  The Critic's Choice: The Best of Crime & Detective TV....Buy this book
  New York: Harmony Books, 1988.
  A rollicking read, full of outrageous opinions, defiant defenses and embarrassing admissions, by a Who's Who of crime writers, TV critics and others, rounded up by Max Collins and John Javna. A hoot. Even the throwawy lines are keepers. Highly recommended.

  Television's Private Eye: An Examination of Twenty Years Programming of a Particular Genre, 1949-1969
  Ann Arbor, Michigan, U.S.A.: University Microfilms International, 1973.
  Seminal work of the TV private eye, listing almost every private eye show on American television from 1949-1969. Includes info on production, sponsors, time slots, plot synopsis, even sponsors. Although now dated, it captures the sense of popularity of a genre that is now almost, sadly, non-existent.
