Chapter 17 Confusion and Illusion (2)
Noah found again that the bed was wet, the water kept dripping down, and the floor was also wet.He thought that the exploding glass bottle must be full of water.However, water will not explode!

Noah called in a guard who was on the night shift with Hewitt for questioning.The guard said that around 9 o'clock, Aiken, who was off work, invited him out for supper, but Aiken went out once in the middle.

Aiken is a researcher in the research institute who studies liquid nitroglycerin freezing technology. Noah learned that he called the guards out, and immediately felt that the explosion was related to Aiken, because Aiken and Hewitt were rivals in love.This explosion can only be done by people with a technical background like Aiken.

So, how did Aiken create the explosion?
Aiken dealt with his rival in this way: he came to the bedside while Hewitt was asleep, put dry ice in a jar, and carefully placed an open bottle filled with alcohol and a bottle filled with alcohol upright. A sealed glass bottle of water, put the jar by Hewitt's side, and leave quickly.Hewitt knocked over the big mouth bottle in his sleep, dry ice and alcohol mixed together, the temperature can drop to minus 80 ℃, the water in the sealed glass bottle also freezes, and its volume expands rapidly, making When a sealed glass bottle explodes, fragments of the jar, together with fragments of the jar, can fly out like bomb shrapnel to injure people.

bulb temperature

In the evening of autumn, Sergeant Eli was invited to dinner at Miss Murray's house. After the servant opened the door for him, he asked him to sit down in the living room, and then went upstairs to find Miss Murray.In less than a minute, there was a sudden scream from upstairs, and a servant ran down in a panic, yelling: "Hello! Miss Murray has been killed!" Hearing that, Eli ran up and found Miss Murray The door of his bedroom was closed, and he and his servants broke open the door.Miss Murray's room was not lit, and moonlight streamed in through the window.

The servant said to Sergeant Eri: "I knocked on the door just now, but no one answered after shouting for a long time. The door was locked from the inside. I wondered if something happened to the lady. So I looked in through the keyhole, and under the light I saw the young lady lying on the table, and she didn’t move no matter how I called her. Suddenly the lights went out, and the room was pitch black. I guess the murderer must have been in the room at the time, and after hearing the sound, he turned off the lights and fled.”

Sergeant Eli entered the room, which had no cluttered footprints on the floor.Then he touched the light bulb with his hand and found that the light bulb was cold.He hesitated for a moment, turned on the light, and found that Miss Murray had been hit hard on the head.

Eli asked the servant, "When you looked through the keyhole, was the light on?" The servant nodded.

"Then the problem is very simple. Even if you are not the murderer, you are in collusion with the murderer." Eli said to the servant coldly.The servant turned pale with fright and admitted the fact of the crime.

How did Eli judge the servant as the murderer?
The light bulb is the proof.According to the servant, the lights in the room should have been turned off not long ago, and the autumn weather is not cold, so the light bulb should still be hot.

love lies
When a train passed by, a middle-aged wealthy businessman was pushed off the platform and killed by the train.

The railway police rushed to the scene, and all passengers who approached the wealthy businessman were invited to the police station for investigation.However, due to the large number of passengers on the platform at that time, no one noticed the details of the wealthy businessman being pushed off the platform.

When the investigation was clueless, a young woman claimed that out of conscience and justice, she testified that her boyfriend deliberately pushed the rich businessman off the platform.The officer saw the hatred for her boyfriend in her eyes.She said that she and her boyfriend had just gone through a fierce quarrel and then decided to break up. The boyfriend went to the station to see her off.When entering the platform, the boyfriend meets a wealthy businessman and they reluctantly nod to each other. It can be seen that they are old acquaintances with a grudge.She said that when the train passed by, the strong wind of the train blew her backwards. At this moment, she saw her boyfriend push the rich businessman's back with his right hand, causing the rich businessman to fall off the platform and be hit by the train to death.

After listening to her account, the police officer pondered for a long time, and then said to her: "You are framing your boyfriend! This is a crime!"

How did the police officer see through the young woman's lies?
When the train passes by, a low-pressure area will be formed around the body, and people can only be sucked into the train by the airflow, and it is impossible to fall backwards.

The time the pointer stays

On the morning of January 1887, 1, Thames Embankment was in chaos.It turned out that the staff of a dock found that the safe was broken and a sum of money was stolen when they went to work in the morning.

In the evening, the water police found the body of the caretaker. After forensic examination, he was murdered and thrown into the Thames.In the pocket of the deceased was found a high-end pocket watch with very accurate travel time, but it had stopped.Undoubtedly, the time indicated by the hands is a very important clue.But a clumsy policeman actually forgot the rule of keeping the scene intact. Out of curiosity, he fiddled with the hands of the pocket watch a few times.His stupid behavior was immediately reprimanded by his colleagues.

