The perpetrators’ only calling card was the symbol of a black hand. Standing between the American public and the Society of the Black Hand was Joseph Petrosino. Dubbed “the Italian Sherlock Holmes,” Petrosino was an ingenious detective and master of disguise. As the crimes grew ever more bizarre, Petrosino and his all-Italian police squad raced to capture members of the secret society before the nation’s anti-immigrant tremors exploded into catastrophe.
The Black Hand is a “taut, brisk, and very cinematic” true crime history of America at the dawn of the 20th century (Newsday).
