After thinking of the possibility of the demon dog's owner, Klein immediately changed his strategy and recounted in great detail how he and Isengard Stanton met because of the serial murder case.

In addition, he also took the initiative to mention that Eisinger Stanton organized a group of detectives to investigate the serial murder case and successfully obtained part of the reward.

“In that commission, although I only provided some ideas, or, to use the professional terminology of the private detective industry, provided consulting advice, Mr. Stanton still considered me to have made the greatest contribution, so I received the largest reward,” Klein concluded.

The two police officers in charge of the interrogation quickly recorded these circumstances and asked if anyone could prove the above. Klein gave the names and addresses of private detectives such as Stuart and Kaslana.

"Very good, Mr. Moriarty, your answer is detailed enough." A police officer stopped writing and asked, "How long did you stay in Isengard Stanton's house today? I mean, from the time you entered until we found you."

Klein thought for a moment and answered directly without asking for the opinion of Lawyer Jurgen:

"About two to three minutes."

He was speaking of his true personal feelings.

Another police officer raised his eyebrows and said:

"Several nearby residents can confirm that you entered Isengard Stanton's home at around 2:10 pm, and we arrived at the scene at 2:28 pm, which means that you stayed in the house for about 18 minutes, not two to three minutes!

"What on earth were you doing all this time? Why didn't you leave and call the police?"

Eighteen minutes had passed? Klein frowned.

He felt that he and the person who was watching silently were in a stalemate for no more than a minute, so how come eighteen minutes had passed?

Was it the strange feeling of being stared at that confused my grasp of time, or was it some other reason? Was it the other party's extraordinary ability? If he was really the owner of the demon dog, he would be at least Sequence 6, most likely Sequence 5... As Klein pondered in confusion, Jurgen leaned forward, ready to accuse the police of misleading him with his questioning.

This was not a very sufficient reason. He just wanted to interrupt the rhythm of the interrogation in this way and delay the obviously unfavorable question just now.

At this moment, Klein raised his hand and rubbed his forehead and said:

"Everything I just said is true. In my personal opinion, I was in Detective Isengard Stanton's house for only two to three minutes."

At this point, he emphasized:

"Well, in my personal opinion."

The two police officers looked at each other and wrote this down.

After a brief silence, the police officer who had asked the question just now said:

"During those eighteen minutes, a servant who had just returned from an outing rang the doorbell, but no one answered. He looked in through the oriel window and saw the bodies scattered all over the floor and you standing at the door of the living room.

"He was terrified and ran like crazy to the police station to report the crime, which many passers-by and some residents can confirm."

Klein ignored Lawyer Jurgen's eye contact and shook his head.

"I didn't hear the doorbell."

The two police officers looked at each other again, without making any comments, simply recording.

They asked some questions about other details, and Klein, who had never done anything and felt guilty, answered all of them truthfully.

At the end, he couldn't help but express his concern:

"Have you found Detective Isengard Stanton? I don't see a body in the living room, so he should still be alive..."

A police officer tapped the table with his pen and said:

"This is also something that puzzles us. In the entire house, only the living room showed signs of fighting, and the windows were closed and had not been opened for many days. You know, this is normal in Backlund's autumn and winter.

"The attacker and Mr. Isengard Stanton strangely left the room. No one knows where they went. We didn't find any clues in other parts of the house or the surrounding area, not even any bloodstains."

Without waiting for Klein to speak, he asked and answered himself:

"You're definitely talking about the living room door and the front door, but multiple people confirmed that there was no chase in the area, no one was taking hostages or leaving with a body."

Maybe the incident actually happened in the middle of the night? Maybe they would pass through the wall? Klein silently offered other possibilities in his heart and prayed silently:

May the goddess protect Detective Isengard Stanton and help him escape the disaster.

——The Goddess of Night is the queen of disaster and fear.

After the interrogation, Klein was handcuffed to a small room, and the police sent someone to follow Lawyer Jurgen to No. 15 Minsk Street to retrieve the letter evidence.

The process lasted until the evening, when Klein was finally granted bail of 50 pounds.

"This is much more expensive than last time. It's hard for ordinary private detectives to come up with so much cash in a short period of time." After leaving the gate of the Hisak Police Station, Klein straightened the collar of his tweed coat and complained to Lawyer Jurgen.

Jurgen still had that professional and serious expression:

"The situation was favorable to you last time, but this time many doubts point to you."

He asked the rental carriage to stop and turned his head to look at Klein seriously.

"Sherlock, I'm your lawyer. Before you answer the police's questions, it's best to have some communication with me, even if it's just eye contact.

