Reading Lily's last words in time, Catherine's heart was like overturning all the jars, and she didn't know what was true, and she numbly picked up the second page of the letter, which was very short, just the end of the previous page, but one of the names made the red-haired girl's eyes widen suddenly.

"Catherine! What's wrong with you? Harry couldn't help but want to shake the red-haired girl's shoulders again, only to see that she suddenly connected the two pieces of paper up and down and re-read the last paragraph.

[Bathilda came over a lot, she was an interesting old lady who told a lot of Dumbledore stories, which is really unimaginable.] I don't know if he himself would be happy to hear it! To be honest, I don't know how much to believe, it's hard to believe that Dumbledore will fight Gatler. Grindelwald makes friends. Personally, I think she's a bit confused! 】

"Is there something wrong with this paragraph?" Puzzled, Harry asked, "Do you really believe that Dumbledore and Grindelwald are friends?" He felt it was as unrealistic as Mars could crash into Earth.

"Since the Headmaster is Voldemort's guide to the wizarding world, why can't he be friends with Grindelwald?" Catherine raised an eyebrow and retorted, "You know, the two of them are not two years apart in age. "On top of that, I've seen a picture of Grindelwald who happens to have a pair of dangerous purple eyes.

Catherine had been looking for their owners since she had used illusions to detect the existence of the pair from the headmaster last year, and she had tested Aberforth, but the relationship between the Dumbledore brothers was obviously not as bad as rumored to be, after all, a hundred years later, no matter how big the conflict was, it could not resist the passage of time.

But Catherine really didn't expect that she would find a clue in Lily's last letter in the world, and thinking of this, she couldn't help but read the contents of the letter carefully, and then found a second doubt:

[Locked up here, Jaime is a little depressed. He tried not to show it, but I could tell - the Cloak of Invisibility was still with Dumbledore, so there was no chance to get out. 】

Although the invisibility cloak is relatively rare, as the headmaster of Hogwarts, it is definitely not without it, in this case, why did Dumbledore go out of his way to borrow the invisibility cloak of the Potter family?

"Harry, did you bring back that cloak of invisibility?" Catherine looked up to ask the black-haired boy, but her eyes didn't know where to go.

"Of course!" Harry replied immediately.

"Lend me a look." Catherine put down the letter and photograph, activated the Potter family inheritance ring in her left hand, and quickly searched for information about the invisibility cloak. In the end, nothing came of it.

Seeing Catherine so solemn, Harry hurried upstairs to take off his invisibility cloak.

The invisibility cloak can only hide the body, but not the smell and sound, it is useless for people with keen senses, and the only advantage is that there is no need to worry about the consumption of mana, but because the invisibility cloak is made of the hair of the invisible beast, it will gradually reveal the entity over time. That's why Catherine had ruled it out of her choice early on, so she knew that Harry had an invisibility cloak in her hand, and she didn't think about it.

Since even she knew that the Transfiguration Charm was more practical than the Cloak of Invisibility, Dumbledore, who had more than a hundred years of experience, knew even more about the advantages and disadvantages of both. But he still borrowed the Potter family's invisibility cloak, even for a short time, obviously the Potter family's invisibility cloak was unusual, so that Dumbledore did not care about the safety of the Potter family. Also borrow it for research temporarily.

Harry quickly clutched his invisibility cloak down, it shimmered like a liquid, silver-grey light. It didn't look any different from the other cloaks of invisibility, Harry's body that was blocked by him had lost a trace, and the unblocked body still existed, which looked particularly weird.

The cloak was a Christmas present from Harry's first year, when he and Ron had argued in front of Catherine about who had given it to them, and they had been going back to the dorm room to get the card and ask her to identify who wrote the slender, looped font.

However, when Catherine listened to their description of the handwriting, she dipped some pumpkin juice on the dining table and used her fingernails to imitate Dumbledore's signature on her admission letter, Harry and Ron were stunned and turned to discuss the reason why the Headmaster gave this gift, and naturally forgot to get the card, and now Catherine suspected that the Headmaster had borrowed the Invisibility Cloak from Jaime in the first place, so naturally she could not ignore the contents of the card.

"What was written on the card Professor Dumbledore left when he gave it to you?" Catherine asked Harry seriously, she only wished that the brunette boy wouldn't have such a bad memory that he couldn't remember what was on the card, let alone where he threw it.

