The ITV period detective drama Foyle's War will return for a ninth run as three new two-hour episodes will be filmed in Liverpool between January and April 2014.
Starring Michael Kitchen and inspired by real events in the early Cold War, the new season will feature Foyle (Kitchen) involved in the murky world of espionage in his role as a Senior Intelligence Officer for MI5.
Honeysuckle Weeks will reprise her role as Foyle's trusted aide Samantha Stewart, while thriller writer Anthony Horowitz has once again handled script duties.
The new episodes will also explore the power of American and German industrialists and a major blight of post-war Britain: the Black Market.
"We are delighted to see the return of Foyle's War to ITV," said ITV's Head of Drama Series, Jane Hudson.
"Anthony Horowitz has written three outstanding episodes and the audience are in for a real treat. This series also gives us the chance to take the shoot to one of the jewels of the North West, Liverpool."
The three feature-length episodes are planned to be transmitted in 2015.
