Mystery of the stolen document is a detective story that brings lights to the complicated relations of mind and reality, ingenuity and analytic ability, fancy and imagination. Suspense is the main factor: original ideas, "the robber's knowledge of the loser's knowledge of the robber." It challenges "the well-digested idea of centuries" with a fresh and intelligent look. "It was just possible this mystery troubled him so much on account of its being so very self-evident." This is how a really unique genius, Edgar Allan Poe, sees and solves the mystery. "When I wish to find out how wise, or how stupid, or how good, or how wicked is any one, or what are his thoughts at the moment, I fashion the expression of my face, as accurately as possible, in accordance with the expression of his, and then wait to see what thoughts or sentiments arise in my mind or heart, as if to match or correspond with the expression."The Purloined Letter by Edgar Allan Poe A story in four languages: English, French, Spanish and Persian.
