Another memory comes, not of the final time I saw Ligeia but a week before she disappeared, something mundane yet vivid. The mystery of memory. There's surely some scientific explanation for why the brain decides Don't let go of this. I've read novels and cannot recall a single character's name and yet I remember a red bicycle glanced once in a hardware-store window, a mole on a stranger's chin, a kitchen match lying beside a hearth. These remain, as does Ligeia reaching into her locker, a book crooked in her arm sliding free.
