Chapter 1598: The mystery of the old couple

　　 October 14, Friday, afternoon.
　　 After school, Conan went straight to the hut near the Maori detective office and found that there was already a master, Udoku.
　　 At this time, Genta, Ayumi, and Mitsuhiko appeared.
　　 Genta said, "It's a strange name."
　　 Mitsuhiko said, "That's Udohisa."
　　 Ayumi said, "If the name tag has been hung up, it means it has moved in."
　　 Conan asked helplessly: "What are you doing here?"
　　 Bumei smiled and said, "Conan, you ran away alone, Xiao Ai said that you would come over and take a look curiously.
　　 Mitsuhiko said: "No matter how small it is, as long as there is a question, it must be thoroughly investigated. This is the basis of detective science."
　　 Yuan was too confused and asked, "But, are there any questions here?"
　　 At this time, the door of the small building opened, and an old woman about seventy years old came out, tall, not fat or thin, with a kind smile.
　　 "Ah, how are you."
"Hello."
　　 The old woman smiled and said, "You kids live near here, right? We just moved here today. If you don't mind, please come in and sit down and tell me something nearby."
　　 Bumei smiled and said, "Okay, grandma."
　　 Mitsuhiko smiled and said, "The things about Mihuacho are covered by us."
　　 Yuantai smiled and said, "I know where the eel rice is cheap and delicious."
　　 The old woman put her palms together and smiled: "It's really good."
　　 At this time, the old man came out carrying a shoulder bag and sat down in the hallway to change his shoes.
　　 The shoulder bag is about forty centimeters long and thirty centimeters wide. Perhaps the backpack has some weight. The old man stood up on the floor with his hands, but Conan found that the old woman seemed very dissatisfied.
　　 "Then, I'm out."
"have a safe journey."
　　 sent away her husband, the old woman invited Conan four people into the house, and served drinks and snacks in the restaurant, but there was no furniture in the house, everyone was sitting on blankets.
　　 The old woman smiled and said, "I'm sorry, the furniture has not been delivered yet."
　　 Conan asked: "Grandma, do you live here with the old grandfather?"
　　 "Yes," the old woman answered.
　　 Conan asked, "Aren't you afraid of the steep stairs?"
　　 "It's okay, isn't there a handrail?" The old woman smiled, "Actually, I always wanted to live in this house when I was young."
　　 Ayumi smiled and said, "Well, I think I can understand this feeling."
　　 Motota swallowed the snack in her mouth, "My grandma often said, "It would be nice if I could live in a high-rise apartment once."
　　 The old woman smiled and said, "Besides, this is very close to where my only child lives."
　　 Mitsuhiko smiled and said, "That's it, but you still have to be more careful."
　　 The old woman praised: "Thank you, you are so considerate."
　　 Yuan boasted too much: "Anyway, if you have anything, grandma, even if you come to our juvenile detective team, we can solve everything."
　　 "Really? If there is a chance," the old woman smiled, and then turned to the surrounding situation. ...
　　 After Yuanta finished cleaning the battlefield, he stuffed the last snack. It was already evening, and the four of Conan thanked the old woman for their hospitality and left.
　　 Yuantai and the others think that the old woman is fine, but Conan still has some concerns, just can't figure it out for a while. ...
　　 In the evening, Maori.
　　 The front page of the Evening News published news about the establishment of a bill related to postal privatization. ...
　　 Conan came home and was in time for dinner, so he continued to think about things while eating. His absent-minded appearance made Maori annoyed, and he planted mushrooms directly on Conan's head.
　　 Conan woke up from the pain, and hurriedly concentrated on eating. He heard from Lan and Maori that one of them was going to participate in the club activities and the other was going to play mahjong. Tomorrow and the day after tomorrow, he was the only one to watch the house.
　　 Conan answered simply, but thought in his heart, this is a good opportunity to observe the couple. ...
　　 October 15th, Saturday.
　　 When Lan and Maori left, Conan went to squat outside the small building. In the morning, the old woman went out and Conan followed, but they went shopping for groceries.
　　 Conan followed all the way, and while he was half-dead, he found a specious suspicious point. This old woman was really energetic when she went shopping, and she didn't belong at all. This, well, walk with her.
　　 These housewives who buy groceries are very energetic. Even those who seem to be 80-year-olds are full of bargains with the merchants, and they can say nothing to the merchants. ...
　　 At noon, Conan went to buy a fast food and came back to stay on, while imagining the old woman and his wife eating a big meal, while eating tasteless fast food in his hands. ...
　　 In the afternoon, the old gentleman went out. Conan felt refreshed and hurriedly followed, but when he got to the intersection, he hired a taxi.
　　 Conan was heartbroken by the fare, but had to hire a taxi to keep up.
　　 This person actually followed Yokohama Chinatown. After the driver stopped, he looked at Conan suspiciously, wondering if he could pay the fare.
　　 Conan looked at the fare, silently handed over the bank card, swiping the card for overdraft.
Since the 　　 Boy Detective Group became a backup member of Mei Daizi’s Invincible Beauty Girls Club, each person has received a bank card, and the card will receive a monthly subsidy of 10,000 yen from the Invincible Beauty Girls Club.
　　 This card of the Detective Boys has a certain degree of discount when purchasing goods or services of the Good Mood Foundation, but it depends on the item.
　　The overdraft can only be used once in an emergency, and the upper limit is 120,000 yen issued a year. The overdraft cannot be overdrawn again until the debt is paid off, so as to avoid misuse by the cardholder.
　　 The taxi Conan hired this time was not from the Good Mood Consortium, so full payment was required. This made Conan regret that he just didn't use his cell phone to make a call or book one on the service website through the Internet.
