In the afternoon of the next day, mithidima, kitako.


    Gao Cheng, with an umbrella in his hand, goes to a wealthy family''s residence and rings the doorbell after confirming "Aoping" on the doorplate.


    In the morning, he received a commission. The client was Mr. Aoping, the owner of the family. He wanted to ask him to investigate the strange death of his only son a year ago.


    After lunch, he hurried out of the door and was forced to put an umbrella by Xiao AI when he left.


    Gao Cheng has no choice but to look at the clear sky. Just at this time, the iron door opens automatically, and a middle-aged lady with lingering charm comes out. Seeing Gao Cheng, she is surprised and says, "are you?"


    "I am Gao Cheng, a city household entrusted by Mr. Aoping."


    Gao Cheng smiles politely. Different from normal times, he puts on a suit of mature style this time, which is not rude.


    "You are the famous detective. My husband told me," the lady said happily. "I''ll take the detective to my husband''s study. He''s still waiting..."


    "Excuse me."


    Gao Cheng keeps up with the ladies.


    From the outside, Aoping''s family only thinks that they are rich. They find that they are more luxurious than the invisible rich. They also have special housekeeper and maid services.


    Although it is not inferior to the villas he has seen before, it is not easy to have such a house in the high-end residential area of Tokyo.


    In the study, Gao Cheng meets the principal. His client, Aoping jiaozang, is 63 years old. She is much older than the hostess just now. Her hair is white and her face is wrinkled. She looks like an old man, and she doesn''t smile. She looks very serious.


    Waiting for the maid to serve coffee, Gao Chengji and the old man chatted face to face at the tea table in the study.


    "That''s what happened," oping explained. "The police said it was a prisoner of external invasion, but after such a long time, they couldn''t find the prisoner at all..."


    Gao Cheng crossed his fingers: "that is to say, a year ago, your whole family, except your son, were watching the video you took. As a result, your son was drowned in the swimming pool at home. The police judged that it was an outsider who committed the crime..."


    "Yes," oping said with a calm face, "the police judged that the time of my son''s death was between 9:00 p.m. and 10:00 p.m., and we watched videos in the living room from 7:00 p.m. to 12:00 p.m..."


    After listening to aopingjiaozang''s words, Gao Cheng thoughtfully looks at a picture on the tea table, which shows a wet male corpse with his hands and feet tied upside down and his mouth taped


    "I printed out the video when I found my son''s body," oping said. "It was the next morning, when the water in the swimming pool dried up, my son''s body was revealed, and the maid yelled..."


    "The maid found it?" Gao Cheng looks up and asks.


    "Yes, at first I thought it was his prank to scare us, but it was not a joke. People really died..."


    "Has your son offended anyone?"


    "Well, there shouldn''t be any outside, but there are some inside..."


    "Inside?" Gao Cheng put down the cruel looking picture, "at home?"


    "I think so, detective Chenghu," said aopingjiaozang with a gloomy face. "My son Xunwu was killed because some smart man thought he shouldn''t live in this house..."


    Gao Cheng frowned.


    It seems to be involved in strange events again


    "Why does Mr. opin think your son was killed by someone in the family? Everyone had alibi, didn''t they? "


    "The police say the same thing, but you see..." oping pointed to the photo and said, "my son was found wearing a white glove on his right hand, right?"


    "Well..."


    "Just two years ago, the housekeeper of this family had a car accident and fell off the cliff... This white glove is what he wears every time he drives..."


    Aoping jiaozang looks a little ugly.


    "Three days after my son was killed, I found the Butler''s left glove in this study! Someone must have hated the steward''s death, so... "


    "Hold a grudge?" Gao Cheng interrupted the old man, "didn''t he say an accident?"


    "Er, this..." the old man''s face was sweating, "it should be that some people thought that the accident was related to my son, so they would vent their anger..."


    "Then it''s your turn, old uncle, isn''t it?" When the door opens, Conan and Xiaolan suddenly appear at the door of the study


    "Who?" The old man was startled. Seeing Conan, he was shocked and said, "are you..."


    Gao Cheng also looked at Conan with black lines: "Why are you here?"


    "We came here with brother yingyou," Conan said with a smile, holding the back of his head, "because I heard that brother Chenghu was here, so I came to have a look. Hehe hehe..."


    Gao Cheng''s eyebrows jump.


    Hey, you head, how can there be this guy everywhere


    ……


    "Mother yingyou used to work as a maid here, so she took him to live here too..."


    In the living room and living room, Gao Cheng meets yingyou, who is a member of Aoping''s family. He looks very popular“ Because I heard that I found my mother''s remains, so I came to have a look. " Mr. Bentang explained“ Mother''s legacy? "“ Yes, that''s it. It had been hanging in the closet of the maid''s room before... "Gao Cheng looked down at a black leather bag and scattered photos on the table. There is a picture of yingyou Bentang and a maid in her childhood. The maid also has a pair of cat''s eyes“ I found it, "explained the fat maid." after I showed it to my wife, I found out that it was the maid who used to work here, so I found the child... "The horse faced housekeeper with glasses came over and said," today is the first anniversary of master Xunwei''s death. My wife said that it must be master Xunwei who showed up... "" er... "The scene was stunned, Bentang yingyou looked at the housekeeper and said, "long time no see. After ten years, the housekeeper is still the same." The housekeeper looked flat: "you should be talking about my brother. I was the housekeeper who took over from my brother in a car accident two years ago."“ Yes, it''s like this... "Bentang yingyou was slightly embarrassed. He quickly found a small book from his wallet and said to Gao Cheng," look, there''s my mother''s and my son''s manual, which says that my blood type is o! So there should be no doubt? "“ It''s hard to say. After all, it''s not sure that your sister gave you a blood transfusion... "Gao Cheng took over the manual to check yingyou''s birth information. At the same time, Aoping jiaozang came out, and yingyou said:" Uncle jiaozang! "“ It''s yingyou, "aopingjiaozang said with a rare smile," I haven''t seen it for ten years. I still remember your mother is a very good maid... "Then he turned to Gao Cheng, who was reading the manual:" this is the living room where we watched the video at that time. It was a video taken by Yongzi and I when we were traveling abroad last year. After five hours, we went to the toilet, No one has ever left here... "" is this the toilet? " Gao Cheng opens the toilet door next to the living room and finds that it''s quite a small toilet. The wash basin and toilet take up most of the space. There''s only one door to the living room. Besides, there''s a small window. It''s hard for children to get through, not to mention adults. There is no secret door to sneak out of the living room... If the alibi can''t be fake, it should be how to control the time of death of the victim on the other side. There have been many such cases. Drowning directly reminds people of several time techniques in the past.
