Although fictionalized, the life story of Joshua Bowen … [in Underground Man] is based on fact: the sources cited in the author's postscript are evidence that Milton Meltzer has done the thorough research that distinguishes his nonfiction titles…. Spare in construction, the book has historical interest, dramatic appeal, and an aura of suspense and danger that emanates from the events rather than by the declaration of the author.
