The Disappearance of Aimee Semple McPherson
BBC News tells the story (briefly, but with good pictures) of this famous kidnapping hoax from the 1920s. Note that McPherson claimed she was drugged with a chloroform-soaked rag and then abducted. This alone suggests her story was bogus since, as Wikipedia notes, the chloroform-soaked rag as an incapacitating agent is a cliche of crime fiction. The reality is that it's very difficult to drug someone in this way with chloroform.
