An estranged couple embroiled in a nasty divorce and living in different parts of town are murdered on the same night with the same gun.
Although the murder weapon has not been found, the ballistics report shows both victims have been killed by the same gun which leads police detective, Conroy, to assume the victims were murdered by the same killer. However, each suspect he interrogates has motive to kill one victim but not both.
When the gun surfaces and a witness places it in the hand of Susan Wainright, the victims’ daughter, Detective Conroy arrests her.
Positive Susan is innocent, Susan’s lawyer hires private detective, David Nance, to find viable alternate suspects. As David digs into the suspects, he finds, as did Detective Conroy, that Susan is the only one with means, motive and opportunity to commit the murders.
Did Susan kill her parents? The prosecutor’s case seems air tight. To David’s dismay, it looks like this will be the first case that he will lose.
