To combat behavior they viewed as sexually promiscuous, politically undesirable, or downright criminal, social activists in Progressive-era New York employed private investigators to uncover the roots of society’s problems. New York Undercover follows these investigators—often journalists or social workers with no training in surveillance—on their information-gathering visits to gambling parlors, brothels, and meetings of criminal gangs and radical political organizations.

Drawing on the hundreds of detailed reports that resulted from these missions, Jennifer Fronc reconstructs the process by which organizations like the National Civic Federation and the Committee of Fourteen generated the knowledge they needed to change urban conditions. This information, Fronc demonstrates, eventually empowered government regulators in the Progressive era and beyond, strengthening a federal state that grew increasingly repressive in the interest of pursuing a national security agenda. Revealing the central role of undercover investigation in both social change and the constitution of political authority, New York Undercover narrates previously untold chapters in the history of vice and the emergence of the modern surveillance state.

Notorious New Jersey is the definitive guide to murder, mayhem, the mob, and corruption in the Garden State. With tabloid punch, Jon Blackwell tells riveting accounts of Alexander Hamilton falling mortally wounded on the dueling grounds of Weehawken; Dutch Schultz getting pumped full of lead in the men’s room of the Palace Chop House in Newark; and a gang of Islamic terrorists in Jersey City mixing the witch’s brew of explosives that became the first bomb to rock the World Trade Center. Along with these dramatic stories are tales of lesser-known oddities, such as the nineteenth-century murderer whose skin was turned into leather souvenirs, and the state senator from Jersey City who faked his death in a scuba accident in the 1970s in an effort to avoid prison.

Blackwell also sheds light on some historical whodunits—was Bruno Hauptmann really guilty of kidnapping the Lindbergh baby? Who was behind the anthrax attacks of 2001? Not forgotten either are notorious characters who may actually be innocent, including Rubin “Hurricane” Carter, and those who have never been convicted of wrongdoing although they left office in scandal, including Robert Torricelli and James McGreevey.

Through 100 historic true-crime tales that span over 300 years of history, Blackwell shows readers a side of New Jersey that would make even the Sopranos shudder.
