As Far as She Knew

The slow reveal added to the suspense, but I wonder if the pacing was intentional to mirror the protagonist's own uncertainty. How did that choice shape the story's tension?

Her reliability is questionable, and it made me question how much of the story was true. Did this trust issue enhance the mystery for others?

I love when mysteries have subtle foreshadowing, but I missed some of these hints. Was the author intentionally planting red herrings?
