After listening to what Aizen said, Yokomizo Sango held up his chin and looked at the scene. He proofread Aizen's reasoning and nodded, "At first glance, the first impression of Professor Hirota's death is indeed an accident, but the dropping of the phone is indeed abnormal. Mr. Aizen, your reasoning is reasonable. You are worthy of being the disciple of the famous detective Mouri."
"Who was it? Who killed my husband? Who was it?"
Toshiko Hirota questioned Yokomizo Sango. She didn't think her husband would commit suicide. He must have been murdered.
"Please calm down, Mrs. Hirota!"
Yokomizo Sango stopped Toshiko Hirota's excitement and asked, "Mrs. Hirota, besides Mr. Aizen, has anyone else visited your husband tonight?"
Toshiko Hirota said, "I attended the township meeting with the lady next door today. I went out at 8 o'clock and came back at 11 o'clock. When the lady next door and I were out, a man came here. My husband said he was his student, and his surname was Hosoya."
Yokomizo Sango said to a policeman at the door, "Very good, you go and find this Mr. Hosoya who came to visit me."
"Yes!"
The policeman responded, saluted, and walked away.
Yokomizo Sango continued to ask, "Mrs. Hirota, besides this, do you know anyone else who has been here?"
Toshiko Hirota shook her head helplessly and said, "I only remember that before we left, my husband told me that Mr. Aizen would be coming tonight, and there would be two or three more people like this."
Hearing this, Yokomizo Sango held his chin and said, "In that case, we can only check all of Professor Hirota's students one by one."
"Oh my!"
Conan lay on the floor, looking at the phone and said, "It's strange, this phone seems to be glowing."
When Yokomizo Sango looked at it, Conan said, "This seems to be called a telephone answering machine. Maybe we can find something by looking at the message."
Aizen squatted down and whispered to Haibara Ai beside him, "Our famous detective plays the role of a child very well, right?"
Haibara Ai nodded, with a slight smile on her lips, and said, "It seems that he is enjoying it."
"That's true!"
Yokomizo Sango nodded after hearing this, walked to the side of the phone, took off the book on it, and then opened the telephone answering machine.
Soon, the message boards were exhausted.
Yokomizo Chango said, "Thirteen messages in total. That seems like quite a lot."
Ten of the thirteen messages were left by a man named Shirakura. Toshiko Hirota learned that he was a student of Masami Hirota. Another was left by a man named Mourioka, a former student of Masami Hirota. Toshiko Hirota had met him before, and two of the messages were from him. The last one introduced himself as an insurance salesman, wanting to introduce his company's new products.
While listening to the recorded calls, Shirakura arrived at the scene. He was the Shirakura who had left ten voicemails.
As they listened to the last recording, Haibara Ai whispered, "It's Vodka! Although his voice was deliberately altered, I could tell it was Vodka's."
"Vodka!"
Conan's body trembled at the words, his mind instantly flashing back to the scene of the transaction at the amusement park. The burly man doing the deal was Vodka. He hadn't expected to hear that name again after all this time.
Aizen said, "Since they're members of that organization, they weren't the ones who killed them. An organization like that wouldn't want their voices heard at the scene, and if they were after the floppy disk, there's no need to set up a secret room here."
Conan nodded in agreement and looked at Shirakura, who was being questioned by Yokomizo Chango. He felt there was something wrong with him. It was impossible for anyone to leave so many voicemails at once, even if Masami Hirota hadn't answered the phone.
"The reason why Vodka left a message on the phone was that he wanted Professor Hirota to relax his guard if he was at home, all for the purpose of completing the mission better."
As she spoke, Haibara Ai chuckled softly and said with amusement, "I think they must be extremely anxious now. If they can't get the disk back, they will be in trouble." She found it interesting and fun to think that Vodka might be in trouble because of this.
Conan smiled upon hearing this and said, "So, Vodka probably hasn't retrieved the disk yet. He might be nearby."
Aizen looked at Haibara Ai and said, "If that Vodka is really around here, I'd like to meet him and see just how powerful the member of the organization you're talking about is."
"You'd better not do anything rash. Vodka is a high-ranking official in the organization. While not the most powerful among the high-ranking officials, he's not to be underestimated. And he's definitely carrying a gun. You'd better not take any risks,"
Haibara Ai said hurriedly. Although Aizen had been somewhat upset by her prank when they first met, she was still grateful to him. After all, Aizen had saved her sister and let them live in his house. Although she didn't express it, she felt grateful to him. Besides, Aizen was her sister's boyfriend. If anything happened to him, her sister would be heartbroken. She didn't want her sister to be sad, so no matter what the reason, she didn't want anything to happen to Aizen.
Aizen smiled and said, "Don't worry, I won't do anything rash. Besides, with you two here, it would be terrible if you were to get involved. I'll see what happens."
"Even if it's just for my sister, don't take any risks."
Haibara Ai breathed a sigh of relief, but still gave her a warning.
Aizen nodded in understanding. Just then, two people appeared at the door. One was Kazuhiro Hosoya, and the other Michio Morioka. The former was the man Toshiko Hirota had met, while the latter had left two recorded phone calls.
Kazuhiro Hosoya had come to ask Masayuki Hirota for help with Nanyo University, as his daughter was applying to Nanyo University. However, he discovered that Masayuki was very drunk, so he gave up and went back.
Michio Morioka had come to play chess with Masayuki Hirota. It was Masayuki who had invited him to play chess, but since they hadn't set a time, Michioka had called twice and even came in person at 9:30. He knocked on the study door, but no one answered, so he decided to go back.
