Finders keepers / Stephen King.

"A masterful, intensely suspenseful novel about a reader whose obsession with a reclusive writer goes far too far--a book about the power of storytelling, starring the same trio of unlikely and winning heroes King introduced in Mr. Mercedes"--""Wake up, genius." So begins King's instantly riveting story about a vengeful reader. The genius is John Rothstein, an iconic author who created a famous character, Jimmy Gold, but who hasn't published a book for decades. Morris Bellamy is livid, not just because Rothstein has stopped providing books, but because the nonconformist Jimmy Gold has sold out for a career in advertising. Morris kills Rothstein and empties his safe of cash, yes, but the real treasure is a trove of notebooks containing at least one more Gold novel. Morris hides the money and the notebooks, and then he is locked away for another crime. Decades later, a boy named Pete Saubers finds the treasure, and now it is Pete and his family that Bill Hodges, Holly Gibney, and Jerome Robinson must rescue from the ever-more deranged and vengeful Morris when he's released from prison after thirty-five years."
