Context paragraphs:
The Girls (Cline novel): The Girls is a 2016 debut novel by American author Emma Cline.  It concerns the members of a cult that resembles the Manson Family.

Donald Shea: Donald Jerome Shea also known as "Shorty" (September 18, 1933 - August 26, 1969) was a Hollywood stuntman, actor and victim of the Charles Manson murders.  The location of his body was not discovered until 1977, nearly a decade after his death.  Manson family leader Charles Manson and family members Steve "Clem" Grogan and Bruce Davis were eventually convicted of murdering Shea.  Tex Watson, Bill Vance and Larry Bailey (alias Larry Giddings) were possible participants in the murder, but were never charged.

Manson Family: The Manson Family was a quasi-commune that arose in California in the late 1960s, led by Charles Manson.  They gained national notoriety after the infamous murder of actress Sharon Tate and four others on August 9, 1969 by Tex Watson and three other members of the Family, acting under the instructions of Charles Manson.  Group members were also responsible for a number of other murders and assaults, and the attempted assassination of President Gerald Ford.

Sandra Good: Sandra Collins Good (born February 20, 1944) is a long-time member of the Manson Family and a close friend of Lynette "Squeaky" Fromme.  Good's Manson Family nickname is "Blue", which was given to her by Charles Manson to represent clean air and water.

The Manson Family Album: The Manson Family Album is the first studio recording by American rock band Marilyn Manson.  It is a precursor to the band's debut studio album, 1994's "Portrait of an American Family".  It was produced by Roli Mosimann, and is composed of original takes and mixes of songs which would later be found on their debut.  However, the band's eponymous vocalist was unhappy with Mosimann's production, claiming it was too "smoothed and polished", and poorly representative of the band's established sound.  The majority of songs on "The Manson Family Album" were later re-recorded or remixed with Nine Inch Nails frontman Trent Reznor at the Record Plant in Los Angeles.  The album's title is a double entendre; it also relates to the commune of cult leader Charles Manson.

George Spahn: George Spahn (February 11, 1889 – September 22, 1974) was a rancher who once owned the Spahn Ranch near Chatsworth, Los Angeles, California.  Spahn (as did previous owner William S. Hart) rented the ranch to the movie industry to film Westerns.  At the ranch, he housed Charles Manson and his followers.  The 1969 murders of actress Sharon Tate and six others by Manson's devotees were allegedly hatched at the Spahn Ranch.  Manson persuaded Spahn to permit "the Family" to live at his ranch.  Manson ordered the Family women to have sex with the then nearly blind 80-year-old.  The women also acted as seeing eye guides for Spahn.  Spahn nicknamed all the Manson girls—Squeaky, Sadie Mae, Ouisch, etc.  According to Manson Family member Paul Watkins, notorious Mansonite Lynette "Squeaky" Fromme got her nickname because of the sound she made when Spahn ran his hand up her thigh.  Family member Charles Watson has written that his own nickname, "Tex", was given to him by Spahn, who recognized his Texas accent.

Tex Watson: Charles Denton "Tex" Watson (born December 2, 1945) is an American murderer who was a central member of the "Manson family" led by Charles Manson.  On August 9, 1969, Watson and other Manson followers murdered pregnant actress Sharon Tate and four other people at a house in Benedict Canyon, Los Angeles.  The next night, Watson traveled to Los Feliz, Los Angeles, and participated in the murders of Leno and Rosemary LaBianca, as part of Manson's "Helter Skelter" vision.  Watson was found guilty of murder and imprisoned in 1971.

Emma Cline: Emma Cline is an American writer and novelist, originally from California.  She published her first novel, "The Girls", in 2016, to positive reviews.

Helter Skelter (2004 film): Helter Skelter is a 2004 television film directed by John Gray based on the murders of the Charles Manson Family.  The film was a remake of the 1976 two-part TV movie.  Unlike the 1976 version, which focused mainly on the police investigation and the murder trial (as did the novel), this version focused mainly on Linda Kasabian's involvement with the Manson Family.

Charles Manson: Charles Milles Manson (born Charles Milles Maddox, November 12, 1934) is an American convicted mass murderer and former cult leader who led what became known as the Manson Family, a quasi-commune that arose in California in the late 1960s.  Manson's followers committed a series of nine murders at four locations in July and August 1969.  In 1971 he was found guilty of first-degree murder and conspiracy to commit murder for the deaths of seven people – most notably of the actress Sharon Tate – all of which were carried out by members of the group at his instruction.  Manson also received first-degree murder convictions for two other deaths.  Manson was originally sentenced to death, but his sentence was commuted to life imprisonment when California invalidated the state's death penalty statute in 1972.  He is currently serving multiple life sentences at California State Prison in Corcoran.
