Stephen's insurance policy would be voided in the case of suicide,
Adam insists that Stephen killed himself and decides to undertake
his own investigation. Finally catching up to her husband, a
jealous Janet insists in participating in the investigation, and
Adam tells her that he believes Stephen was killed by someone
close to him. In private, Cecile accuses Sarah Frome, Stephen's
sister-in-law and the beneficiary of his insurance, of stealing
Eve's gun to make Stephen's suicide appear like murder.
Cecile demands that Sarah sign the insurance benefits over to her,
Sarah shoots her with Eve's gun and then immediately visits Adam
to provide herself with an alibi. Sarah tells Adam about Cecile's
blackmail attempt, and they return to Cecile's apartment, where
the wounded Cecile collapses. When Jimmy confesses to the murder
to protect Eve, Eve calls Sarah for help and Sarah sends her into
a police trap at Cecile's apartment.
Immediately after, Adam
visits Sarah, hoping to find Eve. Meanwhile, Janet, who has
decided to solve the case herself, visits Cecile and hears her
accuse Sarah in her sleep. At that moment, Sarah, who has slipped
away from Adam, appears at Cecile's bedside and is about to
eliminate Janet when Adam comes to her rescue. With the case
solved, both Adam and Janet take the credit and begin life as a
happily married couple.
