A second person tweeted: "NO NO NO... You rascals... I knew #Marcella would be left on a knife's edge... but??? GAGGING FOR MORE!!! @annafriel and all involved... please tell me this is not "the end?!" Surely not?! Cheers to all of you!"
A third echoed this feeling, writing: "OMG! Was that a cliffhanger with the phone ringing and #Marcella leaving it behind or was it a way of leaving Marcella behind completely? I can't believe they all died even Rav, I'm assuming Katherine is still alive overall absolutely phenomenal series."
The final episode in the third series saw Marcella driving away from a scene of many suspected fatalities involving the infamous crime family, the Maguires, and her old police colleague DI Rav. However, Rav's death was not confirmed, and many are hoping a series four will reveal the truth.

Despite fans eager for a fourth series, ITV are yet to confirm whether more episodes of Marcella are going ahead. Leading lady Anna Friel recently teased the potential for a fourth series of the drama to HELLO! and other press in a Q&A.
The actress said: "It was always intended to be a trilogy, but the end of the third season is left very much open. I guess it depends on how much the viewers here like it."
The 44-year-old added: "It's been really well reviewed and respected in all the other counties that have been able to see it, I'm so sorry [the UK] had to wait so long. I think it [also] depends on everyone's availability. But it was intended to be a trilogy, there is a kind of satisfying end to series three as you'll see."
