EASTENDERS killer Nicola Mitchell will make a fatal mistake next week.

Viewers know that Nicola killed her son Harry’s girlfriend Shireen and let him be blamed for it all.

It was revealed earlier this year that the body had been buried on some scrubland in Catford where the family used to live.

However it was also revealed that an unwitting Teddy had bought the land to develop and make lots of filthy money.

Now next week Nicola’s secret is threatening to be revealed.

And she’s about to make a fatal mistake while trying to keep everything quiet.

Teddy attempts to take a clandestine call from Junior about their project, but when Nicola overhears the conversation, Teddy is forced to reveal all.

Despite Nicola’s pleas, Teddy refuses to pull out of the business deal, and later recruits Ross to join the build.

When Nicola arrives to offer Teddy support, she is shocked to hear the location of the site – it’s the same place where Shireen’s body is buried.

Later, Nicola panics as Teddy informs her that construction will begin at the site this week.

In a panic, Nicola summons Benji to Harry’s Barn but it clearly doesn’t go well for her as later she’s forced into making a new plan.

Out of options, Nicola tells Ravi she has a job for him but will he take it?

Later in the week at No.1, Teddy, Harry and Barney pull out all the stops for Nicola’s birthday, but it’s clear she’s  distracted.

And while they’re distracted she slips out and summons Ravi to Walford East and offers him £10k for a job.

Will Ravi take the job? Fans know he’s not opposed to doing dirty work for the right motivation.
