3x4 - Perry Mason

Mitsuo Kamuri has been seeing a great deal of Grover Nichols, son of wealthy businessman Hudson Nichols. Nichols doesn't approve of his son's relationship and when Mitsuo is "caught" with a string of valuable pearls belonging to Mrs. Nichols he agrees to drop all charges provided she stops seeing his son. Things then get even more complicated when Mitsuo's uncle, who had originally strung the pearls. is found murdered. The death has been made to look like hara-kiri but the police are not fooled.
