This collection belongs to the Springbok Radio horror tradition, rather than being another title for an American Inner Sanctum episode. The programmes can be approached individually, with the opening atmosphere helping to lead the listener into a different story each time.
South African broadcasting references identify The Creaking Door with Springbok Radio in 1964-1969 and producer Michael Silver. One collector log labels its network differently; that unsupported label is not used here. Exact dates and cast remain unassigned to the six Heritage Radio Vault recordings until recording-specific evidence is available.
Choose any complete story in this small selection. Compare the presentation with Inner Sanctum Mysteries if the sound of a threatening doorway appeals, while keeping the two productions distinct.
