The Spirit chronicles the adventures of a masked vigilante who fights crime with the blessing of the city's police commissioner Dolan, an old friend. Despite the Spirit's origin as detective/criminologist Denny Colt, his real identity was rarely referred to after his first appearance, and for all intents and purposes he was simply "The Spirit". The stories are presented in a wide variety of styles, from straightforward crime drama and noir to lighthearted adventure, from mystery and horror to comedy and love stories, often with hybrid elements that twisted genre and reader expectations.
