To Sakura Lisel: Because Voldemort is stupid. He's not going to go through the whole thing of 'killing himself' and have to find someone to bring him back. And I'm not going to have him do that. Don't worry, he'll get finished off.

Chapter Seven

As it got closer to the Full Moon Harry started to feel the effects. Severus brewed the Wolfbane Potion and he drank it down, almost throwing up. However he was rewarded with something sweet when he finished. If it hadn't been for that he would have given up.

"You'll be glad that you drank that next week," he said.

Harry was sure that he would but he just couldn't vision it every day that he drank that horrible potion. Lupin also got the potion as well, remarking that it tasted better than the last batch.

"Do you think something happened to it," Harry wondered.

"I don't know, but anything is possible."

The one main feature that the hotel had was a room that Harry could go into when he needed to transform. Severus had explained that French Wizarding laws were different than in England. As long as the werewolf was under the Wolfbane potion then they were fine. Harry sent his present to Hermione by Hedwig. He really hoped that Hermione liked it.

"Alright, Harry, the moon will be rising," Severus told him.

"Thanks for reminding me," Harry muttered.

"When your back to normal we'll get you healed."

Harry nodded and followed Severus to the part of the hotel that was for their werewolf guests. He shed his clothes and gave them to his father. The door closed and sealed, leaving Harry alone to transform. The moon appeared quickly and Harry felt the first signs of the change. He screamed as hair formed all over him, his bones broke, extended, and came together. His face changed, growing, and taking the form of the wolf. His nails grew into claws and then it was over.

The howl of a wolf broke through the silence outside of Malfoy manor. Narcissa shook with fear, holding Draco.

"Mother, nothing is going to come and hurt us."

"I know dear, but I'm worried."

The Death Eaters, wearing regular clothes, were watching for any sign of their former master now turned into a blood craving monster. They were armed with the only thing that they had; their magic. If he attacked they would use the Killing Curse, which was legal to use on a werewolf. They all agreed that their former master would attack the Malfoy's first. They were proud of being purebloods and would hate being attacked, infected, or killed.

Also they were all wanted by the Ministry.

"Honey, why don't you head to bed," Narcissa said. "Morning will come and this nightmare will be over."

"Yes, mother," Draco said and he headed to bed.

An hour later the Death Eaters, Lucius, and Narcissa heard a scream and Narcissa bolted, heading for Draco's room. She forced it open and found her son covered in blood, but alive. Narcissa screamed and then she heard a growl. She turned and the wolf attacked. She managed to slice it across the muzzle but it bit her in the arm. She passed out.

"Kill it," McNair ordered.

The wolf had gone through the open window and landed on the ground. The Death Eaters went after it but vanished into the bushes.

"Let's follow the blood."

"And get caught by the Ministry," Lucius said, "I need to get my wife and son help."

"The only thing that you can do is kill them," McNair said. "If that was Voldemort then he's done his damage."

"No, I'm not killing them."

"Then I will."

Lucius grabbed him and said, "If you kill them, so help me I will kill you."

"You're a fool!" he said.

Lucius said nothing.

He had a house elf take Narcissa and Draco to St. Mungo. Everything shattered around him and he couldn't think. His line had been forever tainted and it was all Voldemort's fault. Now he knew what others had felt and he vowed that he would hunt Voldemort's source of immortality and destroy them. It was time to seek help from Dumbledore.

When Severus fetched his son he found his son covered in blood. Since no animal had been with him he had attacked himself. He was led to his room where Madam Pomfrey cleaned him up and put him to bed.

"Severus there was an attack on Malfoy's Manor," she told him.

"WHAT!"

"The Ministry believes that it was a werewolf," she said. "Dear Merlin, what's going on here?"

"It was either Greyback for Tom," Severus told her. "Since Greyback likes to attack the young then it could only be Tom's handy work."

"But he can't drink the Wolfbane until his first transformation is over."

"I know that, but he might of found something that allowed him to keep his mind," Severus reasoned. "He's had a full month to figure out what to do."

"So someone helped him."

"Someone was most likely force to help him," Severus corrected. "Harry is going with me to Italy once he's recovered."

"Do you think that Lucius will seek Dumbledore's help?"

"Most likely," Severus said. "Something was taken from him and he'll do the same thing that I did."

"Do you think that Albus will help him?'

"I think that he might," Severus stated.

Three days later Severus and Harry took another Portkey to Italy. Dumbledore watched them leave and then took one himself, back to Hogwarts. When he arrived he found Lucius Malfoy waiting on him.

"You're a wanted man, Lucius," he said.

"I don't care," he said to him, "I need your help."

"And what is it that you need?"

"Have you ever heard of a Horcrux?" he asked Dumbledore and Dumbledore gave him a look that told Lucius that he had.

"Why are you asking this?"

"Because I want to join in finding them," he said, "I know that you had no clue how Tom manage to return back to physical form. But I know that it was due to him splitting his soul."

"That would explain how he didn't die," Dumbledore reasoned. "Lucius are you doing this because of what happened."

"When that monster infected my wife and son he lost any support that I have," Lucius said, "I might not like muggleborns in our world but I can ignore that as long as Tom doesn't ruin anymore people's lives."

"You understand that you will be ensuring that muggleborns can come into our world."

"Yes, I understand," he said.

"Well then, let's see what a diary can show us."

A/N: This is shorter than my other six chapters but I thought this was a good place to end the chapter.
