Camilleri, internationally recognized as the creator of police Inspector Salvo Montalbano, is a multi-dimensional figure in 20th and 21st century Italian literature. This study explores the evolution of his literary identity, the intertextual and cultural influences that shaped his idiosyncratic style, and the cultural, social and geographical significance of his work, both in Italy and internationally. Particular emphasis is placed on the role of the Inspector Montalbano series in the emergence of Sicily as a setting for contemporary detective fiction and as a literary tourism destination. Camilleri's global perspective offers a multicultural narrative rooted in Sicilian everyday life, creating a synthesis of identities that maintains its authenticity while dialoguing with the world; Montalbano himself is presented as a bearer of Sicilian culture and a symbol of moral resistance. Through his language, humor, irony and inner struggle, Camilleri's hero redefines the boundaries of European noir and Italian “giallo”, offering a narrative that is at once popular, philosophical and culturally prophetic.
