過ぎ去りし日々 (ハヤカワ・ミステリ文庫)

The way the past and present intertwine adds depth, but I'm curious whether this structure was planned from the start or evolved during writing.

His internal conflicts about justice and morality made the story really resonate. I wonder how much of that was inspired by real historical events.

The details felt authentic, but I'm curious if the author did specific research or drew from personal experience to craft the era.
