CASKET LETTERS
DISCOVERED 1567 (OR NOT)
 

The Casket Letters might or might not have been forgery.

If they were real, they were eight letters and a bunch of poems written by Mary Queen of Scots to her lover James Hepburn, the 4th earl of Bothwell, proving that they were planning to kill Mary's husband Henry Stewart, the earl of Darnley.

However, many historians think the Casket Letters, or at least the part of the letters that held the evidence against Mary, were a fake.

In any event, the letters vanished in the 1580s.

The correspondence was called the Casket Letters because they supposedly had been found in James Hepburn's silver casket. The date? June 20, 1567.
