"Okay, let's go quickly, little girl, just don't forget what you promised me..."

After saying this, the old man ignored her, turned around, and walked tremblingly towards the inside of the cell.

it is good. "

After taking a deep look at the old man, Wu Wanying took the mobile phone that Barry had searched out of the table nearby and quickly left.

The journey back was unusually smooth. Karasuma Ying didn't run into anyone along the way. It was not until she reached the gate of the dungeon that she finally met a male detective.

She had an impression of this male detective. Since they both spoke English, they had chatted with each other in the banquet hall before.

The male detective naturally saw Karasuma Ying who had just come out of the corridor, and his face showed some surprise. He smiled and spoke first:

"Ms. Karasuma, why are you here? Did Ms. Mary ask you to come here to gather information?"

"Huh? Ah, um, yes..." After a moment of hesitation, Wu Wanying quickly reacted and nodded as he said.

[Collecting intelligence? Mary? It seems that something did happen in the palace. Is it related to the previous alarm? ]

"Haha, it seems that Miss Mary hasn't informed you yet." Seeing Karasuma Ying nod, the male detective continued:

"I just heard from my detective friend that Miss Mary has found the murderer who killed Commander Birun, and she is now reasoning up there, so she asked me to go up there quickly..."

[Birun was killed? Up there? In the dungeon?]

Confused, Karasuma Ying immediately opened her acting skills and said to the male detective with a smile:

"I think Miss Mary was so busy solving the case that she forgot about me as her assistant. Mr. Detective, since we've met, why don't we go up together?"

"Okay, let's go up together."

Even)

"The murderer is you, Captain Gunna."

In the watchtower, in front of everyone, Mary directly pointed out Gunna's identity as the murderer.

Everyone in the watchtower, including Barry, was surprised by Mary's sudden accusation.

"Ms. Mary, you said that Captain Gunnar was the murderer of Commander Birun? That's unlikely, right?" Hans said with a smile, "When Commander Birun was murdered, the captain was in the banquet hall with us..."

Mary did not answer him. Her eyes were always fixed on Gunna, as if waiting for his answer.

Being stared at like this, Gu Enna, who was already a little uneasy, became even more flustered, but he still tried his best to show a decent smile and replied:

"Detective Mary, did you make a mistake? How could I be the commander's murderer..."

"Is that all you have to say?" Mary shook her head slightly in a disappointed tone and said, "It doesn't matter. I will expose your murder method with so many flaws bit by bit.

The first point is the time of death of Commander Birun. Based on the condition of the body, I infer that his exact time of death should be an hour ago..."

"An hour ago?" a detective asked, "But didn't Commander Birun talk to Captain Gunnar on the phone just half an hour ago... Ugh!"

The detective suddenly realized something and stopped talking. He turned his head and looked at Gunna with a strange look.

"Yes, that phone call was fake. It was probably forged by recording it in advance. This is not a difficult thing to do. The murderer did this just to forge an alibi for himself.

If you don't believe it, you can ask Commander Barry to investigate the landline phone in the banquet hall and the call records of the landline phone in the watchtower at that time.

I believe that the call at that time was absolutely not made from the landline in the watchtower, unless the murderer had other accomplices in the dungeon at that time.

But unfortunately, according to my investigation, in the murder of Commander Birun, the murderer did not have any accomplices, and this is not wrong."

After explaining the phone call, Mary continued to reason:

"About half an hour before the fake phone call, the murderer somehow managed to get Commander Birun here and attacked him here. The method of attack was to use a rope to strangle Commander Birun's neck from behind, strangling him to death bit by bit."

"Wasn't he hanged?" a detective asked.

"No, the strangulation marks on Commander Birun's neck are horizontal and below the throat. These are typical strangulation marks left by being strangled from behind.

If he was hanged, the marks would have been in an upward arc and above the throat.

Having explained this, Mary continued her reasoning.

"After killing Commander Birun, the murderer first tied one end of the rope inside the watchtower and put the other end around Commander Birun's neck. Then the murderer took out the thin wire he had prepared..."

Mary pointed to the bundle of very long thread and cloth in her hand and said:

"I found this bundle of string downstream of the creek outside the dungeon. The murderer used this bundle of string with extremely high toughness to first pass through the small holes on both sides of the top of the cloth, and then pass it around the back of Commander Birun's belt, using this method to fix the cloth on Commander Birun's body.

Then, the murderer pulled the thin wire all the way down the staircase corridor, wrapped the thin wire around the metal ring of the electric light on one side of the corridor, tied a small loop at the end of the thin wire, and put the small loop on the nail that the murderer had nailed on the inside of the door of the dungeon below near the watchtower.

After doing all this, the murderer returned to the watchtower and moved Commander Birun's body to the windowsill of the watchtower, lowering it in a way that half of it was hanging outside the windowsill and the other half was placed on the windowsill. Because of the pulling of a thin wire, Commander Birun's body did not just fall down.

After placing the body properly, the murderer took a final look at the long cloth, which was very similar in color to the exterior of the castle dungeon. After making sure that it completely covered Commander Birun's body, he finally left the watchtower and walked out of the dungeon through another door that had not been nailed shut.

At this point, the murderer's disguise was basically completed. With his design, as long as someone pushed the door that had been nailed, causing the angle of the nail to change, the thin wire originally on it would fall off immediately.

Without the pull of the thin wire, Birun's body on the windowsill of the watchtower would immediately fall down, and together with the rope tightly tied around his neck, it would create a scene of being hanged.

