Chapter 11: Checkmate

'So you say that Snape has told Dumbledore everything?' Cain asked Ciel thoughtfully. They were standing in his apartment, together with Sebastian, moments before the good-bye feast was supposed to start.

'Yes, Sebastian was spying on him,' Ciel confirmed. 'Dumbledore knows that you're a Deatheater, that you have made a plan to deliver Potter to the Dark Lord and that you have asked the Dark Lord to come tonight to the Forbidden forest.'

'That certainly makes things more difficult,' Cain said. He underestimated the treachery of Snape.

'It just means you can't go there,' Ciel pointed out calmly. 'It is of no consequence for me and, if you stay with the teachers all the time they will have no proof that you were involved.'

'I believe the other teachers would rather trust their headmaster than me. And what do you mean they will have no proof?'

'Sebastian could remove it before,' Ciel said and raised his hand when Cain was about to speak. 'I know the Dark Lord will know, but I will already be on my way with Potter and then he will not think about you until it's too late. And as for Dumbledore – they have no proof, just their words.'

'Your father didn't have the tattoo,' Cain pointed out. 'That creates a precedence and will be enough for them.'

'But do they know that he didn't?'

'I'll humour you for a moment. What do you want to do?' Cain asked and Ciel led him, step by step through the whole sequence that he made up.

'My Lord, we should start before Potter arrives to the Great Hall,' Sebastian said suddenly. 'The time for the feast is nearing and if the professor doesn't join the other teachers they will get immediately suspicious.'

'Do it then,' Cain said curtly. 'If that is how you see it.'

'I will die anyway tonight,' Ciel pointed out. 'You don't have to. My grandfather and aunt will be sad enough with my death, there is no reason to sacrifice you as well.'

'You might want to put a powerful silencing spell on this room, professor,' Sebastian said with a bow. Cain complied and the demon-butler asked him to pull up his left sleeve.

When it was done, the demon put his hand to the skin. An explosion of light and pain blinded him and he couldn't stop the scream that tore itself out of his throat.

He collapsed when the demon took his hand away and would have fallen to the floor if the demon hadn't been there to catch him and seat him in one of the armchairs, where he stayed for a while, panting in pain.

'I'm afraid there was no other way,' Sebastian said, but Cain was busy looking at his left forearm – without the threatening tattoo for the first time in many years. Just the scars from his clumsy heal charm remained. He shook his head to clear the thoughts and looked at Ciel.

'You don't have much time left,' he stated, pain audible in his voice. 'I will remove all the protection spells from Potter in five minutes. Then I will join the teachers and pretend nothing happened. If you don't manage-'

'I will manage,' Ciel said. 'Thank you for your help and good luck,' he added and left the room. Realizing that it was the last time he saw the boy alive, Cain pursed his lips.

Nevertheless, he counted off five minutes and muttered the spell that stripped Harry Potter from all the magical protection that Dumbledore had woven around the boy over the years.

Just like that. Potter was defenceless and Cain needed to hurry to the Great Hall to create his alibi. Without hesitation, he went to join the other teachers, smiling smugly at Snape's narrowed eyes. Dumbledore seemed surprised to see him and Cain almost laughed – it would give them some thinking until they know the truth.

'Well then, the students should arrive soon,' Dumbledore said finally. Cain hoped that somebody has seen Potter after that moment. While the wizards kept no videos or transcripts that could prove him guilty, which made it easier than working with Muggles, he would be happier if there was no doubt that he hadn't deposited Potter away before joining the other teachers.

Hermione ran into the Great Hall, making straight for the headmaster, shouting for him. All the teachers and the few students who have already arrived looked at her.

'Hermione? Is everything alright?' Dumbledore asked, making Cain roll his eyes. He had a good feeling of what was wrong, but he tried to look convincingly worried.

'It's Harry, Professor,' she almost sobbed. 'We were going to the Great Hall when he suddenly stopped and turned to go somewhere else!'

'What?' McGonagall exclaimed. Cain felt a tip of a wand dig into his back and he automatically straightened a bit more.

'He didn't react to anything we said and he cursed Ron, when we tried to stop him and he was going to curse me as well but I ducked,' Hermione said breathlessly.

Much to the surprise of everybody gathered in the room, except for Cain, Dumbledore turned to face him.

'Your game is over. Where is Harry?' he asked angrily and the wand dug deeper into his back, to the point of actually hurting.

'How should I know?' he asked, mixing confusion and a bit of fear into his voice. It was indeed quite a gamble that he was doing.

'You can stop your game, I know everything,' Dumbledore said quietly, so that only Cain heard him. 'I know you're a Deatheater and a spy.'

'What?' Cain exclaimed in a hopefully convincing act, then he yelled a bit and jumped away from the wand that was threatening to make a hole in him.

