Last episode with Karl Held as David Gideon.
Last of four appearances by film actress Barbara Lawrence, who had appeared on Perry Mason between 1958 and 1962. This appearance aired in January, just months before she retired from acting altogether. Her final appearance was in an episode of The Tall Man (1960) called Trial by Fury (1962).
One of the few Perry Mason cases after the first season to go to a jury trial and one of the very few times that Perry delivered an argument to the jury.
Mason is in the midst of receiving a kiss on the mouth from his client just as the epilogue of the program returns from commercial.
