She looks like a harmless massage therapist with tired eyes, but Alicia Vane's long fingers know the points on a man's body that, when pressed, stop the heart forever. Nursing a childhood grudge against her traitorous father, the girl long ago turned the spa into a stage for perfect murders that are written off as sudden heart attacks. By day, she dissolves into the scent of lavender oil, and by night, she keeps an encrypted diary where victims' initials sit alongside chessboard coordinates. Alicia doesn't take money for her services — she only needs the truth, because her victims are always guilty of the same sin. But she has one rule that might one day cost her freedom: she never kills those who genuinely repent. In her empty apartment, a ficus named Mr. Silence rustles its leaves quietly — the sole witness to her nightmares.
