The harbor bell tolled twice before dawn and Mara found the lighthouse keeper dead beside his lamp still burning bright. No storm had risen yet the door stood open with salt on the threshold and boot prints crossing upward slowly. Inside the logbook lay open beside a cold cup while the final page named Elena Voss in fresh black ink. Mara had buried Elena last winter beneath white lilies yet her signature curved across the margin elegant and alive tonight. A radio crackled from the dark gallery reporting calm seas clear moonlight and no vessels expected before the morning tide. Then every clock above the cliffs stopped together and somewhere below the rocks a woman laughed once before silence returned.
