Description

In the centre of the night time in the Memorial of Volterra, small archeologist Fabrizio Castellani is submerged in his work - study in to the well-known Etruscan sculpture referred to as 'the shade of twilight'. Totally immersed, he's shocked by the telephone ringing. A frozen feminine speech cautions him to reject his work on once. A number of grisly murders briefly follow, tossing the folks of Volterra right into a stress.
