What makes a jobless single mother on benefits into a half-billionaire within 5 years? Selling your soul to Satan, that's what! 

Harry Potter and the half-billionaire
JK Rowling has been named as the world's richest author by Forbes, with earnings of an estimated £3 million a week or £5 per second.
The Harry Potter creator is unlikely to be adversely affected by the global credit crunch as the movie adaptations of her Potter adventures have generated £2.1billion at the box office and there are still three more films to come.

The former single mother on benefits, who has sold more than 375 million books worldwide, receives an undisclosed cut from the film profits. In addition she receives around £100 million from merchandising.
The writer admits that, despite her talent ands creativity, she is indeed incredibly fortunate: "I'm the luckiest woman in the world. Immensely privileged."
The 43-year-old mum of three has earned approximately £560 million of which the £160 million she raked in over the last year was said have been more than the next nine best-selling writers, including James Patterson, Stephen King, Tom Clancy and Danielle Steel, put together.
