皮膚の下の頭蓋骨 (ハヤカワ・ミステリ文庫 (HM 129‐2))

The detective's internal conflict added depth to the mystery, but I wonder if the author drew from personal experiences or research into mental health.

The gradual revelation of clues kept me on edge, but I was curious whether the author intentionally paced it this way to enhance the psychological tension.

The British atmosphere added a layer of authenticity and gloom. I wonder what inspired the author to choose this particular locale.
