SLAP!

Sirius woke with a start.
“Ouch,” he muttered, rubbing his cheek.

Ha-ha-ha!

He opened his eyes and saw the Marauders surrounding him.
“What was that for?”
James shrugged, “You were asleep.”
“So? Let me sleep!”
“No, can’t. Snivellus is out wandering.”

He sat bolt upright and looked at the map. He was there all right. First floor, right near the bathroom.
“I wonder what’s in there?” he asked.
James shrugged again, “One way to find out.”

They jumped off the bed. Remus, Sirius and James got under the cloak with great difficulty, and Peter morphed into his rat form.
