The Guardian regularly reprints articles from its archive (it started life as the Manchester Guardian in 1821). Today it has an article by Mary Shelley in which she recounts the genesis of her most famous work, Frankenstein, for a revised edition published in 1831 (the best known version of the work). The article is actually the preface she wrote for the new edition.
Did you notice that portrait of Mary Shelley? Her shoulders seem bizarrely elongated. Almost as if her body had been . . . say, waaaaait a minute. Maybe Frankenstein is not fiction at all. Could it be . . . possibly . . . thinly veiled autobiography???!
