Fred Thursday is a veteran Detective Inspector and World War II veteran portrayed by Roger Allam. Thursday served in the North African and Italian Campaigns during the war as a soldier in the British Expeditionary Force after becoming a policeman in London in December 1938. Thursday married his wife, Win, in November 1941, with whom he has two children in their early twenties: Joan and Sam. Thursday is one of the more noble and honourable figures in the series and takes the young Endeavour under his wing, clearly seeing Endeavour's high level of intelligence when it comes to police work. Thursday also keeps Endeavour in line and tries to protect him. Thursday is also highly protective of his family and always avoids corruption and does his best to do what is right and decent. Thursday never talks about his work at home with his family, preferring to "leave work...on the hall stand by the front door".
