If there are backstories connecting with previous episodes I may have to rewatch before starting on the new series.
Should I do that *Calendargirl?
My memory has got worse of late. An advantage in lockdown as I was able to reread lots of books as I had entirely forgotten (lost) the plot.
You don’t have to watch the previous series really, just need to know that Nicola Walker’s character has been on long term sick after dealing with traumatic cases for years, and feeling she needs to give victims families closure, but you probably gathered that anyhow.
Re the back stories, in Unforgotten there are always several possible ‘suspects’ with hidden histories behind them, and somehow connected up with each other.
