Part 1 of 2 Haruna asks Mouri's help in tracking down her pager buddy, so she can return a valuable gift he gave her. Takagi assists by giving them the address associated with the pager number, where they find out her pager buddy Shuugo was a grandfather who recently passed away. They all stay for dinner, and overnight when it starts to rain. When the girls go to bed, they see a creepy shadow and scream. Then a thud is heard down the hall - a family member has been knocked unconscious. Then Haruna receives a message on her pager. Who could be responsible for all this?
