"Key?" Yamaguchi repeated Keisuke Chiju's opinion, and immediately felt greatly inspired: there is no doubt that the key sent to Hattori Heiji was assigned later, but the premise of the key was that the person had the key.

And finding the person who sent the letter, even if this person is not the murderer, but also has a certain knowledge of the case, can get a breakthrough in the case, which is also an undoubted thing.

Several people present glanced at each other, and there were a total of five keys to the Osaka villa, which were in the hands of Wakamatsu Kohei, Serika, Ikuro, Yonehara Sakurako, and Satake Yoshimi.

After Wakamatsu Kohei died, his key was kept in Wakamatsu Kohei's hand, and then Wakamatsu Kohei's own key and Wakamatsu Kohei were taken out.

Wakamatsu Ikuro's keys were also found in the room, and Yonehara Sakurako and Satake Yoshimi also took out various keys, at least none of them lost them.

"Please recall carefully, there is no possibility or opportunity for your key to be taken away by someone else and then put it back with one?" Shan Shan Gongwang asked, "If not, it basically means that the sender is among you." ”

"Then the two of us are not suspicious, is that so?" asked Junsheng Fujina, holding up his hand.

"No, it just proves that you are not the sender, and it does not mean that you are not suspected of killing Wakamatsu Ikuro. "Shan County Gongwang corrected.

"What! It's a waste of time, who's going to kill that kind of imp. Junsheng Fujiba pursed his lips disdainfully, obviously not liking the deceased Wakamatsu Ikuro very much.

At this time, a fax came from Nagano, and the investigation report on the burglary and murder case of the Karuizawa villa had been copied several times and given to the prefecture of Konobi.

Gongwang of Yama County deliberately picked up one and handed it to Keisuke Chiju first, and then took one for himself, and put the rest on the table for interested police officers to take it at will, and he didn't even care if Uncle Maori took a copy.

The special preferential treatment of Qingzhu Qianshou naturally makes people blush, but they are not qualified to talk too much, you are powerful, you can also go and solve the case! But all kinds of eyes full of resentment and meaning fell on the back, making Qingzhu Qianshou somewhat uncomfortable.

"Hmm...... It's similar to what I said before, Keisuke, do you think there's anything wrong?" Shan County Gongwang finished reading the information in his hand, feeling that he had nothing to gain, and turned his head to ask Keisuke Chiju behind him.

The description on the data is similar to the memories of the previous people, but the focus is different, and finally because the traces of invasion were found in the villa, it was determined that the robbers committed the crime.

Keisuke Chiju looked at it more slowly, and it was only to turn to the three-quarters position, but Wen Yan still said: "It is written that Miss Yonehara Sakurako has always insisted that she saw the 's' at that time, but later it was judged that she was wrong, and even now, Miss Yonehara Sakurako still insists that she is not mistaken, is there an 's' there?"

"Yes, the letter 's' accurately said that there should be other characters under the palm of the master's hand, but it was blocked by the master's right hand, so only the 's' was seen. Yonehara Sakurako replied firmly.

"That's the last words before he died?" Yama Prefecture Gongwang thought that he had kept up with Keisuke Chiju's brain circuit, and then began to analyze: "But the names of Mrs. Wakamatsu, Miss Satake, Miss Yonehara, and Mr. Fujina, Mr. Shiina all start with S! The only person who doesn't start with S......" Yama Prefecture Gong looked at the body of Wakamatsu Ikuro who was undergoing an autopsy, and the only person who didn't start with S was lying there.

“son。 Keisuke Chiju said.

"What?" Shan Shan Gongwang did not react.

Keisuke Chiju explained, "I mean Wakamatsu Ikuro is also possible, like son in English. ”

"That ......"

"The key remains the purpose of the sender. Keisuke Chiju went on to explain, "Since Miss Yonehara insists that the 's' exists, it means that the president's killer used some means to cover up this sentence. ”

"Hey, do you mean that Ikuro and I are murderers?" interrupted Wakamatsu, her tone very dissatisfied.

"No, it's just an example, and if you're confident that you're definitely not the murderer, understand that the killer did the feat without you noticing. Keisuke Chiju said a little arrogantly.

"And the person who sent the letter to Mr. Hattori and the person who pretended to scare Miss Toyama obviously knew about this technique, which almost indicated his or her identity. Wakamatsu Celery stopped talking, and Keisuke Chiju continued.

"Oh, how do you mean that?"

"Performing this technique in front of the detective once shows that he is willing to let the detective understand this technique, which is definitely not the position of the murderer of Mr. Wakamatsu Kohei. Keisuke Chiju held out a finger.

"If you want the detective to know about this method, you want the detective to find the murderer of Kohei Wakamatsu, which not only makes this person's position clear, but also brings new questions. Keisuke Chiju held out his second finger.

"Why didn't he choose to report this method to the police himself and hope for the detective?" Keisuke Chiju stretched out a third finger: "This means that letting the murderer be punished by the law is not the best choice in his mind, so after Miss Toyama, who went to the villa instead of Mr. Hattori, failed to find this method, he was relieved to choose the best choice he wanted." ”

"Do it yourself and take revenge on the murderer!" Speaking of which, Shan County Gongwang finally came up with an understanding that made it easy for everyone to understand the meaning.

"The police department is shrewd. Keisuke Chiju slapped a super sycophant, and snapped his fingers by the way: "So, if the murderer of Wakamatsu Kohei is Wakamatsu Ikuro, then it all makes sense." ”

"Speaking of which, a few days before the master was killed, I saw the master and the young master arguing together. The old man angrily tugged at the young master's collar and said loudly, "It's not you who embezzled the company's funds!" Yonehara Sakurako remembered something and asked.

"Oh...... That's it. Wakamatsu Qinxiang took over: "That incident later found out that I just made a mistake in the accounts, and I was scolded by my husband for a long time." ”

"I see...... "Sakurako Yonehara bowed her head.

Satake glanced at Wakamatsu Celery, and a strange light flashed in his eyes.

Keisuke Chiju began to observe everyone's expressions when he began to analyze, and Satake naturally couldn't hide these changes from him. There was also a light flashing in the eyes of Keisuke Chiju.

"That...... Can I ask one thing?" asked as the atmosphere immediately stiffened, and Fujiba raised his hand.
