Butterfly Blues is a children’s mystery novel in the Nancy Drew and the Clue Crew series, written under the pseudonym Carolyn Keene and illustrated by Peter Francis. In this story, Nancy Drew and her friends Bess and George visit a butterfly museum called Flutter House during a school trip. They are excited to see rare and beautiful butterflies, including a prized Blue Morpho.
However, the excitement turns into a mystery when the rare Blue Morpho butterfly suddenly goes missing. With many possible suspects and few clear clues, the Clue Crew begins investigating the theft. Nancy and her friends must carefully observe, question people, and follow small hints to uncover who took the butterfly and why. The story is a light, fast-paced detective adventure focused on teamwork, observation skills, and solving a small but puzzling crime in an engaging museum setting.
About the Author
Carolyn Keene is not a single person but a pseudonym used by multiple writers over many decades for the Nancy Drew series. The character of Nancy Drew was originally created by the Stratemeyer Syndicate, which hired different ghostwriters to produce books under the same name to maintain consistency in the series. One of the most influential early writers was Mildred Wirt Benson, who helped define Nancy Drew’s independent and curious personality. Over time, many authors contributed to the series, making Carolyn Keene one of the most recognizable pen names in children’s mystery literature.
