"New York: Confidential!" by Jack Lait and Lee Mortimer is a commentary and guide to the vibrant yet gritty underbelly of New York City written in the mid-20th century. This work serves as an insider's look at the city's nightlife, its notorious characters, and the cultural phenomena that define it, aiming to provide an unorthodox perspective rather than mainstream tourist information. The authors, who have an extensive background in observing and experiencing the city's dynamics, share their anecdotes and insights into places, people, and the often unseen aspects of New York life. The opening of the book provides an engaging introduction, revealing the unique character of Manhattan as a bustling urban paradise with endless entertainment options yet filled with shadows and secrets. It describes a picturesque view of the city, juxtaposed with references to its less glamorous zones, such as "The Canyon," where a mix of down-and-out characters reside. Central to this exploration is the relationship between criminal communities and daily life in the city, illustrated through the character of Frances, the daughter of a bootlegger, whose life becomes entwined with the infamous gangster Dutch Schultz, setting the stage for a narrative steeped in intrigue, hardship, and survival amid New York's chaotic charm.
