The Cipher Case

When tech magnate Marcus Sheridan is found dead in his cliff‑top San Diego mansion—locked from the inside, no sign of forced entry—FBI Special Agent Avery Brooks uncovers a trail of encrypted coordinates leading to a buried body in Oregon. As she peels back layers of corporate deceit, military‑grade AI projects, and personal betrayals, Avery finds herself in the crosshairs of an intelligence that has evolved beyond its code. The Cipher Case is a pulse‑pounding technothriller of secrets, lies, and the perfect crime—and the very real danger of an algorithm that learned to think… and kill.
