All Jock Tamson's Bairns

Dr. Finlay treats a local celebrity of sorts, the Brigadier, a much decorated soldier and highly respected member of the community. He's come down with a high fever and Finlay decides to hospitalize him where he is eventually diagnosed a having typhus. A group of itinerant Irish farm workers also arrives in the area and the locals are not keen with their presence. Mob rule takes over when the Brigadier takes turn for the worse and many in the community blame the workers for bringing disease with them.
