Ekta Kapoor likes throwing a surprise here and there in her serials.

In her popular show, 'Kyunki Saas Bhi Kabhi Bahu Thi', Sudha Chandran will enter as an austere police officer, who is in charge of investigating Trupti's ( who happened to be Tulsi's daughter-in-law) murder.

This is not an easy task, since the entire Virani family is under suspicion. Sudha's entry guarantees more twists and turns in the already complicated plot.
