I don´t blame Mark Twain´s daughter for concealing this book! In two words, I define it as an acrimonious tract. Even me, who am not squeamish at any rate, indeed hostile to all religious matters, was profoundly astonished by its contents. A gloomy side to the author of so many funny tales, read this volume at your own risk. I´m serious, your former opinion, respect and affection for Mark Twain is likely to be capsized forever. Mine was, actually! Now he occupies a fair place far above the one I had previously given him due to my ignorance.
