As for the others, the SG team was distracted by Catherine's two new unexpected missions, and almost didn't even care about their normal lives, let alone remembered Siris hiding in that dark place. Black.

The rest of the students were also a little absent-minded by them, with the exception of the fifth and seventh graders, who had a heavy exam this year, and every professor was asking them to hurry up and revise for it.

For this reason, Dumbledore specially convened a meeting of the teachers, and then arranged special review classes every evening and Saturday and Sunday. There are a total of 12 courses at Hogwarts, and N.E.Ws and L.E.Ws have different exam requirements, so in order to ensure that interested students can attend, even if each class is compressed to one hour, it can only be repeated three times a month.

As a result, every professor had to rack their brains to find a way to tell more in an hour. Other professors are fine, even if they don't say well in the special review class, by the time they reach the fifth and seventh grades, the students have a year to listen carefully, but the DA class is an exception.

No one thought that Lupin would be able to teach for another year, and even Dumbledore had already begun to secretly look for a professor of next year's DA class just in case, so in order to ensure the level of the students, the DA special review class was arranged the most, and even when other professors were unable to attend the special review class, the time would be handed over to Lupin to arrange.

So Lupin had to put down the special review class on an equal footing with the normal class, and carefully arrange the content of the class, because his class was so popular that the number of people had to sit in the auditorium, even the Slytherin, who had the most opinion of him, never missed it, and even Quidditch training had to obediently give way.

On September 19th, Hermione's birthday, the SG team hosted a birthday party for Catherine. So that this brown-haired girl, who has been unusually busy recently, can relax, but in the end, she almost broke up.

The reason is that Ron saw that Banban had been locked up in that pet house by himself recently, so he decided to take the opportunity to take it out to breathe, and by the way to see if he could get along with Crookshan, but he was only a little negligent, and the hateful cat bit Banban and quickly rushed towards the door.

Ron screamed in fright, but luckily Catherine closed the doors and windows with magic in time, and the others hurriedly helped, but Crookshank was too flexible. It took a lot of effort for a group of people to save Banban from the cat's mouth.

As soon as Ron got his frightened pet back, he left immediately, but before leaving, he scolded Hermione a few words, which completely made the little birthday star cry, and everyone had to comfort her, but they couldn't make her regain her joy until Lupin, who was late, gave her DA notes from her school days, and completely diverted her attention.

But after Lupin heard what had just happened, he suddenly asked about Banban's appearance with a strange face. Then she made an excuse to leave beforehand, and seeing this, Catherine also quietly added a confusion charm to herself, and followed in the footsteps of Professor DA. It wasn't until he suddenly stopped at the intersection and didn't know where to go first.

"Maybe you need this." Catherine pulls out the map of the living spot that has not yet been revealed, and hands it to Lupin.

"That's right! That's right! Lupin turned and glanced at the piece of paper, smiling and holding out his hand. But then the outstretched hand stopped in mid-air, "How do you know?" ”

"That note, you shouldn't have compiled it alone. I noticed the handwriting of four people. Catherine smiled as she explained, holding the map but not retracting it, "Coincidentally, I often see these four handwritten graffiti on library books, and their signatures happen to be Wormtail, Moony, Padfoot, and Prongs, so I tested that if you were one of the members of Marauder, you wouldn't be able to forget your proudest work." ”

"Even though I've always been used to being modest, I have to agree with you this time." Lupin took the map of the living spot and gently stroked its old appearance, "It's just that I didn't expect it to be in your hands." , I thought it had been confiscated by Feige. ”

"Your successor is deciding to put it back to its 'right' purpose." Catherine opened a secret room in snake language and led the way inside, "They are as curious as I am about who the maker is?" ”

"Then don't let them know the answer!" Lupin, who followed Catherine into the secret room, suddenly felt a headache when he thought of the twins' elves and eccentricity, as if he had seen his two friends.

"But what I'm more curious about now is the origin of these four names!" Catherine frowned suddenly, "If they're crazier than their successors, then I have no doubt they'll do that kind of thing." ”

Lupin was stunned for a moment, and said with a wry smile: "So far, I have been hesitating whether to sue Sù Dumbledore, but I didn't expect you to guess it first, it seems that I have once again betrayed Dumbledore's trust in me." He hung his head helplessly and tugged at the parchment in his hand.

