Title: Up In Smoke
The term "up in smoke" refers to the process of burning something, in which much of the mass of the object being burned disappears into the smoke, hence it goes "up in smoke". The term is often used to refer euphemistically to something destroyed with little or no value retained, often of things which do have substantial value, but are often very flammable, such as paper money.
Sara: This isn't The Tell Tale Heart -- it's the Cask of Amontillado.
The Tell Tale Heart and The Cask of Amontillado are macabre short stories by author Edgar Allen Poe, now considered classics of Gothic literature. The former is about someone going insane, committing murder, and then overwhelmed by guilt, and the latter is about a horrific revenge attained by walling someone up in a small basement room to die there.
