She says she poisoned her uncle and threw the evidence in a lake. The doctor takes the recording to Perry who talks to Nadine but soon finds himself the target of the police for interfering with evidence when he has a boy look for the bottle ...

Did You Know?


Less than 10% of the population of the world can detect the bitter almond smell that cyanide gives off as it off-gases. So there were long odds against Marian being able to know there was a bottle of it in the kitchen. See more »

Ethical dilemma and evidence tampering
4 July 2014 | by (Buffalo, New York) – See all my reviews

Young Christine White is Perry Mason's client in this episode. She gets to be that second hand because of her psychiatrist Barry Atwater who comes to Raymond Burr with an ethical dilemma. In a taped session White confesses to a murder by poison.

What does Atwater do. If he withholds evidence of a crime he could be arrested regardless of patient confidentiality. If he reports it and there wasn't a murder he could be sued. Those are the questions that would trouble Oliver Wendell Holmes let alone Perry Mason.

When he takes the case Burr finds himself accused of evidence tampering first by Ray Collins, second by William Talman. Now he has to find evidence and clear his name as well as White's.

He does find the murderer right at the very end and someone you'd least suspect. There were in fact any number of people who would like to have killed this particular victim who was Christine White's uncle.

I have a feeling that Perry Mason will take this murderer's case if that helps any in your guessing.
