Live Your Best Lie

The novel explores how well people know themselves and others. I'm curious whether this theme evolved during writing or was planned from the start.

The story kept me guessing, but I kept flipping between suspects. Did others feel the same uncertainty or was there someone they suspected early on?

The narration added layers to the suspense, but I'm wondering if the pacing or clues were intentionally designed with audio in mind. Did the format shape any storytelling choices?
