When 14-year-old Kit arrives at Blackwood, a new and exclusive school for girls run by Madame Duret, she is frightened by an unsettling atmosphere of evil…. The climax of terror [in Down a Dark Hall] comes when Kit discovers what happened to the pupils Madame had exploited in previous schools. What first appears to be a juvenile Gothic romance turns into a disturbing fantasy about the invasion of a sensitive human mind by an alien intelligence.
