Re: Old Victorian building
In the 1970s one of our offices was a Gothic country house surrounded by parkland. The main hall had a large staircase by a two storey window. When leaving at night you had to switch off the hall lights at the top of the staircase - then sense your way down the staircase heading for the neon glow of the downstairs switch. This was in an opposite wall - along which were projecting marble shelves with sharp corners at crotch height.
On dark nights there was some light from the moon through the big window - fractured by the waving of tree branches. If the office mousing cat decided to scamper across your path - you had the hairs on your neck going vertical.
