Thanks for putting me onto this site Bopstar, here's a quote you may or may not like (btw will have to grab a copy of your Restless Soul stuff, strong vibes).
-----------------------------------
"To realise the power of light and what it can do to the mind of the audience, visualize the following little scene. The room is dark. A stromg streak of light sneaks in from under the hall under the door. The sound of steps is heard. The shadows of two feet divide the light streak. A brief silence follows. There is suspense in the air. Who is it? What is going to happen? Is he going to ring the bell? Or just insert the key and try to come in?

Another heavier shadow appears and blocks the light entirely. A dim hissing sound is heard, and as the shadow leaves, we see in the dim light a paper slip onto the carpet. The steps are heard again...This time they leave. A strong light appears once more and illuminates the note on the floor. We read it asthe steps fade out in the distance;

'It is ten o'clock. Please turn off your radio. The Manager.'"
