Sota de Picas: Cazando al Jack Reacher de Lee Child (Serie En busca de Jack Reacher nº 12)

Jack of Hearts has a layered personality that kept me guessing. I'm curious what the creative process was behind developing this character's mystery.

The story had intense moments but also some slower stretches. I'm wondering if that was deliberate to build suspense or just my reading experience.

The story jumps between different perspectives and events, which felt very realistic. Did the author plan this interconnectedness from the start?
