Notorious Eastenders character Cindy Beale is returning to Albert Square � as a �ghost�.

The character, played by Michelle Collins, will re-enter the soap as her ex-husband Ian Beale and daughter Lucy begin receiving mysterious emails and texts from her � despite the fact she supposedly died whilst giving birth in prison nine years ago.

The Sun reports,�It starts when Lucy gets emails from her mum but then things get sinister. Ian finds a message reading �I�m back� scrawled on the mirror and the room smells of Cindy�s perfume.

"Then he is sent a picture of her � looking older than when she supposedly died. Eventually he receives a message asking him to meet her � at her grave."

Collins herself gave a clue as to how she could be written back into the series last year when she said,� There's talk of Cindy�s death being staged and her being in a witness protection programme. I wouldn�t say no to returning."
