7pm, London.

Sherlock and Harry arrived here on a dirty street with several dilapidated buildings, a bar, and a messy wall.

"Can't we move directly into the Ministry of Magic?" Harry asked.

"If you are an employee of the Ministry of Magic, you can directly move the Phantom into the Ministry of Magic, but visitors cannot. The entire Ministry of Magic has anti-phantom into the body, which is similar to Hogwarts. Only employees who have been opened for permission can go in directly."

Sherlock took him to a tattered red telephone booth, pushed the door open and walked in.

The phone booth looked too dilapidated, and the door seemed to have some problems. When it closed, it suddenly felt some pulling force and hit the back of Harry's head.

Harry squatted on the ground with his head in pain and took a breath of air conditioning.

Sherlock reminded.

"Be careful."

"It's okay, I just ran into it by accident."

If it were before, Harry would have thought it was because Sherlock had wished him a happy birthday, but now he just felt that he was accidentally.

Sherlock was holding a microphone in his hand. Although it was his first time to enter the Ministry of Magic, how to enter as a visitor was written very clearly in the original owner's diary.

The original owner went in this way on the first day he came to the Ministry of Magic to look for a job.

He pressed the numbers "62442" on the phone, and soon, a cold female voice rang from above the phone booth.

"Welcome to the Ministry of Magic, please name your name and do things."

"Sherlock Forrest and Harry Potter, at the invitation of Kingsley Shackle of the Auror Command, went to help study a case that Auror is investigating recently."

Kingsley had obviously said hello to the receptionist before, and soon the female voice responded.

"Thank you." The woman said in a cold voice, "Please pick up the badge, don't be in front of your clothes."

Two square silver badges slipped out of the metal chute that was usually used to exit the coin, Sherlock picked it up and handed him the one with Harry's name written on it.

Harry saw the content on the badge: Harry Potter, assisting in the investigation.

"Guests from the Ministry of Magic, you need to be inspected at the security checkpoint and register your wand. The security checkpoint is located at the end of the main hall."

The receptionist's voice rang again. After her cold tone ended, Harry suddenly felt the entire telephone booth falling!

The crosswalk outside rose higher and higher, and soon a darkness fell above their heads.

They arrived underground after about a minute of sinking.

Before the telephone booth stopped, it suddenly vibrated, causing Harry to fail to stand firm, his body suddenly leaned forward, and his forehead hit the glass door again.

"Ministry hopes you have a good day," said the receptionist, and the door of the telephone booth opened.

Sherlock walked out with Harry, who was covering his forehead again, looking in pain.

"You've been careful, now you've got it, and you've hit you in the front and back." Sherlock shrugged.

Harry looked dull. Once he could have been accidentally, but twice he felt something was wrong.

But at this time, he was still lucky and followed Sherlock to the foyer to register his magic wand.

As a government in the British magic circle, the Ministry of Magic should have been magnificent. There is also a fountain in the golden hall, and a group of pure gold statues stand in the circular pool, which are larger than real people.

The most conspicuous one is a noble witch, holding her wand and pointing straight to the sky. Around him is a beautiful witch, a horseman, a goblin and a house elf.

The horseman, the goblin and the house elves all worshiped infinitely, looking up at the two wizards.

When Sherlock was checking the wand, he thought about the purpose of this group of statues, and there was no other benefit except to allow the wizard to improve his sense of self-satisfaction.

Not to mention the race like the domestic elves, which has been completely domesticated, will definitely arouse the disgust of horsemen and goblins.

With this statue, if he was a fairy or a horseman, he would never step into the Ministry of Magic.

No wonder the Horseman Contact Office has been established for so many years but has not contacted a Horseman, and the fairy was only defeated after the rebellion.

After taking Harry to check his wand, Sherlock got rid of the inspector who noticed Harry's identity and kept staring at his forehead, and walked straight into the elevator.

Not only were there people in the elevator, but there were also many paper planes coming in and out, and one of them was almost hit by Harry's forehead that had just been injured.

"These are notes used by the Ministry of Magic to deliver messages." Sherlock introduced to Harry.

In fact, this is also the first time he has seen the real thing with his own eyes. He has only seen him depict it in the original owner's diary.

They took the elevator and arrived at the Magic Law Enforcement Division on the second floor.

Almost no one came down on this floor, only Sherlock and Harry were brought.

"What case are we here to help with? Professor." Harry couldn't help asking now.

