Lady S is a Franco-Belgian comics series written by Jean Van Hamme, illustrated by Philippe Aymond and published by Dupuis in French and Cinebook in English.

Adopted daughter and principal collaborator of James Fitzroy, roving ambassador, special correspondent for the American Secretary of State in Europe, Susan is a clever, multilingual young woman, in full bloom and perfectly happy in the eyes of an attentive father.

Trapped by her past, Susan will have to play her most dangerous role in a life already rich with adventure: Lady S, high-class spy in a diplomatic environment.

Suzan, still her adopted father's assistant, is now working at the White House, where she becomes the unwilling central figure in a nefarious plot to discredit the president of the United States.

The whole mission spirals out of control when she rushes to Portugal, after the CIA contacts her to tell her they've found a man who calls himself Abel Rivkas... her father!.
