The two documents here transcribed as the core of a fuller account than any hitherto compiled of the escape from Government custody of a future martyr, the priest Ven. Thomas Tichborne, have in fact been in print since 1897. But though their previous editor, J. C. Jeaffreson, noted that these papers afforded new information unknown to Challoner when the latter published his brief account of the escape, yet Catholic historians who have written since the documents were printed have not been aware of them. Accordingly, since they first appeared in a context which Catholic writers have, not surprisingly, overlooked, there are grounds for republishing both documents freshly transcribed from the original manuscripts (now in the present writer's possession) and for elucidating them with the aid of notes and two sketch-maps, to retell more vividly a small incident played out in the streets of Elizabethan London, which cost two Catholics their lives.
