A WOMAN'S SECRET is a melodramatic noir style mystery based on a Vicki Baum story, played in florid fashion by MAUREEN O'HARA, MELVYN DOUGLAS and GLORIA GRAHAME, all of whom are a bit over-the-top under Nichols Ray's direction.
O'Hara is the tough ex-singer promoter of the singing career of Grahame, and plays some of her argumentative moments as though she's Joan Crawford brandishing a gun in "Mildred Pierce". She gives the whole part a surface temperament of angry emotions that doesn't quite ring true, alternating with sweeter moments. She does get a chance to demonstrate her pleasant singing voice, unlike Grahame who is dubbed.
After confessing to shooting Grahame during a heated argument over Gloria's decision to quit her career, she tells her story in flashback. Her good friend, MELVYN DOUGLAS, also fills in some of her background with another flashback, a la "Mildred Pierce" and "Laura" techniques.
Douglas is a piano accompanist who refers to Grahame's singing voice as "a voice with hormones". He has some clever lines and plays the film's most believable character. BILL WILLIAMS shows up midway through the story as Grahame's friend (in a wasted role) who's anxious to see that O'Hara gets punishment for shooting Grahame. "I hope they hang her!"
Unfortunately, it's also at the midway point that the story starts to lose interest, as the mystery is slow to clear up and the story rambles on with still another flashback full of exposition by Douglas about past events.
A tighter script without all the flashbacks and a more direct way of telling the story might have made for improvements. As it is, it has a promising start but loses its way, stumbling in a strand of back stories long before any final explanation is given.
