Oh, 'The Sister Under the Stairs' is such a haunting little gem! The sister in question is Clara, a spectral figure who lingers in the shadows of the old Victorian house where the story unfolds. She’s not just a ghost—she’s a tragic figure, eternally bound to the place where she met her untimely end. The way the author weaves her presence into every creak of the floorboards and flicker of candlelight is masterful. You almost feel her grief seeping through the pages.
What really gets me is how Clara’s backstory unfolds in fragments—letters tucked behind wallpaper, diary entries hidden in the attic. She was the black sheep of the family, accused of a crime she didn’t commit, and her desperation to clear her name becomes this heartbreaking thread. The ambiguity of whether she’s seeking justice or vengeance keeps you guessing until the last chapter.
