After exhibiting her works in Paris, Antwerp, Vienna, Munich or Berlin in the early 1990s, Bossu died prematurely in a car accident in 1995, aged 33.

Standing in the tradition of Marcel Duchamp, Bossu "used the language of the ready-made to construct machines that become metaphors for alienation, isolation, and death in everyday life.

[4][6] In the early 1990s, Bossu exhibited her works in Paris (MAM; January 1992), Antwerp (M KHA; February 1992), Vienna, Munich or Berlin.

[4][10] In État de fait (1990), six desk lamps are pointed at the viewer while an answering machine plays beeps and bits of innocuous sentences.

[11] The title is inspired by Maurice Blanchot's novel Au moment voulu, where the narrator describes a situation in which he feels the existence of a will that goes beyond him and encompasses him.

[12] In the magazine art press, Claudia Hart described Bossu's works as an existential search for the "raw, naked expression of human pain", breaking with the approach of "her master Marcel Duchamp."
