The Firm (novel): The Firm is a 1991 legal thriller by American writer John Grisham.  His second book, it was his first widely recognized book; in 1993, after selling 1.5 million copies, it was made into a film starring Tom Cruise and Gene Hackman.

The Tumor (short story): "The Tumor" is a short story by John Grisham, telling about the focused ultrasound process through the case of a fictional character named Paul.  This story was not released through Grisham's usual publisher, but instead was published for a free eBook on the website of the Focused Ultrasound Foundation, on whose board Grisham serves.  Grisham's purpose in writing this short story was to increase awareness about the promising new medical therapy.  The use of focused ultrasound is not yet approved for use on brain tumors, but "The Tumor" takes place in a time when the therapy is in regular use.  Unlike most short stories, the story is as much informational as narrative, and includes medical illustrations and brain scan images.  The book's cover includes the subtitle "A Non-Legal Thriller". On Grisham's website, in a letter introducing "The Tumor", Grisham states "It's the most important book I've ever written."
