You could have a great career, And you should; Yes you should. Essie Davis’ voice is as fabulous as Miss Fisher. After spending the day at the radio station solving a murder, Phryne and Jack return to her home to misbehave! Only one thing stops you dear: You're too good; Let's Misbehave Lyrics: We're all alone / No chaperon / Can get our number / The world's in slumber / Let's misbehave! / There's something wild / About you, child / That's so contagious / Let's be Lyrics to 'Let's Misbehave' by Elvis Costello.
