Royal family member Lady Frederick Windsor, who is also known as Sophie Winkleman, starred in season nine episode one, Five Little Pigs, back in 2003 - but do you remember seeing her?
WATCH: Sophie also starred in The Lion, the Witch and the Wardrobe
In the episode, Sophie plays Angela Warren, one of the 'five little pigs' who was present at the house during the murder of artist Amyas. While his wife was found guilty of the crime, her daughter Carla begs Poirot to take the case as she is determined that her mother is innocent.

Sophie starred alongside Game of Thrones star Aidan Gillen and Bridget Jones's Diary actress, Gemma Jones in the episode, who played Amyas and Miss Williams respectively.
Sophie tied the knot to her royal husband Lord Frederick Windsor back in 2009, and the pair share two children, Maud and Isabella. Speaking to Tatler about being unable to work back in 2020 due to the lockdown, she said: "It's been alright, but I've been frustrated and tired and stressed out like everyone else.
She starred in the episode titled Three Little Pigs
"Children need to socialise and they get extremely bored if they don't, and I've not been covering myself in glory with this online learning thing... The teachers have been really brilliant, but I've been loath to stick my six-year-old in front of a screen all day long."
