At the end of a bitter winter, a delegation arrives to investigate the monks of St Lazarus. Andre, a Knight of the Templar Order, and his young scribe, Christian de St Armand, have been sent by the King of France to oversee the investigation. When an elderly monk dies under strange circumstances, Andre and Christian start to unravel the mystery at the heart of St Lazarus. Hampering them at every turn is Rainiero Sacconi, the Pope’s ambitious inquisitor. He seems determined to condemn the community of monk. But why? By the time the secret of St Lazarus is revealed, hypocrisy and violence will be exposed. And for Andre and Christian, the investigation will turn into a fight not only for their souls, but also for their lives.
