can someone explain the part where wazir Ali kills the British lawyer ...
I understood that he was removed from his power and authority and send to banaras . he was called by the British General. he then went to the company's lawyer who was in banaras and complained to him .. What happened after that I need an explanation 

Hi.. here is the explanation.. hope that you understand.. wazir ali was given a post in banaras but within few months , the governor transferred him to kolkata. This angered wazir ali. So he consulted the lawyer to provide with a justification why he was transferred within a few months. Instead of helping wazir, the lawyer started shouting and back answering him.. this angered wazir and he killed the lawyer at his home.. thumbs up; please..
