Hey! So I need help finding a story. It's about Hermione going to Hogwarts under polyjuice potion or some sort of disguise for the order so she could gather information on Slytherin. She is sorted into Slytherin and I think maybe? her last name is Slytherin in the story, but I'm not sure. Anyways, later on in the story she sleeps with Draco, but in the morning the effect has worn off, and Draco tells her he's know she was Granger the whole time. Please help me find this story! Thank you!
