At 4 Privet Drive, things were starting to get desperate. The Dursleys all had faith that this was just a temporary blackout. But as time wore on, that faith was starting to weaken. Because of their belief that this was just a temporary disruption of services, they hadn't bothered to go to the store and horde food until the shelves were empty. So they ate what they had on hand, cooking it on the back yard barbecue. When they ran out of food, Dudley began catching neighborhood dogs for food. Petunia wasn't very efficient at butchering and much was wasted. Because of this, the Dursley's had quickly run through all of the friendly, easy to catch dogs in the neighborhood long before anyone else got the same idea.

Finally, they realized that they would be forced to take to the road in the hopes that they would find food.

"Mom, I'm hungry," complained Dudley.

"Yes dear, we're all hungry," replied Petunia. "Why don't you catch us a nice yummy dog so we can eat again."

"Until you do, why don't you talk about something else besides food, son" added Vernon.

"But I smell Roast Pork," whined Dudley.

"Come to think of it, so do I," admitted Vernon.

"Maybe a restaurant burned down," offered Petunia, gazing at the burned out landscape. They were walking through a neighborhood that had burned recently.

"It's coming from over here," said Dudley stepping into a burned building. There was a partially burned body within. It was not burned to ash. It was more like cooked meat. He bent over the body sniffing.

"Get away from that, Dudders. It's nasty," said Petunia as she saw her son pull a piece of meat off of the corpse.

"It's delicious!" exclaimed Dudley as he grabbed another handful of meat.

"Dudley, you stop that this instant!" screamed Petunia.

"Would you rather starve?" asked her husband. "Save some for me son."

"It's a dog eat dog world now, mom. Would you rather eat or be eaten?"

Eating burned corpses tided them over for a while. But soon they ran out of burnt corpses and the pangs of hunger returned. . . .

"But we can't!" pleaded Petunia

"We don't have any choice!" roared Vernon. "We haven't found a decent body in a week and we've got to eat!"

"Dog eat dog world, Mum," said Dudley.

"But it's wrong!" pleaded Petunia.

"Look, people are the only food available. It we don't start feeding our selves, someone is going to use us to feed them selves" her husband replied. "Look, you won't have to do any of the killing yourself. Dudley and I will take care of it. All you have to do is keep quiet so we can take them by surprise."

"Just keep quiet and hidden here. When someone comes down the road, we'll jump out and get them." Said Dudley gleefully.

It all went according to plan. It was dusk when a couple came walking down the road. Dudley and Vernon jumped out of the bushes and clubbed them to death. When Petunia came forward to dress their kill, she made a startling discovery.

"Celia? Vernon! It's the Martins!" screamed Petunia, tears streaming down her face.

"Well, I never liked them anyway," said Vernon.

"Eat or be eaten, mum," said Dudley in a tone that sent chills down her spine.

Luella's friends, the three remaining members of the "Slytherin Four" had failed utterly in their search for her parents. They would never know that their friend's parents had died here by the road-side. For the Dursleys had eaten all of the evidence.

The Dursleys continued to roam across the countryside killing anyone that they could for food. Eventually they stumbled across a house that made a perfect base of operations. For some reason it was difficult to see until you were on the doorstep. Who ever had lived there before had been some sort of survivalist-luddite. The house had never been fitted with modern plumbing or electricity, so it made for a comfortable living. Who ever had owned it had been fabulously rich too as demonstrated by the fancy paintings, furniture, and carpets.
One day, they were sitting in the living room eating what had once been a teen-aged girl when they heard a loud "CRACK!" coming from the master bedroom. Petunia and Vernon dove behind the couch. They had long feared that a larger group of cannibals would discover their lair and turn the tables on them.

"What the fuck!" said a female voice.

Dudley picked up the thigh he had been munching on. He had gnawed enough of the flesh from around the knee that he could use the thigh-bone as the handle of a club. He ducked to the side of the door so that he could get the drop on whoever came through the doorway. A middle-aged woman came through the doorway and walked past Dudley, not seeing him.
"Who ever's hiding behind that couch come out with your hands up!" she said.

Dudley took advantage of his opportunity and hit her over the head with the thigh of his previous victim!
