Jan Madsen is a fictional character featured in Luther: The Calling.
Jan is the wife of Jeremy Madsen. She was a pharmacist, but she later retired. She and Jeremy adopted a son together, Henry. Unfortunately, he was a psychopath and caused the couple nothing but trouble.
Jan appears in Luther: The Calling, in which she and her husband are held hostage by their adopted son, Henry. He has just kidnapped Mia Dalton and buried her with a limited amount of oxygen, and he calls Jeremy and Jan to inform them that if they don't give him money, the girl will die. DCI John Luther and DS Isobel Howie arrive at their house to question them, but Luther deduces that Henry is holding them hostage. While Luther heads upstairs, Henry attacks Howie and Jan in the kitchen, killing Jan by thrusting a screwdriver through her eye socket, and gravely wounding Howie.
