Ivan nodded at Dumbledore's words.
Even a Master Alchemist like Voldemort could not be 100% certain that the Isolation Space would be able to evade detection by the Marauder's Map without first seeing the object.
So Voldemort must have found something in Peter Pettigrew's memory.
"By the way, Professor, how did you and Hermione get past the Marauder's Map, or were you in the Chamber of Secrets before I arrived?" Yvonne asked curiously.
Dumbledore had no intention of hiding anything and immediately explained.
"Last year, at the end of school, I asked Sirius about the Marauder's Map, and he told me about a very interesting name spell he had used on it, and it took me some time to decipher it and find a way to hide the name."
"Actually, we were following you around this evening…but Professor Dumbledore was afraid of being seen through by Professor Moody's magical eye, so he didn't get too close," Hermione added.
Ivan's mouth twitched. He had been so focused on tracking Moody's movements that he had not expected to be followed.
Ivan is not surprised that Dumbledore has broken the spell on the Marauder's Map.
At the end of the day, it was only a slightly more powerful magical object, and with the crucial information provided by the founder Sirius, it was naturally not difficult for a Master of Magic like Dumbledore to obtain.
He even suspected that Lord Voldemort could also create a charm that temporarily blocked the Marauder's Map, but Barty Junior's powers were not strong enough to perform the spell, or rather, could not be used.
After all, a Moody without a name is just as suspicious, and unless Voldemort could find a way to change it, it would be more reliable to control the True Moody with the Imperius Curse.
"Well, I don't think this is the time to discuss it." Dumbledore ended the conversation and turned to Moody. "Alastor, you have not told us exactly what Voldemort's plan is…"
"Voldemort needs me to bring Harry to him," Moody said.
"Through this Triwizard Cup?" Dumbledore asked again.
"That's right!" Moody nodded. "Buddy Junior ordered me to change the rules of the tournament by casting a Confunding Charm on the Goblet of Fire, increasing the number of students allowed to attend the tournament to four, and only one student from the fourth school will be allowed to attend, thus ensuring Harry's place as a champion!"
"But how are you going to get Harry to You-Know-Who?" Hermione was baffled; she had assumed that You-Know-Who intended to use the dragons and merpeople to get rid of Harry.
Moody went on to explain: "By the time of the third match, the champions would have entered a maze in search of the Triwizard Cup, and Barty Junior was planning to swap the Cup for a Portkey, thereby bypassing Hogwarts' protective spells."
"And it'll be in the middle of a match, so we won't have to worry about anyone following us by magic for a while…"
"All I have to do is somehow get Harry to win this game and get the Portkey first!"
Moody went on and on, his mouth dry as he grabbed a glass of water and gulped it down, waiting for Ivan, Hermione and Dumbledore to digest the information.
"Then they must not have expected him to take part, and given the results of the first two matches, Harry's chances of winning were slim, so I assume you changed your plans along the way?" Dumbledore asked thoughtfully.
"That's right, much to Barty's surprise, as underage wizards are banned from the Triwizard Cup. Fortunately, Harry was in second place, so it was easy to get rid of him." Moody gave Ivan a pointed look.
"No wonder you said you'd lure me here sooner or later," Ivan muttered.
There was just one thing that Ivan found strange. Barty Junior was obviously prepared to die with him, but who would complete Voldemort's mission if he died?
Yvonne voiced her doubt curiously.
"I don't know about that," Moody said, shaking his head.
"But Barty Junior could have lured you there the day before the match, so he could have placed the Portkey in the maze first, and even if he had died, Harry would have had a good chance of winning."
Yvonne thought about it for a moment and decided that it made sense. The Goblet of Fire was special, and it had happened so suddenly that even if she disappeared on the day of the match, the match would have to go on.
As for the risks involved… changing the plan at the last minute was always risky.
"By the way, Professor Moody, I have one last question. If you were under the influence of Barty Junior's Imperius Curse, why did you bring me along to investigate the case and expose Mr Crouch?" Yvonne asked.
"To allay your suspicions of me, of course." Moody raised his eyebrows and stared at Ivan for a long time. When Ivan became uncomfortable with the question, he continued.
"I must say, you are incredibly sharp, Hals! Barty Junior kept me hidden from everyone at Hogwarts, even from Albus, except you! You suspected me the first time we met, didn't you?"
Hearing this, Dumbledore and Hermione both turned to look at Ivan, equally puzzled.
Under everyone's gaze, Ivan shrugged and replied freely.
"I think I've explained to you, Professor, that it was because of the previous Defence Against the Dark Arts professors that I suspected you. Also, I was curious as to why you were wandering around in the middle of the night on the first day of school."
Moody nodded and realised that on the night of the first day of school, he had indeed gone to the kitchen to ask the house-elves to prepare a meal for Barty Crouch Junior, presumably because Ivan was up at night and happened to be looking at the Marauder's Map.
"No wonder you came out to follow me the other night," Moody muttered. "Buddy here figured you'd found a clue, so he asked me to draw your attention to Crouch so he could give you something to do."
Wait, was there such a thing? Yvonne was baffled. When had he followed Moody, except tonight?
