Sherlock Holmes at Hogwarts

“Actually, deducing these things is very simple…”

Sherlock pointed at Harry’s glasses and explained, “Normal families would never let you wear such broken glasses, patched up many times with tape, when entering a new school.

Your clothes are neat, showing you have good habits, but the style is old-fashioned and obviously ill-fitting, hanging loosely on your body, much too large for your frame. So, I guess they are hand-me-downs from your ‘cousin.’

The old trunk beside you is covered in bumps and wear, the marks of time clearly visible, indicating it has been in service for many years.

Since it's a cousin, your relatives can only be uncles, aunts, or maternal aunts. According to *The Rise and Fall of the Dark Arts* and *Important Magical Events of the Twentieth Century*, your only remaining relatives are your mother's sister, so I deduce you live with your aunt and uncle.

Based on these, it’s easy to infer that they treat you…”

“What did you say? The books mentioned me?”

Harry looked incredulous.

Sherlock stared at him, “It seems you haven’t been reading properly—in fact, I know almost everything about you.”

The look of shock on Harry’s face deepened.

Sherlock gave him a smile:

“Not just those two books. *A History of Magic* by Bathilda Bagshot, a required text for first-year students, also mentions you.”

Harry suddenly felt dizzy.

He steadied himself and couldn’t help but ask, “Then… how did you know Uncle Vernon brought me here today?”

“I was about to get to that—if you hadn’t interrupted me.”

“Oh, sorry.”

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

“It’s fine, just don’t interrupt me again—there’s a mark on the lower right corner of your baggy clothes where it was caught in a car door.

As for why I can tell it was a car door and not something else, it’s because the angle and force of the impact would create different effects. Obviously, this mark was made by the right door of a car.

From your words and the earlier discussion about your attire, it's clear that you are a disciplined person, so you shouldn't have been late today, yet you were.

You couldn't lift the suitcase by yourself, and based on your description of your awful relative, it’s not hard to guess what he did.

He wasn't willing to bring you here, dropping you off at the station just to see you struggle.

For someone visiting for the first time, without keen observation skills, it’s hard to find Platform 9 3/4 between Platform 9 and Platform 10.

I'm sorry, but based on my observations, you don't have that ability, so you could only have arrived here with someone else's help.”

Sherlock spoke very quickly, about twice the normal speed.

Mainly because he felt there was really no need to analyze these things.

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

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

For example, he found Harry as soon as he entered the platform, and also figured out who helped him enter the platform.

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

“That’s amazing!”

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

His appearance made Harry even more admire him.

Harry was about to say something to express his admiration when the compartment door suddenly opened, and a red-haired head poked in.

“Sorry, everywhere else is full, can I come in here?”

Harry immediately looked at Sherlock.

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

“Of course, Mr. Ron Weasley.”

“Thanks.”

The red-haired boy agreed, but after pushing his trunk into the compartment, he suddenly realized something and asked in surprise:

“Wait, how… how do you know who I am?”

“If you want to hide your name,” Sherlock pointed, seeing Harry also looking at him with curiosity, “I suggest you don’t hang a name tag on your trunk, or when you talk to others, don’t face the tag towards them.”

The red-haired boy looked down and was stunned.

He had even forgotten about this.

This person… seems very impressive.

Looking at the red-haired boy's expression, Harry suddenly felt much better.

It wasn't that he was too stupid, but that Sherlock was too amazing.

While Harry was secretly relieved, the boy had already sat down next to Harry.

Mainly because he felt that Sherlock's aura was a bit strong, so he chose the other person.

Compared to Harry, Ron's performance in front of Sherlock wasn't much better, he was also a bit nervous.

In this situation, Sherlock naturally had the absolute initiative.

He was also somewhat interested in Ron.

According to records, the Weasley family is one of the Sacred Twenty-Eight pure-blood families, with a long history in the wizarding world.

Red hair is the iconic feature of their family.

The so-called Sacred Twenty-Eight families refer to wizards or wizarding families who possess pure or nearly pure wizarding blood.

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

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

But from his contact with Harry just now, Harry Potter, who grew up in a normal family, knows even less about the magical world than he does, having read books for a month.

In this case, Ron, who comes from the Weasley family, is a very suitable candidate.

“I’m Sherlock Holmes, just call me Sherlock.”

After introducing himself, Sherlock pointed, “He is Harry Potter.”

After saying this, he stopped.

Because he had already guessed Ron's next reaction.

Ron didn't disappoint him.

“Harry Potter? Wait, you said he's Harry Potter! That Harry Potter?!”

Ron's voice suddenly rose.

He immediately realized that this wasn't good and quickly lowered his voice, looking at Harry in disbelief and asking:

“You’re that Harry Potter?”

Ron stared straight at Harry.

Obviously, the surprise this brought him exceeded Sherlock's deduction of his identity.

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 for Harry: “Obviously.”

This made Harry and Ron both breathe a sigh of relief, and Harry gave Sherlock a grateful look.

“It’s unbelievable, I’m actually in the same compartment as Harry Potter.”

Although he already knew Harry's great influence through books, Ron's performance at this time was the first time Sherlock had seen it confirmed in reality.

This is becoming more and more interesting.

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

Ron widened his eyes in surprise: “This is what the Dark Lord did?”

“Yes,” Harry nodded, “but I don’t remember it.”

Ron eagerly asked again: “Don’t remember anything at all?”

“Well—I only remember a lot of green light, I don’t remember anything else.”

“Green light? What’s that?”

“I don’t know.”

“……”
