The Bat (1959)

An old dark house, a hidden room, a killer with metal claws, and Agnes Moorehead treating the whole thing as an inconvenience. Vincent Price is in it and is possibly the murderer. The pleasure is entirely architectural — corridors, panels, stairs. Krypts build the same way: Finnish death-doom as a floor plan, riffs that turn corners you did not know were there. Count the doors.
