Hell hath no fury like a former spy spurned. On the verge of becoming the leader of Monaco, Prince Albert, perhaps the world's most eligible bachelor, hired a former FBI agent to dig up dirt on his behalf and find out which of the prince's friends might turn against him. Now, it’s the spy who is turning against Albert, alleging that the prince owes him hundreds of thousands of dollars for work and dishing on Albert in a new lawsuit obtained by The Times of London. In his investigation, the spy Robert Eringer found an associate of the prince who boasted that he had a tape of a woman performing a "sex act" on Albert at his 40th birthday party. Albert's attorney says that Eringer is trying to "extort" money from his client.
