Thanks to this collaboration, I not only got to narrate the 39Mafia Queens of Mumbai39, but also discover the complex situations, characters and uncertainty that shaped each of these women39s stories.

It is so powerful. I was narrating her story, but also listening to it for the first time and it was fascinating. For me, Sapna39s story was a thriller and romance combined into one, it was shocking, gripping and impressive to know what she went through. I know it39s going to be a favourite among listeners," he said.Rajkummar, who was last seen on-screen in "Stree", says he would love to work with Radhika and Kalki in films too."It has to be a story where we can all do justice to our parts and have good roles.
