Well, that was not all true. Without Harry's blood in the house, the curse Bill had woven so expertly would not have taken effect. He was incredibly proud of the development of this karma curse. His superiors had commended him on it, added it to Gringotts" wards. Goblins usually bit off their tongues than complimenting a wizard. The sharing of sensation was easy, child's play almost. But only with Harry being kicked out of the place he had called home had the second curse kick in. For years now, decades even, the Dursley family would suffer from bad fortune. Nothing life-threatening, of course. Harry would never abide that. But things simply would not go their way. Since Bill had complete control over Harry's vaults, as per the teenager's insistence, he had used a surplus of one of the accounts to buy the lease to the Dursleys" house. While he would have gladly kicked them to the curb, he knew that Harry would never be as vindictive. Also, homes in a good muggle neighbourhood were suitable investments. He had purchased half a dozen, two of whom he had equipped to become safe-houses. So, no matter how out of luck the family would be, they would not have to live in the streets. Beyond that ... well, they had to work their way up, clamour for food by possibly accepting demeaning work, just to gain enough money. The day they felt honest regret for what they had done to their nephew, the curse would lift. Bill was not holding his breath.
