There had to be a thief.

Harry Potter was sure of it.

Every time he had brought a new pair of pyjama shorts, they ended up going missing.

And there was only one suspect for this crime.

His fianceé. Hermione Granger.

He didn't want to admit that his wife was a criminal mastermind but the evidence was mounting against her and he was beginning to have serious doubts about her innocence.

The first pair went missing a few weeks ago, shortly after they had moved in together.

He had worn them that night, and had put them in the laundry, but they hadn't come back to him..

It was just as well really because Harry couldn't bear to wear anything else. The pyjamas were so soft! He felt naked without them on.

The second set disappeared a week later, when he had returned from an Auror mission. He had put them to be washed, and then they had disappeared as soon as they had been cleaned.

So Harry had just bought another pair.

But there was no mistaking that they had gone missing the same day he had piled them to be washed.

And now a forth pair had gone missing.

Forget the washing machine – he needed to get Hermione Granger arrested.

She had to take responsibility for these thefts.

Heading to the Ministry, he knew where his suspect would be - the Department for the Regulation and Control of Magical Creatures.

As Harry entered the room, he could see that Hermione was already busy looking through a file folder full of parchment. She was wearing her usual jeans and a jumper, along with her glasses and an expression of pure concentration on her face.

Heading over to her, he coughed to get her attention, "Hello, Hermione."

Hermione turned around and looked up at him, surprised, and then smiled.

"Oh, hello, Harry," she said cheerfully. "I wasn't expecting to see you today."

"Hermione Granger. You're under arrest for Grand Theft."

Hermione's face fell. "What?" she asked, confused.

"You stole my pyjamas," Harry explained, a little indignantly. "Four pairs in fact. We're talking thousands of Galleons worth of stolen merchandise."

Hermione frowned at him. "That's impossible."

"Impossible? I thought you were a criminal mastermind!"

Hermione laughed, though Harry found it hard to tell if she was being serious or not.

"Well, maybe I am," she admitted. "But that doesn't make me a thief."

"Why do you keep taking my pyjamas?" Harry asked.

"Well... because you look so much better in bed without them!"

Harry blushed furiously.

"I'm sorry, Hermione, but I can't allow you to go free. You must pay for your crimes."

"How will you do that, Auror Potter." she asked, fluttering her eyelashes.

"Meet me in the DMLE Conference Room in 10 minutes... and make sure that you are ready for your punishment!"

Hermione nodded knowingly. "Of course, Harry. But what exactly did you have in mind?"

Harry winked, knowing exactly what kind of 'punishment' he had in store for her.
