WARNING: POTENTIAL SPOILERS AHEAD
EastEnders bosses promised that Shabnam Masood (Rakhee Thakrar) would be harbouring a deep dark secret when she returned to Walford last year.
And, next week, we will see her life slowly begin to unravel as new clues emerge…
Viewers will watch as Shabnam offers to help new friend Stacey Branning (Lacey Turner) by lending her £100 in cash in a bid to help her and Kat Moon (Jessie Wallace) get their lives back on track.
Which isn't too surprising - especially since she gave Tamwar a whopping £10K in cash for his 21st.
The Minute Mart employee then joins Stacey and newcomer Kush (Davood Ghadami) for a drink at The Vic and winds up leaving her handbag there - prompting smitten Kush to return it to her.
But, when he makes a joke about it, Shabnam furiously demands that he and Stacey leave her alone.
Finally alone at home, she is then seen rifling through her bag and sighing with relief as she discovers a hidden newspaper cutting.
Her secret is still safe - but what on earth could it be?
Some have suggested it could be to do with Lucy Beale's murder - especially as Shabnam isn't the only one on Albert Square to have her own stash of creepy newspaper cuttings.
But we're not all that convinced; after all, murdering Lucy wouldn't make Shabnam rich or any happier…
…or would it?
One thing's for sure, the revelation will certainly be shocking.
EastEnders star Rakhee Thakrar has revealed that viewers will be left gobsmacked when her character's secret is finally revealed.
The actress told Inside Soap: "Shabnam's secret is life and death."
"Since she came back home, Shabnam has become really good at hiding things, because she knows that everything would come apart if it ever got out.
"I've been carrying this secret around for the past year, and it's really weighing heavily on me!"
She continued: "I can never gauge how the audience are going to react to things. But lots of people who work on EastEnders were shocked when they discovered Shabnam's secret, so I hope it has the same effect on the viewers.
"I'm really excited and nervous about it coming out."
We can't wait to find out more about Shabnam's deep dark secret - what do you think it could be?
