In 1845, famed explorer Sir John Franklin set out with two ships in search of the elusive Northwest Passage; the expedition vanished, leaving only a few artifacts and several lonely graves for subsequent searchers to find. When, 140 years later, Beattie (a forensic anthropologist) began to look into the expedition's fate and the causes of its failure, he not only uncovered evidence of cannibalism but—by temporarily opening the graves to take tissue samples—proved that some or all of the crew had ingested debilitating levels of lead from poorly tinned food. This book is a digest of Beattie and Geiger's book for adults, Frozen in Time (1987), combined with a dramatized historical reconstruction plus plenty of paintings and color photos— including macabre photo portraits of three exhumed, startlingly well-preserved corpses. Like others in the ``Time Quest'' series: a fresh, vividly illustrated look at modern methods of archeological research. (Fiction/Nonfiction. 11-14)
