Speaking of the new series actress Reid said: “When we first meet Ophelia she is a student at Cambridge.
“She soon falls madly in love and that love takes her to a very scary place psychologically and soon the world she inhabits starts to become very dangerous.
“Everything is a bit uncanny, you can never quite pinpoint what is wrong but there is constantly something that is not quite right. Eventually, you find out what that is.”
Reid is an up and coming actress, best known for playing Sophia Trenchard in Belgravia and Roxanna Dubiki in The Trouble with Maggie Cole.
Normal People’s Paul Mescal plays Sean McKeogh, Ophelia’s friend at university whom she confides in.
Speaking about his character, Mescal said “Sean is a simple man, in a good sense. He is a man directly invested in the community, he has a very strong and good moral compass and he has his eye on Ophelia.
“He is attracted to her but also there is a slight concern he has for her. Most of my scenes are with Emily, who is phenomenal in this and she is a wonderful person and was very kind and generous with her time.”
Little Women’s Eleanor Methven plays Roisin’s mother, Mary Mulvey alongside Derry Girls star Ian McElhinney who stars as Michael’s father Hugh.
Liar’s Shelley Conn stars as Roisin’s best friend Ruth opposite, Patrick Melrose’s Dempsey Bovell portrays Matthew’s close friend.
In a statement, writers McGee and Beer said “We always had a ‘dream cast’ in mind when we began working on the show, but never imagined we would end up with them actually on board.
“With the brilliant Chloe Thomas directing, we are thrilled to have the story in such gifted hands.”
The Deceived airs weeknights at 9pm on Channel 5, concluding on Thursday, August 6
