I think the ultimate book on this subect would be "Prime Time and Misdemeanors: Investigating the 1950s TV Quiz Scandal A D.A.'s Account" by Joseph Stone, who was involved with the case. This book was published over 30 years ago, and is no longer in print, but anyone interested in it may find a used copy someplace,
You can find a used copy on my bookshelf.
I read it on archive.org after the 2023 passing of Robert Noah, whose novel on the same subject was also available there.
