Deming's themes revolve around deception and self-deception, loneliness, and good intentions gone awry. Most of his stories occur just before or after the Civil War. In almost every tale, however, Deming shows his characters looking back toward the mountains, from the Mohawk or St. Lawrence Valley, or from lonely settlements on the edge of the forest, or across Lake Champlain.

Few Adirondack writers have been so convincing in conveying the keen isolation of life in the northern forest and its peculiar effects on the human mind. The wilderness community is cruel, fostered by ignorance and isolation. In the end, the mountains, seemingly a neutral backdrop against which individuals confront a collective morality, are the real source of his inspiration.
