A/N: I don't own Harry Potter.
This was written for the prompt "Mundungus Fletcher" on the Snakes and Ladders Challenge and the prompt "44: Pickpocket" on the If You Dare Challenge.
No one could ever accuse Mundungus Fletcher of having morals. He was a liar and a thief. He was a crook to his core.
Anyone who lets someone like him into an old house filled with very rare, very ancient, very valuable objects deserves what comes to them.
At least, that was what Mundungus told himself the first time he entered Number 12 Grimmauld Place. He had hit the jackpot! Sirius Black didn't even need all of that stuff, anyway.
So, he swiped some goods. And, yeah, there was a locket. And, yeah, he let Dolores Umbridge take it. He had to save his own skin, didn't he?
Things worked out in the end. The locket was found and destroyed. Harry Potter killed You-Know-Who. A new age of peace and prosperity began.
Mundungus Fletcher took advantage of that prosperity by picking people's pockets. After all, that would never change.
