Kudo Shinichi said so, but he didn't think so in his heart.

As class was about to end, he stared at Sayuri Matsumoto as he approached Ran's side, his low voice a little hoarse.

"Xiaolan, I remember that this Matsumoto-sensei's father worked at the Metropolitan Police Department, right......"

Xiaolan looked at him and nodded, "Yes, Matsumoto-sensei's father is my father's boss back then, Matsumoto Kiyocho." What does this do, you ask? ”

Shinichi's eyes rolled and he pulled out a smile. "I would like to visit Matsumoto's house and learn about Officer Matsuda's case."

"Huh? Don't ......," she slapped her face weakly.

Even if she said so, after a crisp bell in the afternoon, Xiaolan was still dragged away by Shinichi.

"Excuse me." When they entered the door, the two of them were hunched over, very timid.

"Don't be so polite...... "Sayuri snickered as she covered her mouth." Come on in, Mori-san, Kudo-san. ”

At this time, it was time for Matsumoto Kiyoshi to investigate the case in his study at home. As if he heard the sound of an outsider coming, he walked slowly to the entrance in his slippers. "Any guests, Sayuri?"

"Yes, it's the students in the school. The two of them wanted to ask their father about Officer Matsuda's case. It seems that the two of them should be mystery fans. ”

Xiaolan didn't want to be in the same category as the guy next to her, so she moved her position slightly.

At this time, Kudo can really only be regarded as a reasoning enthusiast, just an ordinary junior high school student without any title or prestige.

He touched the back of his head and smiled embarrassedly.

"It's okay, one more person, one more head anyway." As he spoke, Kiyocho Matsumoto made an inviting gesture.

The study was very dark, and Matsumoto didn't turn on the main light, but just talked eloquently through a few faint secondary lights, and Xiaolan got goosebumps all over her body when she listened.

At this time, Kudo lifted his chin with a solemn expression. "I see...... So, who has Officer Matsuda offended before? ”

Matsumoto shook his head, "Although he speaks very incoherently, and sometimes loses his temper easily. But his character is really good, and I'm also very optimistic about him. The reason why he asked me to transfer him from the explosive disposal squad to the search class was because he didn't want anyone to catch the murderer himself like his colleague who died in the explosion a few years ago. ”

Xiaolan still had palpitations in her heart, and flickered: "Maybe Officer Matsuda will be remembered for offending someone by his words." I remember the report saying that the killer was a man. Either he offended anyone, or the man was doing something illegal and was seen by Officer Matsuda. ”

But Kudo doesn't think so.

Matsuda Jinhei disappeared between noon and night, and until then had been talking about the two gem robbers. If it was a prisoner who met by chance, it would not have been possible to disappear for so long, and he kept communicating with other police officers by text message.

Maybe for some reason he can't use a voice phone, or maybe he can't communicate on the phone at all.

Because the people in the forensic department also said that the time of death could not be precise, maybe he would have been killed at noon.

If so, why would the prisoners help the police locate the two bombs and help them catch the bombers?

His thinking cycles from establishment to self-rejectation.

Looking at Shinichi and Matsumoto Kiyocho who were deep in thought, Xiaolan muttered softly: "There have really been too many things that have happened recently, the prisoner of the gem robbery has not been found, and another murderer has come out." ”

As soon as these words were spoken, a new inspiration flashed to him.

Will there be any connection between two mysterious criminals who also have no clues? Could it be the same person?

His hand grasped the edge of the desk in front of him, his expression urgent. "So, may I ask if the person in charge of the gem robbery case is Officer Matsuda Jinpei?"

Matsumoto Kiyoshi looked at him with a hesitant look in his eyes, and then nodded after a while. "That's right, because the case happened on New Year's Day, and the only police officers on duty that day were Matsuda Jinhei and Miwako Sato. Among them, Matsuda is almost entirely responsible. ”
