The polished dark granite floor yields seamlessly to slick granite walls leaving not the slightest crevice to begin scratching an escape. Polished steel bars cover a small vent high on one wall. Dark rich grain in the highly polished granite serves only to emphasize the depth and quality of the stone. There is no escape from this cell, only release.
