(Found) Sci-fi about an investigator with the last name "Clattuck"

[Sparkchaser]

I believe the book was written the 60's. A young man after graduating from academy becomes an investigator trying to solve his father's disappearance,the murder of a female classmate ,and an attempt to overthrow his family from control of a planet in their keeping as a preserve. As all of this is happening ,he also has to stop an attempt to have have him downgraded to "co-Clattuck" which will end the investigations and force him from his rank in the family and remove him from his holdings.
