The year is 1703. The place: the Carolina settlement of Charles Town. Matthew Corbett, professional 'problem solver,' has accepted a lucrative, if unusual, commission: escorting a beautiful woman to a fancy dress ball. What should be a pleasant assignment takes a darker turn when Matthew becomes involved in a murder investigation. A sixteen-year-old girl has been stabbed to death on the grounds of a local plantation. The suspected killer is a slave who has escaped, with two family members, into the dubious protection of a nearby swamp. Troubled by certain discrepancies and determined to see some sort of justice done, Matthew joins the hunt for the runaway slaves. He embarks on a treacherous journey up the Solstice River, also known as the River of Souls.
