Detective Conan

Agasa and the Detective Boys are riding on a bus on a public holiday when, at exactly 2 p.m., they witness a man shoving another man off the roof of a nearby building. The bus starts before they can get out. When they get back at 2:20, an ambulance has just arrived, having been called by a pedestrian who almost was hit by the falling man. The man on the pavement is identified as Masaaki Ogata, a loan shark. As it takes on average 5-6 minutes for an ambulance in Tokyo to reach the site of an emergency, Conan asks when the call was made, and learns at about 2:10, right after the man hit the pavement. 10 minutes is a long time for someone to drop five floors, though. In the office of the loan shark signs of a struggle are found, and traces of someone who has been dragged from the balcony into the office. Also, there is a driver's license issued to Ryouhei Honda, and his glasses are found on the balcony outside of the railing.
