What ever the matter maybe if Mrs.Durrani says she is a family friend of Dr.Rajesh Talwar then they should be helpful to Dr.Talwar as I dont think Dr.Talwar himself has murdered his daughter I dont trust police according to me to solve the case police has solved the case too early and police dont wanna saw their false or there is some big conspiricy played against Dr.Talwar... May be there is some kind of suspense in this case.
