It may be one of the hottest days of the year, but that doesn't keep the swarm of tourists from lining up to visit Britain's popular Hampton Court Palace. As the team of warders opens up some of the building's 1,300 rooms, gardener Graham Dillamore and his team give a "haircut" to the estate's world-famous, 300-year-old hedge maze. And back inside, we explore the creepiest part of Hampton Court--the Haunted Gallery--where people have reported seeing the ghost of Catherine Howard, who was executed after just two years of marriage to Henry VIII. Follow the team at Hampton Court, in the palace, and on the grounds, as they keep the palace running on a hot summer day.
