The latest chapter in the saga haunting the House of Windsor could be called “The Prince and the Peppercorn.” Prince Andrew, who recently relinquished his formal titles after new revelations about his relationship with convicted sex offender Jeffrey Epstein, is under pressure to vacate his royal digs where he lives nearly rent-free near Windsor Castle. The demoted duke occupies Royal Lodge, a sprawling mansion that eclipses its modest name, for the sum of a single peppercorn a year — a nominal figure that dates back centuries to when the spice was rare and fetched a heftier price.
