The narrator of The Bottoms is Harry Collins, an old man obsessively reflecting on certain key experiences of his childhood. In 1933, the year that forms the centerpiece of the narrative, Harry is 11 years old and living with his mother, father, and younger sister on a farm outside of Marvel Creek, Texas, near the Sabine River bottoms. Harry’s world changes forever when he discovers the corpse of a young black woman tied to a tree in the forest near his home. The woman, who is eventually identified as a local prostitute, has been murdered, molested, and sexually mutilated. She is also, as Harry will soon discover, the first in a series of similar corpses, all of them the victims of a new, unprecedented sort of monster: a traveling serial killer.
