Old barrel keys are heavy in the hand. Most have a round or oval bow, though two brassy ones sport criss-cross shapes instead. All have rounded shafts, pin holes of varying diameter, and idiosyncratic teeth. Shaped entirely unlike the keys I can get copied for a buck-fifty at the local hardware store. One is stamped J. MICHALIK PRAHA. Did that key travel with my mother and her parents in 1939? So did the sideboard where I keep china, the one with a cabinet to which I long ago lost the key. I try every key twice, but the Czech cabinet remains locked. Maybe it's better that way. I know it contains the silver goblet from my wedding, a marriage long ago undone. No one gets to know what else might be inside.
