The Mysteries of London was a best-selling novel in mid-Victorian England, published in four volumes. This is the third volume. Initially serialized in weekly installments, they were the forerunners of today's soap operas. Known as "Penny Dreadfuls", they had no claim to literary brilliance but offered readers entertainment and excitement in the form of vice, poverty, wealth, virtue, mystery, romance and scandal in every combination and reached a mass audience. - Summary by Lynne Thompson
