Il pino azzurro (1983)

Marco De Vally, a young decayed aristocrat and poet, has been found dead in his room. Suicide or murder ? Police inspector Fabio Russo starts his investigations from a short poem the victim was writing: IL PINO AZZURRO (The blue pine tree), which contains some obscure hints at famous and important people. Other alarming clues are given by Luca Porri, the victim's disquieting and somehow mad psychoanalyst, and Sarah Pierce, Marco's former lover, who put P.I. on the track of a colossal traffic in arms and drug. Eventually, the scandal breaks out: several politicians and financiers are arrested and charged with trafficking in arms and drug and with Marco's murder, which they confess even if the actual killer can't be found. When P.I. Russo hits on Marco's farewell letter announcing his suicide for Sarah's unrequited love, he throws it away.
