On a cold Venetian night shortly before Christmas, a man is killed in a scuffle in Campo San Stefano. The closest witnesses to the event are the tourists who had been browsing the man's wares before his death - fake handbags of every designer label. Officially termed avenditore ambulante or extracomunitario, the dead man was working as a vu cumpra, one of the many Black Africans purveying goods outside normal shop hours and without work permits. Arriving on the scene, Commissario Brunetti's response matches that of everybody involved: why would anyone kill a vu cumpra? With few social connections and little money, in -fighting amongst these workers is the obvious answer. But once Brunetti begins investigating this Venetian underworld, he discovers that matters of great value are at stake within the immigrant society.
