The Trade With Sparrow

Sparrow questions Babu about the ship but he doesn't budge. Later he calls Chandramukhi and asks her to bring the map to him in exchange for Gopi. Chandramukhi complies but intelligently slips a transmitter in Sparrow's jacket. Later in the chowky she hears him saying the location of the treasure given by the map. That location is none other than Commissioner's place.
