One lie needs to be explained with more lies, but Kevin can't explain it now.

Bell looked at Lin Yuhan, his face showed a hint of surprise, and he asked puzzledly, "How did you confirm that this Kevin is the murderer?" ”

Lin Yuhan glanced at Kevin, who fell to the ground, and said, "Two aspects. First, I simulated the scene of the crime, the murderer hanged Shi Yulong from behind, and now there are not too many traces of struggle and fighting, so I guess that the murderer killed Shi Yulong by surprise, and the relationship between the two must be very familiar, or they know each other, before killing him, they were talking about something, so Shi Yulong was not prepared at all. So, the only person I can think of is Kevin.

He paused and continued, "Second, I just returned to the scene of the crime. After trying, I found that although the size of the ventilation duct can allow one person to pass through, the inner wall of the pipe is very smooth, and the pipe is high and does not have any attachment points, so it is very difficult to get in with the force, and it must be done by two people. One enters, the other waits inside the pipe, and then pulls him up. So ......"

Lin Yuhan turned his head to look at Alamp: "That accomplice is you!" ”

Elamp's body slammed.

Lin Yuhan analyzed: "You swear that you didn't kill anyone, and I believe you." Because you really didn't kill anyone, but you were an accomplice. After Kevin killed Shi Yulong, you pulled him up from underneath, and this happened to be at this time, I arrived with the first mate and Amy, so you and Kevin fled in such a hurry that you didn't even notice that the rags on your clothes were torn and fell into the pipe, or that you didn't have time to pick them up. I was wondering at the time, because the inside of the pipe was very smooth, how could it tear and tear your clothes, and now that I think about it, it was probably caused by Kevin accidentally stepping on your pants when you two were running away. ”

"Do you have proof?" Alum asked.

"Yes, the evidence is the rope found by Sheriff Bell, on which there must be fingerprints of the two of you!" Lin Yuhan said firmly.

"Detective Lin is really whimsical!" Alamp laughed, "Even fingerprints don't mean anything, I have no motive to kill at all, how could I cooperate with a servant to kill a thief." ”

"You have." Lin Yuhan said, "For that information." That is, the evidence that you accuse Eric, that there is some kind of ulterior deal between you and David. ”

"You talk nonsense!" Alamppu was furious, "That person is obviously my brother Eric, and it was a deal between him and David, and he has nothing to do with me, you!" ”

Elamp's face flushed, and he pointed his finger at Eric and roared.

However, Eric's face was calm and did not show too much expression.

"Don't worry, so let's get to the point and talk about the third case, David's death." Lin Yuhan showed his harmless smile.

When talking about "David's death", Lin Yuhan could clearly find that the expressions of several people in the restaurant were obviously different.

Lin Yuhan looked at the ceiling, pondered, and then said slowly: "Actually, at the beginning, I doubted many of you. For example, Ms. Ina, you appear on David's list; Another example is Ms. Linda, you are also on the visit list, but you all have a characteristic, you have not been to this restaurant; So I changed my mind, looked it up again, and when I got the police list, I found a new problem. Mr. Eric had come for breakfast in the morning, but he was not on David's list; Mr. Conward had come for breakfast and was not on David's list......"

"Wait," Lauris interrupted Lin Yuhan's words and asked puzzled, "Is there anything between the two?" ”

"Absolutely! Look here......" Lin Yuhan, with the help of a police officer, turned the table upside down.

"At the bottom of the table, there's a scotch tape mark!"

"This ...... What does it mean? Lawris asked.

Lin Yuhan explained: "Think about it, how the murderer poisoned David with precision. First of all, it's definitely not food, because food is taken in an indiscriminate way, just like when I ate fried dough sticks and soy milk in the morning, I didn't die. Secondly, it is not possible to take the cutlery, because the cutlery is also picked up in an indiscriminate manner. Unless the murderer followed David one after the other, but this was too obvious. They must want to avoid suspicion and will not meet together, otherwise the two of them will definitely sit at the same table to eat, and at the time of the crime, there was only David at the table. Therefore, the place of poisoning can only be the table. They must have been separated, agreed to meet in some way. So, I thought of that, forcing the choice. ”

Lin Yuhan walked to the scotch tape: "The murderer put the transaction items negotiated with David on the bottom of the dining table with scotch tape, and told David to pick it up, and that one was stained with cyanide. As agreed, David came to this table and got something, and then in the process of eating breakfast, he was poisoned by the murderer. ”

Lawris nodded thoughtfully.

So, let's say the two coincide. The people who met with David before this morning or yesterday may be the murderer, and then we can filter and overlap with the people who came to this restaurant this morning, and we can finally lock the target and find the murderer, but ......" Lin Yuhan sold a pass, "It's ridiculous, when I checked the list of the two, I found that this person does not exist ......"

"Cut~" Conward laughed: "Detective Lin is really able to talk nonsense, analyzed with me for a long time, and told me that this person does not exist, are you here to make us happy?" ”

"Not really." Lin Yuhan showed a mysterious smile, "I mean, this person doesn't exist on the surface, but, in fact, he does!" ”

"Yes?" Conward asked, "That's the lesson, where is he?" ”

"Then let's take a look at the list of both!"

Lin Yuhan listed: "The people who came to this restaurant in the morning were: Amy, Eric, Conward, Bell, and I ......; And the people who have seen David are Lauris, Kevin, Ina, Linda, ......"

"Wait!" Conward interrupted, "I didn't come to this restaurant in the morning! I asked the maid to deliver the food. ”

"Hehe~" Lin Yu laughed coldly, he said, "So I said, this person is hidden, and he cleverly concealed his name, so that he could enter the restaurant unconsciously, that is...... Kevin! ”

Lin Yuhan suddenly amplified his voice and knocked on the man's soul: "You took Conward's breakfast coupon and entered this restaurant!" ”
