His is a name all too familiar to Montanans, to all Americans, in fact: Meriwether Lewis. On October 11, 1809, three years after he, William Clark and the Corps of Discovery completed their transcontinental trip of America and following a presidential appointment as Governor of the Louisiana Territory, Lewis died from not one, but two gun shot wounds. In the hopes of finding answers, Dr. David Peck and his wife, Dr. Marti Peck, who co-authored the book, "So Hard to Die: A Physician and a Psychologist Explore the Mystery of Meriwether Lewis's Death" help unravel the mystery.
