Over in a corner of the room and under an expensive woven throw rug lay a creaking oak plank floor. Varnished once when new and nailed down tightly it now had become loose by age and long years of neglect. The butler kept certain things there hidden and well away from his employer's prying vigilance. One key was silver and the other gold. The gold key was false and opened nothing while the silver opened a door behind the south pantry's granite cabinet. To open the door required a strong back and heavy gloves but once inside the ladder against the far brick chimney brought one to the third floor. On the third floor was the library and located on the third stack, third book from the end facing right, rested the bronze key... with this key all other rooms became available and the one carrying it was able to move about freely, noiselessly.
