I have been driving myself crazy trying to ID the following short story, which was published sometime before 1970 (and probably before 1960): PLOT: An alien spaceship lands on a devastated Earth (I don’t remember how this came about). The aliens are amazed to discover human survivors. They survived, however, because they were already dead – they’re vampires! I distinctly remember the last scene, where the main character (a ship’s doctor, I believe) commits suicide rather than let the vampires get him. Any help would be appreciated. There are a number of SF short stories that I would like to read again but can’t identify. I don’t wanted to bombard this board asking about all of them, so does anyone know any oinline forums/message boards/whatevers that might help? Something like a Department of Lost Stories?
