Luna and her father thanked Madame Herophile profusely before they left.  In turn, she made it clear that she would not be disappointed to see another article about her shop in The Quibbler sometime soon.  Xenophilius made no promises.

He guided Luna into the back room and said, “Our next stop requires a bit of . . . delicacy.  It might not be a good thing if certain individuals saw me entering the offices we are about to visit.  It might even lose us a story.  So,” and here he pulled a tightly-folded cloak from beneath his robe and shook it out.  It glimmered in an odd, silvery way, almost like sunlight on water.

Luna had never seen this cloak before.  “What is it?” she asked.

“Watch!” her father replied, slipping on the cloak.  His body disappeared from view as the cloak fell over his frame, and when he pulled the hood over his head, he vanished completely.

Luna gasped, her hand over her mouth.  An invisibility cloak!  She had no idea that he owned one.
