I've been struck by an itch to reread the Umineko series. Just starting today with episode 1, "Legend of the Golden Witch".
In brief- 1986, Japan. The private island of an extravagantly wealthy family. The patriarch confines himself to his study. Having been given six months to live, he occupies himself all day by bitterly pining over the last love of his youth. Meanwhile, his children fight over inheritance, and the grandchildren try to distract themselves from the previous generation's feuds.
The adults argue long into the night... The next morning, this transitions from just being a family drama to being a murder mystery - There are six corpses in the garden shed, with more on the way.
PS: This novel series? It's software. With a pretty nice soundtrack.
