Letters and the Gunpowder Plot

I have bundled together three resources which will be useful for the study of letter writing and in particular how a letter saved the day when we look at the intrigues surrounding the Gunpowder Plot.
This resource has more relevance today because of the new drama series entitled Gunpowder which stars Kit Harington of Game of Thrones fame who plays Robert Catesby, the brains behind the plot to blow up the Houses of Parliament. Here Harington reveals he is a direct ancestor of Catesby.
