- Once again, everyone but Harry gets to go to Hogsmeade for the holidays.
- But this time, Potter has a plan.
- He sneaks through the snow wearing his invisibility cloak, not realizing that it doesn't cloak his footprints in the snow.
- George and Fred Weasley see Harry tromping through the snow and pull him aside.
- They present him with the Marauder's Map, which shows the presence of everyone inside Hogwarts. It's like a magical paper version of Google Earth.
- The map shows a secret route to Hogsmeade, which Harry takes.
- If we had a secret passage to a village full of magical candy, well…it wouldn't be too long before we were too large to fit through the secret passage.
