Dear Mukta,
I have just completed reading the entire SS (in one go). It was a captivating read, close to what the serial portrayed but with a timely twist that appears to have prevented Ragini from going down the road to hell further, and both Swara and Sanskaar becoming friends.
So it was Kavita's father who had her killed.
It was a nice touch - having her mother tell the facts to Sanskaar (he would believe her) rather than Swara, (Sanskaar would not have believed her).
A lovely story where Sanskaar's angst, his repentance and his journey towards redemption have been brought out beautifully.
