Episode 7 of Detective Conan (Case Closed)

Trivia

 * This marks the first time Ran becomes suspicious of Conan's identity.
 * The outfit Ran wears in this episode is the same as the one she wore to Tropical Land in the beginning of the series.
 * As this case took place on the 10th day since Shinichi became Conan, this means Shinichi was shrunk on February 9th.
