By sticking to the tried and tested Longitude formula, Philbrick has missed a slight trick or two. The epicenter of the whaling industry was Nantucket, a small island off Cape Cod; most of the whales were in the Pacific, necessitating a huge journey around the southernmost tip of South America. We never learn why no one ever tried to create an alternative whaling capital somewhere nearer. Similarly, Philbrick tells us that the story of the Essex was well known to Americans for decades, but he never explores how such legends fade from our consciousness. Philbrick would no doubt reply that such questions were beyond his remit, and you can't exactly accuse him of skimping on his research. By any standard, 50 pages of footnotes impress, though he wears his learning lightly. He doesn't get bogged down in turgid detail, and his narrative rattles along at a nice pace. When the storyline is as good as this, you can't really ask for more. --John Crace, Amazon.co.uk
