When ace high school detective Jimmy Kudo is fed a mysterious substance by a pair of nefarious men in black--poof! He is physically tranformed into a first grader. Until Jimmy can find a cure for his miniature malady, he takes on the pseudonym Conan Edogawa and continues to solve all the cases that come his way.

 

Conan stumbles upon his creepiest mystery yet, complete with a haunted house, a spooky pair of twins, and... a giant spider? Are Conan and his friends really under attack by restless spirits, or was this web of terror spun by human hands? Good thing Harley Hartwell's there to help with the case! Then the Junior Detective League goes camping--only to run afoul of a gang of crooks, a labyrinth of caves, and a whole bunch of angry bats!
