Book excerpt: For two centuries the question has persisted: Was Meriwether Lewis’s death a suicide, an accident, or a homicide? By His Own Hand? is the first book to carefully analyze the evidence and consider the murder-versus-suicide debate within its full historical context. The historian contributors to this volume follow the format of a postmortem court trial, dissecting the case from different perspectives. A documents section permits readers to examine the key written evidence for themselves and reach their own conclusions.
