Nathaniel Dusk, a private investigator, is the titular protagonist of two four-issue-long comic-book miniseries by DC Comics.

He had been watching I Spy, a series starring Culp, when the idea of Nathaniel Dusk came into his mind.

Dusk fell in love with Joyce Gulino, a beautiful young saleswoman with two children, Jennie and Anthony.

[1] The 2017-2019 miniseries Doomsday Clock, by Geoff Johns and Gary Frank, portrays Nathaniel Dusk in the DC Universe as a noir film character portrayed by fictional actor Carver Colman.
