Film walked back and forth between the body and the door several times, bent down from time to time to check the powder on the ground.

"Did you see anything? Newcomer."

Filming thought for a while and said, "There are obvious signs of dragging on the scene. From here to outside the door, it is not possible to tell whether it is before or after the fire. In short, for some reason, the two of them ran outside the house, but in the end the woman was dragged back to the room by the man. The door was locked. The woman struggled very hard, but the man was indifferent. They had been stalemate here for a long time, and the fire should have spread at that time."

"That's why I said this was suicide together."

Film walked to the half-destroyed door, took out a metal stick and plucked the lock core: "But the last door lock was opened halfway. A man or a woman had thought of opening the locked door, but was forced to give up for some reason."

"It's normal. This is the survival instinct of people at the last moment. I guess they have no strength. The fire makes them inhaled too many particles, blocking their breathing, and feeling weak."

"It's possible." Feilin nodded in agreement and said, "It's also possible that the woman wanted to run out, but was stopped by the man when she unlocked halfway, but what I care about the most was the source of the fire."

"The source of fire?"

"Yes, I have been searching in the room for a long time. Apart from the burned items, I did not find any real fire. There were empty wine bottles in the room, but there were no signs of alcohol burning nearby. The charcoal ash in the fireplace had not been cleaned for a long time. Obviously, it was not the burning caused by firewood. They couldn't afford lamp oil, and it was even more impossible for candles. The only thing I found was this one that looked like a fire."

Film rubbed the off-white particle powder in the corner of the wall with his feet.

Sirifer came over and was about to rub his hands a little, but was stopped by Film.

"Don't dip it with your hands, don't smell it, it's phosphoric acid."

"Phosphate?" Sirif thought, "You mean the burning substance is white phosphorus?"

White phosphorus will absorb heat and ignite after contacting the air, forming white mist. When the fire is extinguished, the water will react with the reactants, and finally obtain this white granular product phosphoric acid.

"It's logically reasonable," said Filming, "but it's impossible."

"Why?"

"Because of the temperature, the temperature is too low now, and there is no heating facility in the house, even white phosphorus is not so easy to cause spontaneous combustion. Do you have to open the oral cavity of the men and women's corpses to check? Although the body has been carbonized, the direction of the combustion seems to occur from the inside out."

"You mean, someone was deliberately left at the scene. Is this a homicide case?"

Filming said: "It is not certain whether it is murdered or not, but I can be sure that the purpose of the appearance of phosphoric acid, the final reactant of white phosphorus, should be to hide the real cause of the fire, some kind of fire that can burn in the body... Deputy team, can we identify the substances in Shu?"

"Jorry probably won't, but I can find someone who can."

Sirifer looked at Film again: "Melrose, I'll ask you again, do you really not plan to leave this smoky police station and go to other areas to develop? With your ability, I really don't think this place is suitable for you."

Filmen smiled: "The change of two-way situation may not necessarily require me to adapt to it, but it may also be to adapt to me."

...

...

Bang!

When he returned to the police station with Siliver, Filmen met the little boy from yesterday again and was hit by him again.

Tsk, I really don't give up.

He originally planned to capture Amy for the current situation, but found that the other party did not steal his wallet, but stuffed him a small piece of paper.

"What's wrong?" asked Cyriver.

"It's nothing." Filmen smiled and said, "Deputy Team, you go back to the office first, I'll catch up later."

Filmen found Amy who wanted to see him alone in a remote alley.

"Tell me, what bad idea is it to come to me?"

Amy looked at him and said, "You're a policeman."

"Yes, I told you yesterday, now do you believe it?"

"You and the man just now came out of my house."

"Home?" Feilin immediately reacted, "You mean, the couple who were burned to death, are you their child?"

Amy nodded and asked again, "Do you know... how they died?"

Filmen narrowed his eyes and thought for a moment and said, "Others say that the fire was released by your father himself, and they committed suicide."

"What they said was wrong!"

"How do you know that something is wrong?"

"I...I saw it."

"What did you see?"

"I saw—" Amy bit her lip lightly, as if he was hesitating.

Film looked at him for a while, then suddenly waved his hand and said, "Forget it, I'm not interested."

Amy said anxiously: "I'll tell you it's."

"But I'm not interested anymore, so I don't want to listen." Filmen turned and walked out, "I'm only interested in interesting things."

"I want to know the results of the police investigation!" Amy growled behind her.

"Wait for the announcement from the police station, boy."

"etc!"

Amy ran up quickly, grabbed the corner of Filman's clothes, took a deep breath, and said:

"girl."

"Um?"

Filmen turned around and saw Amy pulling the turban off, revealing her long braided braids behind her head. He, or she looked straight into Filmen's eyes: "You have always called me a boy, but I am a woman."

"Then your name." Feilin didn't notice her lying yesterday.

"My name is Emilia."

So that's it. Amy is Emilia's nickname or abbreviation, so when she said it, Filming didn't notice it.

The little girl said, "Now are you interested?"

Filman thought for a while and said, "It's interesting."
