The Gangster by Clive Cussler
I am currently reading the fast paced exciting crime thriller The Gangster by Clive Cussler. It is the ninth book to to feature Detective Isaac Bell of the Van Dorn Detective Agency. It starts In 1906, in New York City, where an infamous Italian crime group known as the Black Hand led by Antonio Branco, is on a massive crime spree: kidnapping, extortion, arson and generally reeking havoc, threatening Italian businessmen, blowing up the water aqueducts, cuasing industrial accidents and kidnapping the Daughters of wealthy business men.
One of the businesses hires Detective Isaac Bell of the Van Dorn Agency. So Detective Isaac Bell decides to form a special “White Hand Squad,” He finds that he tecognizes an Italian grocer, who now holds the contract to provide food to the Italian workers on the Catskill Aqueduct, as someone he once met years ago. However soon the gangsters appear to be everywhere—so much so that Bell begins to wonder if there are imitators, criminals using the name for the terror effect. And then the murders begin, each one of a man more powerful than the last, and as Bell discovers, to his dismay, the ultimate target may be the most powerful man of all Theodore Roosevelt The President of the United States.
