Two of Britain's greatest monarchs are profiled.

The history of this grand 500-year-old palace is inextricably tied to the lavish lifestyle of King Henry VIII and the doomed fates of his six wives.

During a three-month period in 1888, a knife-wielding serial killer murdered six women on the streets of Whitechapel. Their throats were cut and their bodies horribly mutilated. He was never caught and his identity remains one of the world's greatest crime mysteries. In the years that have passed since Jack the Ripper's killing spree, many high-profile suspects have been suggested, yet the fact remains that none of them can be placed at any of the crime scenes. Now, journalist Christer Holmgren believes that he has found a suspect who can not only be linked directly to one of the murders but also whose daily routine could be consistent with all the other deaths

Exactly 100 years ago, the world of the British manor house was at its height. It was a life of luxury and indolence for a wealthy few supported by the labor of hundreds of servants toiling ceaselessly "below stairs" to make the lives of their lords and ladies run as smoothly as possible. It is a world that has provided a majestic backdrop to a range of movies and popular costume dramas to this day, including PBS' "Downton Abbey." But what was really going on behind these stately walls? "Secrets of the Manor House" looks beyond the fiction to the truth of what life was like in these British houses of yesteryear. They were communities where two separate worlds existed side by side: the poor worked as domestic servants, while the nation’s wealthiest families enjoyed a lifestyle of luxury, and aristocrats ruled over their servants as they had done for a thousand years.
