Mary, Queen of Scots and Who Wrote the Casket Letters?: Vol. II

A book which explores the possibilities of who wrote the series of letters from Mary to Lord Bothwell, which incriminates the two of them in the murder of Lord Darnley. Much speculation has been applied to this grouping of letters, which were supposedly written by Mary, but which she denied and which some historians corroborate, citing a difference in handwriting in the letters, suggesting forgery.
