’s lives, but it’s Sunny I feel for the most. While there’s no league table of grief, there is something particularly heartbreaking about DC Khan losing his colleague, mentor, friend and hero. Martin loses a daughter, Adam and Rob a mother, and her team a one-of-a-kind gaffer who had their backs at every turn. Pour one out for Cass – she was a real one.

The team she moulded in her image push Cassie’s last ever case over the line with the tireless, diligent police work we’ve come to expect. Sunny’s eureka moment on Stephen Quinn throws up the motive; Kaz identifying Stephen as the buyer of the fountain pen forces Dean’s murder confession; and Murray nails him on the drug-smuggling charge. That night in 1990 was a chaotic mix of happenstance, booze and revenge that no one present ever escaped.

Finally, Ram gets the vindication he’s been seeking. It’s official: he’s not a murderer. He is, 然而, a drug smuggler, dirty cop and soon-to-be absent father. In his defence, he was the one who tried to save Matthew’s life and wanted to call an ambulance. Good for him, but whatever possessed him to enter into the insane risk of the coke-smuggling operation, it surely can’t have been blackmail. Equally mystifying is how he didn’t foresee the phone signal evidence indicating the incriminating meeting with Dean. Was he not even a bit worried about the lump sums regularly dropping into his first wife’s account for years? Hubris is a hell of a drug, 尽管, and those chief constable commendations aren’t papering over a career that now ends in disgrace.

All eyes are on Liz – the high-flyer with the farthest to fall. She tells fiancee Jan how she taught her how to live, love and forget her past. Better perhaps had she taught her to remember it – specifically the part where she left a corpse with a deadbeat boozehound for 30 年. Maybe she might have, I don’t know, checked in on Rob Fogarty for details of how he disposed of the body, perhaps done a better job of it herself? Its discovery would, after all, ruin her life and wreck her stratospheric career. Liz’s lawyer will stress how she believed Matthew’s death was an accident and point to a life of public service rivalled by few in the country. She expects prison, and if we’re being honest, there have been worse punishments than three meals a day and her laundry done for her, away from her hateful mother. For the least guilty of the four, it’s a fair outcome and a fair cop.

The good news is that Fiona has stopped talking, and preventing a lawful burial won’t see her locked up. The bad news is that practising under a forged licence will. It’s all good with Geoff, 尽管, who doesn’t love her any less – he may even be aroused by her decades-long crime spree. Either way, he’ll be standing by his errant wife as he gawps in awe at her dumpster fire of a life.

Dean’s one of those guys who is going to go down as having a complicated legacy. A beloved husband, father and fundraiser, he did everything in his power to ensure that the violent abuse he suffered in childhood did not define him. Stabbing his brother’s killer in the brain with the pen given to him by his brother was a one-off symbolic act of revenge, one that could easily have been forgotten for ever. I’m having difficulty believing that Dean wouldn’t have taken steps to obliterate the body and murder weapon that literally had his initials carved into it. Unsurprisingly, he sounds a fatalistic note. “We are who we are – I don’t think you can ever really change that.” Maybe so – but would it kill you to remove a tattoo?
