Judith McMonigle Flynn is scheduled for a hip replacement. Instead of looking ahead to her new mobility, she's worried. "Routine surgery" recently cost a local actress and a star baseball pitcher their lives. Though Judith smells malice, she successfully survives her operation--but another patient isn't so lucky. Stuck in this chamber of Hippocratic horrors, Judith feels compelled to get to the bottom of what could be the worst malpractice case ever recorded ... or perhaps something much more sinister. The worst diagnosis of all is the one that suggests Judith's curiosity is terminal ... and that a killer is saving a last lethal dose of medicine for her.
