"Sewage and wet mud?"

Annick remembered that this person had been staying in the building last night. It was his company's subordinates who were responsible for welcoming the guests outside and seeing them off at the end.

A respectable business tycoon would certainly not allow himself to wear dirty shoes to meet guests, unless the dirt on his leather shoes was stepped on during his trip to a certain place last night.

Annick looked at the hotel opposite. There were no puddles on the road from the mansion to the hotel. So where did Connell step on these?

"I have a headache. I happened to attend a meeting of the Classical Literature Society last night."

Annick recalled that he was squatting in the bathroom at eight o'clock in the evening and failed to notice whether Cornell was in the court.

Let's ask the captain later. We should also check out Cornell's room. Maybe we can find out the details.

"By the way, Mr. Forensic Medical Examiner, what is the approximate time of death of these two people."

"I checked the degree of rigor mortis and took into account the temperature. The approximate time of death was 12 o'clock last night, with an error of one hour."

"We left at ten o'clock last night. Both of them should have been alive at that time. I don't know what time the poison needle device in Eva's bag was put in."

"Didn't she bring it herself?"

"It's unlikely. If you really wanted to kill someone, why would you bring two poisons with you and accidentally kill yourself?"

The two were chatting, and Captain Torre rushed in excitedly, holding two small bottles in his hands, which were about the size of pepper and other condiments.

"I found it in the trash can in the women's bathroom. Fortunately it wasn't taken away."

"What is this?" Annick asked.

"You have to find the poison. There is still some powder left in it."

Annick looked carefully at the two bottles, and there was indeed a little powder left inside. One was yellow-white crystalline powder, and the other was whiter, with yellow-white powder and white translucent particles.

"I feel like the whiter bottle of the two bottles is mixed with something like table salt."

"Is there one? Why didn't I see it?"

Because you are blind. Of course, Annick did not dare to say it out loud. It was not good to complain about a police officer who was more senior than him.

"Perhaps Captain Torre is not used to seeing this. By the way, the two bottles of wine and these two bottles also need to be sent for testing. It seems that this kind of toxin is beyond the scope of my knowledge."

"Okay, can we close the case?"

"Don't worry, I want to go see Mr. Cornell's room."

The three of them walked out of the room. Captain Torre found the seal in his pocket and sealed the room.

"Let the little black men come and see us."

This veteran has already made up his mind to hand over this case.

"Captain Parker, do you have any information?"

Seeing Captain Parker and several maids asking questions in the lobby, Torre said hello.

"There's not much progress. Except for a few guests who drank too much and stayed in a few guest rooms to rest. No one else stayed."

"Where is Mr. Cornell's room?" Annick asked.

"On the west side, that's the innermost room to the north. The door is unlocked." A maid replied.

"Captains, I think we need to go in and take a look."

"Let's go, I don't know what you can find."

The master's room was not big, and Annick was a little curious as to why he didn't choose the one across the street. He might have been accustomed to thinking that it would be better to face the south and have the sun.

In addition to the heating closet, there is only a desk and two chairs in the room. A large wardrobe and a large bed. There is a knob-type safe under the desk.

"Captains, please check the closet and desk. I'll check if there are any secret passages or compartments."

"Secret passage? Are you kidding me?" Captain Torre asked.

"No kidding, I feel weird about the mud left on Cornell's shoes. I have a guess and need to verify it."

The three of them divided the work. Captain Parker went to check the closet, Torre went to look at the desk, and Annick squatted on the ground and tapped the floor with his fingers.

"There's no problem, all that's left is the bottom of the bed." Annick knocked around the room for a long time, but couldn't find any hollow space, and finally looked towards the bed.

He used to hide money on the floor of his bed. Thinking of this, Annick approached the bed, squatted down and looked at the floor at the corner of the bed carefully.

Sure enough, there were signs of dragging. There must be something under the bed.

Annick grabbed the edge of the bed and pushed in hard.

There was a squeaking sound from the friction between wood and wood. This bed was heavier than expected, and it should be made of fine perennial wood.

After a lot of effort, Annick pushed the bed to the wall, then squatted down and continued to knock on the ground, making a dull echo on the floor under the original bed.

That's it, Annick tried to lift up the wooden floor with his nails, and an iron plate with a gripper was exposed underneath.

"Here, we've made a discovery." Annick greeted.

"What? I also found something here." Captain Parker came over from the closet holding a set of dark blue miners' clothes.

"I didn't find anything right now. They were just daily business items, and there were only a few burnt ashes left in the trash can." Captain Torre complained.

"It's okay, I think there will be unexpected developments under this iron plate."

After saying this, Annick grabbed the iron plate and pulled it away, revealing a hole underneath that was only for one person to climb down.

A rope ladder was set up on the cave wall, which seemed to be specially prepared for climbing up and down.

"I want to go down and have a look. Do you want to follow me?"

"Just go down alone. Take out your gun. If you encounter danger, remember to climb up quickly." Captain Parker said.

"Okay, you guys stay at the entrance of the cave, I'll go down and take a look."

After saying that, Annick unbuttoned the holster, ensuring that he could take out the pistol immediately, and then climbed down the rope ladder.

It was dark, but fortunately there was a lantern nearby when it touched the ground. After lighting it up, Annick observed the entire tunnel. The tunnel was not high, just big enough for a person to pass through, and the sides were reinforced with wooden boards to prevent the soil on both sides from collapsing.

After groping along the tunnel for dozens of yards, Annick noticed many small bags hanging on the wall along the way, containing change, some canned food and even a shotgun at the end.

"I don't know if there is a concept of survivalism in this world. Mr. Cornell is obviously ahead of the times." After teasing the late gentleman, Annick pushed away a wooden board blocking the way.

"Crash."

There was a sound of water flowing. There was a fishy, ​​disgusting smell in the air.

"This is the city sewer, right?" Annick said to himself when he saw the scene in front of him.

Jumping down from the tunnel, stepping on the stone-paved ground, you will see a flowing underground river a few yards away.