Later, the inspector asked him if he could still remember the time indicated by the hands of the watch when he first found it.When the policeman heard the officer questioning him, he immediately reported that he hadn't looked at the exact time, but one thing impressed him very much, that is, the hour and minute hands overlapped.The second hand, however, stops exactly at a spot on the surface.

After listening, the inspector looked at the watch.Spotted on the surface is 49 seconds.After thinking about it, he determined the exact time when the body was thrown into the river, and it was consistent with the forensic autopsy report.In this way, the scope of investigation was greatly reduced, and the murderer was quickly caught.

Do you know what time the clock hand stops?

In 12 hours, the hour and minute hands have 11 chances to coincide.We know that the speed of the hour hand is 1/12 of the minute hand. Therefore, after the last coincidence, the two hands will coincide again every 1 hour, 5 minutes, 27 and 3/11 seconds.

在午夜零点以后，两指针重合的时间分别是：1点5分27又3／11秒，2点10分54又6／11秒，3点16分21又9／11秒，4点21分49又1／11秒。最后这个时间正好符合秒针所停留的位置，因此它就是侦探所确定的时刻。

Time of death
At 9 o'clock in the morning, private detective Green came to the beach for a walk, and suddenly saw a small sailboat leaning on the beach.When he got to the side of the boat, he yelled a few times into the cabin, but no one answered.As a result, Green became even more curious. He climbed to the deck along the anchor rope, and looked into the dark cabin from the stairs on the deck. What he saw in front of him was a navigator lying in a pool of blood, his chest There was a dagger stuck in the front, and it looked like he had been stabbed to death.

The navigator held a torn old nautical chart tightly in his hand. On the head of the bed where he was lying, there was a candle that had been extinguished. The upper end of the candle was horizontal. Perhaps the navigator was He was killed while lighting a candle to look at the nautical chart. After killing the navigator, the murderer blew out the candle, took the nautical chart and fled.

Green thought it was a murder and the stakes were high, so he called the police immediately.When the police arrived, they started looking for clues.

"The ship was moored here at about noon yesterday, and it was very dark in the cabin during the day, so even if you look at the nautical chart during the day, you need to light candles, so the time when the navigator was killed is not necessarily at night, but what is the navigator's death?" When was it murdered?" The police discussed while examining the corpse.

"The navigator should have been killed around 9 o'clock last night." Green made a decisive judgment.

The time of determination is related to the ebb and flow of the tide. Generally, the interval between high tide and ebb tide is 6 hours, so the last ebb tide was 12 hours ago.Because "the upper end of the candle is horizontal", it proves that the boat is also balanced when it is burning.From this, we can deduce the time when the navigator was killed.

time flies

John, the chairman of a consortium, wants to get rid of his lover Liz, but because he has a lot of illegal business information in her hands, a murder plan is formed in John's mind.

John took Lise to the beach to play.

"I don't know how to swim, so I won't go into the water." Lisi said timidly.

"What are you afraid of when I'm here... I'll teach you how to swim."

Liz couldn't refuse, so she went into the water.

John grabbed Lise's arm firmly and pushed her down...

Then John left the beach. Half an hour later, the police came to the scene for investigation. Although they suspected John, they couldn't find any evidence.

But on the fourth day, the police found evidence and arrested John.

What evidence did the police find?
Lise's body will show obvious finger marks after a few days, which match the size of John's finger, so it can be determined that he killed Lise.

will in a book

Mr. Hank, who lives in New York, is a rich man. He has two older sisters and a younger brother. Because Hank is old, he wrote a will early, planning to put the company under his name and tens of millions of properties To the children of the two sisters.He found the famous lawyer David, and handed over his will to this impartial lawyer.

Soon, Mr. Hanke became seriously ill and passed away within a few days.

On the second day after Mr. Hank's death, Hank's brother's child, that is, Hank's nephew Cowen, came to the law firm.He came to David, took out a will, and said to David: "Dear Mr. David, I know that my uncle gave you a will, but I want to tell you now, the one in my hand The will is the real one. Because it was signed later than the will in your hand, and the heir to the estate written in this will is me."

David thought for a while and said, "Mr. Cowen, how did you get this will?"

"I found it in the "Bible" at my uncle's house. I went to visit him at his house that day, and my uncle was dying, and then he told me that between pages 157 and 158 of the "Bible" he gave me his will ..."

"You're lying!" David scolded him furiously before he finished speaking: "You liar! If you can put this will back in its place, I will recognize you as the heir!"

