The little metal box it.hides in plain site behind the velvet painting of a Zulu warrior slightly off center a bit to the right.
The warrior. Hmmm.No The vault.

A naked dwarf. He struggles quietly at midnight to  gather and drag my blocks of raw marble across crystaline floors to the vaault then
He stands there for hours before clcking the numbers.Clack goes the handle. Success.

The hinges have rusted since last deposit. He looks furtively over his shoulder as the metalic groan turns to a squeek. Abra cadabra.
Time to do work. Stealthy old fella he whistles while he works.

One block,two, three and so.
He forces the stones through a the four square door.
Rubs his hands together. Wipes the drivle from his chin
Then walks out the door backwards. The one he came in.

My vault is reloaded with pleasure and pain.
So I can write poetry again and again.
