The Acquittal(1923)

"WHO KILLED ANDREW PRENTICE? That is the question you will have to solve in THE AQUITAL."

Overview

When a wealthy man is found murdered in his bedroom, one of his two adopted sons is arrested and charged with the killing. However, the verdict at his trial is an acquittal. Since the police don't seem to be particularly interested in finding the real killer, the dead man's daughter-in-law--the wife of the adopted son who wasn't charged--takes it upon herself to solve the crime.