"A series of murders." Sherlock said with a serious expression.

Hearing his words, Harry's breathing became heavy and he didn't ask any more questions.

They walked a corner and came to a room with the door sign saying "Case Investigation Room".

Just as Sherlock wanted to knock on the door, the door was suddenly opened from inside.

Kingsley, wearing a cloak, walked out of the house as if soaked in water. He kept emitting ashes and despair.

Sherlock frowned and glanced at the monster, and recognized that this was the prison guard of Azkaban Prison - the Dementor.

"Ah, Sherlock, you've arrived." Kingsley's face showed a look of surprise.

Although the aura emitted from the dementor made him feel a little uncomfortable, it had no more impact. Sherlock nodded.

"This is?"

"This time, the Dementor leader who came out of Azkaban came here to cooperate with us in doing some investigations."

The moment Harry saw the dead creature, he felt as if he was stuffed into ice water.

He saw the monster's hand, covered with scars, as if his whole body was rotten.

The cold breath kept wrapping him, turning everything in front of him into a dark color. Harry gasped quickly, his breathing sound became louder and louder, and finally he felt the whole world spinning constantly.

"Plop!"

A heavy voice sounded, Harry rolled his eyes, his body fell backwards, and fainted on the ground.

This shocked Sherlock next to her. At this time, Kingsley also discovered Harry following Sherlock.

They hurriedly helped Harry up from the ground.

"How did you bring him here?" Kingsley asked with a frown.

"I was going to celebrate his birthday, but I received a letter from you. Harry didn't want to go back to his aunt's house again. I couldn't let him stay alone, so I could only bring him with me."

"Sorry, this is my problem."

Kingsley said with a remorse, then he looked at the dementor.

"You go first, remember to restrain your kind. If any dementor attacks happen, the Ministry of Magic will never give up."

The dementor did not respond. It seemed to have glanced at Harry, who had fainted, and then left the corridor flutteringly.

Sherlock and Kingsley carried Harry to the Auror Command, and asked Tonks, who was in the middle of the job for a while, to help take care of him, and then returned to the case investigation room.

"You should have also seen news from the Prophet Daily these two days, and Black escaped from that prison."

On the way, Kingsley told Sherlock about the purpose of calling him over.

"After Black escaped, the dementors were extremely angry. This was the first time in history that someone had successfully escaped from it. So they began to leave the prison in large numbers and search for the escaped Black, which the Ministry of Magic also agreed."

"But just after these dementors came out of prison, there were six deaths these days."

"The first five cases were all attacked by Muggles, and the way they died was the same. The body was still alive, but the soul was sucked."

"The incident department was still having a headache about Black, and the people attacked were all Muggles, so the above did not pay attention to it."

"But just yesterday, a wizard died, and his way of death was exactly the same as the five Muggles before. Sklinger (Director of the Auror Office) took it seriously and specially made an appointment with the leader of the Dementor to come to the Ministry of Magic to cooperate with the investigation."

"The way those people died was exactly the same as the way the Dementor kissed the prisoner, and we have always suspected that it was the Dementor. You know, those guys have never been honest, let alone come out of that prison this time."

"But the Dementors' leader said that none of the six attacks were done by them. The Dementors said they had a feeling that something terrible landed on the Isle of Great Britain, and all the souls of the dead were eaten."

"You have always been an expert in black magic defense. You did a lot of research on dementors in the department, so I want to ask you to come and see if you can find anything."

Sherlock learned the whole story from Kingsley, and then followed him into the case investigation room.

It was empty here, with only six beds, and a body lay on each bed.

No, it can't be called a corpse, because these people can breathe and have heartbeats, but they act like dead people, their expressions are terrifying and ferocious, but there is only a dead ashes in their eyes.

Sherlock has studied the most in the past year, the field that the original owner has been studying - the black magic defense technique.

Including the two books he wrote and published, "Guide to Identification of Dark Creatures" and "Defense Spells", Sherlock reads it thoroughly and studies it thoroughly.

Among them, there are professional research on dementors in the "Guide to Identification of Dark Biology".

Because the creature Dementor is essentially the darkest creature in the world.

If it weren't for the lack of eradication and there was no other better solution, the Ministry of Magic would not compromise.

Yes, having them become jailers in Azkaban is actually a compromise.

Sherlock walked to a living dead man and tapped him gently with his wand. Kingsley introduced him to the man's message.
