Gareth, Gwen and family have come to Ysbyty Cynfyn, a hospitaller commander, at the request of Saran’s brother, Iago. They arrive to discover Iago has died and many monks are ill, as are Gareth, Llelo, Meilyr and Taran. Gareth is recovered from his illness, Gwen is attending the funeral of Helen, the monk Desmond’s mother, with Dai as a pallbearer. Dai thinks the coffin is rather heavy when one of the front pallbearers slips in the mud at the edge of the grave causing the casket to overturn revealing a second body under Helen’s. It is the physician, Everard. And thus begins another murder investigation for Gareth and family. To compound matters, there is a war going on.
