He is the author of the memoir, Blue Blood that begins with his first days on the street as a cop in the New York Police Department and goes back three generations. His great-grandfather was an "officer of dubious integrity" during the Tammany-era NYPD. Conlon also wrote the "Cop Diary" columns in The New Yorker and is a graduate of Harvard. One reviewer writes, "No one has written a book that grabs readers by the scruff of the neck and tells them what the life of a cop is really like as well as Edward Conlon."
