Perry Mason is retained by a woman in an admirable attempt to break up her husbands romance with an attractive divorcee. After buying stock in a company, Mason creates business difficulties to bring out the worst in the other woman. The plan works, but it also creates other events to start moving, and the divorcee becomes an accomplice to a murder pointing to Masons client. In the preliminary hearing, Burgers case is unbelievably sloppy, but Mason has to play the jury trial strictly by ear. He is lucky to pull this one off.
