A cop turned writer goes in search of his friend who’s wife was murdered twenty years back to find out if his friend took his revenge or not… which in turn helps him realize his own love that he had held for twenty years.

Hi Olhiveeran. I see a great idea in here but it needs to be simplified. Maybe the Cop/Writer and the friend, who were in love with the wife, go in search of her killer together but the main character starts to suspect that his friend isn't being as honest as he perceived. It isn't the most original idea but it might help get the ball rolling.
