Eduardo Mendoza studied law in the first half of the 1960s and lived in New York between 1973 and 1982, working as interpreter for the United Nations.

He maintained an intense relationship with novelists Juan Benet and Juan García Hortelano, poet Pere Gimferrer and writer (and neighbour) Félix de Azúa.

The third (and last) novel of the saga, La aventura del tocador de señoras (The Adventure of the Powder Room) was published in 2002.
