In the darkness of 13th Century Europe, the most precious wonders of the Christian world lie in a small church in the great ruined city of Constantinople, the spoils of a failed Crusade. The crown of thorns, the spear that pierced Jesus' side, the shroud bearing the imprint of Christ - all lie in the mysterious Chapel of Pharos, untouchable treasures beyond earthly price.

On the other side of the globe, Petroc of Auneford sails into the sprawling Pool of London for the first time. He has left his old monastic world behind for that of the enigmatic Captain de Montalhac - purveyor of fine relics and other exotic trinkets to anyone with sufficient money and desire.

But for Petroc, the trip is soon blighted by tragedy. Grief, however, is no guard against greed, and with rumours of the sale of the relics of Pharos growing, the Captain needs Petroc?s help. The great powers of Christendom are gathering ? all covet the power of the relics ? and Petroc finds himself right in the eye of the storm.

Stretching from the streets of London to the brothels of Venice and all the way to ruined palaces of Constantinople, THE VAULT OF BONES is an epic tale of faith, power, money and revenge.
