With its blend of humor and critique on the medical profession, the book explores themes of ethics in medicine and the unintended consequences of technology. The plot follows Dr. Klinghammer, an investigator for the Malpractice Board, who is tasked with probing the complaints about these dubious machines, which purport to diagnose ailments in a fun but potentially misleading way.
