Famous Detectives in Children’s Books

Written by SpyKids

What sleuths get kids excited about reading? Let’s dive into the world of famous detective teams and sleuths in children’s literature!

Mystery novels are among the most beloved literary genres, captivating readers of all ages. Many children love thrilling stories where detectives are hot on the trail of a mystery, allowing them to solve clues and get caught up in the excitement. The era of children’s detective stories begins around age 8, when kids start reading independently and discovering exciting book series. While Sherlock Holmes, Hercule Poirot, or Miss Marple are famous detectives in adult literature, children often prefer sleuths their own age. This age-related connection makes it easier for kids to immerse themselves in the detective adventure. For younger fans, detective stories might feature animal protagonists and be spiced with humor. But which child detectives are especially popular? Who are the famous sleuths in classic children’s books and series? We’ve done some investigating for you!

The Three Investigators

Who doesn’t know them? The three young detectives—Justus Jonas, Peter Shaw, and Bob Andrews—”take on any case” and solve “mysteries of all kinds.” Their trademark is their business card with the three question marks in white, red, and blue, and their headquarters is a cleverly equipped trailer on a junkyard in Rocky Beach, California. Besides books, there are also highly successful audio dramas, films, video games, comics, and more. Since 1999, “The Three Investigators Kids” series has catered to a younger audience, with the trio being just 10 years old and the stories being less scary and complex. The series was created by American author Robert Arthur in the 1960s, with crime master Alfred Hitchcock as the series’ patron. Many authors have contributed to the series, producing over 200 episodes, and it has been continued by German authors since 1993, much to the delight of fans.

The Famous Five

Enid Blyton’s youth book series is one of the most successful children’s book series worldwide. Unlike other detective series, and contrary to the German title’s implication, the young investigators are related. The smart Julian, the fun-loving Dick, and the caring Anne Kirrin are siblings. Their tough cousin Georgina, who prefers to be called George, and their dog Timmy make up the rest of the group. The “Famous Five” don’t have a detective agency; instead, they stumble into exciting adventures during their holidays, solving mysteries and riddles. The first 22 books were written by Enid Blyton, with subsequent volumes by other authors. Some short stories have been adapted for early readers. The series also includes films, comics, a TV series, and, of course, audio dramas.

The Boxcar Children

Created by Gertrude Chandler Warner in 1924, “The Boxcar Children” series follows the adventures of four orphaned siblings—Henry, Jessie, Violet, and Benny Alden. Initially living in an abandoned boxcar, they are eventually taken in by their wealthy grandfather, but they continue to use the boxcar as their base of operations for solving various mysteries. The series is beloved for its wholesome, family-centered stories and its emphasis on resourcefulness and teamwork. With over 150 books and counting, as well as adaptations into movies and a TV series, “The Boxcar Children” remain a staple of children’s mystery literature.

Nancy Drew

Since her debut in 1930, Nancy Drew has been one of the most famous girl detectives in literature. Created by Edward Stratemeyer and written by various authors under the pseudonym Carolyn Keene, Nancy Drew is a teenage sleuth who solves a wide variety of mysteries, often involving intrigue and danger. Her character has been updated over the decades to remain relevant to contemporary readers, and her stories have been adapted into movies, TV shows, and video games. Nancy Drew is celebrated for her intelligence, bravery, and independence, making her a role model for young readers.

The Hardy Boys

Also created by Edward Stratemeyer, “The Hardy Boys” series follows brothers Frank and Joe Hardy, amateur detectives who solve crimes and mysteries. First published in 1927 and written under the pseudonym Franklin W. Dixon, the series has been continuously updated to appeal to new generations of readers. The Hardy Boys’ adventures often involve action and suspense, and like Nancy Drew, their stories have been adapted into numerous media formats, including TV shows and

Master Detective Kalle Blomquist


Between 1946 and 1951, Astrid Lindgren wrote three children’s crime novels featuring detective Kalle Blomquist. Kalle is a huge fan of crime stories and admires famous detectives like Hercule Poirot and Sherlock Holmes. He often imagines himself as a great detective, much to the amusement of his friends. But his sleuthing skills become essential when he and his friends Anders and Eva-Lotta uncover dangerous jewel thieves in the first book, confront murder in the second, and deal with kidnapping and industrial espionage in the third.

Emil Tischbein

In 1929, Erich Kästner published “Emil and the Detectives,” the first “novel for children.” It follows 12-year-old Emil Tischbein, who is robbed during a train journey to Berlin. Fearing he might be blamed for a minor offense back home, he doesn’t report the theft to the police but instead pursues the thief himself, aided by a group of local boys and his cousin, Pony Hütchen. With Kästner’s signature humor and vivid Berlin setting, the adventure unfolds, culminating in a happy ending. The story was a huge success and remains a classic, though its sequel, “Emil and the Three Twins,” is less well-known.

These detectives are just a few examples of the many famous sleuths in children’s literature. There are also detective comics like “Tintin” :