"I don't think it's time to sue the principal, because we don't have enough evidence to prove his innocence, although I'd love to ask right away why he went into hiding for 12 years!" Catherine's voice was soft, but her tone was unusually firm.

"Do you want him to confront him face to face?" Lupin asked in surprise, apparently knowing who the two he was referring to.

"yes, so you have to find him first, and he's a very good bait." Catherine tapped her fingertips on the dot map, "Now my only doubt is, what kind of animal is Padfoot referring to?" ”

"Dog!" Lupin looked out the window and recalled, "A very huge dog, with teeth an inch long, and shiny black fur!" ”

"It's really a 'big foot'! And what about the Prongs? Catherine asked curiously.

"Stag!" Lupin smiled and looked at Catherine, "Like Harry's Patronus. ”

But Catherine's face suddenly became unusually strange.

"What's wrong?" Lupin asked, puzzled.

But Catherine did not answer, but asked another question: "I heard that the beating willow tree was planted in 1971, and you happened to enter school that year, so can I think that it was specially prepared for you?" ”

"Yes, just hold down one of the knots on it and it will stop dancing." Lupin walked to the window and pointed to the beating willow tree stretching below, explaining to Catherine, "It's usually Wormtail's job because he's small enough, but you don't have to worry about it." The bitterness on Professor DA's face turned into an awkward smile, "Dumbledore, Madam Pomfrey, Professor Sprout, and Severus all know the secret passage underneath it, so it's impossible for Bigfoot to get in from there." ”

"And which one is behind the hunchbacked one-eyed witch on the fourth floor?"

"After Dumbledore told me the purpose of asking me to be Professor DA, I told him the entrance and exit of the secret passage." Lu Ping frowned slightly and said, "He has made some arrangements, but he has not achieved anything so far." ”

"So the only place he can enter Hogwarts is the gate?"

"Dementors are always guarding there."

"If he could slip out of Azkaban under the noses of the Dementors, why couldn't he sneak into Hogwarts under their noses? Fudge sent them to see the door just to save the Ministry of Magic's already tattered face! ”

Catherine was clearly obsessed with her magical riot, otherwise she wouldn't have even given Fudge the honorific title she deserved.

"So, he's really already at Hogwarts!" Lupin couldn't help but frown.

"He won't venture into the castle because he doesn't know who the map is, and he won't reveal his whereabouts until he finds an opportunity, so he'll just hide in the Forbidden Forest, which is out of the map's reach."

"Find a black dog in the Forbidden Forest, it will definitely startle the snake." Lupin tapped on the parchment and said, "How are we going to lure him into the castle?" ”

"Just stop Crook Mountain." Catherine smiled brightly, "Ordinary cats will definitely swallow a mouse in one bite, but Crookshank Hill has been just playing around since he met Banban last year, and apparently he knows exactly what Banban is?" The only thing we had to do was improve the map before he ran into the castle so that it would show the location of the person we were looking for in the first place. ”

"You're right." Lupin slapped the map vigorously, "I'll go to the library to look for it later, the materials I borrowed when I first made the zuò, after all, the 'main force' at that time was the pointed fork and the big foot, I really have to remember it well, in order to figure out the principle of this map, I'll contact you later, as for this map-"

"Let me go here first!" Catherine did not hesitate to retrieve them, "lest you suddenly run to them and cause me to waste all my efforts." ”

Lupin touched his nose embarrassedly, but did not say anything to refute it.

"I'll go back first, so that no one else will be suspicious." Catherine put away the map and left the chamber, "I'll be notified if there's something happening." ”

Lupin didn't leave, but stood in front of the window, looking at the beating willow tree who was fighting with the ignorant first-year student on the grass for a long time, until it was dark, and then turned to leave the secret room.

Adjusted to the new semester's curriculum and arranged to deal with Sirius. Blake's plan, Catherine immediately turned her attention back to her goal, and went to talk to Percy as Ixissi wanted.

Percy and Ixissi, although they are rivals, have different career paths, Percy is targeting the Ministry of Magic, and Ixissius is preparing to join the Wizengamot, but interestingly, although the two organizations are different in nature, they need to learn the same curriculum.
