John Harmon returns to England after years in exile to claim his inheritance: a great fortune and a beautiful young woman to whom he is betrothed, but has never met. When Harmon's body is pulled out of the Thames, all of London is fascinated by the mystery of the murdered man and his unclaimed riches. Social-climbers, lawyers, teachers, a money-lender, men and women both honest and villainous will all become embroiled in this tale of love and obsession, death and rebirth.
