One fan believed Pierce was on the phone, tweeting: “So who was on Rhona’s phone that Graham heard the message and deleted it… Pierce? Who did Graham batter… Pierce? Who kills Graham… Pierce? Just saying!!”
Another commented how the time is ripe for the convicted criminal to return: “My money is on Pierce, somehow, someway”.
One terse sleuth added: “Pierce kills Graham, I reckon…”.
All the current suspects are big names on the show – would the soap really allow one of their major stars to be the murderer?
Emmerdale continues on ITV tonight at 7pm.
