Sherlock Holmes at Hogwarts.

Chapter 11 Green Light
"It's actually very simple to deduce this..."

Sherlock pointed at Harry's glasses and explained, "No normal family would let you go to a new school wearing a pair of broken glasses that have been taped together many times.

Your clothes are neat, which shows that you have a good living habit, but the style is old-fashioned and obviously doesn't fit you. They hang loosely on your body and are much larger than your figure, so I guess they are old clothes worn by your "cousin".

The old box next to me is covered with traces of bumps and wear, and the marks of time are clearly visible, indicating that it has been in service for many years.

Since you are your cousin, according to the records in "The Rise and Fall of Black Magic" and "Important Magical Events of the 20th Century", your only relative is your mother's sister, so I guess you should live with your aunt and uncle.

From this it is easy to infer that they are treating you..."

"What did you say? I was mentioned in the book?"

Harry looked incredulous.

Sherlock stared at him. "It seems you haven't been reading your books carefully - in fact, I know almost everything about you."

The shock on Harry's face grew even more intense.

Sherlock smiled at him:
"Not only these two books, you are also mentioned in Bathilda Bagshot's A History of Magic, a must-read for first-year students."

At this moment, Harry suddenly felt dizzy.

He calmed himself down and couldn't help asking again, "Then...how did you know it was Uncle Vernon who sent me here today?"

"That's what I was going to say—if you hadn't interrupted me."

"Oh, I'm sorry."

Harry apologized quickly, it seemed like he always messed things up without realizing it.

"It's okay, as long as you don't interrupt me next time—there's a mark on the lower right corner of your baggy clothes where it was pinched by a car door.

As for why I could tell that it was caused by a car door and not something else, it was because different angles and magnitudes of force would produce different effects. Obviously, this mark was caused by the right door of a car.

From your speech and the way you just talked about your dress, it can be seen that you are a self-disciplined person, so you shouldn't have been late today, but you were late anyway.

You were unable to lift the suitcase by yourself just now, and combined with your description of that terrible relative, it is not difficult to judge what he did.

He was not willing to send you here in the first place. He sent you to the station just to laugh at you.

For those who come here for the first time, without careful observation, it is difficult to find that Platform 9 and 3/4 is between Platform 9 and Platform 10.

Sorry, from what I've observed, you don't have that ability yet, so you're only here with help from others."

Sherlock spoke very quickly, about twice his normal speed.

The main reason is that he feels there is really no need to analyze these things.

Although the amount of information seems overwhelming, the evidence is as obvious as a blank sheet of paper splashed with ink.

Of course, there are some things he didn't say.

For example, he found Harry as soon as he entered the platform, and by the way, he also analyzed who helped him enter the platform.

After Sherlock finished speaking, Harry spent several minutes to fully understand the meaning of it, and couldn't help but blurt out:

"fantastic!"

Sherlock shrugged. He really didn't think this skill was worth showing off or praising.

Harry admired him even more.

Harry was about to say something else to express his praise when the sliding door of the box suddenly opened and a head with red hair poked in.

"Sorry, all other places are full, can I come here?"

Harry immediately looked at Sherlock.

The red-haired boy followed Harry's gaze towards Sherlock.

"Of course, Mr. Ron Weasley."

"Thank you."

The red-haired man agreed, and when he pushed the suitcase into the carriage, he suddenly realized what was happening and asked in surprise:

"Wait, d-how do you know who I am?"

"If you want to hide your name," Sherlock pointed at Harry, who was also looking at him with curiosity, "I advise you not to hang nameplates on your suitcases in the future, or to not point the nameplate towards others when you are talking to them."

The red-haired little boy looked down and was stunned.

I had almost forgotten about it myself. This person...seemed quite powerful.

Looking at the red-haired boy, Harry suddenly felt much more balanced.

It turns out that it wasn't that he was too stupid, but that Sherlock was too powerful.

While Harry was secretly pleased, the little boy had already sat down next to him.

The main reason was that he felt Sherlock's aura was a bit too strong, so he chose another person.

Facing Sherlock, Ron's performance was not much better than Harry's just now, and he was also a little nervous.

In this situation, Sherlock naturally took the absolute initiative.

He also had some interest in Ron.

According to records, the Weasley family is one of the twenty-eight sacred pure-blood families and has a long history in the wizarding world.

Red hair is the iconic feature of their family.

The so-called Twenty-Eight Sacred Pure-Blood Families refers to a wizard or wizard family that possesses pure or nearly pure wizard bloodline.

This is also a knowledge point introduced in "History of Magic".

Originally, he planned to use Harry as his entry point to understand the wizarding world.

But from my recent contact with Harry, it seems that Harry Potter, who grew up in an ordinary family, knows less about the magical world than I do, who has only read a book for a month.

In this case, Ron, who came from the Weasley family, was actually a very suitable candidate.

"I'm Sherlock Holmes, just call me Sherlock."

After introducing himself, Sherlock pointed again, "He is Harry Potter."

He paused after saying this.

Because he had already guessed Ron's next reaction.

Ron did not disappoint him.

"Harry Potter? Wait, you said he was Harry Potter! That Harry Potter?!"

Ron's voice suddenly rose.

He immediately realized that this was not a good idea, and quickly lowered his voice, looking at Harry in disbelief and asked:

"Are you that Harry Potter?"

Ron looked directly at Harry.

Obviously, this incident surprised him more than Sherlock's judgment of his identity just now.

Noticing that Harry's face was getting redder and redder under Ron's gaze, and he couldn't say a word, Sherlock simply answered Ron's question on Harry's behalf: "Obviously."

This made Harry and Ron breathe a sigh of relief at the same time, and Harry looked at Sherlock with gratitude.

"I can't believe I'm in the same carriage with Harry Potter."

Although Sherlock already knew from the books that Harry had a huge influence, Ron's behavior at this time was the first time that he confirmed this in reality.

It's getting more interesting.

At this time, Harry also lifted the hair on his forehead and showed the scar to Sherlock and Ron.

Ron's eyes widened in surprise: "Is this what the You-Know-Who did?"

"Yes," Harry nodded, "but I don't remember it anymore."

Ron asked anxiously again, "You don't remember anything at all?"

"Well - I just remember there was a lot of green light, and nothing else."

"Green light? What is that?"

"I do not know either."
