Harry sat in his bed looking at the Marauder's Map and eating cookies by wand light.

Ron suddenly sat up. "Spiders! There's-There's spiders! Spiders. They want me to tap-dance. I don't want to tap-dance."

Harry knew Ron wasn't even awake. He smiled. "You tell those spiders, Ron."

"Right, yeah. Tell them. I'll tell them." He lay back down and snored.

Harry looked back at the map and saw Argus Filch then he stopped. Peter Pettigrew. Harry remembered McGonagall saying Pettigrew was dead. Harry got up and put his shoes on.

Harry went along the darkened corridor with his lit wand and map. He watched the map and saw Pettigrew was supposed to be right in front of him coming towards him. He shined his light everywhere as it came closer skirting around him. Harry turned wildly and jumped surprised until he realized he was looking in a mirror. He looked all around him but saw nothing.

He looked down at the map and saw Severus Snape coming around corner. "Mischief managed. Nox!"

A wand came on and Snape stood there. "Potter. What are you doing wandering the corridors at night?"

"I was sleep-walking." Harry said.

"How extraordinarily like your father, you are, Potter. He, too, was exceedingly arrogant, strutting around the castle."

"My dad didn't strut. And nor do I. Now if you don't mind I would appreciate it if you could lower your wand."

Snape did surprisingly. "Turn out your pockets." Harry paused. "Turn out your pockets."

Harry brought out the blank map.

"What's this?"

"Spare bit of parchment."

"Oh, really? Open it." Harry did so. "Reveal your secrets." The map had words appear on it. "Read it."

"Messrs. Moony, Wormtail, Padfoot and Prongs offer compliments to Professor Snape and…"

"Go on."

"And request he keep his abnormally large nose out of other peoples' business."

"Why you insolent little-"

"Professor." Lupin appeared.

"Well, well, Lupin. Out for a little stroll in the moonlight, are we?"

"Harry, are you all right?"

"That remains to be seen." Snape said snatching the map. "I have just now confiscated a rather curious artifact from Mr. Potter. Take a look, Lupin. This is supposed to be your area of expertise. Cleary it's full of dark magic."

Lupin looked at the parchment. "I seriously doubt it, Severus. It looks to me like it's merely a parchment designed to insult anyone who tries to read it. I suspect it's a Zonko product." "Snape tried to take it back but Remus kept it from him. "Nevertheless, I shall investigate any hidden qualities it may possess. It is, after all, as you say, my area of expertise. Harry, would you come with me, please? Professor, good night." Remus led Harry back to his classroom.

"Come in. Now, I haven't the faintest idea, Harry, how this map came into your possession, but quite frankly, I am astounded that you didn't turn it in. Did it ever occur to you that this in the hands of Sirius Black is a map to you? No?"

"No, sir." Harry said.

"You father never set much store by the rules, either. But he and your mother gave their lives to save yours. Gambling their sacrifice by wandering around the castle unprotected with a killer on the loose seems to me a poor way to repay the! Now, I will not cover for you again, Harry, you hear me?"

"Yes, sir."

"I want you to return to your dormitory and stay there. And don't take any detours. If you do, I shall know."

Harry had turned to go but then looked back. "Professor, just so you know, I don't always think that map works. Earlier on it showed someone in the castle. Someone I know to be dead."

"Oh, really? And who might that be?"

"Peter Pettigrew."

"That's not possible."

"It's just what I saw." He turned. "Goodnight, Professor."
