El secreto de la isla (La serie de Sandhamn nº 4)

The shifting viewpoints added layers of complexity, but I'm curious whether this was planned from the start or evolved during writing.

The story delved deep into character backgrounds, which made me wonder if that was necessary for the suspense or if it slowed the momentum.

The cold, bleak environment really amplifies the mood. I'm interested in whether the author drew from personal experiences or research.
