Fred and George entered the kitchen of Number 12, Grimmauld Place, and sat down straight across from Harry Potter.
"No, I am not going to be your guinea pig for whatever you have been planning."
Fred crinkled his nose. "What has guinea pigs have to do with anything?"
"No, we, dear investor, would like to borrow a certain piece of parchment."
"If you catch his drift."
"We would like to analyze it to reproduce for our…ahem…project."
Harry raised his eyebrows. "Why don't you ask Moony or even Padfoot? I'm sure they would be more than happy to help."
"Wonderful idea, old chap…"
"…if only we knew who they are…"
"…then we'd be all set."
Harry stared at them, muttering under his breath. "I didn't tell you? I must have told you…"
The twins exchanged looks. "You know who the marauders are?"
"What's this about the marauders?"
Harry looked over to the door, "Hello Sirius."
"Nothing, nothing," said Fred, hastily. He and George both stood up to leave.
"It's not nothing, Siri. These two were wondering who the makers of the fine Marauders' Map were."
Fred and George made identical shushing noises, and flapped their hands at Harry, who simply grinned.
"It's all right, I know all about the map," said Sirius, laughing.
"Talking about the Marauders' Map, Paddy?" asked Remus, leaning on the doorframe, arms crossed.
"Yep, Remmy. The dear old map." Sirius sighed.
"Oh yes," Lupin said, catching sight of the twins, "Harry told me you two gave the map to him."
"You told a professor?" screeched Fred.
"Now, Fred, George," Harry said, backing away from the advancing twins, "There is a perfectly good explanation for it…" He gave up, and said, "Gred, Forge, meet Moony and Padfoot." Then, he leapt up, and ran out of the room.
