From The Perry Mason TV Show Book
Mildred Kimber gets mixed up with some “bad seeds” who try to con her weak-willed husband out of her rare orchid business via a fixed poker game. When a couple of these jokers are poisoned, Mil is sent to the slammer.

Although Hamilton Burger threatens to charge Perry with everything from unethical conduct to manslaughter, it doesn’t keep Perry from making bold moves. As usual, he and Paul Drake are at the scene of the crime before the police are, wearing out their hankies handling evidence without leaving their fingerprints.
+ Who writes these things? Almost nothing in this description has anything to do with the actual plot of this episode. No jokers are poisoned, Perry is not charged with manslaughter. Drake is not at the scene of the crime. Etc. Submitted by Wick 6/22/2022.
