On a cold Venetian night shortly before Christmas, a street vendor 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. The dead man was one of the many African immigrants purveying goods outside normal shop hours and trading without a work permit. Once Commissario Guido Brunetti begins to investigate this unfamiliar Venetian underworld, he discovers that matters of great value are at stake within the secretive society. And his boss's warning to avoid getting involved only makes Brunetti more determined to unearth the truth behind this mysterious killing.
