Open doors admit the light from many windows.
A semi-obscurity is all, and through this the figure passes, but hesitatingly still, and with pause after pause, till a certain door is reached--a closed door--the only door which is closed in this part of the house.
Here it stands--stands with profile to the panels, one ear against the wood.

One minute--two minutes--five minutes pass.

Then a hand goes out and touches the knob.

It yields; yields without a sound--and a small gap is seen between the door and its casing.

This gap grows.
