"Both novels also include several elements from the gothic novel, including the haunted house, the clairvoyant child, and the grieving widow-bride of The Dead Letter and the tower room and sleepwalking governess of The Figure Eight. The gothicism may come as a surprise to some readers, but it probably should not if we recall the blood relation of detective fiction and gothic horror in Poe's work. The gothic mode is always oscillating between the concealment of secrets and their dramatic revelation, and we can think of detective fiction as a more rationalized patterning of the same process."
