Millions of viewers have tuned in to watch the first two episodes of Robson Green’s Tales from Northumberland.
The eight-part ITV series, screened on Mondays at 8pm, follows the Wire in the Blood star as he travels around the county of his birth.
A staggering 3.8million people watched the first episode, which aired on Monday, October 28.
The 48-year-old visited Seahouses and spent a night on the Farne Islands in the series opener.
Viewing figures increased for the second episode, screened three days ago, with 3.9million people tuning in to see Green visit Kielder Observatory, stay overnight in a bothy and meet shepherdess Emma Gray.
Jude Leitch, general manager at Northumberland Tourism, believes it will encourage even more people to visit the county.
She said: “Obviously we are delighted by this. It is fabulous for the county and we are very excited by it.
“Not only is it an entertaining programme, but it shows the diversity of the county.”
The show is also attracting interest in the world of social media, as part of a combined effort between Northumberland County Council, Northumberland Tourism and tourism partners.

During the course of the series, Green discovers a side of Northumberland that he never knew.
He immerses himself in many of the unique experiences the Secret Kingdom has to offer and meets a host of the county’s colourful characters.
This Monday coming, the third episode will follow Green as he visits Bamburgh Castle and Holy Island. He also joins Amble-based GP Dr Ben Burville, from Morpeth, to go seal swimming.
Green said: “Swimming with the seals is an experience that I will never forget.”
