Are you excited for the show's return?
The last season ended one something of an unsure note after Cassie was badly affected by the murderer's true identity in the series - particularly when it is revealed that he is actually a psychopath who has killed many people over the years, and tells them about his crimes with cold indifference. However, it looks like she's found a way back to the job for season four - and we can't wait to find out more!
Sanjeev opened up about filming season four
Sanjeev opened up about returning to film the new season in January 2020. Sharing a snap of himself with Sunny's backpack, he said: "Hello old friend. It's good to see you again. Nice to know you've got my back." He also shared a snap with his co-star Nichola back in November 2019, writing: "Sunny and Cassie sitting in a tree... Catching up with a friend and discussing what might end up in #sunnysbackpack #unforgotten series 4 filming soon!"
