The Dead Room

On a summer night in 1829, an ancient mansion on the Cornish coast stood still, listening to the last breath of its mistress – Lady Treverton – who had left the mortal world, leaving behind a grieving husband, a small daughter named Rosamund, and many unanswered questions. What did she hide from everyone until her death, and what did she manage to confess only on her deathbed, dictating a message to her maid Sarah Lyson? Why does Sarah lack the courage to deliver the letter to her master, instead hiding it in one of the abandoned rooms and immediately leaving the house? And why, sixteen years later, does she try to prevent Rosamund from returning to her childhood home and entering the room?
