Fledgling detective Phryne Fisher is known for her sharp wit and pearl-handled pistol, which she uses to fight injustice in Melbourne during the 1920s. The glamorous sleuth makes her way through the city's alleyways and jazz clubs while she fights crime as part of a larger mission -- making sure that Murdoch Foyle, who she believes is responsible for the disappearance of her younger sister, stays behind bars. She fights for justice for people who can't help themselves, including exploited workers and missing girls.
