Junk Mail is a 1995 book by Will Self published by Bloomsbury Publishing.
 It features pieces of writing centred on drugs and the counter-culture, taken from writing in British newspapers such as "The Guardian", "The Observer" and "The Independent".
 It incorporates a wide range of writing, such as an article on drug dealers in the East End of London called "New Crack City", reflections on the nature of slacking, travel essays on whirling dervishes in Turkey as well as life in Israel and Ulster, and a script of sorts for a rock video by the group Massive Attack.
 It also includes dialogues with Martin Amis, J. G. Ballard and William Burroughs and profiles on Thomas Szasz, Damien Hirst, Tim Willocks and Bret Easton Ellis.
Patrick Bateman
Patrick Bateman is a fictional character, the villain protagonist and narrator of the novel "American Psycho" by Bret Easton Ellis, and its film adaptation.

Camden College (fictional college)
Camden College is a fictional liberal arts college, which appears in the works of Bret Easton Ellis, Jill Eisenstadt, and Jonathan Lethem.
 Whereas Ellis' Camden College is located in New Hampshire, Lethem's Camden is in Vermont, and is notable for being the most expensive college in America.
 All three of the writers attended Bennington College, which is really located in Vermont, and was at one time notorious for being the most expensive college in America.
 Bennington graduate Donna Tartt uses the same Bennington-inspired backdrop for her 1992 novel "The Secret History", but for her it is "Hampden" College.
 However, Eisenstadt and Lethem uses 'Camden' in "From Rockaway" (1987) and "The Fortress of Solitude" (2003), respectively.
