1015

The Detective Boys witness Detective Chiba buying a large amount of food at a convenience store and follow him. They entered an ordinary apartment building. They thought he might have come to see a friend, but Conan deduced that the apartment was newly built and Detective Chiba was on a stakeout there. He follows him and finds Detective Takagi there as well. The Detective Boys ask him to let them wait until the doctor comes to pick them up, and hear that the reason for the stakeout is the jewelry store robbery and murder that happened last week.
