Overall, an excellent expedition into a little-remembered past. La Mano Nera was the genesis of the American mafia, and in this account there are no "white hands" as in Mario Puzo's reconstructions. A terrorist organization whose only goal was profit and power, it preyed on vulnerable Italian immigrants in "colonies" across the US at a time when immigrants were de facto segregated in a strange land.
Joseph Petrosino was one of the "good" ones who refused to bow to terrorism or stereotypes. Author Stephen Talty rebuilds his life and career as a no-nonsense counter-terrorism agent. His greatest asset was his Italian Squad's embedded position in New York's Little Italy. Yet with limited resources, granted only for publicity reasons by superiors, he was dabbling the surf with a spoon. By exploiting his success to track down Black Hand to its source, he was set up for murder in Sicily.
Petrosino's legacy survived in Little Italy, with long out-of-print biographies in his wake and a "correct" film portrayal by Ernest Borgnine that, for all its shortcomings, was based on the historic record and gave a feel for the time and place. The Black Hand is largely forgotten, yet at the time had been transformed into the era's major anti-terrorist crusade, with all Italians guilty by default as would be all Muslims a century later. The public backlash led Italian communities to draw a veil over a past that did them no credit, even going so far as to deny the organization ever existed, even when victimized by it. This spirit of denial persists today - especially from those with a vested interested in doing so.
A worthwhile light shone into a dark alley of New York life, like peeking into a preserved period house and finding the past is not as it is remembered; but is indeed another country, strange yet strangely familiar.
