The lace-pillow lay upon Clara’s lap like a dead, white bird. Her bobbins clicked with a dry, insect-like persistence, casting a web of intricate, fragile threads that seemed to hold the quiet of the room together. Outside, the gray fog of the harbor pressed flat against the windowpanes, blurring the masts of the idle merchant ships into skeletal fingers.

Instead, she kept her eyes fixed on the neat, geometric progression of the mesh. It was a pattern of her own design, named 'The Harbor Walls,' though it possessed none of the granite strength of the breakwater she could hear the tide thrashing against in the distance.
