What is the alter ego of the superhero comic book character Linda Carter?

"Night Nurse" is a Marvel Comics comic book series published in the early 1970s, as well as the alter ego later taken on by one of its characters, Linda Carter. Carter was one of three central characters who first appeared in "Night Nurse" #1 (cover-dated Nov. 1972), though she was previously the lead of another Marvel series, "Linda Carter, Student Nurse", published in 1961. Carter later adopted the name "Night Nurse" for herself, and in this incarnation, first appeared in "Daredevil" #58 (May 2004), as a medical professional specializing in helping injured superheroes.

Linda Carter is the daughter of a doctor in Allentown, New York. After moving to New York City and moving in with roommates Christine Palmer and Georgia Jenkins, she meets and falls in love with Marshall Michaels, a wealthy businessman. When he forces her to choose between marrying him or staying at Metro General as a nurse, she chooses her career. In the following two issues of the series, Linda demonstrates that her skills are not limited to nursing practice, as she performs detective work to help expose an incompetent surgeon and prevents a hitman from murdering a patient. By the time the series was canceled, she had started a budding romance with Dr. Jack Tryon, a young resident doctor. Palmer is the protagonist of "Night Nurse" #4, with Carter making a one-panel cameo and Jenkins not appearing at all.
