The General's Daughter: by Nelson Demille.

No matter how much she achieves, she could never achieve one thing she desperately needed as a child, her father's approval and love. He is a high profile general and a selfish man in that his career, his standards, his name is everything. Perhaps a male heir would beat him at his own game, perhaps not, who knows! But a daughter has no chance whatsoever no matter how high an achiever in his own field, because she has other needs too, of love and admiration, and if she does not get them from him she could only go frigid and die within or do something that would inevitably blot the father's escutcheon, since respectable ways of a happy life with love do not match requirements of a life with high achieving career if you are a woman, not in west, certainly not in military.

So when she is dead in a position incompatible with her father's position, he must order an inquiry but makes his requirements clear, hush. And the setup of the inquiry is as suitable for the purpose, or so those that arranged it think.

Only, those that are given the job have more of a conscience and integrity. They will go to the end to discover truth, and will not hush it up. And truth is, however much others in the base hated her or whatever, for whatever reason, it is her own father that is responsible for her murder, in a more literal way than the slow torture of her life from childhood on.
