A character type that's popular with children's mysteries and adventures that contain mystery elements.

The Kid Detective is part Snooping Little Kid, part Amateur Sleuth. He is a child who lives to snoop and asks suspicious adults (or any important witness) to piece together what happened.

He'll always snoop around without the adults' knowledge. He must figure out how to investigate without getting caught by the criminal, while eluding trouble from authority figures. If he's caught by authorities added restrictions will be placed, so now he has to break even more rules to keep looking. If he's captured by the criminal he will be Bound and Gagged, and must either break free, call for help, or be freed by a fellow Kid Detective.

Obviously he's more adventure-oriented than adult detectives, with a focus on snooping rather than interrogation. Kids can't interrogate suspects anyway, so tricking them into revealing something is his best option.

And while an adult can go straight to the authorities with evidence, this kid often struggles with telling them what he experienced. He has to let them know what's up in a roundabout way, or expose it somehow. Rare is the one trusted by adult detectives, and can go to them directly.


Examples of Kid Detective include:

Anime and Manga

  • The CLAMP School Detectives
  • Death Note has the kids from Wammy's House, particularly "Near". They're orphan geniuses raised to find the kid that will one day become L's successor.
  • Detective Conan:
    • "Conan Edogawa" is a 16-year old de-aged down to six. He has to find ways of cluing adults in disguised as being a nosy six-year-old. Though some flashbacks to his childhood do have him being genuinely helpful in some of his dad's investigations. . .
    • The "Detective Boys" Ayumi, Genta, and Mitsuhiko.
    • Ai Haibara too. She's actually Shiho "Sherry" Miyano, also a teenager de-aged down to six — though she was a Hot Scientist rather than a sleuth.
  • Fuyuki from Keroro Gunsou in a few episodes.
  • Lupin III's Baranco, a one-shot character.
  • Majin Tantei Nougami Neuro has Yako Katsuragi. Although a talented head of the Detective Agency, she's simply a front for the demon Neuro who does all the investigations.
  • Akise from Mirai Nikki
  • Mythical Detective Loki Ragnarok has the eponymous character
  • Narutaki from Steam Detectives, heir to Steam City's greatest detective.
  • Tantei Gakuen Q has budding sleuths compete to be Detective Morihiko's successor. Out of them Kyuu, Megu, Ryu, Kazuma, and arguably Sakurako and Kuniko are in the right age range (Kintaro is a bit older than them)
  • To Aru Kagaku no Railgun has four girl detectives.

Comic Books

  • The Dead Boy Detectives
  • Little Lulu's Tubby occasionally acted as one, whenever Lulu needed his help with a problem at her house.

  • Enid Blyton wrote many such sleuths, including the Famous Five, the Secret Seven, and the Five Find-Outers.

It turns out she's the murderer, having decided to kill her grandfather over his not getting her ballet lessons. She chose to investigate to get further attention from her family and the police. The subversion comes from the fact that readers were led to believe she was a genuine Kid Detective.

He barely manages to excuse himself when the suspect and his menacing father arrive early. Afterward, the experience weighs so much on him that he confesses to his parents what he was up to. They give him a firm lecture about taking such risks, then playfully suggest that since he's done it, he might as well contact McGee to give his report.

"Now, Mama, Papa, and sir," said Ramses, "please withdraw to the farthest corner and crouch down with your backs turned. It is as I feared: we will never break through by this method. The walls are eight feet thick. Fortunately I brought along a little nitroglycerine--"
