Set in swinging '60s Melbourne, the gorgeously reckless Peregrine Fisher inherits a windfall when the famous aunt she never knew, Phryne Fisher, goes missing over the highlands of New Guinea.
Detective James Steed is a smart, ambitious cop constantly hamstrung by the rigid leadership of his immoral boss but respectful of the hierarchy. Instantly attracted to Peregrine, he's dazzled by her audacity and often drawn into her mad plans.
With a mind like a steel trap, and ex-member of WW2 Special Forces, Birdie is the 'M' of The Adventuresses' operation and club president. A tough woman of high expectations, she recognises the '60s are changing and they need new blood - but having Peregrine under her wing is also a way of staying connected to the old friend she misses desperately.
