Case Closed Case Closed, Vol. 21, (Paperback)

Can Detective Conan crack the case...while trapped in a kid's body?

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.

Conan and Rachel take to the skies! But their transcontinental detective mission runs into unexpected turbulence when a murder is committed on board their passenger plane. Rachel doesn't think she can solve the case before the plane lands, but then she receives a little in-flight assistance...from none other than the long-lost Jimmy Kudo! Has Conan finally returned to his teenage self? And if so, how? Whatever the answer, Rachel's in for a bumpy flight!
