Wormwood is the junior tempter addressed by Screwtape in C.S. Lewis’s The Screwtape Letters.
The book takes the form of letters from Screwtape, an experienced demon, to his inexperienced nephew Wormwood. Their correspondence discusses how to tempt a human being away from faith and virtue.
Lewis published the work in 1942, during the Second World War. Its ironic viewpoint lets him satirize human weaknesses, bureaucratic thinking, and distorted moral reasoning by presenting them from a demon’s perspective.
Screwtape is Wormwood’s uncle and mentor, while Slubgob is a senior figure in their infernal organization. The fictional demons are not presented as historical people.
