Sandra Knight is the daughter of US
Senator Henry Knight. In her origin story
at Quality, while she is waiting for her
father on the steps of the US Capitol
building, two kidnappers attack her
father. Sandra fends them off with a
newspaper (really!), and disappears
into the shadows before her father
realized who saved him. The story is
similar at DC, but she uses her fists
instead of a newspaper. Anyway,
Sandra liked her brief outing as a
mystery-woman, and one day she
discovers a black light ray emitter
developed by a man named Professor
Davis. The blackout ray projects
darkness, and when she turns the ray
on herself, Sandra becomes invisible.
Calling herself Phantom Lady, she
fights crime wearing a revealing yellow
bathing suit, a green cape, and green
goggles.

Phantom Lady's golden age adventures last from Police Comics #1-23 and also include three adventures in
Feature Comics (issues #69-71). Phantom Lady was one of the founding members of the second Freedom
Fighters team, and she is also the cousin of Starman Ted Knight. As revealed in the series Damage, in the
1960's Phantom Lady is recruited for the spy agency Argent, a branch of the O.S.S. Phantom Lady is
teamed with Iron Munro, and the two partake in several missions to stop the schemes of Baron Blitzkrieg,
who is now working for the Soviets. Phantom Lady and Munro become lovers and eventually have a child
that is kidnapped by Blitzkrieg. Her marriage to Munro doesn't last, and she leaves him. Munro is left to
believe that Sandra was killed in action.

Currently, Phantom Lady is a teacher and headmistress at the University Notre Dame des ombres (Our
Lady of the Shadows), a spy training school. Dee Tyler, one of Knight's students at the university, debuted
as Phantom Lady II in Action Comics #636 in 1988.