As for the cloth and thin thread that originally covered him, they would slide down into the small river below the castle due to the effect of gravity.

Here, in order to ensure that these mechanisms can be washed away by the current, the murderer also tied a wooden sign to the end of the thin line. Even if the wooden sign is washed away by the current, the thin line and cloth can be taken away together. "

As she spoke, Mary again gestured to the thin string, wooden sign and long cloth in her hands.

“And the murderer’s idea was indeed successful. I found these things downstream of the creek. Although they were not completely washed away, they were definitely far away from the dungeon.

I think if the murderer is given a little more time, he will definitely go and collect and dispose of these mechanisms himself afterwards, right?"

As she spoke, Mary looked at Gunna, whose face had already become extremely gloomy.

"But Detective Mary, how did the murderer ensure that someone could open the door at the time he wanted?" a detective couldn't help but ask.

"It's simple. It's the sirens and broadcasts from before."

Mary said, turned to look at the silent Commander Barry, and asked again:

"Captain Barry, have the Kingdom police caught the prisoner who escaped from prison?"

After the translator repeated it, Barry spoke up and gave the same answer as before.

"Please rest assured, the Kingdom Police are searching and will soon be able to arrest the criminal."

"Ah."

Mary nodded and did not ask any more questions. She continued:

"The murderer's method was very simple. He randomly selected a suitable prisoner in the dungeon, and probably took the opportunity of delivering food to the prisoner to quietly hand over the key of the cell to the prisoner.

While the prisoner took advantage of this opportunity to escape from prison, the murderer quickly reported the news... I think you all know what happened next.

Regarding this point, the police can interrogate the criminal after arresting him. I believe the criminal's answer will be no different from my reasoning.

The prisoner escaped, the alarm sounded, the guards and the Kingdom Police rushed into the dungeon, the mechanism on the door was triggered, and the murderer returned to the banquet hall at the right time, answered the fake phone call, and led everyone to see the body of Commander Birun, who was finally hung outside the watchtower...

This is the whole process of this case. Is there anything wrong with my reasoning? Captain Gunnar? "

After she finished speaking, Mary looked at Gunna, whose face had already become extremely ugly.

The watchtower fell silent for a moment. Facing the strange looks from everyone, Guenna suddenly smiled. He also looked at Mary and said with a calm smile:

"Ms. Mary is indeed a detective. I really admire her imagination. But I just can't understand why Miss Mary thinks I must be the murderer.

Let's assume that the method you mentioned, Miss Mary, can really be successful. Then there should be quite a few people who can implement this method, right?

Just because I happened to receive that fake phone call and happened to see Commander Birun's body, does that mean I am the murderer? Isn't that a bit too arbitrary?"

"Captain Gunna, when you strangled Commander Birun, he must have put up a very fierce resistance, right?" Mary suddenly asked.

"How would I know about this? I've already said I'm not the murderer..." When asked this suddenly by Mary, Gunna's face looked a little ugly.

"Really……"

Looking at him calmly under her thick sunglasses, Mary said, "Then I don't mind helping you recall the situation at that time.

At that time, in the watchtower, after Commander Birun was tricked by you into coming here, he was completely defenseless and you strangled him with a rope from behind.

While you were strangling him, Commander Birun initially put up a fierce resistance, with one of his hands subconsciously scratching his neck, trying to pull the rope loose.

With his other hand, he swung the cane in his hand vigorously, attacking and hitting you behind him.

During this time, the cane did hit one of your hands and left a wound on the back of your hand.

At the same time, it may have accidentally hit the surrounding walls, causing part of the metal ring at the tip of the cane to fall off.

The metal fragment flew out of the tower and landed on the staircase corridor outside.

As she spoke, Mary took out the piece of metal fragment that she had picked up earlier in the staircase corridor.

On one side of this fragment, there are still traces of coagulated blood.

"Captain Gunnar, the blood on this fragment should be yours, right? Don't deny it, this can be tested for DNA.

By the way, to prove my reasoning, I hope Captain Gunna can show us the wound on the back of your hand. If I am not mistaken, the shape of this wound should be very consistent with the tip of Commander Birun's cane.

Another thing, I noticed before, on the back of Commander Birun's shirt, the small area above the belt also had traces similar to coagulated human blood.

I hope the police can also test this blood stain to see if it matches Captain Gunnar’s DNA…”

"no need……"

Faced with Mary's constant verbal offensive, Gunnar finally lowered his head, and the indifference he had forced himself to show before completely disappeared at this moment.

His face was gloomy, and he looked like a defeated rooster. He smiled bitterly and said:

"No need to check again. Miss Mary's reasoning is correct. I killed Commander Birun...

The method of murder and the subsequent disguise are the same as Miss Mary's reasoning. The same is true for the prisoner who escaped from prison. It is true that I secretly gave him the key. My original plan was to frame him for the commander's death and make him the murderer who took the blame...

Miss Mary is such a great detective. She only came to the scene and took a few glances, but she completely cracked my tricks, without even giving me any time to deal with the evidence..."

"Why did you want to kill Commander Birun?" Mary asked directly, ignoring his flattery.

"There's no special reason, just some personal grudges..." Gunna smiled and replied calmly.

"What personal grudge?" Mary continued to ask.

【This can never be a true reason.】

"This is not something worth talking about. Anyway, it has been discovered..."

He suddenly said something that made no sense, and when everyone was off guard, Gunna suddenly pulled out the pistol from his waist and aimed at his own temple.
