Rat and tomb
Harry Potter jogged quickly down the muggle streetwhere his mental powers had led him. He was invisible to all but his allies. Two of whom followed, beneath his invisibility cloak, a few paces behind. Harry stopped outsode the house where he knew his quarry resided and fully entered the man's mind, to see what he saw.
He was speaking to a man. It was dark and hard to see what was going on so Harry decided to boost his concentration to add an audio feed. Ron and Hermione stopped beside him, stilll under the cloak, and waited.
"...you accept?" Said the man Harry was watching through the eyes of.
"Y...Y...Yes," stuttered the other man, who was short and podgy, "But I want to know why you have chosen me!"
"Why? Because only you are too pathetic to be able to do it. At least, in mist people's eyes."
"But S..." the podgy man began, before being interrupted.
"I have told yuo not to use my name. It is unworthy of your lips. You are to call me DeKay."
"My apologies DeKay. But I'm not sure if I'll be able to place it in the great hall."
"Your other form would be in the least conspicuous?" Asked DeKay with an audible sneer.
"Well, no but..."
"But nothing you will do as instructed. Be gone."
Harry terminated the link and turned to the solid air beside him and said "He's sending the rodent after Hogwarts. Right now."
Hermione's voice answered grimly, "Then we must go in now."
"Are you ready Ron?" Harry asked with a glance at the door.
"Definitely. Let's go," Ron said confidently, before pulling off the invisibilty cloak and putting on the black, hooded cloak he had brought for their task. Hermione and Harry did likewise.
The man that Harry was after was just taking his seat when the door to his living room was blown iinwards, knocking out his "servant". he jumped up, imediately realising who the leader of this group of three was. He flung the killing curse at him, but it merely dissipated on impact. He jumped behind his sofa in an attempt to keep Potter from hitting him with a spell. But the three assasins merely blew the man's sofa apart, and before his quarry could react, Harry Potter silently cast "Sectumsmpra" on Snivellus Snape.
Main job done, Harry moved on to the bonus task. He kicked Pettigrew's corpse so that his face pointed straight up. He cast a memory charm on him, transformed him into a rat, wiped his remaining memories to be replaced with the memories of a sewer rat, then enervated him. The rat scampered off imediately upon waking.
Severus Snape's home on Spinner's End became his tomb, as Harry, Hermione and Ron burned it to the ground. job done they silently walked out of the Muggle settlement, apparated to the Burrow, and began planning their assault on Voldemort's "Impenetrable" fortress of solitude.
