An utterly compelling historical mystery, in the tradition of Umberto Eco and John Fowles. The setting is England in the 1660s. Oliver Cromwell's short-lived republic is a thing of the past, and Charles II has been restored to the throne. At Oxford's New College, fellow Robert Grove is found dead under suspicious circumstances, and a young woman stands accused. We hear from four witnesses: a physician hungry for fame, the son of an alleged traitor, the king's chief cryptographer, and a renowned Oxford antiquarian - only one of whom is telling the rather extraordinary truth. Who is it? Pears' skillful plot-weaving will keep you guessing until the final seconds.
