When the nymphomaniac Maria Zani (Barbara Bouchet) is murdered, her ex- husband and insurance broker Paolo Zani (Silvano Tranquilli) becomes the prime-suspect of Inspector Tellini (Giancarlo Giannini). Then the saleswoman Mirta Ricci (Annabella Incontrera) is murdered in the same modus operandi – both victims had been paralyzed by acupuncture needles with poison introduced in their necks and their bellies had been ripped open with a knife with the victims still alive, in the same way that tarantulas are killed by tarantula hawks. The police find that she was also a drug dealer,
Paolo meets Inspector Tellini to tell him that he is innocent. Further, he hires the private eyes La Catapulta that finds the last man that had met Maria, the photographer Mario (Giancarlo Prete). Paolo pursues Mario but they both die and Inspector Tellini finds an envelope addressed to Franca Valentino with Mario. Inspector Tellini discovers that he was a blackmailer and meanwhile Franca becomes the third victim of the serial killer. When the masseuse Jenny (Barbara Bach) is found dead wrapped in plastic bag, Inspector Tellini goes to the massage parlor to meet the manager Laura (Claudine Auger) and he believes that an employee may be the serial-killer.
"La Tarantola dal Ventre Nero" is a great "giallo" with the typical structure – a serial-killer that wears gloves and the identity is only discovered in the end; the victims are beautiful semi-naked women; gore deaths; a persistent detective pursues the killer; and wonderful music score.
The story is well developed, with many plot points. The very young Giancarlo Giannini works with very beautiful women, three of them future Bond girls (Claudine Auger and the Barbaras Bouchet and Bach). The great music score of Ennio Morricone completes the work of the director Paolo Cavara. My vote is seven.
Title (Brazil): "O Ventre Negro da Tarântula" ("The Black Belly of the Tarantula")
