Researchers discover 600 secretive letters, many intended for lovers, that were never delivered.
The 300-year-old letters locked away in leather trunk shed light on life in the 17th century stories.
The trunk of undelivered letters dating back more than 300 years will be studied by experts who say they will give a unique glimpse into life in 17th century Europe.
They say the historical postal sack - which was recently discovered - has 2,600 missives from aristocrats, spies, merchants, actors and ordinary people - many of whom may have been fleeing religious persecution from Sun King Louis XIV.
The international team of researchers will be drawing on all of their knowledge and special scanning techniques to unlock the stories of scandal, gossip and intrigue hidden in these letters - 600 of which are unopened.
