Examination of the body reveals it not to be an old woman, but one in her twenties; killed about five years earlier. The skeleton is finally identified as Ducci's ex-girlfriend, Agneta Bignardi, who vanished several years ago. Virginia is determined to exculpate her husband, and contacts her friend Luca Fattori (Marc Porel). Fattori is a researcher of psychic phenomena, and his investigation eventually leads to the wealthy Emilio Rospini (Gabriele Ferzetti), who may be the true culprit.
