Gentleman Rogues & WIcked Ladies: A Guide to British Highwaymen & Highwaywomen

I'm in a different kind of reading rut - I keep picking up books that don't engage me.  Gentlemen Rouges & Wicked Ladies looked interesting in the Daedalus catalog, but it's all surface and no analysis.  After a quick description of the typical highwayman (which comes to the conclusion that there was no "typical" highwayman), Fiona McDonald provides biographical sketches of several famous ones.  Unfortunately, there's not a lot of documentation for most of these men and women, so most sketches amount to a page or two of speculation and rumor, one or two notorious crimes, and execution.  It's not a bad book, and might be a decent commute book, but it's far from memorable.
