Viewers who tuned in to watch the latest instalment believe Adam James' character, Jack Owens, is responsible for the murder due to the fact that the actor tends to play "malevolent" roles.
One person wrote: "The actor who's playing Jack always plays baddies, so I guess he's the murderer," while another added: "#TheSuspect enjoying this but the twist has been obvious from the start. It's obviously the other doctor Jack Owen (JO). Adam James always plays malevolent characters."
A third fan commented: "A tenner says his friend Jack is setting him up. Adam James always plays slippery types," while another tweeted: "I had 'uncle Jack' picked out in last week's episode."

A number of other viewers also took to Twitter to praise the latest twist-filled episode, with one person writing: "Ooh. #TheSuspect is shaping up nicely on @ITV.

A third commented: "#TheSuspect is shaping up to be a really great drama. Fantastic performances, brilliant direction, and a properly good twist-and-turn fuelled mystery."
For those who have yet to catch up with the new series, it follows Doctor Joe as he becomes involved in the murder case and is only too willing to offer his expertise.
"Now known for his risk-taking and rule-breaking does Joe have more to hide?" teases the ITV synopsis. "His recent diagnosis with a degenerative condition could explain his behaviour. But as the investigation into the woman's death gathers pace, we start to ask, do we know the real Joe, or does he have a secret life? And has his work as a clinical psychologist allowed him to develop a criminal mindset? Or worse?"
