Title: Jack and Jill
Summary: The war with Voldemort is long since over, but now a new foe is rising from the shadows. 'Jack' and 'Jill' are two killing masterminds, and it's up to Harry, Ron and Hermione to figure out who they are before they wreck the uneasy peace of the Wizarding World. As people begin dying, and there's so clues as to who is behind it except for the notes that the murderer/murderers leave behind them. Can the Golden Trio solve the puzzle before Jack and Jill get to their target, whoever it may be.
This is a story I'm thinking of writing, based loosely on Jack and Jill by James Patterson. Let me know if I should write it. :)
