Essie Davis (The Babadook, The Slap) returns as Miss Phryne Fisher, a "lady detective" from Melbourne with a fabulous sense of fun and a flair for solving crimes. In a country reemerging from the shadow of World War I, Phryne takes life in her stride-and murder, too. Detective Inspector Jack Robinson (Nathan Page, The Secret Life of Us) works alongside her, although she often outraces him to the crime scene. Despite Jack's efforts to keep matters on a professional level, their playful partnership is growing more and more personal. In Series 3, Phryne and Jack's developing relationship is matched by the on-again, off-again romance of Phryne's assistant,"Dot" Williams (Ashleigh Cummings, Tomorrow, When the War Began), and Jack's constable, Hugh Collins (Hugo Johnstone-Burt, San Andreas). But with the unexpected arrival of her father in Australia, Phryne recalls troubling incidents from her past-and contends with ominous affairs in the present.
