In the early 1900s, prior to World War I, New York City was a vortex of vice and corruption. On the Lower East Side, then the most crowded ghetto on earth, Eastern European Jews formed a dense web of crime syndicates. As awareness of this underworld spread across America, so did antisemitism. This is why a coterie of affluent German-Jewish uptowners decided to take matters into their own hands. Worried about the anti-immigration lobby and the uncertain future of all Jewish Americans, the uptowners organized a secret vice squad. This squad, known as the “incorruptibles” took the fight to the heart of crime in the city, waging war on the sin they saw as threatening the future of the community. Dan Slater tells an epic saga of crime and redemption, exhuming a buried history that shaped our modern world. The Incorruptibles was described by the New York Times as “unrivaled” and was chosen as an editor’s pick.