"Don't just speak up if you think it's okay. It's easy for untrained people to leave room for error with their words."

This... I'm used to making up stories and solving problems on my own... Klein thought back to what happened and laughed dryly.

"Okay, I'll pay attention."

Jurgen said nothing more and got into the carriage.

Klein sat across from him and thought about the attack on Detective Isengard Stanton.

As he was thinking, he suddenly heard his stomach growling.

It was already half an hour past the normal dinner time... Klein took out his gold-cased pocket watch and opened it to take a look.

He didn't plan to waste any more energy preparing food and started thinking about which restaurants were worth looking forward to.

At this time, Jurgen raised his eyelids and said:

"I've asked my grandmother to prepare dinner for three."

"How can this be so embarrassing?" Klein was stunned for a moment, then smiled and said, "Mrs. Doris's craftsmanship is always something to be admired."

…………

When the two returned to Minsk Street in Cherwood, it was already completely dark. The light from the gas street lamps was even brighter than the vague red moon in the sky.

After having dinner at Lawyer Jurgen's house and petting the cat, Klein walked back to the outside of House No. 15 in the cold and humid air.

He flipped through the mailbox out of habit and took out a copy of the Backlund Evening News that had just been delivered.

Klein opened the door and walked into the house with the newspaper in his hand. Just as he put down his cane, he suddenly felt something was wrong.

His fortune teller's spiritual intuition told him that a stranger had entered his home!

Is it the police who came to collect evidence earlier? Klein looked around cautiously and suddenly found a letter on the coffee table.

There should have been only newspapers there!

Klein entered the living room, always on guard against attacks, and moved closer to the coffee table. During the entire process, the surroundings were quiet and silent, without any abnormality.

After looking down at the letter for a few seconds, Klein took out his black gloves and put them on before picking it up and opening it.

Inside the envelope was a thin piece of letter paper. After unfolding it, a dark red color immediately caught Klein's eyes, and a faint smell of blood lingered in his nose.

On the letter paper, a line of words was written in coagulated blood:

"You are all going to die!"

Is this... really the master of the demon dog? Is he avenging the people who caused his men's deaths? He is really bullying the weak and afraid of the strong. Why doesn't he just go find the powerful Nighthawks who are responsible for the cleanup operation? Klein's heart tightened, and many thoughts flashed through his mind in an instant.

But he quickly denied his complaint. It was the most normal choice to start revenge on the people who could be dealt with first, just like he had been in Backlund for several months and never thought of looking for Ince Zangwill, but kept chasing Lanevus.

After looking around again, Klein gradually felt that this matter was a bit confusing:

"You're taking revenge in such a blatant way. Aren't you afraid of being watched by the powerful officials? Is this his potion role-playing requirement?

"Or, because Detective Isengard Stanton escaped, he knew that he could no longer eliminate the targets one by one in secret, so he had to try another method. But this method is meaningless, right?

"Also, when we were at Detective Stanton's house, he had clearly locked onto me and was watching me the whole time, so why didn't he do anything? Would he still be concerned about an ordinary private detective like me?

"No, that's impossible... He knows I'm a Beyonder? It's possible. Because of the side effect of the Master Key that made me get lost, I ran into the demon dog directly. It saw my appearance and figure. Although I disguised myself to a certain extent at the time, I don't know if the 'devil' can see through this...

"Perhaps, after that incident, it was presented to its owner in some way...

"But I couldn't even defeat the demon dog at that time and could only flee in panic. What should he worry about? Unless he was worried about something else, such as Isengard Stanton who was hiding nearby due to injury?

"He wrote to me so ostentatiously. Did he think that a wild Beyonder like me would not dare to seek official help?"

With a lot of questions in his mind, Klein checked the house and went all the way to the second floor.

When he opened the bedroom door, another letter caught his eye.

The letter lay quietly on the desk, as if it had been waiting for a long time.

Klein picked up the package, opened it gently, and saw a line of words outlined in dark red blood:

"You're next."

The next one... How arrogant... Klein couldn't help but sigh.

At this moment, he suddenly felt something in his heart, raised his head and looked out the window.

Opposite were several two-story houses, each with its lights on.

The glow of the gas street lamps shone on their outer walls, forming areas of alternating light and dark.

Suddenly, the shadows in those areas squirmed and twisted, forming a black figure in a neat tuxedo.

The shadow raised his right hand, made a gun shape, and pointed it at Klein.

Immediately, it retracted its arm and blew at the "muzzle".

Immediately afterwards, it fell backwards silently and transformed into countless disconnected shadows.
