On a cold November evening, a body of an undocumented Sri Lankan immigrant is found in a Venice canal. Guido Brunetti is assigned to investigate the murder. But there's no official record of the man's presence in Venice. And he is forced to use the city's far richer sources of information: gossip and memories ... He gathers a team and stumbles over something that transports him back to his own student days. Brunetti's 32. case.
