Buckingham Palace denies any impropriety with a minor on behalf of the Duke of York. But he may want to revisit his list of friends. The prince is cozy with mogul Jeffrey Epstein, who served 18 months for having sex with an underage prostitute. In a lawsuit motion filed this week, the victim says she had sex with the prince and famed legal eagle Alan Dershowitz. The latter roundly denounced the charge. But that doesn’t mean the case — or the publicity — will vanish.
