Anil was in the corridor when he was telling the cops that He never expected that Sarika will not take that property papers as she is one greedy person, Now only Vikram knows that she lies under her nose when she coughs so that could be way to get her to confess or If Vikram hears something when they Vikram & Naani are heading to Shobha's place has heard anything.
Also Satika's nite mare will prick her she has to do something wrong and get trapped.
I wish Vikram is the one to teach her a lesson OR her own conscious will bring that out in the open.
