The book they refer to, David Cordingly's Life Among the Pirates is excellent. I remember it well because I was half way through it and left it on plane so had to buy another copy. One of the key messages I picked up was that the "romantic" pirate era, much beloved in Hollywood, which delights in celebrating them despite the fact they were mass murderers, rapists and terrorists, was actually very short. Within a couple decades, the Royal Navy had established control of the Caribbean and rendered the pirates marginal. What's puzzling to me is that I love reading about pirates too: they were the provisional wing of the emerging capitalist nation state, and most of the time they were stealing from Spain, and the Spanish had stolen the silver from the natives in the first place, so it all seemed OK. Some of the tales of navigation, amphibious assault and naval action are genuinely astonishing though. Thanks for the pointers, they've gone into my Amazon wishlist.
