The night before his death, Adolf Hitler gave his bodyguard a work of exceptional value: Pathologia Sexualis, written by his compatriot Kraff-Ebing in 1886. Ariadna Gaspi, a young art historian
and restorer, is involved in the restoration of an Adoration of the Magi who mysteriously disappears while is involved in the heated controversy that began with the work of the artist
commissioned to create a new mural on the Palma Cathedral and the discovery of the body of Paul Fuster, canon of the cathedral, was murdered by a sexual ritual described in the book of
Kraff-Ebing.
