The notion that physical objects may sometimes best be hidden by being left in plain sight, but camouflaged or disguised in some way, was famously propounded by Edgar Allan Poe in his celebrated short story, "The Purloined Letter." A wordplay incarnation of this idea is found in the fabrication of "insider" sentences, sentences akin to charade sentences in which occult non-sentence words are spelled out in consecutive letters of the sentence, albeit usually broken up into two or more parts by the sentence's word breaks and/or punctuation.