　　 Swiping the card and getting off the car, Conan continued to follow the old man, followed up the warehouse of a Chinese antique shop from the back door, and listened to the old man and a Chinese old man for help.
　　 Conan couldn't help but approached, but he accidentally touched the bead curtain on the cabinet and made a noise.
"Who is there?"
　　 Seeing that the old Chinese man threw the big knife beside him as a throwing knife, Conan hurriedly avoided, and then rolled away.
　　 Out of the warehouse and on the crowded street, Conan breathed a sigh of relief, then thought about it, and decided to do it today.
　　 Conan looked at the road signs and went to the Chinatown station, ready to take the tram home.
However, after reading the route map and the connecting route, calculating the ticket price, and then touching his pocket, Conan was a little dumbfounded. The transportation card was gone, the cash was not enough for the whole journey, and the bank card was no longer able to overdraft, so he could not get from the ATM. Withdraw money as an emergency.
　　 First take the Minato Mirai Line tram to Yokohama Station. This is a cash payment. You can also use the transportation card of the Good Mood Foundation, but there is no discount.
Then transfer to the Toshin Railway Main Line to Gosenji Station in Takanawa, Minato-ku, Tokyo, and then transfer to the Mihua Underground Loop Line back to Mihua Plaza Station. You can use the transportation card or bank of the Good Mood Foundation Card, there are discounts.
　　Of course, you can also choose other lines at Yokohama Station, get off at a station on the Toto Loop Line, and transfer to the Toto Loop Line to Mihua Station, but the full price is normal.
　　At Conan's age, I could have gone to the police and asked the police to help send them home, but that was really shameful.
　　 As a last resort, Conan called a special car, Dr. Aka, let Dr. Aka go to Yokohama Station.
　　 Conan still has the money to go to Yokohama Station by car. ...
　　 Outside Yokohama Station.
　　 In Dr. Aka’s laughter, Conan slammed into the car with a black face.
　　 "I said what are you doing, come here?"
　　 "I'm following someone."
　　 "No, are you still entangled with the couple?" Dr. A Li smiled, "I really said it to Xiao Ai, she guessed that you followed them and couldn't go home."
　　 "Really." Conan blushed, "Drive carefully."
　　 Dr. Aka asked curiously: "Now, is there any result of the investigation?"
　　 Conan was a little discouraged, "No progress." Then he asked, "By the way, when the old man wants to stand up, does he often have to support the ground with his hands?"
　　 Dr. Ari smiled and said, "That's right, I actually have it too, in order to protect the knee joint."
　　 "Ha, you are fat." Conan said amused, and then asked, "But, grandma frowns, do you think this is normal?"
"Well, it should be because I usually tell him to stand up directly when standing, especially when he is in front of people. I don't like him to be like an old man." Dr. A Li laughed at himself, "I also often get Yuan Yuan. Too accusing, like an old man, like an old man."
　　 "That's it." Conan didn't say any more, but he still couldn't let go of it. ...
　　 In the evening, Maori house, balcony.
　　 When Conan was collecting clothes, he accidentally found a little reflection, from the direction of the small building.
　　 Conan was startled and thought of the attic of the small building, where he could see the detective office.
　　 Conan figured out why he had been so worried about the couple because that was where the detective agency could be observed, but the couple inside were not suitable for that kind of house.
　　 Although there are various reasons, I like it, I moved away from the place where my son lives, but there is no need to choose that one. You can find more suitable houses for the elderly around here.
　　 Conan found the binoculars, went to the rooftop to look around, and found that there was a camera on a tripod with a telephoto lens, now facing the direction of the Maori detective office. ...
　　 Dr. Aka’s house.
　　 Conan ran to give Huihara the phone, let her look at the photo above, and see if the couple might be the organizer.
　　 "Isn't it?" Dr. Aka was taken aback, "How come you suspect that they are from that organization?"
　　 Conan did not say that they were taking pictures, only that Hui Yuan looked at the pictures on the phone.
　　 Huihara looked at it, "I haven't seen such an old man."
　　 Conan asked: "Is it a fake~EbookFREE.me~ It's not an old man, but a young man, that house is suitable for young people."
　　 "I don't know, but it's not impossible." Huihara asked seriously, "Think about it, what have you done recently? Can it arouse the organization's suspicion?"
　　 "No, I have thought about it." Conan said with his chin in distress, "If you want to talk about the big thing, it is the previous loss of money, but that was not exposed at all."
　　 Dr. Ari guessed in surprise: "By the way, could it be discovered when the funds were transferred? Your parents gave you the money, didn't it, Conan?"
　　 Conan said: "No, it was handled by the Good Mood Foundation, and this flaw will not be left."
　　 "Then quickly think about what went wrong." Huihara said nervously. He couldn't stand the magazine anymore and threw it directly on the table.
　　 Looking at the magazine, Conan was taken aback, and then asked, "What's the date today?"
　　 Dr. Aka asked: "October 15th, Saturday, what happened?"
　　 "Ha... so it is."
　　 Conan laughed, but then turned into a bitter face, and then pulled out a smirk.
　　Dr. Akasa and Haihara looked at each other. What's wrong?
　　 "Doctor, please do me a favor." Conan pulled Dr. Aka and bit his ear.
　　Huihara raised his triangular eyes in dissatisfaction, "Hey, don't sell it!"
　　 "Hey, I'll know at night anyway." Conan turned around and slid away.
　　 Haibara looked at Dr. Aka, and Dr. Aka said helplessly: "He asked me to wear black clothes to the detective office at night."
　　 "Damn it." Hui Yuan tickles his teeth. Looking at the magazine on the table, he couldn't see what inspired Conan. ...
