An Instance of the Fingerpost (Unabridged‪)‬

Set in Oxford in the 1660s – a time and place of great intellectual, scientific, religious and political ferment – this remarkable novel centres around a young woman, Sarah Blundy, who stands accused of the murder of Robert Grove, a fellow of New College. Four witnesses describe the events surrounding his death: Marco da Cola, a Venetian Catholic intent on claiming credit for the invention of blood transfusion; Jack Prescott, the son of a supposed traitor to the Royalist cause, determined to vindicate his father; John Wallis, chief cryptographer to both Cromwell and Charles 1l a mathematician, theologican and inveterate plotter; and Anthony Wood, the famous Oxford antiquary. Each one tells their version of what happened but only one reveals the extraordinary truth.
