In broad daylight, well-known deputies of the State Duma, co-chairs of the Progressive Russia party, were killed. Although the official investigation does not admit it, it has reached a dead end. The comrades-in-arms of the dead politicians, concerned about their own safety, decide to hire a private detective Denis Gryaznov, so that with the help of his agency he will protect them and expose the customer. And anyone can be a customer: the recently created Progressive Russia has already gained some popularity and has been like a bone in the throat of various political parties and groups.
