whydunnit
Reason-focused crime story
A whydunnit is a mystery story where the perpetrator's identity is known from the start, and the puzzle centers on understanding their motive or method.
The term plays on whodunit, shifting the question from "who did it?" to "why did they do it?": Columbo is the classic whydunnit—you watch the detective piece together the how and why.
