Harry then made a few little gestures with his right hand, softly called out, "Obliviatus Obscura Revealus!" before tapping the Prime Minister in the middle of his forehead with his right index finger. Then stepped back and away.
The Prime Minister sat there appearing stunned for a moment before suddenly taking a deep breath of air. He suddenly grabbed the arms of his chair and swayed a bit as a look of amazement passed over his face.
After a few moments the look of amazement was replaced with one of fury.
Suddenly he shot to his feet and slammed his fists onto the top of his desk. Staring off into the distance, he snarled, "That... that... bastard!"
Lady Muriel jumped back in fright before exclaiming, "Mister Prime Minister!"
The Prime Minister, not seeming to have heard his personal private secretary while staring off into the distance, snarled even more venomously, "That... traitorous... prick!"
"John!" exclaimed Lady Muriel. "Your language!"
Harry, in the mean time, had calmly walked back to his chair and sat down to wait out the Prime Minister's furious rant.
The Prime Minister, finally hearing Lady Muriel, visibly got himself back under control before more calmly saying and sitting back down,"I apologise, Muriel. I... was just... surprised."
The Prime Minister took a few more moments to close his eyes calming himself before, opening his eyes again, he picked up the ledger and handed it back to Lady Muriel.
"Thank you, Muriel," he said. "I will call if we need you again."
Knowing a dismissal when she heard it Lady Muriel stiffly responded,"Thank you, Mister Prime Minister." And walked out.
'Not a happy lady,' thought Harry.
After Lady Muriel closed the door behind her the Prime Minister looked up at Harry and said, "I thank you for telling me this, Harry."
"You're welcome, Sir," Harry replied but, sensing a dismissal coming up, said, "However, the information will do you no good when Fudge returns for his next visit."
The Prime Minister thought about that for moment before saying,"He'd just do it to me again, wouldn't he?"
"Yes, Sir," replied Harry. "Before you could even open your mouth. Surprise would be on his side."
Then Harry went on, "I expect he will also be back sooner rather than later. I expect he's going to come and find out why his little listening device has failed."
The Prime Minister glanced down at the little trinket on his desk before looking back up at Harry and saying, "What can I do to stop it?"
"I'm sorry, Mister Prime Minister, you can't," said Harry slowly shaking his head. "You have no way to protect yourself from it."
The Prime Minister was thoughtful for a while before looking back up at Harry and saying, "What if we..."
Suddenly there was a flash and 'poof' sound from the fireplace.
Harry spun around just in time to see Fudge step through wearing a chequered suit with a lime green derby on his head.
Harry immediately thrust his right hand at the man and said,"Stupefy!"
Fudge collapsed to the ground on the spot.
"What on earth was that?" exclaimed the Prime Minister.
Turning back to him, Harry softly said, "A spell to knock him out. He'll be out for a while until I wake him."
Rising from his chair, Harry walked over to Fudge's body and started rifling through his pockets.
Finding what he was looking for he removed something from one of the man's pockets.
Holding it up, Harry showed it to the Prime Minister, while making the'Shhh' signal with an index finger vertically over his lips. It was a trinket identical to one of which Harry had already dealt.
The Prime Minister clearly understood Harry meant him not to say anything, so wisely kept silent. However, he was also clearly furious.
Harry then cast an almost silent spell on the object. He hesitated a moment before placing a second one on it. And then a third.
"Well, that happened faster than I thought," Harry suddenly said. "I didn't expect him to come checking for at least a day."
"And, sorry, Sir," continued Harry. "For not saying something but I couldn't risk anyone back at the Ministry from overhearing.
"However, I don't think there will be," he went on. "This is Fudge's doing and he won't want anyone else knowing what he's up to."
Reaching for his telephone the Prime Minster said, "I'll have security deal with him. I want to..."
"No, Sir!" interrupted Harry.
Hesitating, the Prime Minister turned back to look at Harry and quietly asked, "Why not?"
"Firstly, Sir," replied Harry, "he's a wizard. Nothing your security services have can hold him. Secondly, when he doesn't return, the Ministry will send through Aurors, magical police, to look for him. Thirdly, we can use this to our... your... advantage."
Dropping his hand back to the desk the Prime Minister said,"Explain."
"I can use the same spell on him that he's been using on you," explained Harry. "I can give him similar... hypnotic... instructions to make him believe he successfully replaced his listening device.
"I've already placed a spell on the device to stop it from listening in, and replaced it with one that provides false information back to him. I've also removed the charm on it that makes you want to keep it on your desk."
"Okay, I'm with you so far," mused the Prime Minister. Gathering himself and speaking more authoritatively, he said, "However, the man is still a traitor; and there is still the matter of sedition within the magical world."
"Yes, Sir," said Harry. "But the sedition is greater than you think."
The Prime Minister frowned and said, "Then you'd best tell me who else is involved."
Seeing his opportunity, Harry went in for the kill.
"Fudge here," he said tapping the man with his toe, "Is only what you've seen of it. He, and a great many others, believe the magical world is nobody's business but theirs. Almost everyone in the magical world agrees with him. And, overtly or not, they nearly all work to keep the mundane world ignorant."
"WHAT?!" the Prime Minister near bellowed.
