Three people and one ghost solved 43 mysterious cases.

Then, we need to tie the glass bottle to the homing pigeon's feet. Since it is tied to the feet, how can the glass bottle fall automatically after it reaches here?

Even if this is a well-trained pigeon that can bite the string tied to the glass bottle by itself, then the pigeon cannot bite the string in the air. It must land. Since it has landed, how can the glass bottle break?

Open Lenovo again, there may be some kind of animal audio jammer in the house. The sound of the jammer is inaudible, but it will make the pigeons instantly furious.

The furious pigeon pecked the glass bottle directly with its sharp beak. This time it was okay. The powder came into contact with the air and caused a fire.

But the most crucial point.

If Sui Yuan was the murderer, he did not know that Pan Zhenni had been killed by Wu Jiang.

He believed that at 10:30, Jenny Pan was still alive.

Then Pan Zhenni will definitely be able to detect the source of the fire that was just caused, and will run away if she detects it.

Yuan Fugui interrupted Xu Wenshan’s speculation and said, “Pan Jenny had taken hallucinogenic drugs before her death. Sui Yuan knew that Pan Jenny had a habit of abusing drugs for a long time, so he knew that at that time, Pan Jenny was most likely unconscious. Clear state."

"Yes. I agree with this. However," Xu Wenshan said, "Pan Jenny only took hallucinogenic drugs. How can Sui Yuan guarantee that Pan Jenny will definitely die in the fire?"

Yuan Fugui thought in his heart, it was indeed so.

If Sui Yuan goes to great lengths to do this, Pan Jenny will definitely die in the fire, but all inferences are risky——

It had to be an open window, an extremely intelligent homing pigeon, or some other bird, and Jenny had to be completely unconscious.

These three elements must be met simultaneously.

If Pan Zhenni closed the window after Sui Yuan left;

Suppose the chemical in the glass bottle brought by the homing pigeon comes into contact with a moist spot on the ground and does not cause a fire;

If Jenny Pan is only slightly hallucinated and still conscious, she still has the ability to move——

After all, she abused drugs to stimulate inspiration and write through the hallucinations she produced. It was impossible for her to take so much that she would become completely comatose.

As long as there is a deviation, it will not cause a fire. It is impossible for Sui Yuan to use such a carefully thought-out plan to gamble on a "perfect accident" with only a [-]% success rate.

"It's impossible," Yuan Fugui sighed, and the inference formed and collapsed.

.

Xu Wenshan said, "This is what investigation is like. The 100 kinds of reasoning in each case are all aimed at the only truth."

He added, "Inspector Yuan, you are already great."

"Don't say useless things." Yuan Fugui quickly cheered up, "Since you are here too, let's find the truth together."

"Agreed." Xu Wenshan took out a cigarette from his pocket, put it to his nose and inhaled.

The two of them walked into the bathroom that was separated from the study room again.

The damp bathroom burned most violently and was the source of the fire.

Xu Wenshan shined a flashlight on the top of the bathroom, only a hollow shelf was left on the top.

Xu Wenshan said, "The fire probably started from the roof. The fire burned all the wooden plywood on the roof, exposing the skeleton. The fire spread along the wooden plywood and outside the bathroom. Sparks fell on the carpet, making the second floor Burned fast.”

"Yes, that's how fire is caused, but why exactly does it ignite?"

Xu Wenshan said, "Let's not think about this problem first. We should assume that we are the murderer. The first step for the murderer is not to set a fire, but to make Pan Jenny completely unconscious."

When reasoning reaches a dead end, sometimes it may be helpful to look at it from another angle.

"Then let's start. Let's each imagine that we are the murderers." Yuan Fugui closed his eyes and thought:

If I were the murderer, how could I make Pan Jenny unconscious before the fire?

I was not present at the scene, how did I know that Jenny Pan would be unconscious?

There seemed to be countless murderers in Yuan Fugui's mind, trying to plan crimes in countless ways.

Then I need to know Jenny Pan well enough to know what Jenny Pan will do after I leave.

What will she do? Write a book, abuse psychedelics, what else must you do?

It was night when the crime occurred. What would a woman do at night?

bath!

Yuan Fugui opened his eyes and looked at the burned, or rather exploded, remains of the water heater in the bathroom.

Yes, Jenny Pan definitely knows how to take a bath.

