Michelle Keegan will film four different 'Coronation Street' murder storylines.
The actress is bowing out of the ITV soap in May and TV bosses are so determined to keep the identity of her character Tina McIntyre's killer a secret, Michelle is having to film alternate endings to keep fans guessing.
A source told The Sun newspaper: "Bosses are keen for Tina's murder to be the soap's next big dramatic storyline following the suicide of Hayley Cropper.
"But they are insistent that who kills her must remain a secret and so they've hatched a plan to film Tina being murdered four times by four different characters. Michelle will have to go through Tina's death on four occasions, which will be emotional for her."
Those likely to be in the frame as Tina's killer are alcoholic Peter Barlow, with whom the barmaid had an affair, his wife Carla, Rob Donovan, who is Carla's brother, and previously convicted murderer Tracy Barlow, who is Rob's girlfriend.
Following the news of Michelle's departure after seven years in Weatherfield, it was announced that Chris Gascoyne, who plays Peter, is expected to leave at the end of the year, and now it seems Marc Bayliss, who plays Rob, could also be leaving once the dramatic plot comes to an end.

Simon Cowell is creating a game show for children.
The 'X Factor' and 'Britain's Got Talent' creator - who is expecting his first child with girlfriend Lauren Silverman this month - is hoping to entertain youngsters with 'Keep It In the Family'.
The game show allows children to call the shots over the adults in their lives.
The Saturday night primetime show is set to be hosted by Bradley Walsh and will see the kids win prizes for their families by completing a series of challenges.
Simon's family-friendly game show format follows his high profile flop 'Red or Black?', which was hosted by Ant and Dec.
The expensive show - which had two series between 2011 and 2012 - boasted a £15 million budget and a £1 million grand prize for the winner.
However, ratings and reviews for the series were unimpressive.
Meanwhile, it is believed Simon, 54, could return to the panel of his first hit show 'The X Factor' this year after quitting for the US version in 2011.
A source said: "Cowell is determined to get the show back to its best.
"He'll sign the deal very soon but has told the team that he's on board. Everyone's over the moon."

Vicky Pattison insists she's not a "vile monster" after being convicted of assault.
The 'Geordie Shore' star - who was sentenced on Monday (03.02.14) for attacking a young model with her stiletto shoes in a nightclub last July - is deeply remorseful over her actions and claims the incident, which resulted in 18-year-old model Hannah Kelso requiring four stitches, was a "mistake".
Vicky lamented to the Daily Star newspaper: "I'm so sorry. I'm not a vile monster. I'm just a normal girl who made an awful mistake."
The 26-year-old MTV star flung her stiletto in Hannah's direction, wrongly believing the teenager had thrown ice at her during a night out in Newcastle's Florita's Bar. The shoe hit both Hannah and security guard Victoria Burns, whose lip was cut in the fray.
Vicky said: "If I could go back to that night I wouldn't recognise the person who did those things. It wasn't me. I would implore them to understand that I am human just like they are. I have so much regret. I made a mistake."
The brunette beauty blames her wild behaviour on her failed engagement to fellow 'Geordie Shore' star Ricci Guarnaccio, 25.
She added: "My relationship with Ricci was draining and I wasn't in a good place. I was so frustrated, angry and utterly exhausted."
Vicky was ordered to complete 180 hours of unpaid work and pay both her victims compensation in court on Monday.
MTV hasn't made a decision on whether Vicky will return for the new series of 'Geordie Shore' following the incident.

Steven Moffat has claimed fans may have to wait "four or five years" for more 'Sherlock'.
The TV scribe, who writes the show with Mark Gatiss, teased avid viewers of the hit BBC One crime drama, suggesting they could be in for a long wait to discover how villain Moriarty - played by Andrew Scott - is still alive.
The criminal mastermind, who was believed to have killed himself at the end of series two, reappeared following the credits of last month's third series finale.
Steven said: "That was in the cutting room ... Mark just decided we would use a little bit of it. It was just a final little treat really just to wind people up.
"I was as surprised as anyone when he turned up. He was definitely dead. You can't fake shooting yourself in the face. The back of his head came off.
"I don't know what is going on. I can't wait for four or five years until we make the next episode."
Meanwhile, 'Sherlock' stars Benedict Cumberbatch and Martin Freeman revealed that a gay club scene was cut from Watson's stag party in the latest series.
Martin told fans during a panel at the Apple Store in London's Regent Street: "There was the gay club scene. Why didn't that get in? We got mullered in a gay club and all these topless guys were going by."
Benedict added: "[Sherlock] had no idea why we were there and what it was, and they were all walking past and then I realised."

