The Cthulhu of Hogwarts

The door to the attic on the top floor of the office building was ajar, and the door plate reading Frank Detective Agency showed that Xing Ze and the others had not found the place.

John carefully and skillfully moved to the side of the door, and he gestured to Xing Ze with the wand in his hand.

Xing Ze nodded and walked to the other side of the door. When both of them were ready, he gently pushed the door open.

The wooden door slowly moved backwards. John looked inside, then suddenly jumped out of hiding and kicked the door open.

"Safe," he said, putting away his wand.

Xing Ze followed Zhou into the room, and it was obvious that the detective did not like spacious places. This narrow attic looked like a dwarf standing in a crowded subway.

, the floor-to-ceiling windows can clearly see the floors opposite.

The room was in a mess. John walked into the living room to check the situation, but was stopped by Xing Ze.

"Don't destroy the scene, just stand outside and watch. We will go in after Ruiben arrives."

"Just stand here and watch?" John felt a little confused. Although the whole room could be seen at a glance, judging from the situation in the room, it was obvious that a fierce fight had taken place.

If you just stand here, you will not be able to see many corners clearly, and John is not a patient person.

"For Merlin's sake, Xing Ze, something must have happened to that guy. We can't just stand there like this."

"I didn't just stand there stupidly." Xing Ze replied while carefully observing the entire room, trying to find more useful clues from the messy scene.

He entered the house and walked in a hurry, so he didn't notice the bulging doormat under his feet. Xing Ze's eyes fell on the doormat with a corner kicked up.

He must have tripped and dropped the matchbox. Xing Ze took a few steps forward and picked up the paper flip-top match black.

"I thought we shouldn't destroy the scene." John said out loud.

"Believe me, the police's investigative capabilities are much higher than ours." Xing Ze put the matchbox into his pocket, "But there is one thing, they will hide something from us. So we need some trump cards to exchange."

After speaking, he continued to analyze the situation in the room. The clue wall was destroyed, which showed that it should be related to what Frank was investigating.

Xing Ze walked away and looked at the desk. As mentioned before, he was in a hurry and didn't even have time to push the drawer back. The murderer might have opened it.

Well - Xing Ze frowned and thought for a while, but still rejected the idea. If the murderer opened it, he shouldn't have only opened one drawer.

Mr. Detective picked up the necessary information and put it into his briefcase. Xing Ze's eyes stopped next to a vase. The brown leather briefcase was left behind the vase, but there were no scattered documents.

.

The murderer took away the investigation information. Very good, my workload has to increase again.

"You've been looking around like an owl since the beginning." John leaned over and said, "You didn't find any mice."

"Hmm." Xing Ze pointed to the hole in the wall opposite, "Bullet hole. Did you see Frank's weapon when you hung him upside down last time?"

"He had a gun on his waist, a wheeled gun."

After listening to John's words, Xing Ze lay on the ground.

"Now you're lying on the ground like a groundhog again."

The bullet casing is 38 caliber, which matches Frank's gun. But why, why is the bullet hole in the wall?

Xing Ze got up from the ground in confusion and looked at the ajar front door again. He thought about it for a while, then turned around and scanned the room.

"No blood."

John frowned and asked, "What?"

"No blood, no blood stains." Xing Ze said, "It's really interesting. There was such a fierce battle, but there was no blood stains at the scene."

"Maybe someone used magic to clear it." John took out his wand and cast a tracking spell. As a former Auror, he had never forgotten the tracking spell. But nothing happened.

"Remember to teach me this next time." Xing Ze said.

"Why do I feel like you are mocking me?" John spread his hands, "I'm not a wizard. The tracking spell found nothing. This place is as clean as my purse. So, what do you think? Or should we wait for that?

After a black brother arrives..."

"He came back from outside and tripped over the doormat. He didn't fall, but he kicked his left foot hard on the ground and left a footprint." Xing Ze took out a handkerchief from John's front pocket, then squatted down and used it.

The handkerchief picked up the dirt around the footprints.

With his keen sense of smell, Xing Ze could smell the poisonous smell of snake grass coming from the soil even without putting it under his nose.

"I bet he had just returned from the scene of four corpses. He walked straight to his desk with a clear goal. He found the investigative materials and planned to leave here with them. He knew he was being followed.

, and is still in danger.

"So before replying, he contacted Burke and asked to meet A. He picked up the briefcase and was about to leave. Something attacked him from behind..."

"Wait a minute," John interrupted, "from behind, not from the front. Why can you tell it's from behind."

"Bullet holes in the wall." Xing Ze said, "If those bullet holes were caused by Frank opening the door and shooting, the bullet casing should be closer to the door, not to the middle of the room. As you can see, this place is obvious at a glance.

Can see everything."

"Maybe the other party waited until he got to the middle of the room before attacking."

"Look, John, you can obviously think." Xing Ze mocked, "Don't forget, our detective stumbled when he came in. That attack is the best time, if the other party wants his life.

"

"So what is the killer waiting for?"

"Investigation information." Xing Ze pointed to the empty briefcase, "I had the same doubts as you before, why didn't J. kill Frank when he was most vulnerable, but had to wait until he was on guard. Until you

A tracking spell was used."

"But my tracking spell didn't find anything."

"You should look more carefully. Some magic traces stayed in the open drawer for a while. Remember what you said before? Although Frank is a squib, he can also do some magic spells."

"He cast a spell on the drawers to ward off thieves."

"Yes, just like a safe."

"And the other party obviously doesn't have the ability to lift the spell, so he has to wait for Frank to take out the investigation information before killing him."

Xing Ze nodded, "He attacked from behind, but Frank must have sensed something. His briefcase flew away, and the pistol had little effect on the attacker."

As he spoke, Xing Ze looked at a broken chair, "The other party is very strong. And..." He walked to the edge of the chair and used a handkerchief to remove some fragments.

"And there are sharp claws." There are several deep claw marks on the ground of the fragments, which are consistent with the claw marks on the wall where the clues were destroyed.
