Nero Wolfe is a fictional detective, created in 1934 by the American mystery writer Rex Stout. Wolfe's confidential assistant Archie Goodwin narrates the cases of the overweight detective genius. In total, Stout wrote 33 novels and 39 short stories from 1934 to 1974, with most of them set in New York City. Wolfe's residence, a luxurious brownstone on West 35th Street, features prominently in the series. Many radio, television and film adaptations were made from Stout's stories.

Created by author Jack Boyle, Boston Blackie was a master safecracker and hardened criminal who served time in a California prison. Rehabilitated, he decided to use his knowledge of the underworld to fight crime as an amateur detective. Known as "an enemy to those who make him an enemy, friend to those who have no friend", Boston Blackie's exploits were adapted to film, radio, and television.
