Case Closed, Vol. 51

When ace high school detective Jimmy Kudo is fed a mysterious substance by a pair of nefarious men in black--poof! He is physically transformed 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.

Digging for clams at the beach, the Junior Detective League digs up a mystery instead. Did a depressed beachgoer commit suicide, or was he murdered by one of his friends? Then detective Richard Moore faces a challenge beyond his crime-fighting abilities: taking care of his ex-wife's new kitten! But the pesky furball leads him to the clues he needs to solve an impenetrable code. Could there be a new detective in town--one even cuter than Conan?
