Luna spends a November evening with an elderly lockmaster at the Soo Locks in Sault Ste. Marie, Michigan. He insists on counting every vessel that passes through, even those that aren't there. He shows her his logbooks spanning sixty years, each page filled with names of ships that never existed—yet the water remembers them. The lockmaster's quiet compulsion, his worn-out chairs, the sound of water against concrete. When he takes her to the lower viewing platform at midnight, she sees the shadow of a freighter pass through the lock without a sound, without lights, without a wake. A story about the obligation of witness, the weight of being the one who notices. No resolution. Just the water, still running.
