The life of the prestigious English educational institution — Carne School — is closed, measured, and dull. Studies, sports competitions, dinner at the teachers’ on Saturdays.
The editorial office of the newspaper “The Christian Voice” receives an alarming letter from this quiet place — “My husband is trying to kill me.” The editor-in-chief asks his friend, George Smiley, an employee of a secret agency who is on vacation, to find out to what extent the suspicions expressed in the letter correspond to reality. But Smiley will be too late anyway — the author of the letter is already dead. In the quiet English backwater, devils awaken.