'Roll up your sleeve, Deatheater,' Snape growled.

'Which one?' Cain asked innocently and ducked when Snape tried to punch him with a roar. 'Shouldn't we be looking for Potter?' he added with the same, innocent tone. 'As a Defence Against the Dark Arts teacher I would like to say that this sounds awfully like Imperius Curse.' Snape tore off his left sleeve and stared at three long and thin scars that ran along the forearm.

'Thank you,' Cain said with annoyance. 'Now I have to get another suit and shirt.'

'What is the meaning of this, Severus?' Dumbledore asked.

'Albus, we should find Potter,' McGonagall, who must have been very confused at that point, although it was obvious what Snape and Dumbledore were thinking about him, interjected.

'Call all the members of the Order,' Dumbledore shouted, as though waking up from a dream. 'Search the castle! You!' Dumbledore turned to him. 'Stay with Severus and me at all times.'

'As you wish, headmaster. Although please forgive me if I can't quite run to my top speed yet,' he added just as the members of the Order of the Phoenix rushed into the room.

Oh how he wished to kill Black, he thought but knew that he needed to restrain himself. This revenge would have to wait till later.

Dumbledore put them into teams and rushed out to search the castle himself, Cain barely managing to follow.

Voldemort felt as though somebody stabbed him – a Deatheater died. Was this Cain and was this whole thing a trap? – he wondered. He had been often warned that Severus was a traitor and that he should be careful – should he have listened to those voices?

He would have started pacing if not for the fact that there were two Deatheaters with him. Severus said "it's safe, you don't have to bring an army and less people will be less noticeable" – was it a trap? With a motion he called one of the Deatheaters and touched his wand to the tattoo. Everybody should come now – if it was a trap Severus was going down.

Just as the Deatheaters started arriving, forming a circle around him, two figures walked in from between the trees. Both looked like they were students and Voldemort ordered the Deatheaters to leave when he realized that it was none other than Ciel Phantomhive, his wand pointed at Harry Potter, who walked towards his nemesis with an empty look on his face.

By the time they reached him, it was just the three of them, Nagini and a black cat.

'Ciel Phantomhive,' Voldemort said with a slow smile.

'Dark Lord,' Ciel replied with the tiniest of bows. 'I believe that you desired this student,' he added coldly and Voldemort laughed.

'I can't believe that Cain had sent Vincent's son to meet me!' he exclaimed. 'Ingenious really. That way he skips all suspicion!' Ciel looked at him emotionlessly and so Voldemort, a bit unsettled, turned his attention to Potter.

'Undo the spell,' he ordered and Potter's eyes focused. He first saw Ciel but before he could ask what was happening, he noticed Voldemort and stumbled away. Ciel watched him without emotion and he opened his mouth to say something, but words never left his lips.

'The hero of the world. Speechless,' Voldemort goaded and laughed. 'Finally at my mercy!'

'Just kill him,' Ciel ordered coldly, shocking both Voldemort and Potter. 'I want to talk with you and we don't have forever before somebody goes looking for that annoying kid.'

'Well, well, Earl Phantomhive,' Voldemort hissed. 'You are certainly impatient, but you should know that I don't take orders from anybody,' his voice took a threatening tone, but the boy just glared at him with his only visible eye. Amazed that somebody stood ground against him, Voldemort suddenly decided that he indeed wanted to talk with that amazing boy who was not afraid of him and, offhandedly, cast a killing curse at Potter.

As his fellow student collapsed on the ground, a small smile graced Ciel's lips.

'Did you order my parents murdered?' Ciel asked and Voldemort's eyes widened a fraction. Then he smiled.

'So you have found that out, haven't you?' he purred. 'Such a smart boy you are. You will surely make a fine Deatheater one day. I'm glad Cain sent you here.'

'Nobody sent me here,' Ciel said coldly and pulled off his eye-patch. Voldemort saw the seal of a contract and took a step back.

'You have contracted my demon!' he hissed, finally realizing what happened that bloody night when he lost twenty of his best Deatheaters.

'Your demon?' Ciel asked mockingly. 'If anything it would have been Malfoy's demon because you were too much of a coward to do it yourself.'

'Watch it, boy,' Voldemort hissed. 'I don't have endless patience, even for such promising Deatheaters.'

'Sebastian,' Ciel called coldly. The butler stepped out of the shadows to the side, carrying the dead snake.

'Nagini!' Voldemort exclaimed in distress, suddenly realizing what was happening. 'You took the cup from the vault!'

'I have found out about your Horcruxes. They are all gone now and it's only you and the demon,' Ciel said emotionlessly. 'Kill him Sebastian.'

'Yes, my Lord,' the butler bowed.

'Checkmate,' said Ciel and then Voldemort didn't hear anything anymore.
