Query: Entertaining and biased

Howard Engel's treatment of the history of executioners is both entertaining and biased (as he readily admits). The book begins well with many an ironic turn of phrase and gallows humor but by the end, Mr. Engel's political bias has taken over. He seems to have a particular obsession with Fred Leuchter. How anyone could link so-called holocaust denial into a book which purports to give an overview of executioners is beyond me. The first half of the book is an entertaining read; the second half a hackneyed polemic.
