  Title: Piece of My Heart (novel)
  Passage: As volunteers clean up after a huge outdoor rock concert in Yorkshire in 1969, they discover the body of a young woman wrapped in a sleeping bag.  She has been brutally murdered.  The detective assigned to the case, Stanley Chadwick, is a hard-headed, strait-laced veteran of the Second World War.  He could not have less in common with - or less regard for - young, disrespectful, long-haired hippies, smoking marijuana and listening to the pulsing sounds of rock and roll.  But he has a murder to solve, and it looks as if the victim was somehow associated with the up-and-coming psychedelic pastoral band the Mad Hatters.  In the present, Inspector Alan Banks is investigating the murder of a freelance music journalist who was working on a feature about the Mad Hatters for MOJO magazine.  This is not the first time that the Mad Hatters, now aging rock superstars, have been brushed by tragedy.  Banks finds he has to delve into the past to find out exactly what hornets' nest the journalist inadvertently stirred up.
  Title: Erethism
  Passage: Erethism or erethism mercurialis is a neurological disorder which affects the whole central nervous system, as well as a symptom complex derived from mercury poisoning.  This is also sometimes known as the mad hatter disease.  Historically, this was common among old England felt-hatmakers who used mercury to stabilize the wool in a process called felting, where hair was cut from a pelt of an animal such as a rabbit.  The industrial workers were exposed to the mercury vapors, giving rise to the expression “mad as a hatter.”  Some believe that the character the Mad Hatter in Lewis Carroll's Alice in Wonderland is an example of someone suffering from erethism, but the origin of this account is unclear.  The character was almost certainly based on Theophilus Carter, an eccentric furniture dealer who was well known to Carroll.
  Title: Mad scientist
  Passage: Mad scientist (also mad doctor or mad professor) is a caricature of a scientist who is described as "mad" or "insane" owing to a combination of unusual or unsettling personality traits and the unabashedly ambitious, taboo and/or hubristic nature of their experiments.  As a motif in fiction, the mad scientist may be villainous (evil genius) or antagonistic, benign or neutral; may be insane, eccentric, or clumsy; and often works with fictional technology or fails to recognize or value common human objections to attempting to play God.  Some may have benevolent or good-spirited intentions, even if their actions are dangerous or questionable, which can make them accidental villains.
  Title: Rules of origin

  Title: Mad River Road
  Passage: Mad River Road was the first overland route between Dayton, Ohio and Cincinnati, Ohio.  It was cut by Daniel C. Cooper in 1795 to provide access to the new town of Dayton and the "Mad River Country" northeast and north of Dayton.  It was located at the mouth of the Mad River in the Symmes Purchase.  The survey, entered into the record by Cooper and Dr. John Hole, extended Harmer's Trace north from near Cunningham's Station on the Mill Creek to the mouth of the Mad River, establishing the earliest road between Cincinnati and Dayton.  Cooper, a surveyor and miller, was instrumental in the early settlement of Dayton, and Dr. Hole, the first physician in Montgomery County, established his cabin in 1796 near the now-extinct town of Woodburne on Mad River Road.
  Title: Country of origin

Country of origin labelling is also known as "place-based branding", the "made-in image" or the "nationality bias."  In some regions or industries, country of origin labelling may adopt unique local terms such as terroir used to describe wine appellations based on the specific region where grapes are grown and wine manufactured.
  Title: Homeland
  Passage: A homeland ( "country of origin" and native land) is the concept of the place (cultural geography) with which an ethnic group holds a long history and a deep cultural association – the country in which a particular national identity began.  As a common noun, homeland, it simply connotes the country of one's origin.