There were burnt black rose petals in the bathtub, indicating that the bathroom was running water at that time.

If Jenny Pan wants to take a bath and sit in the bathtub, this is the best opportunity.

Hot water, how hot water made Pan Zhenni unconscious.

Heater? Conduct electricity!

Yuan Fugui made a bold guess:

What if Sui Yuan had tampered with the water heater early on and installed a conductive device in the water heater.

That's why he had to come here at nine o'clock in the evening. On the surface, he was bringing a double-skinned milk, but in fact, he was filling the bathtub with water and making sure that Jenny Pan had to take a bath in the bathtub.

He turned on the conductive device and left.

He judged that Jenny Pan would take a bath within half an hour. When Pan Jenny was soaking in the bathtub, the rose petals——

Yuan Fugui walked to the burned bathtub and sat down, leaning back in the bathtub.

Now, she fantasized that she was Jenny Pan, who would be sitting in the bathtub, just as the killer surmised.

She enjoys soaking in the bathtub, which stimulates inspiration. She will soak for a long time, but the water temperature will drop. If it drops, hot water is needed.

So--

Yuan Fugui closed his eyes and reached out to touch the faucet that was burned black...

Xu Wenshan bit his unsmoked cigarette and looked at Yuan Fugui in the bathtub.

He looked at the woman who was obsessed with reasoning. At that moment, Xu Wenshan suddenly felt a sense of déjà vu. The Yuan Fugui in front of him looked too much like "that person".

Very similar to Yao Ruolan.

22 years ago, Xu Wenshan was still a young police detective and his best partner was Yao Ruolan, a female doctor of psychology.

They faced a series of scheming murder cases and returned to the scene of the crime again and again.

Yao Ruolan is like this, behaving strangely, changing the roles of the murderer and the deceased, immersed in the world of reasoning.

Xu Wenshan stared blankly at Yuan Fugui, missing Yao Ruolan.

.

"She will be electrocuted to death." Yuan Fugui opened his eyes and said suddenly.

"Electrocuted to death?" Xu Wenshan came to his senses.

right! Electrocuted. Yuan Fugui suddenly realized.

If Pan Zhenni had not been killed by Wu Jiang, she would have been soaked in the bathtub. When the water cooled down, Jenny Pan opened the faucet, and at this time the conductive device in the water heater started to operate.

Electricity is transmitted through the water in the faucet, and when the faucet is turned on, the electricity is connected to the water in the bathtub.

Pan Zhenni will be "shocked" by the instantaneous electric shock and fall into coma on the spot.

"So, Sui Yuan used a water heater to electrocute Pan Zhenni. Even if the electric shock didn't kill Pan Zhenni, Pan Zhenni would definitely be in a coma."

Yuan Fugui stood up from the bathtub and touched the water heater hanging on the roof. It couldn't be called a water heater. It was really blown to pieces and only a few fragments were left.

Yuan Fugui touched the fragments and thought:

Even if there is a fire, the damp bathroom and water heater will not be damaged so badly.

The only explanation is that the water heater is not only equipped with a conductive device, but also a detonator.

At a certain time, the murderer calculated that Pan Zhenni would be unconscious in the bathtub, and the detonator in the water heater detonated automatically.

The explosion caused an uncontrolled fire in the wooden partitions of the roof.

This is the "unexpected" probability of success.

As the water heater continues to burn, and with the raging fire, the "murderer" can use a fire to burn the unconscious Pan Zhenni to death.

When Pan Zhenni was burned beyond recognition, it would be difficult for the police to determine the exact cause of Pan Zhenni's death.

At the same time, due to the fire, the water heater, the murder weapon left at the crime scene, was completely burned and all evidence was destroyed.

But the murderer didn't expect that Wu Jiang also wanted to murder Pan Jenny that night.

Wu Jiang killed Pan Zhenni at the entrance of the first floor at about 45:[-] and then escaped.

Unbeknownst to the murderer, the detonating device of the water heater detonated at [-]:[-], causing a fire.

"This is the truth about Pan Jenny's murder case. Two murderers, two murderers who didn't know each other, wanted to kill her." Yuan Fugui shook his head helplessly, "They both formulated a perfect murder method at the same time. Two perfect murder methods. Murder, murder of the same person, Jenny Pan is really bound to die.”
