"The Noon God" begins with the murder of author J. Caesar Fortune, and how it affects his two (living) daughters, Lucy and Mona. We go along with Mona as she recounts how her father didn't like her husband, and how he was generally abusive of those around him. In other words, despite us being told that Fortune is a brilliant author, he comes across as an all-around prick.
Sadly, the "whodunnit" really ticked me off ... and not due to any overall fondness for the character in question. It just seemed like a cheap cop-out to get the book over with.
