The Last Gasp takes us to the dark side of human history in the first full chronicle of the gas chamber in the United States. In page-turning detail, award-winning writer Scott Christianson tells a dreadful story that is full of surprising and provocative new findings. First constructed in Nevada in 1924, the gas chamber, a method of killing sealed off and removed from the sight and hearing of witnesses, was originally touted as a "humane" method of execution. Delving into science, war, industry, medicine, law, and politics, Christianson overturns this mythology for good. He exposes the sinist.
