"Do you think that we have been sent here to take care of Grindelwald ? He is the only active Dark Lord I can think of around this time." Sirius said while looking around muggle London.
"Maybe you're right. Maybe he inspired our snake faced Dark Lord to become whatever he become." Harry replied nodding her head.
Sirius stared at Harry in confusion, "How?"
"Oh ,Voldemort is in school now. I remember that diary Riddle said that he attended Hogwarts fifty years back. Maybe..." Then Harry stopped. She looked back at Sirius. " Siri I just realised .. maybe we have been sent here to stop teenage Voldy from becoming Dark Lord. We will change fates of so many if there won't be any Voldemort. I won't be a boy-who-lived. My parents.."
"would be alive", Sirius finished his sentence excitedly. Then he started laughing "I won't go to Azkaban. Prongs would be there. I might start my own family as well. Oh Harry.. this is amazing. Everyone would be happy. We'll change lives."
Then both started laughing holding their hand. People passing by looked at them strangely.
"Come on Harry, we've lives to change. Let's begin our mission with Diagon Alley. We've research to do. Follow me." Sirius said with his head held high. He marched towards Leaky Cauldron with Harry in tow.
They entered Leaky Cauldron. Harry noticed that it looked similar to their time, somethings never change. However, Tom looked quite young.
They took a table at the back. Sirius started drumming his finger on the table, then looked at Harry who was seated across him. "So...For this mission we first need to do thorough research of our target. Tell me what all do know about Voldemort's background?"
Harry shrugged and said, "Not much. Just the bits he himself told me about himself. He is an orphan, half blood like me. His mother was a witch and father a muggle. He is in Slytherin house also a Slytherin heir. That's it... Oh and one more thing, his full name is Tom Marvolo Riddle, which anagrams to 'I am Lord Voldemort'. He already have few followers in Slytherin who know this name."
"Hmm.. so that means we don't know much. I don't know anything about his background as it was never publicised. I don't think many even know his real name, given they are scared to say his anagram name." Sirius finished. He looked towards the wizard who just entered, then back at Harry. "I think we'll begin our mission by getting admission in Hogwarts. Voldemort would be there."
Harry thought about it, then nodded, "We'll be needing background story and money for that. I am not carrying any Galleons and I don't think you have any with you. We are basically bankrupt right now."
"You're right. First we need to arrange money. Also we need to look for some place to live till school starts." Sirius started thinking about the way to earn money.
"We could buy magical tent and camp somewhere. We can find a work for money." Harry suggested.
Sirius shook his heads, "We won't be able to earn enough in less than a month for buying Hogwarts stuff. There is one more option. We can forget about morals, and steal muggle money then convert that money into galleons. With magic we can try few tricks to steal it from them. I can't suggest stealing from wizards as we would be easily caught in magical world."
Harry thought about it, and agreed with Sirius that they can't think about morals. They had very few days to do all arrangements for Hogwarts admission. She didn't know where Riddle would be after Hogwarts or during holidays. The only way they can stop Riddle was by going to Hogwarts with him. "You're right. But Siri there is one problem..I won't be able to do magic. Age restriction."
At this Sirius started smiling and said, "That's the best part Harry. You can use your wand here. You are not born yet so no age restriction problem for you. If you forgot, you did magic today to conjure mirror and there was no ministry owl."
Harry started smiling as well, loving every second spent in the year 1943.
After a lot of discussion and planning, both Sirius and Harry were standing at an alley's entrance near a muggle jewellery shop. They were under disillusionment as well as notice-me-not charm. They were looking for some rich muggle target to steal money from. After few minutes, a fat lady in a frilly dress carrying a glittery bag came out. Harry cast diffindo spell on her bag, due to which its strap snapped and all of its stuff spilled out. That lady moved down to pick her stuff, but Sirius put confundus charm on her, due to which she started looking towards the shop across the road. Harry immediately acciod half of her muggle money. The whole process took about five minutes.
They moved from there and Sirius removed disillusionment charm. "So how much money did we made?"
Harry counted then whistled in appreciation, "It's about one hundred and fifty pounds. That lady was rich."
"Hmm.. but my dear Harry we need more money. Let's look for our next target. Oh that man coming out of that muggle car looks rich. Let's follow him" Sirius said while putting disillusionment charm on himself and Harry.
They apparated to different parts of the city, and stole money from rich muggles all over London and some places nearby. By afternoon they had about 1,860 pounds.
After counting their money, Harry looked at Sirius. "Now we can proceed with our other plans."
They went back to Leaky Cauldron. From there they entered Diagon Alley. Harry looked around and found few differences. Like next to Owl Emporium there was a Joke Shop called Magical Clowns, and there were few food stalls on the way as well.
But their destination Gringotts was same as ever. Sirius moved towards the nearest Goblin to exchange their muggle money. After exchanging they had about 372 galleons.
Sirius looked at Harry who was yawning.
"Harry lets eat and rest now. We will plan other things tomorrow."
