Let You Simulate A Crime, Not Let You Commit A Perfect Crime

The riddle was already in front of them, but Kong Wangshan and Zhu Liang had no clue for a while, and the two poisoning methods in this case were beyond their understanding.

They decided to investigate separately, investigate a poisoning case alone, wait for a while, and then exchange information to investigate, so that they may rely on the difference in thinking between the two to find a breakthrough.

Zhu Liang investigated the first homicide case, he looked at the surveillance again, and interrogated everyone in the villa separately, there were a total of seven people in the villa, in addition to the deceased Xiaokai and Ah Fang, there were cooks, nannies, and three company employees: female secretary, supervisor, manager.

Through the door monitoring, it can be found that no one left in the middle, then it is basically certain that the murderer is still in the villa, then the murderer should be among the five people alive.

And the poison is determined on one of the cakes, which should be poisoned after the cake is ready, that is, the poisoning time is during the time when the cake is made and pushed up.

Zhu Liang first asked the chef, "What time do you make the cake?"

Chef: "9:30."

Zhu Liang: "So precise?"

Chef: "Because I look at the time, the cake wants to be made well, all steps must be controlled, and a minute difference in time will affect the softness and color."

Zhu Liang: "What is the cake baked with?"

Chef: "Microwave."

Zhu Liang: "After the microwave oven finished making the cake, what else did you do?"

Chef: "Nothing was done."

Zhu Liang: "After the cake is ready, where to put it?"

Cook: "On the table outside the kitchen, I told the nanny to push it to the living room for a while, I covered it with a lid, but anyone can open it."

Zhu Liang checked the temperature and smell of the microwave oven, found no obvious loopholes, there was still a little residual temperature but not high, and there was a strong cake smell.

It is also reasonable to put the cake on the table after it is ready, after all, there are many things in the kitchen, and the chef has to do something else, and the temperature is too high just after it is made, and it will be hot if someone takes it immediately.

Zhu Liang then asked the nanny: "What time do you go to get the cake ||?"

The nanny said: "I was drying clothes in the yard, and after the chef called me to explain it, I immediately went to the dining room, cut the cake, and when it was not too hot, I pushed it directly to the living room."

Zhu Liang: "After the chef explained, you immediately went to the restaurant?"

Nanny: "Yes, there was no delay for a moment, because Xiaokai said that he was very hungry and was a little anxious." It's just too hot, I cut it and waited for a while.

Zhu Liang: "Have you been keeping this process, has anyone else touched the cake?"

The nanny shook her head: "I haven't been guarding, I went into the kitchen and asked the chef, if there is anything else, if there is, I will send it together, it should be this time, someone has touched the cake."

Zhu Liang was stunned: "Are you so sure that someone has touched the cake?"

The nanny said: "The cake was originally a whole piece of ring, I cut it and left it as it was, but after I came out of the kitchen, the cake was arranged in different shapes, that must have been touched by someone, I didn't think much about it at the time, anyway, this shape is quite neat and beautiful."

Zhu Liang's heart moved, this is a very important information.

If the nanny did not lie, then the murderer should be between the secretary, supervisor, and manager, otherwise, it is too strange to deliberately place the cake, if the nanny lied, then the murderer is likely to be a nanny, otherwise, why deliberately tell this lie?

The suspicion of the chef has been reduced a lot.

Zhu Liang asked again: "How long did it take for you to receive a call from the chef in the yard, walk to the restaurant, cut the cake, and go into the kitchen to talk to the chef?"

Nanny: "Not sure."

Zhu Liang asked, "At least more than a minute, right?"

Nanny: "That's for sure."

Zhu Liang: "Two minutes?"

The babysitter said, "That's not certain."

Zhu Liang checked the call time between the chef and the nanny, and it was indeed 9:30.

Through the monitoring of the living room, it can be seen that the nanny pushed the cake to the living room at 9:34, so the poisoning time can basically be determined "within these four minutes."

And the time the nanny entered the kitchen, at least 9:31, she said, after coming out of the kitchen, the cake was arranged in different shapes, and if the nanny did not lie, the murderer was among the other three, which could have further narrowed the poisoning time to between 9:31 and 9:34.

Zhu Liang further investigated precisely, between 9:30 and 9:34, where the secretary, supervisor, and manager were, and found that they were all chatting on the balcony at first.

But after a while, the secretary went to the bathroom, the supervisor went out to smoke a cigarette in the yard at the door, the manager stayed on the balcony, the three were separated, none of them could corroborate each other, the bathroom and the balcony were not monitored, that is, neither the secretary nor the manager had an alibi at all.

There is monitoring at the door, you can see that the supervisor is about 9:31:10 seconds, he opened the door and went out, until 9:34, he has been outside the door, if it is his crime, there is only 10 seconds, the time is too hasty, poison and then place the cake and run out, it is unlikely to be happy.

Zhu Liang investigated the trash can between the restaurant and the balcony, and sure enough, he found a small bag that detected cyanide, which should be a poison package. Traces on the poison packet were detected and no fingerprints or DNA were found. The murderer threw the poison packet here apparently on purpose, as long as the poison will pass through this position, whether it is a secretary, supervisor, manager, nanny or cook, it is possible.

Zhu Liang observed the balcony, bathroom, and doorway, and found that standing on the balcony, you can see the restaurant, whether from the bathroom or the door to the restaurant.

So Zhu Liang asked the manager who had been staying on the balcony: "." You stayed on the balcony, did you notice who was walking towards the restaurant or heard the sound of walking towards the restaurant?"

The manager shook his head: "I was playing with my phone facing out the window, and I didn't see or hear."

This explanation is reasonable, there is not much problem, now when people are alone, they generally play with mobile phones, if they don't pay attention, it's normal to not see or hear. But it is undeniable that the manager on the balcony is suspected to be older than the other two.

Zhu Liang still wanted to investigate further, but he couldn't find a breakthrough, the number of murderers and the time frame had shrunk to a small extent, but it was impossible to accurately lock.

The most uncomfortable thing is that it is impossible to screen it in combination with the last step of the modus operandi, after all, I can't understand how the murderer let Xiaokai take the initiative to choose the only poisonous cake.
