The door knocker made a dull "thump-thump" sound when it hit the door, which served as a doorbell.

Soon, a young woman dressed in a maid outfit with a few pockmarks on her face opened the door and gave them a slight bow: "You are Mr. Mogi, Mr. Mori, and Ms. Chima. I have been waiting for you for a long time."

He then stepped aside to let the group into the house. The main hall of the Twilight Mansion had a symmetrical structure with a wooden staircase on each side.

"Is anyone there?" a rather gruff male voice called out.

After the maid responded, she walked toward the man who was speaking. The man was wearing a pure white suit, had a mustache on his face and chin, and was rather fat.

After seeing the man, the group recognized him as a food detective named Oosuki.

I don't know what he said to the maid, but I heard him shouting, "What? You said the chef suddenly fell seriously ill and can't come to cook?"

He looked very angry: "That's not what we agreed on! I wouldn't have come all this way here if it weren't for this dinner!"

After some discussion, Da Shang Zhu Shan, somewhat annoyed, decided to let him cook dinner. At this moment, Xiao Lan also came out of the bathroom and joined everyone.

After discussion, everyone learned that in addition to the four famous detectives present, there were two other people: a woman and a boy. The word "boy" deeply caught Xiaolan's attention.

She also hoped that the young detective in question was Shinichi, but Conan knew that was impossible, so he thought it should be Hattori.

The maid shook her head and said, "Although the names of these two were indeed on the guest list that the master gave me, we have been unable to contact Mr. Kudo, and Mr. Hattori's mother personally called to decline the invitation because he has midterm exams coming up."

"Where is your master now?" Mogi Harufumi asked.

"Actually, I've never met him yet."

The maid's answer surprised everyone. Under Uncle Mori's questioning, the maid named Ishihara Aki's application process for the job was very strange.

According to her, the job offered good pay and many people wanted to interview. When she entered the interview room, she found only a computer, a banquet instruction manual, and a guest list.

After she reviewed all the documents as instructed on the computer, the computer displayed the message "You have been hired".

In other words, from the interview to the job application and even now to receiving guests, Ishihara Aki, the maid who was hired, has never even met her employer. All subsequent contact has been through phone calls and emails.

This sense of mystery piqued the curiosity of the detectives present, as if they were in the middle of a game.

Harufumi Mogi smiled and said, "As expected, I felt this house was quite interesting from the moment I opened the door. This door handle is also quite interesting."

Ran leaned closer to examine the handle, which now bore some mottled marks. Just then, Mogi Harufumi said, "Be careful, Miss, these are bloodstains from some history."

So close to the bloodstains, Xiaolan quickly took a few steps back. She had thought it was just a scare tactic, but a female voice behind her shattered her self-comfort.

A woman sprayed a few times on the stair railing with a spray bottle, and the white gloves on her hands revealed her identity. Clearly, she was the female detective among the other detectives.

She covered the spot where she had just sprayed with her hand, where some traces were already glistening. She said, "I think it's blood droplets that adhered to the door at a 45-degree angle of incidence. Besides the bloodstains on the door, there are also bloodstains on the walls and floor. Although someone has wiped them, almost every part of this villa has traces of blood."

"It seems that the owners of these bloodstains are definitely not just one or two people." The woman's voice was very calm, so calm that it seemed quite different from her appearance.

A seemingly gentle woman was saying some chilling things, and she did it all with such composure.

"That's a brilliant analysis!" A young voice rang out from the top of the stairs.

The elegant woman's spray bottle just now contained luminol, also known as luminescent ammonia, which is a chemical that, when sprayed on bloodstains, can cause the bloodstains to produce a bluish-purple fluorescence through a chemical reaction.

In forensic medicine, the luminol reaction can identify bloodstains that have been washed off and are from a long time ago, and therefore it is widely used in criminal investigations and other fields.

The young man slowly walked down the stairs. The woman he was praising was named Ikumi Yata, and the young man's name was Saguru Hakuba.

Uncle Mori recognized the name Hakuba Saguru because it was the surname of Police Chief Hakuba. Sure enough, the young man named Hakuba Saguru was indeed Police Chief Hakuba's son.

As he walked down the stairs, he put his hand to his mouth and whistled. As he whistled, an eagle flew down from upstairs, landed on his hand, and stopped.

The eagle's name is Watson, and it is said that because he often works on cases with Hakuba Saguru, he seems to be particularly sensitive to the smell of blood.

Upon seeing the eagle, Guangyou finally showed joy and curiosity for the first time, and also whistled. Watson's sharp eagle eyes first looked at Guangyou who was whistling.

There was a slight movement beneath its feet, but it remained still in Hakuba Saguru's hand. Hakuba Saguru chuckled, "Watson won't listen to strangers, you'd better let go..."

Before he could speak, Guangyou laughed and whistled again, this time a sharper one. Huasheng reacted, flapping his wings and flying to Guangyou's side.

The eagle's claws were exceptionally sharp, so Guangyou deliberately took off his coat, folded it several times, and laid it on his hands before signaling Watson to stop.

Seeing the eagle up close, Guangyou was overjoyed. Eagles are creatures that most boys would find very appealing, especially since in his previous life, a wealthy man in a certain mining area in a certain region didn't only keep cats and dogs, but also tigers, lions, leopards, eagles, and the like.

Normally, eagles wouldn't obey strangers' commands, but Watson had been tamed and had acquired human qualities. If a wild eagle came, even if Guangyou blew his beak until it was worn out, it wouldn't even bother to look at him; at most, it would just leave a pile of bird droppings as a gift.

This made Hakuba Saguru extremely embarrassed, and he coughed twice: "It seems that Watson really likes this child."

After watching for a while, Kōyū raised his hand and gestured for Watson to return to Hakuba Saguru's side.

At this moment, his arm was padded with clothes, and Watson also reduced his strength, but his hand was still faintly painful. If it weren't for the clothes, he would probably be lucky if his hand didn't bleed.
