Summary
That Hideous Strength, published in 1945, is the final novel in C.S. Lewis's acclaimed Space Trilogy. This work concludes the adventures of Dr. Elwin Ransom as he faces a sinister conspiracy on Earth. Unlike the previous books set on Mars and Venus, That Hideous Strength takes place entirely on our planet, blending elements of dystopian fiction, Arthurian legend, and Christian theology. The novel centers around Mark and Jane Studdock, a newly married couple drawn into a conflict between the nefarious N.I.C.E. organization and a small group of allies led by Ransom. Lewis uses this story to explore ethical questions related to science and technology, the dangers of unchecked power, and the role of faith in modern society—themes that continue to resonate with readers in the 21st century.
Plot
That Hideous Strength follows Mark and Jane Studdock, a newly married couple in post-war England. Mark, a sociologist, is recruited to join the National Institute of Co-ordinated Experiments (N.I.C.E.), a scientific organization with sinister motives. Meanwhile, Jane experiences strange prophetic dreams and seeks help from a group at St. Anne's Manor led by Dr. Elwin Ransom, who is connected to supernatural forces.
As Mark becomes more deeply involved, he discovers N.I.C.E.’s true nature and identity as a front for dark supernatural powers with plans to control humanity. Jane's visions lead the St. Anne's group to search for the awakened wizard Merlin, who they believe can help them counter N.I.C.E.'s influence.
Using violence and manipulation, N.I.C.E. takes control of the town of Edgestow while also searching for Merlin, believing he will join their nefarious cause. Mark gradually becomes disillusioned with N.I.C.E. and attempts to escape, while Jane undergoes spiritual experiences that lead her to embrace Christianity.
In the climax, Merlin, empowered by angelic beings, infiltrates N.I.C.E. headquarters disguised as an interpreter. He casts a spell that causes chaos and destruction among the N.I.C.E. leadership. As the organization crumbles, Mark escapes and reunites with Jane at St. Anne's, where they reconcile and begin to heal their marriage.
