Carter Gilman seeks Perry Mason's assistance in finding out why a female private detective is blackmailing the wife of a friend. Gilman isn't using his real name however and the 'friend' needing help is actually himself. Gilman has a daughter, Muriell, from a previous marriage and is now married to Nancy whose daughter Glamis is still living with them. After receiving a call from the Gilman women when Carter goes missing and Muriell finds money with something red on it in her father's workshop, Perry visits their home finding Carter's woodworking shop in disarray with $10,000 scattered on the floor with red stain on it. When Paul Drake tells Perry the Las Vegas private detective was found dead, Perry starts to piece together what may have happened. When Glamis' boyfriend Hartley Elliott tells Perry he saw Glamis running out of the workshop in the early morning hours, it seems he may have sealed the girl's fate. It's Carter Gilman however who is charged with murder. Written by garykmcd

Either the budget wouldn't allow for it or the script ran way over its hour format because this episode of Perry Mason mentions several characters including the victim herself who never make an appearance or have a line of dialog in the show. Not having the victim make an appearance and practically beginning the show with her dead already is an unusual departure from the Perry Mason paradigm.

Raymond Burr's client is Walter Kinsella who is charged with the murder of a female private detective who was engaged in a bit of blackmail regarding his stepdaughter Anne Helm and an inheritance she's in line for.

The writing of this story got a little too involved and too overplotted for my taste. I can't possibly go any further in describing this Mason episode. Let's just say that a private lie detector and William Hopper's Drake Detective Agency was working way overtime to solve this one. Oh, and Perry Mason is accused of withholding evidence.

A little too much in this Perry Mason story for the mind to digest.
