“The Screwtape Letters” at the Long Center explores spiritual warfare from the perspective of a demon.

“The Screwtape Letters” is a smart, provocative and wickedly funny theatrical adaptation of the C.S. Lewis novel about spiritual warfare from a demon’s point of view.

The play, set in an eerily stylish office in hell, follows the clever scheming of one of Satan’s senior tempters, Screwtape. He advises his nephew, a junior tempter, on enticing a human “patient” toward damnation. In this topsy-turvy, morally inverted universe, God is the enemy and the devil is “our father below.”
