"anonymous" delivery In the morning, a package is found outside James, Sirius, Remus, and Lily's door, addressed to The Marauders. It contains notes written in Peter's handwriting on how to make Firewhisky. These notes include a notation to use magical water using the spell "Aguamenti". And a note telling them that the grain is in sacks in the brewery, and that they can come get them any time. It's a pretty thick folder, containing a lot of information.
