Loner in the rush hour crowd

This book is a psychological detective story. The hero eliminates evil in a classical way: by eliminating its carriers. The objects of his work are modern «masters of life» (nouveau riche, multimillionaires from yesterday’s ignoramuses, criminals and speculators) and and their henchmen. They are an obstacle on the way of a person to worthy life, and therefore the hero resorts to extreme methods of «re-education». Maybe this is the only sure way to establish the «kingdom of God» on Earth?!
