Chapter 1:

"Inform me again Albus, why you need me to stay at Potters through the summer holidays. I have more important things to do than teach that little brat & his cousin stupid muggle lessons?" Severus asked, irritated by the man he had considered his father since the day he had accepted him being a spy for the light.

"Well my boy, I need someone to keep an eye on Harry seeing as now Voldemort is getting stronger each day, someone needs to be there with him if death eaters try to attack the house at any point. Besides you're the only one who isn't busy this holiday." the headmaster replied. This was the second time he had tried to persuade Snape to become the Dursley's muggle tutor.

"You're going to pay for this Albus. When I agreed to be a spy I don't remember signing up to be some muggle tutor to look after your precious Potter." Dumbledore knows that Snape had despised the boy ever since he seen him at the sorting. All he could think was that he is a double of his father. "And don't think this means I will start to like the boy, Potter is just as worse as his father." Scowling at the man in front of him.

Dumbledore's blue eyes started twinkling behind his half-moon glasses, a small smile creeping onto his face behind his long white beard. "I knew you would agree Severus. Right you will be arriving at privet drive tomorrow at 12. You will be known as a muggle named Craig Thomas, I will need to change your appearance before you go, we don't want Harry to know it's you. I also want you to be nice or at least polite to the boy, after all he has lost his godfather under a month ago."

Severus grunted in reply with a scowl imbedded across his face, looking towards Albus he nodded before leaving his office with a swish of his black robes and making his way back to his room.

Severus Snape was one of the most hated professors to walk through Hogwarts corridors. Students referred him as 'the bat of the dungeon'. He wasn't an attractive man either. Always wore plain black robes, pale skin like a vampire, dark greasy curtains of hair hanging both sides of his face, a crooked nose which was so big it nearly reached over his lips which were permanently set in a scowl and a pair of deep black orbs, always looking lifeless as is he has never seen happiness.

Only one person ever gave Severus happiness. Lily Evans. Lily helped Severus through his hard times during Hogwarts until he accidently called her a mudblood. From then on Severus began to hate himself and Lily never gave Severus her friendship again. That day lost Severus his best friend and his love. After when they finished school, Lily married James potter, the one that made Severus's life a living hell during Hogwarts. They both had a son, Harry Potter who a year later managed to survive the killing curse whilst his parents were killed by Lord Voldemort. This was where the potions master was off to tomorrow. To baby sit potter disguised as a muggle.

Snape arrived outside his quarters and whispered the password to the portrait. His rooms were decorated in Slytherin green and black. He made his way to his bedroom and started packing clothes for his stay at Privet drive. He didn't own any muggle clothing so he had to transfigure all of his clothes into male muggle ware; he of course kept everything dark.

With his bag packed he decided to spend his last night of freedom alone. He settled on his sofa with a potions journal and a glass of firewhiskey, he didn't pay full attention to what he was reading as his mind was wondering to what tomorrow and the rest of his 5 weeks were going to be like. A living hell.

To everyone in the street, number 4 privet drive on the outside seemed an ordinary house. Mrs Dursley was a horse faced woman who was a very nosey neighbour, she needed to know everything which was happening around her but herself was a privet woman. Her husband Mr Dursley was a large beefy man who managed a drill company and her son Dudley was the same built as her husband and was known as the neighbourhood bully. Not many people outside the house knew of Harry potter, nephew of Mr & Mrs Dursley as he was not considered normal. It was not every day you came across a real witch or wizard who could do magic.

"BOY!" Vernon Dursley bellowed up the stairs. "Get down here this instant."

Harry nervously carried his bruised body of his broken down bed and made his way down the stairs into the front room to face his uncle.

Vernon made his way over to the boy and harry wrapped his arms around himself protectively. His uncle grabbed both of Harrys arms painfully and pushed him against the opposite wall, up to Vernon's height so he was looking him square in the eyes.

"You listen here boy, over the next 5 weeks we are having company over. This person is going to give both you & Dudley private maths & English lessons, I am warning you now boy, anything freaky happening whilst he is around you would of hoped your hopeless parents never gave birth to you" harry whimpered as Vernon started to shake him violently to try and get the message into him "You will treat this person with respect and if I found out you have disrespected him you will have no food for a week. I want you now to clear out your room and move it under the stairs, whilst he's here your back under there and you will be cooking and doing chores like you usually do, just because he is here nothing if going to change." Vernon dropped Harry to the ground and kicked him once in the stomach and turned away back into the kitchen.

Harry knew not to make a noise as he made his way back into the room. He silently lifted up the broken floor board and took out his most prized items. He looked around for the bruising balm he 'stole' from the hospital wing in Hogwarts last year. The balm never got rid of all the bruising but it was enough to not notice far away.

Taking out the other items he came across a piece the mirror him and Sirius Black, Harrys godfather used to communicate through. Sirius died just under a month ago because of his fault, when Snape gave Harry occlumency lessons Harry knew he should of blocked Voldemort out of his head, if he did manage to Sirius would still be alive, harry cannot help think that it was all his fault. Harry stared at the mirror for a few more seconds deciding whether to do something or not.

Biting his lip he picked up the mirror and sat on the creaky old bed in his room, rolling up the sleeve to his overly large jumper he gently placed the sharp end of the mirror to his scarred wrist. He lightly traced the healed scars up and down his arm before starting at the bottom again and dug the mirror deeply into his wrist until he saw a drop of oozing red blood come out between the mirror and his skin. Only then harry started to breathe again, gasping when the mirror came in contact to his wrist.
