Write a detailed description of a mysterious scene inside a mansion with a tile mosaic and mahogany doors.

Walls of gleaming white marble sweep like seagull's wings in a wide, massive circle. A tile mosaic of dark material is embedded in the floor, the type of substance that releases a most satisfying *click* when walked across wearing metal-shod boots. A short passage leads east, and there is a narrow corridor northwest. Gleaming mahogany doors lead west, and a spiral stairway allows access to other levels.
