The Dead Secret

A dying mistress forces her terrified maid, Sarah Leeson, to help conceal a confession that could overturn everything, then dies before the letter can be destroyed. Years later that hidden paper still waits somewhere inside the crumbling Cornish house of Porthgenna Tower. When Rosamond Treverton, raised as a wealthy heiress, returns to the estate with her blind husband Leonard, the buried truth about her own parentage begins to surface. Wilkie Collins fills the search with atmosphere, guilt, and the slow dread of a secret that will not stay hidden, anchoring the mystery in the eerie, locked Myrtle Room. It stands as an early example of his mastery of suspense and concealed identity. Available free as a PDF and EPUB.
