Ellery Queen (1975)

S1E18 The Adventure of the Two-Faced Woman

Simon Brimmer once more misidentifies the true perpetrator in this story surrounding the murder of a socialite who seemed to have been living a secret life. The investigation is rooted in occurrences from France in 1922. The path to uncovering the truth is challenging, but as always, Ellery follows the right trail to solve the mystery.
