True Detective

In the mob-choked Chicago of 1932, private detective Nathan Heller may be willing to risk his life to earn a Depression dollar, but he never sacrifices his sardonic wit.
When Mayor Cermak's 'Hoodlum Squad' brings Heller along
on a raid with no instructions but to keep his mouth shut and his gun handy, he becomes an unwitting, unwilling part of a hit on Al Capone's successor, Frank Nitti. As a result, Heller quits the force to become a private eye; his first job head off a nation-shaking political assassination in Miami Beach. With the Chicago World's Fair as a backdrop, Heller encounters a Ragtime array of
crooks and clients, including Al Capone, George Raft, 'Dutch' Reagan, and FDR himself.
Rich in riveting plot turns, including a heartbreaking romance, True Detective is one of the most highly entertaining and unlikely coming-of-age stories written.
