A short film based on the Screwtape Letters written by C.S. Lewis. This is from a letter written in the first chapter about how to keep a subject in the right direction.

The Screwtape Letters is a work of Christian fiction by C. S. Lewis first published in book form in 1942. The story takes the form of a series of letters from a senior devil, Screwtape, to his nephew, a junior tempter named Wormwood, so as to advise him on methods of securing the damnation of an earthly man, known only as "the Patient."

Screwtape holds an administrative post in the bureaucracy ("Lowerarchy") of Hell, and acts more as a mentor than a supervisor to Wormwood, the inexperienced tempter; almost every letter ends with the signature, "Your affectionate uncle, Screwtape." In the body of the thirty-one letters which make up the book, Screwtape gives Wormwood detailed advice on various methods of undermining faith and promoting sin in his Patient, interspersed with observations on human nature and Christian doctrine.
