Well, old story really, from the 1820’s. But it was discovered in a filing box.
This is something like the few times a forgotten piece of music or artwork by a master is rediscovered behind a desk or something. Don’t remember this happening with a long dead author other than this. The Tallow Candle
Are we *sure *this is HCA? That sounds far too uplifting an ending for one of his stories. I presume the tallow candle melted into its own self destruction, at least?
