Death in a Strange Country - Donna Leon

An American from the military base at Vincenza is found floating in the Venice lagoon, and Commissario Guido Brunetti's instincts tell him that it's no accidental death or mugging gone wrong. Calling upon informants ranging from his aristocratic father-in-law to a local petty criminal and his Sicilian mother, Guido finds himself delving into the murky waters of international corporate crime....

Death in a Strange Country has rewhetted my appetite for Donna Leon, if only the Barbican Library can oblige...

Oh - I've just read on the dust jacket that this is the second in the Brunetti series, which explains why some of the more familiar faces are missing, including the excellent Signorina Elettra.
