Editing 87th Precinct (section)

==Setting==
The series is based on the work of the police detective squad of the 87th [[Organization of the New York City Police Department#Police precincts|Precinct]] in the central district of Isola, a large fictional city obviously based on [[New York City]].  Isola is the name of the central district of the city (it fulfills the role of the borough of [[Manhattan]] within New York City).  Other districts in McBain's fictionalized version of New York broadly correspond to NYC's other four boroughs, Calm's Point standing in for [[Brooklyn]], Majesta representing [[Queens]], Riverhead substituting for [[the Bronx]], and Bethtown for [[Staten Island]].

Other recognizable locations that correspond to New York City landmarks are Grover Park ([[Central Park]]), Sand's Spit ([[Long Island]]), the rivers Harb ([[Hudson River|Hudson]]) and Dix ([[East River]]), neighborhoods such as The Quarter ([[Greenwich Village|The Village]]), Devil's Break ([[Spuyten Duyvil, Bronx|Spuyten Duyvil]]), Stewart City ([[Tudor City]]), and Diamondback ([[Harlem]]), and specific places such as Buena Vista Hospital ([[Bellevue Hospital|Bellevue]]), Ramsey University ([[New York University]]), Hall Avenue ([[Fifth Avenue]]), Jefferson Avenue ([[Madison Avenue]]), and the Stem or Stemmler Avenue ([[Broadway (Manhattan)|Broadway]]).  

The 87th Precinct has 16 detectives on its regular roster and is said to have the highest crime rate in the city and the busiest Fire Department in the world. Every single 87th Precinct novel begins with a disclaimer:

"''The city in these pages is imaginary.''<br>
''The people, the places are all fictitious.''<br>
''Only the police routine is based on established investigatory technique.''"
