"Millicent Barnes, age twenty-five, a young woman waiting for a bus on a rainy November night. Not a very imaginative type is Miss Barnes, not given to undue anxiety or fears, or, for that matter, even the most temporal flights of fancy.

All of which is mentioned now because, in just a moment, the head on Miss Barnes' shoulders will be put to a test. Circumstances will assault her sense of reality and a chain of nightmares will put her sanity on a block. Millicent Barnes, who, in one minute, will wonder if she's going mad."
