Paul Newman returns as private detective Lew Harper is this tale of blackmail and murder based on a novel by Ross MacDonald. Iris Devereaux (
Joanne Woodward), the wife of a wealthy oilman from Louisiana, hires Harper after she receives a threatening letter. A blackmailer is threatening to tell Iris' husband James (
Richard Derr) about a recent extramarital affair; she claims this indiscretion never happened, though she has been unfaithful in the past, and years ago had a brief fling with Harper. Matters become more complicated when Iris' mother-in-law Olivia (
Coral Browne) is found murdered. Eventually, Harper traces the blackmail letter to Kilborne (
Murray Hamilton), another bayou oil baron, and along the way encounters Schuyler (
Melanie Griffith), Iris' young but ripe daughter; Pat Reavis (Andy Robinson), Olivia's former chauffeur and a key suspect in her murder; and Detective Broussard (Tony Franciosa), a police investigator who, like Harper, was once involved with Iris. This was
Coral Browne's first film after her marriage to actor
Vincent Price in 1974. ~ Mark Deming, All Movie Guide
