What was once a royal palace is now a museum of French culture and history attracting 3 million visitors every year.

In this episode we take a Musketeer training course to discover the real man behind the fictional D’Artagnan. We find out why Champagne bubbles (and if it’s good for you), then discover that Marie Antoinette was not the frivolous dim-wit that some would have us believe. We examine a strange weapon created by an inventive assassin, then investigate the suspicious death of a king’s mistress. And finally, we visit an historic French observatory to recreate a discovery that connects humanity to the stars.
