In Duke Hamlyn's Murder, Elerren Demesne's army has aligned to invade Syharrill Demesne, as King Lynton is running short of patience to know his brother Prince Edwarren's fate. Syharrill's queen, Mariona, is desperate to avoid war. She sends Lady Keial to extricate Edwarren from Hallberk Castle's dungeon where Edwarren has been held for four months, accused of the murder of Duke Hamlyn. Lady Keial finds herself on the run with a very ill Edwarren.
