a Mandrake scream (Harry Potter)

Wormtail walked to the door for the Potter house and dropped a note, a note that will change his life, a note that explained his errors, a note that will help bring about Voldemort's downfall, a note which would change history, and then wormtail walked away and promised he'd come back tomorrow to face James, Sirius, and Remus and to answer any questions that the note didn't.

later that day James Potter went outside in his invisibility cloak like he always did on Monday nights, and saw the note addressed from Wormtail and picked it up, he quickly read throw it and gasped at every word it said, he, of coruse, ran back inside to show Lily the letter and she couldn't believe what she read, but still she quickly wrote two letters and ran to her owl and attached the letters to it, (which were addressed to Remus and Sirius) once Remus and Sirius arrived they started talking all night and next morning until they heard a knock on the door.
