死者の身代金 (現代教養文庫―ミステリ・ボックス)

The setting feels so authentic, but I wonder what choices were made to keep the story engaging without sacrificing real details. Did any historical sources influence the plot?

I was really engrossed at the start, but the middle chapters felt a bit slow for me. I'm curious if that was meant to build suspense or develop characters.

The medieval setting adds so much atmosphere, but I wonder what drew the author to this era specifically and how much research went into creating its details.
