“Bill Reardon (Melvyn Douglas) is a struggling private detective. His wife Sally (Joan Blondell) had push him into quitting a well paying investigating job in the DA office. He goes off to get his old job back. Famous socialite Lola Fraser comes in looking to hire an investigator and Sally promptly takes the job pretending to be an investigator. She starts investigating behind her husbandu0026#39;s back which gets complicated when the DA office gets involved in a murder case.u003cbr/u003eu003cbr/u003eThe one and only issue I have is Billu0026#39;s constant physical fake-outs against his wife. He keeps pretending to hit her and missing by the barest margin. He even throws something at her. Itu0026#39;s another era and itu0026#39;s supposed to be funny. Itu0026#39;s like Ralph Kramden. It hasnu0026#39;t aged well. Otherwise, the combative rapid-fire banter is fun.”
