Abut the Mobiliarbus in the last chapter: it was Ivy Crane I believe who commented that Mobiliarbus is actually used to lift trees ("arbus" is Latin for tree) instead of boxes, like Remus did. My excuse for that mistake has to be that my Latin doesn't go any further than "veni, vidi, vici"... I just remembered that Hermione uses it in book 3, to replace – you guessed it – a tree... and I assumed it worked for all kinds of objects. Apparently not.

So sorry for that mistake, but it was made entirely unintentionally. To make up for it, a new chapter!

Tuesday October 26, 1981.

"So Black was the Potters' Secret-Keeper?"

It was a cold but sunny day in October, a few days before Halloween. Big orange pumpkins were visible in Hagrid´s garden patch. Sirius could see them through the windows of Dumbledore´s office. James was sitting in a chair behind him, and they were waiting for Dumbledore, Sirius had no idea why. He turned around and looked at his best friend. James looked tired and pale, as if he hadn't slept for a few days.

"You look like a wreck" said Sirius.

"You try looking good when every moment could be your last and your wife and child could be murdered any minute" James replied angrily.

"Sorry, keep your hair on. I was only trying to make conversation!"

An argument was prevented by Dumbledore, who entered the room. He looked just as tense and exhausted as James, but managed to produce a little smile. He sat down and waved to Sirius to do the same.

"I've found a solution to the problem" he told James. "The best thing to do would be the Fidelius charm." "Of course!" James muttered, and his face lightened up a bit.

"Excuse me", Sirius interrupted. "The what?!"

"The Fidelius charm" James explained. "With this charm, secret information can be locked inside a person, the so-called secret-keeper, and no one can find it out, unless the secret-keeper reveals it. Lily and I are planning to go into hiding, and the Fidelius charm would be the best way to prevent Voldemort from finding us."

"It would be the best way. Voldemort can look for you for ages and never find you" said Dumbledore. "Who will be the secret-keeper?"

James glanced quickly at Sirius. "Sirius" he said.

"Are you sure?"

"Yes, Sirius is planning to go into hiding himself, aren't you?"

Sirius nodded. Dumbledore still seemed worried. "Are you sure you don't want me as your secret-keeper? I would be happy to do it, and that is not just politeness."

"No, I'm sure. It'll be Sirius."

"Shall I do it? Maybe it's the best way…"

"No", said James determined. "I´ll do it myself. Then I know for sure it goes right."

"Very well, if you insist. But I believe you must be going, I've got other things to do. I'm sorry." Dumbledore lead them down the stairway to the main entrance hall and let them alone. James looked at Sirius. "Do you want to do it?" he asked.

"Are you sure you want me?" Sirius asked back.

"Who else? I trust you almost more than Dumbledore."

"I've got a better idea. Let's take Peter" Sirius suggested as they walked their way up to Hogsmeade Station. 

"Peter?!" James replied.

"Yes, Peter. He's totally inconspicuous. Almost everybody knows I'm your best friend so it would be likely I know where you're hiding. But Peter won't be connected with you, at least not so fast."

You're right, Peter is a better choice. I´ll send an owl immediately so I can perform the charm this night. The sooner the better, isn't it?"

That night, very late.

"It is done, my master. The Potters choose me as their secret-keeper. I know exactly where they're hiding."

"Very good, Wormtail. You have been a good servant. Maybe you'll be rewarded some day."  A high cackling laugh followed these words.

"Thank you, master…"
