Gladys Doyle (Louise Fletcher) is tasked with driving to a remote cabin and picking up a package for her boss. Her car breaks down in the pounding rainstorm and she seeks shelter at the nearest cabin she can find. The man does not want to let her in saying he has "neither a heart or a phone". But then he suddenly changes his mind, lets her in, and tells her to go in the next room if she wishes to take off her wet things and that he will take a look at her car when it gets light? Is this about to become the case of the lecherous log cabin guy? No, because said log cabin guy leaves while Gladys is changing. When she emerges she looks for the man, and in another bedroom finds a different man dead on the floor, a gun next to his body. She leaves the cabin and returns to LA.
When Gladys gets back her boss, author Mauvis Meade, discusses the situation with her and absolutely DOES indicate that there was a package and Gladys was there to pick it up at her direction. But when the police apprehend Gladys for killing this guy she says she has never seen before, Mauvis Meade is all - Package what package? Gladys is a person with a great imagination and she's a liar! Even without Perry on the case, a lesser lawyer would have to ask why Mauvis kept somebody in her employ that she held as having such poor character.
This episode of Perry Mason goes in a most unusual direction, and it was interesting how the district attorney AND the judge were OK with sacrificing Gladys' possible acquittal in the interest of keeping government secrets. Only Perry objected, which I'd expect.
I'd recommend it.
