TRUE CRIME. Beginning in the summer of 1903, an insidious crime wave filled New York City, and then the entire country, with fear. The children of Italian immigrants were kidnapped, and dozens of innocent victims were gunned down. Bombs tore apart tenement buildings. Judges, senators, Rockefellers, and society matrons were threatened with gruesome deaths. The perpetrators seemed both omnipresent and invisible. Their only calling card: the symbol of a black hand. The crimes whipped up the slavering tabloid press and heated ethnic tensions to the boiling point. Standing between the American public and the Black Hand's lawlessness was Joseph Petrosino. Dubbed the "Italian Sherlock Holmes," he was a famously dogged and ingenious detective, and a master of disguise.
