This is a neat little 24-page book about the burglary of King Edward I's treasure room in 1303. There remains some mystery what exactly happened, it has lots of drama, interesting characters, scandal, cover-up, and a great sense and feel of the time. Very entertaining, includes a hand-drawn map and two relevant manuscript pages.

There also appears to be a 2005 book about it by Paul Doherty called "The Great Crown Jewels Robbery of 1303". ( )