"Let me think!" Seeing Catherine so solemn, Harry couldn't help but look down and think about it, but fortunately he was still impressed by this strange gift, so he quickly remembered the contents of the card, "It seems that 'your father left this thing for me before he died.'" It should be returned to you now. Use it well. Merry Christmas from the bottom of my heart! ’”

"From 1981 to now, 12 years, it is still effective after so long." Catherine whispered to herself, and then heard Sirius and Lupin's footsteps.

"Hmmm! Isn't that Jaime's invisibility cloak? It's been a long time since I've seen it. Sirius walked up to Harry, picked up the cloak of invisibility from his godson's hand, and shook it twice with great skill, draping it over himself with ease, hiding his figure.

"Does this invisibility cloak have a long history?" Catherine asked casually in a curious tone.

"Jaime said it was ancestral, and to be honest, I didn't believe it at first, but now I think it's true." Lupin expertly grabbed into the air, and immediately pulled Sirius, who was about to scare his godson, to his side.

"Isn't it made of the fur of the Invisible Beast?" Catherine asked.

"Obviously not. We have been curious to study in many ways, but we have not received any answers, as if it is inherently invisible. Lupin looked meaningfully at Catherine, and Sirius took the opportunity to get rid of him and pounce on the goddaughter, but the red-haired girl only took a small step back, and everyone heard a loud "pound" on the floor, and the soles of their feet felt a violent vibration.

Lupin reluctantly reached out and pulled Sirius up, and Harry's eyes widened for a moment, wondering why he could know where Sirius's arm was.

Sirius saw his godson's surprised appearance, and the frustration that the goddaughter had seen through was suddenly gone, and he was about to scare Harry, but Lupin just knocked his fingers into the air and shouted "stop making trouble" angrily, and Sirius had to touch the back of his head aggrievedly and return the invisibility cloak to Harry.

"It's... You... Remus... How the hell did you spot Sirius? Harry stammered Lupin, not even caring that the Cloak of Invisibility had been taken away by Catherine.

"The smell! Because werewolves have an unusually keen sense of smell. Sirius patted his friend on the shoulder and said helplessly, "When he first started school, he only relied on instinct, and when he was teased by Jaime and me more times, Remus began to try to find us with scent, and now I am as conspicuous to him as a light bulb in the night, whether I wear an invisibility cloak or an illusion charm." ”

"What about you, Catherine?" Harry shifted his surprised gaze to the red-haired girl, "You just stepped back a little and just happened to dodge, is it because of the same reason?" ”

She followed her nose...... Snape learns potions, and his sense of smell is certainly not far behind! Sirius looked at his goddaughter with some sad eyes, "That guy relied on the same method to avoid our stealing ...... every time" Before he could finish his words, he was slapped on the back by Lupin, and after choking on his breath, he realized that what he wanted to say was really detrimental to the glorious image of the "godfather".

"Professor Snape and I have a good sense of smell, but we can't reach the level of Remus, and at most we can only detect anomalies." Catherine looked up and smiled and explained, but Sirius felt in her heart that she was laughing at herself, "The main thing is that my body temperature is relatively low, so if anyone approaches, I will notice it, not to mention that Sirius pounced just now, and the surrounding air flow was completely disturbed by him, so I can naturally sense his position lightly." ”

Harry's mouth was wide open, Lupin gave him a shocked look, and Sirius leaned over to Catherine, bending down to examine her as if she were a treasure.

Catherine was so uncomfortable with him that she threw the cloak of invisibility on top of Sirius's head, and the cloak unfurled in the wind, covering Sirius like flowing water, but because it was in the opposite direction, instead of hiding his figure, it kept shining with a silver-gray light.

Sirius hung her shoulders in frustration, causing a smile to tuck into Catherine's mouth, but then her expression froze as she suddenly noticed that there seemed to be some patterns inside the cloak.

"Don't move!" Catherine shouted to stop Sirius from trying to remove the cloak of invisibility from her head, moving her head, struggling to discern the patterns on it, and Sirius, who didn't know what was going on, had to maintain an unusually strange posture with difficulty.

"You can't see it clearly." Lupin smiled and pulled the Cloak off his friend, relieving Sirius of his embarrassment, and shoved one side of the Cloak into his hand, "You'll have to level it to see the pattern on it." ”

Sirius understood what Catherine wanted to see as soon as he heard his friend's words, and immediately took two steps back with Lupin, completely spreading the cloak of invisibility and straightening it.

"It's really patterned!" Harry shifted his perspective around for a moment, and soon noticed the anomaly in the silver-gray light, "What's the drawing on it?" (To be continued......)
