The Hanged Man’s Song by John Sandford

When a brilliant hacker known as Bobby is found murdered, Kidd — artist, computer genius, and occasional thief — knows the killer has stumbled upon something far more dangerous than stolen code. Bobby’s laptop is missing, and whoever has it now controls access to powerful government secrets and the identities of people who’d kill to protect them. With his partner LuEllen, Kidd dives into a cyber-world of espionage, assassins, and political manipulation, where betrayal lurks behind every digital shadow. The Hanged Man’s Song is a sharp, high-stakes thriller where intellect becomes the most lethal weapon of all.
