In Undisclosed Files of the Police: Cases from the Archives of the NYPD (Black Dog & Leventhal Publishers), the authors—a lieutenant with the department since 1981 Bernard J. Whalen, a retired detective and true-crime writer Robert Mladinich and veteran New York Post crime reporter Philip Messing—chronicle the most interesting, most notorious, most unbelievable, or most disturbing crimes in city history. The stories and images go back to the early 1800s when the Nightwatch, a handful of men who patrolled the streets in lower Manhattan from dusk to dawn, to the present-day force of more than 34,000, which patrols five boroughs of 320 square miles 24 hours a day.
