Distinguished Family's Consecutive Accidental Death Case
Chapters 150-153
Deaths: 2
Days: 2 (I think? This one is tough and might need to be revisited in another format or with another translation. There's a reference to someone's alibi being "two days ago around x time", but the actual events of the case don't make it clear that the entire investigation isn't happening entirely in one night. Right now, I'm saying 2 though.)
Essential: Yes, in the "Shinichi's character arc" way. I don't think anyone would argue with me against that. Also because I think it's a huge point in Heiji's character arc.
Notes: this case also includes the beginning of the good old "Hey Kudo-- I mean Kudoi, persistence! As in wow this kid sure is persistent!" that becomes Heiji's whole thing. Also has a bit of hilarious indicators of Heiji having a crush on Kudo (literally got hearts when he talks to him, the damn disaster bi of a teenager) that tie in nicely to Kazuha thinking "Friend Kudo from Tokyo" is a girl later.
