Ketil had not intended to return to Orkney, but when you work for Thorfinn Sigurdarson, you obey orders. Thorfinn wants him back to help with a visiting Abbot from Saxony, escorted by an old colleague of Ketil's. Then people who know the Abbot start dying, and Ketil must once again work with his friend Sigrid to find out why - and to face dark memories from his own past.
