Only one reveals the extraordinary truth. Each tells his own version of what happened.

We hear the story of the death from four witnesses: an Italian physician intent on claiming credit for the invention of blood transfusion the son of an alleged Royalist traitor a master cryptographer who has worked for both Cromwell and the king and a renowned Oxford antiquarian. A fellow of New College is found dead in suspicious circumstances. Oxford is the intellectual seat of the country, a place of great scientific, religious, and political ferment. Charles II has been restored to the throne following years of civil war and Cromwell's short-lived republic. An ingenious tour de force: an utterly compelling historical mystery with a plot that twists and turns and keeps the reader guessing until the very last page.