Kylie Jenner was rushed to hospital after a trampolining accident.
The 'Keeping Up With the Kardashians' star sought medical help yesterday (04.02.14) after a bouncing competition with her half-sister Khloé Kardashian got a little too out of hand.
It is not known what injuries the 16-year-old beauty sustained during the play fighting sequence, but she was not seriously hurt as she took to her Instagram page to share details of the accident.
She posted a picture of herself clutching her nose, which was accompanied with the caption: "In the hospital thanks to @khloekardashian. (Look at her page for the reason why).
"My mom said "never thought I would take u to the doctor for a trampoline accident at this age) this means war Khloe (sic)."
However, Khloé, 29, hit back at her younger sibling, claiming she injured herself by falling over.
She posted a series of four pictures on her Instagram account, which saw the pair bouncing on the trampoline together, before Kylie tumbled and Khloe is seen holding her back.
She wrote: "Kylie this is proof you did it to yourself! Sorry not sorry! Just kidding I am sorry my little bug a boo!! Let the war continue!!!! (sic)."

Perrie Edwards doesn't think she's too young to get married.
The 20-year-old Little Mix singer is engaged to One Direction hunk Zayn Malik, 21, and she says they "know" they are ready to settle down and commit themselves to one another.
Perrie told 'Access Hollywood': "We're young, but I think when you know, you know.
"We've been together for a while now, so it is nice."
Perrie - who got engaged to Zayn last August after almost two years of dating - says she and the 'Little Things' hitmaker get nothing but support from their respective fans.
She added: "The fans have been amazing, they are so supportive of us."
While the couple haven't yet set a wedding date, Zayn's mother, Trisha Malik, recently said she expects them to tie the knot later this year.
Speaking in December she said: ''Perrie is a lovely girl and I get on really well with her.
"They're thinking of the end of next year, although no date has yet been set yet.
"If they have children I wouldn't like to be so far away from them. I would really like to still be part of their lives."

Bill Murray loved seeing Matt Damon "victimised" by George Clooney.
The 'Monuments Men' actor-and-director pranked his co-star by secretly having the wardrobe department take in his clothes every week and Bill admits the entire set were in on the joke.
He said: "The only one who got victimised was Matt Damon. He got Damon pretty good with his uniform. Taking his pants in a quarter-in every week...
"The rest of us just got to enjoy that because we all knew and we'd see him in just firing those abs, really firing them to try and keep those trousers up.
"You'd go 'That's great, do you want to do another set?' and you could see him go like, 'Oh my muscles are fatigued, I'm good', that was good."
Despite falling victim to the prank, Matt insists he had a great time working on the film - which follows an Allied group who try and save pieces of art and other items of cultural importance before their destruction by Adolf Hitler - because everyone was so professional.
He told 'Entertainment Tonight': "It's not that we were like yucking it up or toasting marshmallows on the set or anything, it was really because we've all made a lot of movies and everybody independently appreciated being on a movie where the script was so good, the director knew what he was doing and was in control and where we had fellow cast members who were experienced enough to know that's as good as it gets and it was a best experience for all of us in that way."
And another star of the film, John Goodman says it was one of the best movie-making experiences he has ever had.
He said: "It was probably the most fun I've ever had working on a film. There was a lot of good down time. Swapping lives, telling stories. George was so professional, he had his work done ahead of time."