Cowen was stunned immediately and had to admit that he was lying.

How did David see through Cowen's lies?
Because pages 157 and 158 of the "Bible" are the front and back of a piece of paper, it is impossible for Cowen to find the will sandwiched in it, and it is impossible to put the will back to its original place.

false testimony

Terry's wife was killed, and Terry, who was deeply grieved, told the prosecutor: "I came home very late last night, and I happened to bump into a person who ran out of my wife's room and stumbled down the stairs. Through the door By the dim, ever-burning lamp, I recognized him as Fernando."

Defendant Fernando shouted angrily: "He's lying!"

Terry continued: "Fernando ran about a hundred yards and dropped something that bumped a few times on the rocky slope before rolling into the ditch and sending out a series of sparks in the darkness."

"This is nonsense! False accusation!" Fernando blushed with anger.

The prosecutor held up a bronze statue of a forest goddess: "I'm sorry, Mr. Fernando, we found this thing in a deep ditch. If it was an hour later, the heavy rain might have washed away these clues. The bottom of the bronze statue is stained The blood and hair belonged to Mrs. Terry, and we have a clear fingerprint on the statue—yours."

Fernando retorted: "I didn't go to his house at all. Terry called me at 7 o'clock last night and said he wanted to come to my house to talk about something at 8 o'clock. I waited until midnight, and he didn't come, so I went to sleep. Yes. As for the fingerprints, they might have been left when I played with the bronze statue at his house a few days ago."

The prosecutor felt that the case was very complicated, so he went to Detective Bill, explained the case, and finally said: "Terry and Fernando are colleagues. They used to have a good relationship. Recently, for some reason, the relationship has started to deteriorate."

After hearing the prosecutor's introduction, Bill said, "The murderer is not Fernando, someone framed him. The real murderer is..."

Do you know who the real murderer is?
The real murderer is Terry.The key to the case is the bronze statue.Terry said that what Fernando threw hit the rocky slope a few times, knocking out a string of sparks in the dark, and said it was Fernando's murder weapon.This is a lie, bronze statues will not hit sparks on rocks, which is determined by the physical properties of bronze.So Fernando is not the murderer.

crime under the snow
After the snow stopped, a police car drove by at high speed.

In a clearing not far away, a young woman stopped breathing in a car.She leaned on the steering wheel as if she was asleep.There was five or six centimeters of snow on the car.A long rubber tube was connected from the car's exhaust hole and stuffed into the window slit.There are only footprints of youth on the snow.

"When I found my girlfriend, I quickly found a rock and smashed the glass, opened the car door and turned off the engine to stop the exhaust, but it was too late, and she was out of gas." The young man described the situation to Sheriff Jack.

"I don't see it right. You killed her elsewhere, then put the body in the car and reported it to the police." Jack said in a sarcasm.

The young man still wanted to quibble, but Jack stared at him fiercely and said, "Remember, no crime can be tolerated under white snow!"

What is the meaning of Jack's words?

Since the car was on fire, the engine should be hot, so it is impossible to have such a thick snow; moreover, if the deceased really died of poisoning caused by inhaling car exhaust in the car, there should be signs of struggle, and it is impossible to be like sleeping. It's like ripe.

arson hoax
On Harlan Street in Boston, as elsewhere, there is a wide asphalt road and a variety of shops and housing.The only difference is that the houses from No. 100 to No. 700 on Harlan Street are all exquisite wooden structures. Mr. Sauls, who lives in No. 276, is very satisfied with his residence.

After a while, the fire was finally extinguished, but in this terrible fire, more than 30 houses were completely burned down, and many more houses were seriously damaged.After investigation by the police, it was found that the fire started at the house of Mrs. Esme, a neighbor of Mr. Sauls.The cause of the fire could not be ascertained because the scene was completely destroyed.After finally escaping, Mrs. Esme became unconscious with grief when she heard the news that her husband and child had not survived the flames.

The police called for the doctor, and after a while Mrs. Esme calmed down and continued the questioning, and Mrs. Esme described the cause of the fire.

Mrs. Esme said: "We went to a friend's party last night and didn't come home until late at night. When I came back, my husband and children said they were very hungry, so I went to fry them steaks. When the steaks were almost done , I suddenly heard the child crying, so I quickly put down the steak and ran to the living room. It turned out that the child's palm was cut by the glass. My husband also ran over at this time, and he took the child to the bathroom to wash and bandage, while I Back to the kitchen. Unexpectedly, I forgot to turn off the gas stove when I went out, and the flame ignited the oil, which was already burning in the pot!"
