The grim history of England's bodysnatching trade: "Lennox's thorough exploration is riveting" (Naomi Clifford, author of The Disappearance of Maria Glenn).   From the string of murders committed by Burke and Hare, a pair of ghouls who are still the stuff of pop culture legend, to the lesser-known but equally gruesome grave-robbing exploits of Henry Gillies, William Patrick, and Joseph Grainger, here is the fascinating true chronicle of England's "Resurrection Men."   During the winter months of 1742-1832, selling fresh cadavers to anatomists up and down the country, all in aid of medical advancement, was the surest way to earn a living for desperate men. After all, anatomy schools would pay high prices for corpses to dissect--the fresher the better. And they asked no questions as to their origins. This resulted in the criminal underworld of the "Sack 'em up Men" who left behind disinterred churchyards and burial grounds, and spread fear and horror throughout the United Kingdom.   In Bodysnatchers, Suzie Lennox unearths the truth behind the macabre tales, separating fact from folktale, and setting the record straight about Britain's gruesome, often forgotten history.
