Coronation Street fans think they have spotted an obvious flaw in Stephen Reid's plan to drug - and potentially kill - his fiancee Elaine Metcalfe as they also believe they have 'worked out' the serial killer's downfall.
His family, colleagues and those living alongside him in Weatherfield are completely unaware that the bogus businessman has already shockingly claimed the lives of three people as he tries to get his hands on Underworld.
Earlier this year, viewers of the ITV soap were horrified when he started drugging factory boss Carla Connor with LSD, making her think her psychosis had returned. Concerned for her mental health, she has now decided to sell her shares in the factory and Stephen has been left miffed that she's not planning to sell to him.
