Detective Moore, Rachel, and Conan pay a visit to an old woman. She decides to take them to her grandson, but he's found dead when they get into the house. The bathroom door is locked however. How could this have happened? Rather than use detective Moore for the case, Conan solves this one as himself. (Source: Wikipedia)
