This was obviously a Claudette Colbert vehicle. "The Secret Heart" is not shown often these days, and it's a good melodrama, typical of the era. Robert Z. Leonard directs with panache this story about a woman's sacrifice and decency.

We first meet Leola (Lee) aboard a luxury liner with Chris Matthews, who is obviously in love with her. Lee has been asked to marry Chris' best friend Larry, and Lee feels her duty to go ahead with her plans to marry this troubled man, a widower with two small children. What Lee gets from that union is much more than what she bargained for. Larry turns out to be an embezzler at the bank he works for. His guilt will make him commit suicide.
Lee decides the right thing to do is to repay Larry's debts and hide from the young children the fact about their father's suicide. Chase, the boy, is a grounded person and he goes on with his life. Young and fragile Penny, who adored her father and the music he played, never recovers and retreats into a cocoon; she becomes a troubled girl that only finds comfort in playing the piano just to imitate her father.
Claudette Colbert does wonders playing the courageous Lee. She caters to the children and becomes a successful real estate agent. Of course, as the stereotypical step-mother of all dramas, she is not appreciated by Penny, the girl that carries a grudge toward Lee. Walter Pigeon is the man who has loved Lee forever, but he is too decent to even come close to her. June Allyson is perfect as Penny, the neurotic girl who will find the truth about her father's fate at the end. In minor roles we see Robert Sterling, Patricia Medina, Richard Derr and Lionel Barrymore.
This film is well crafted and acted under Mr. Leonard's ti
