Afterwards, the master is found dead from a heart attack. Conan realizes he must've seen something that was impossible causing him that much of a fright.

A small three-story house is put up for rent in the neighbourhood and the Detective Boys decide to pass by it on the way home from school. Haibara tricks the real estate agent into giving them a tour of the inside and Conan notices you could see Mori's detective agency from the third floor window. The next day, they discover the house has been sold to an old couple and Conan finds them suspicious. He follows the old man to China town and into a back alley shop where he is discovered, but manages to flee. Conan takes a nap upon coming home and a man in black enters with a gun and shoots him. The old woman rushes to the agency calling out for Shinichi who Conan greets as his mother and the old man enters to reveal himself as Conan's father. It turns out, Shinichi's parents just wanted to find out if he really was doing okay in his current life.
