Mark Twain once remarked, " . . . Letters from the Earth will never be published . . . in fact, it couldn't be, because it would be a felony." And, indeed, until 1962, most of these remarkable pieces were considered too controversial for publication. This is vintage Twain--a sharp, witty, imaginative, and sometimes wildly irreverent satire of his times. Satan writes a probing letter to his fellow archangels Michael and Gabriel about the inconsistencies of human religious faith, in the title story. In this posthumously published book, Twain uses his characteristic acerbity and lucid powers of observation to investigate the nature of existence.
