けちんぼフレッドを探せ! (扶桑社ミステリー)

The book manages to be both funny and thrilling at the same time. I'm curious what influenced the choice to blend these tones so seamlessly.

Her unpredictable behavior kept me laughing but also made me wonder how much of her character was planned versus spontaneous.

The town feels so vivid and real—was it based on a real place or entirely imagined? I’d love to hear about the world-building process.
