9 May
Summary
- Mark Harmon and retired NCIS agent Leon Carroll Jr. co-authored 'Ghosts of Sicily'.
- Their new book details an NCIS investigation into the Sicilian Mafia's influence.
- Harmon and Carroll have a decades-long friendship built on their NCIS connection.
Mark Harmon, renowned for his role as Leroy Jethro Gibbs on "NCIS," has partnered with retired NCIS Special Agent Leon Carroll Jr. to co-author a new book, "Ghosts of Sicily." This latest work investigates a genuine NCIS case focused on the Mafia's pervasive control over the island. Their collaborative writing venture is a natural extension of a deep, decades-long friendship that began on the "NCIS" set.
Carroll, who spent 21 seasons as the show's technical advisor, brought invaluable real-world experience to the series. The duo previously released "Ghosts of Honolulu" in 2023, detailing a Japanese spy and a Navy counterintelligence agent's efforts before the attack on Pearl Harbor. They followed this with "Ghost of Panama," which explored a case in Central America.
"Ghosts of Sicily" chronicles the Office of Naval Intelligence's controversial alliance with the mob in 1942 New York to protect waterfronts. The book highlights the ONI's dealings with figures like Charles 'Lucky' Luciano and the vital role this operation played in the war effort and the growth of international crime.
Harmon, who departed "NCIS" in 2021 after 18 seasons, expressed his deep respect for Carroll and the demanding nature of his work. He views their continued collaboration on books as an extension of his portrayal of an NCIS agent, bringing authenticity to their shared passion for uncovering historical events.
