Dahl Roald. The Landlady

A brilliant short story by Roald Dahl.A young man Billy Weaver is looking for accommodation. He is inexplicably drawn to a house where the landlady seems to be expecting him. The house and the landlady seem friendly and welcoming, and he wants to staying there. Signing the guest book, two names disturb him. Where has he heard them before? Why aren't there any other guests?
What actually happens is left very much up to the reader, but Roald Dahl, the master of this kind of story, gives us all the clues we need to concoct a grisly ending.