Matthew McConaughey will star in 'Sea Of Trees'.
The 44-year-old actor has been cast as a suicidal American who becomes friends with a Japanese man, played by Ken Watanabe, who is lost near Mount Fuji, which is the highest mountain in Japan located on Honshu Island, according Variety.com.
Gus Van Sant will direct while Chris Sparling is penning the script and Life Of Pi's Gil Netter is producing.
McConaughey, who has been nominated for an Oscar for his portrayal of a real-life AIDS victim in 'Dallas Buyers Club', previously revealed he's made a conscious decision not to take a part in another romantic comedy, after appearing in 'How To Lose a Guy In 10 Days' and 'Failure to Launch'.
He said: "I'm not going to carry on doing the same thing over and over. I was reading romantic comedies. And I liked them. But I wanted to do something that scares me a little bit.
"The first move was saying 'no' to scripts. That was six months of 'no' and then a year of nothing. And something happened. I gained anonymity and suddenly it became a good idea for William Friedkin [director] to call about 'Killer Joe' or Steven Soderbergh about 'Magic Mike'."
McConaughey who currently stars in 'Dallas Buyers Club' and 'The Wolf Of Wall Street' will next be in Christopher Nolan's sci-fi film 'Interstellar'.

Clean Bandit want Craig David to come out of retirement for a collaboration.
The 'Rather Be' hitmakers are enjoying their second week at the top of the UK Official Singles Chart and have admitted they'd love to work with the 'Re-Rewind' singer whose last album 'Signed Sealed Delivered' was released nearly four years ago.
Lead singer Grace Chatto said: "Craig David is the singer we'd love to work with most. It's controversial, maybe, but he's got a great voice. We're big into that old UK garage sound and Craig was the best."
Although they haven't managed to coax him out of retirement in time for their debut album 'New Eyes' - which is set to be released on May 12 - they have been working with another garage legend, 'Greater Love' singer Elizabeth Troy.
Grace told the Daily Star newspaper: "Elizabeth is now with us all the time and we just made a track called 'Heart On Fire' with her that's a garage tribute."
The electronic quartet - which also features Jack Patterson, Luke Patterson and Milan Neil Amin-Smith - have also collaborated with other artists who help the album feature a mixture of different genres.
Grace added: "There's a song we've written with a US rapper called Lizzo ... one with Stylo G that's got a dance hall element to it.
"It's a big hotchpotch of different styles but a constant sound runs right through it."

Taylor Swift was joined on stage by The Script's Danny O'Donoghue at London's O2 Arena last night (04.02.14).
The 23-year-old singer surprised fans at her third 'Red' tour gig in the city by bringing out the former 'The Voice' mentor as her surprise guest.
Taylor told the crowd: "One of my favourite things about coming to the UK is that I've discovered bands that have become some of my favourites. There's a band I first heard when I came over here ... They have a really great lead singer - it's Danny O'Donaghue from The Script!"
The pair performed a duet of the Irish band's hit song 'Breakeven' to rapturous applause, with Taylor thanking the crowd for being the "craziest yet".
The country starlet - who was supported by new boy band The Vamps - kicked off the show with her 'Red' album opener, 'State of Grace', before launching into popular title track 'Red'.
Amid costume changes and gravity-defying stage antics, Taylor powered through her best songs from her latest album, including 'I Knew You Were Trouble' and grand finale 'We Are Never Ever Getting Back Together', as well as a handful of old favourites like 'Mean' and 'Love Story'.
The singer also explained her fascination with the colour red, which featured prominently in the elaborate theatre-themed staging and her various sparkly get-ups.
She said: "I bet a lot of you are wondering why there's a fixation on this one colour. When I was writing my last album I came up with the idea of comparing feelings to colours and there was this one that represents all the emotions; love, hate, jealousy, passion ... If you had to pick one colour that's intense, fleeting, beautiful and sad all at once when we fall in and out of love it would be red."
Taylor's 'Red' tour continues on Monday, February 10 and Tuesday, February 11.
To coincide with her residency at The O2 Arena, the British Music Experience - which is situated inside the O2 - are showcasing select items from Taylor's wardrobe alongside photographs by Christie Goodwin in a pop-up exhibition.
Admission to 'Taylor Swift: A Photo Experience' is included within the price of a museum ticket, and costs just £4 to ticket holders for her O2 shows during the duration of her residency.
The exhibition runs until 23 March.
